3 Working with plastic pipes and fittings Transport and storage of plastic pipes W R O N G R I G H T Plastics are materials sensitive to impact and crushing at low temperatures. The temperature limit depends on the relevant material. PP-R PVC-C +5 C PB 0 C VPE C Below these temperatures pipes and fittings would have to be protected particularly from impacts, crushing and other external mechanical stresses.! Safety instruction Plastic pipes and plastic fittings must be protected in principle from external influences. Direct sunlight, impacts and compressive stresses should be avoided. The pipes and fittings must be left in their packing until used. They should not be stored out of doors. GEORGE FISCHER 5

4 INSTAFLEX The modern versatile piping system A full range of pipe and fittings makes the INSTAFLEX system highly versatile. Allowing prefabrication and being lightweight make the installation of an INSTAFLEX system highly cost effective. 6 GEORGE FISCHER

5 What is INSTAFLEX? The versatile pressure piping system for building services For use on: Hot & cold water services Heating systems Chilled water Compressed airlines The INSTAFLEX system has been designed for use as a complete building services piping system which provides a solution to the problems faced by traditional materials namely: No corrosion No encrustation/limescale No noise emmission Long service life High flexibility Fast assembly Lightweight Launched in 980 into mainland Europe and into the UK in 995 this system has provided installers and designers with a flexible system which meets the stringent demands of modern building design and construction. Material Manufactured from polybutylene (PB), a high performance plastics material, which was specifically developed for use in piping systems for potable water. Its inherent charachertistics make it ideal for this purpose and for other building services applications. Range A full range of pipe and fittings are available with adaptors to join onto other piping system components. Pipe & fittings 6-0mm Pipe-in-sleeve Accessories & jointing equipment Valves Jointing & installation The INSTAFLEX system utalises three complimentary jointing techniques: socket fusion electrofusion compression fittings Each of which have advantages depending on the installation in question. Most installation tend to incorporate more than one type of jointing method. Due to the flexibility of the system and the material's lightweight significant savings can be made on installation time and costs. Technical advice & support George Fischer's expertise and technical knowledge in the piping system field is recognised worldwide. In order to assist designers and installers in the optimum use of the INSTAFLEX system the following support is available : On-site support & advice Design take-offs Certificated jointing training courses Technical support CAD Custom products GEORGE FISCHER 7

6 What is Polybutylene (PB)? Polybutylene is a thermoplastic from the polyolefine family. It is a semicrystalline material. Its density is in the range of other thermoplastics such as PE or PP. It has good mechanical properties and chemical resistance making polybutylene an important material for piping systems. PB is created by polymerizing butylene (C 4 H 8 ) and is, therefore, an ecologicaly safe hydrocarbon product. The material which we use, may be used with foodstuffs due to its safe stabilizing agent. The fittings and pipes are odourless and tasteless as well as physiologically safe. It is perfect for use in drinking water installations. Like PE and PP, PB belongs to the group of co-valent materials, whose surfaces do not swell and are not soluable. Solvent cementing is, therefore, not possible without special surface treatment. PB is, however, easily fused. Compression, socket fusion and electrofusion jointing can be used. Flexibility, even at low temperatures, high thermal stability make polybutylene a modern material. Not only for hot and coldwater distribution but also in industrial applications and compressed air. George Fischer are able to supply metric socket and electro fusion pipe, fittings and valves as well as mechanical joints in the following size range. socket fusion 6mm - 0mm o.d. electro fusion 6mm - 0mm o.d. The physical values shown in the table below are to be treated as guide values.

7 The E-modulus is the ratio of stress to strain in the elastic range of the material. Expansion loop comparison Although the coefficient of expansion for PB is not the lowest due to the material's flexibility (i.e. it's modulus of elasticity is by far the lowest), the ability to cater for any expansion or contraction is most favourable Using a typical example, with values expansion L 0m LBS Determining the expansion loop according to CEN/TC. 55/WG 5 C for: PB 0 PEX 2 PE 27 PVC-C 34 PP-R 30 Steel 94 Cu 54 Stl.Steel 6 Temp difference t = 50 C Pipe diameter d = 40mm Pipe length = 0m The expansion of L of the different materials is as follows: PB L = 65mm PEX L = 00mm PVC-C L = 40mm PP - R L = 90mm Steel L = 6mm Copper L = 9mm Stl. Steel L = 9mm using the formula LBS = C x L L x d where LBS = expansion loop leg L = primary pipe expansion d = outside dia.. of pipe C = factor Therefore, under the same conditions the expansion leg required for the different materials would be as follows: Material PB 50 PEX 760 PVC-C 360 PP-R 800 Steel 450 Cu 030 Stl. Steel 50 Expansion leg LBS As can be seen from the above the expansion leg required for PB is considerably less than all the other materials. Creep is the extension of a material in relation to time under constant load and constant temperature. Creep behaviour Creep behaviour is an important factor in plastic construction. It must be given special consideration with jointing and fastening techniques. It can be seen from the adjacent graph that with a creep test, where a weight is hung from a piece of PB its creep is slower than PEX Creep % 0 PEX PB Tensile strength 8 MPa (8 N/ mm 2 ) Temp. C Time in hours GEORGE FISCHER 9

8 σ = Sigma/Break The hoop stress in the pipe wall is the result of internal pressure. If this pressure is continuous the pipe will fracture with time Safety against breakage due to stress from internal pressure is given with the relationship between pipe wall stress to hoop stress. Minimum breaking strength «σ» The minimum breaking strength is given as the hoop stress.

Allowable permanent internal pressure in bar: s 6R P perm = (d-s) SF Hoop stress is based on a service life of 50 years and a constant operating temperature of 70 C, without considering the safety factor for: σ PB R 7.5 PEX 5.3 PP-R 3.

Comparision of flow characteristics The pipe wall thickness is determined by the hoop stress, the pipe outer diameter and the allowable operating pressure at C. Because at any given size the wall thickness of PB pipe is less than the other materials the flow velocity and pressure drop will be best.

Safety Factor.5 Temperature/Pressure rating The George Fischer INSTAFLEX system is manufactured from polybutylene which is a thermoplastic material. As the name thermoplastic suggests, it is affected by temperature. When the temperature of the liquid in the pipeline rises the material will soften and its ability to withstand pressure reduces correspondingly. To calculate the pressure rating at any given temperature the well known "vessel" formula is used in conjunction with the long term regression curves of the material. or where P = σ x x s SF x (d-s) SF = σ x x s P x (d-s) P = pressure in bar σ = hoop stress of material at any given temp. in M Pa s = pipe wall thickness in mm d = pipe o.d. in mm SF = safety factor Example What is the maximum pressure for a 0mm pipe carrying water at 70 C with a working life of 50 years? s = for 0mm INSTAFLEX pipe is 0mm SF =.5 d = 7.5 MPa taken from long term regression curve opposite.

11 Flange connections/unions Connection: plastic/plastic O-ring sealing unions or flange connections should be used in principle for detachable connection of plastic pipes or adaptors between plastic pipes and metal pipes or metal fittings (valves, pumps). Unions up to d 63 Flange connections up to d 0 High screw tightening forces are not required for making flange connections with O-rings. It is recommended to use torque wrenches to prevent excessive tightening of screws. Nominal values for the screw fixing of flange connections with O-Ring: Pipe external diameter mm Torque Nm Commercially available screws, nuts, washers. Washers should be used in general Connection: plastic/metal Flange seals are normally used in flange connections for the transition from plastic to metal, since the jointing faces of the metal flange are usually serrated. The screws should also be tightened with a torque wrench for flange connections with flange seals, in order to prevent damage to flanges or flange adaptors. The table below shows nominal values of torques required for the various pipe diameters. Pipe external diameter mm Nominal internal diameter DN mm Torque Nm GEORGE FISCHER 3

12 Firestop Firesleeves Product Specification Firestops are a one piece, one length stainless steel sleeve complete with closure tabs and slots, having an intumescent lining running the full length of the unit with 3 bands of Accoustic Foam adhered to the bore. The units are wrapped around the plastic pipes by hand and slid into the walls/partitions. In the event of a close proximity fire the Pacifyre fire sleeve lining of intumescent activates at 40 C and expands to over 6 times its own volume to create a fire proof seal between the pipe and the wall which prevents the spread of the fire between building compartments. The foam, whilst creating a smoke and accoustic seal against the pipe, allows for pipe expansion and building movement and is also an anti-vibratory material. Firestops can be fitted to either horizontal or verical pipework and although they can be freely moved into position, they will remain in place even on vertical pipework. Firestops do not give off toxic fumes or smoke in the event of a fire Firestops are asbestos free and do not contain any hazardous materials and there are no special precautions required for handling or installing the units. 4 GEORGE FISCHER

14 Selection of PB Pipe Systems The selection is based on the following diameters: The installed system shall be the George Fischer PB pipework system and shall have the following diameter pipework. Outer Diameter Inner Diameter All PB pipework sizes stated on the drawings refer to outside diameters. Workmanship, Finish & Appearance The finished tube shall be smooth, free of internal and external mechanical imperfections and internally shall have a smooth appearance. Packaging & Transportation The pipes should be delivered in coils or straight lenghts and the tubes shall be bundled by size in suitable bags or cardboard boxes, clearly marked with the purchase order number, material designation, size, total length or piece count and name of supplier. Pipe Joints The pipes and fittings should be entirely compatible with each other and the jointing should be carried out in strict accordance with the manufacturer's printed instructions. Unless indicated otherwise, the pipe joints in PB pipework should be made by socket fusion, electrofusion or compression. The assembly of these should be carried out in strict accordance with the manufacturer's instructions. Only fully trained installers should be used for assembling PB pipe systems. Trained and certified by George Fischer. (i) Socket Fusion Utilising the correct tools for assembly, heating and jointing times in accordance with the manufacturer's instructions. This shall only be carried out at a work bench, with the heating element securely fixed to the work bench. (ii) Electrofusion Utilising correct tools for assembly, heating and jointing times in accordance with the manufacturer's instructions. (iii) Brass Compression Fittings to include internal pipe sleeve as integral part of fitting with grip ring to hold pipe in place. Assembly in accordance with the manufacturer's instructions. This method shall only be used to connect to items of plant or to metallic pipework sections. Where directed, to enable disconnections to be undertaken, socket unions should be fitted on pipes up to and including 63mm outside diameter. Above 63mm outside diameter, flanged joints should be used. Note: Locations for demountable unions and flanges shall be as shown on the drawings. Screwed adaptor fittings should be used at screwed joints to appliances up to 2" nominal bore. PB flange adaptors having dimensions in accordance with BS 4504, should be provided for connection to pumps, tanks or equipment above 2" nominal bore. Pipework System The piping contractor should provide samples of the following for approval: - PB Piping - PB pipework regulation and isolation valves - PB Pipework bends, tees and tap connectors - PB cleaner and jointing equipment or (if applicable) compression fittings for use with PB. 6 GEORGE FISCHER

15 Orders for the pipework system should not be confirmed, nor should the the construction of the installation of the system proceed until these samples have been approved in writing. The approved samples should be retained on site for comparison with the work as actually installed. The connections to taps on sinks, worktops etc should be installed with the manufacturer's suitable outlet connectors. Arrangements should be made to ensure that the fittings and the PB pipe to which it is joined are guarded and secured in such a way as to be protected from undue impact or excessive torque. PB pipework can be connected to any heat source (for example domestic hot water storage calorifier or direct gas fire water heater). Cleaning In general the pipe should be flushed with mains cold water after finishing the installation. Disinfection Disinfection shall be carried out in accordance with Section 28 and the manufacturer's guidelines. Fire Sleeves Fire sleeves should be used where single PB pipes of mm outside diameter and above or multiple banks of pipes penetrate fire barriers. They should generally comply with the requirements of the local fire authority. (i) They should be constructed with an intumescent lining. (ii) Casings should accommodate the expansion of intumescent linings during fire conditions. (iii) Intumescent linings should expand inwards at a temperature of about 40 C and completely seal the openings against the passage of flames, fumes and smoke. Such linings should also be in accordance with the pipe manufacturer's requirements. Note: The pressure of the expanding intumescent lining may crush PB pipes. (iv) Individual sleeves mounted on vertical pipework should: - be of construction suitable for surface mounting - be installed on the pipe immediately below the barrier (the collar should be securely fixed to the sleeves, the sleeve and the flanged collar butted up against the fire barrier and the flange bolted into position) or similar. Installing the pipework system The contractor should: (i) Check that the exterior of the piping is marked at intervals not exceeding one metre with the manufacturer's name, type of material, pipe size and standard with which it complies. (ii) Check that all the piping and fittings supplied are uniform in colour density. (iii) Exercise particular care in their storage, handling and installation to avoid deterioration due to ultraviolet light and impact damage. The piping manufacturer's printed instructions should be rigidly adhered to in all respects of storage, stacking, handling and installation. The pipework should be supported as indicated upon the drawings and as detailed within the contract documents. It is essential that cleaners are correctly applied to the pipe ends and sockets prior to fusion and electrofusion jointing with cleaning pads changed regularly in accordance with manufacturer's instructions. After fusion jointing, a ring of Polybutylene will be visible on the outside of the pipe as evidence that a joint has been completed. After electrofusion an indicator pip will raise above the surface of the fitting as evidence that a joint has been completed. Great care should be taken to ensure that only the manufacturer's installation procedures are followed and in particular that the full cooling period is GEORGE FISCHER 7

16 maintained before any joint is considered to be complete. No pipework, or section thereof, shall have water pressure applied until the manufacturer's stipulated setting period has elapsed (a minimum of at least one hour after the last fusion joint). Where an existing heat source has to be maintained, with pipes either running parallel or crossing each other, thermal insulation should be applied. On no account should ladders, scaffold or other building items be propped up against the PB installation. Changes in direction can be achieved using the pipe's flexibility in accordance with the manufacturer's instructions. No thermally induced bending of PB pipes through the application of local heating should be permitted. All PB pipes should be supported by pipe clips or support brackets, the spacing of which should not exceed the maximum intervals as advised and confirmed by the pipe manufacturer. Where a pipe clip or support bracket is being used to support a number of pipes of different materials and sizes, the spacing interval between such clips and brackets should not exceed the smallest of the 'maximum intervals' stated or advised for each of the pipes being supported. PB pipework in exposed positions (or where distortion is likely to occur) should be supported using the piping manufacturer's standard pipe clip or support pipe carriers. Where PB piping is supported using other than the standard PB pipe clips, the supports should comprise steel split pipe rings with rubber insert, nippling rod nuts and washers with backplate as required, either fixed to rail support or building fabric. The test pressure should be maintained throughout the period of time of not less than one hour and not less than one and a half times working pressure. There should be no loss of pressure above that detailed in the manufacturer's handbook, to allow for the expansion and the seting in period of PB pipes, during the period the test is being carried out. The results of the pressure test should be recorded on a log sheet. Expansion Expansion loops or changes in the pipe direction should be allowed for at regular intervals in accordance with manufacturer's guidelines. Where expansion loops and changes in direction are impractical, fixed point assembly may be used on pipes up to 75mm diameter to prevent the PB pipes from expanding or contracting, in accordance with manufacturer's guidelines. Warning: Not all PB piping systems are suitable for fixed point assembly to resist the effects of expansion. Please consult the manufacturer before considering the use of this method. If fixed point brackets are being used to avoid longitudinal expansion of PB pipes, the installation instructions of bothe the pipe and bracket manufacturers should be adhered to. Fixed point brackets should be located at fittings and must grip the pipe on both sides of the fittings or according to manufacturer's instructions. Fixed point supports should be located at fusion or electrofusion fittings and meet the manufacturer's requirements to absorb forces and transfer them to the structure. Fixed points should not be located more than a maximum of 6m apart. Pipe support carriers shall be of semi circular shape to closely match the outside diameter of the pipe. Manufactured from galvanised or size plated steel. The coating inside and outside are to be of the same standard. The finish is to be smooth along the surfaces and edges to prevent damage to the pipes. When 8 GEORGE FISCHER

17 cut the edges of the carrier are to be filed smooth. The carrier is to be attached to the pipe by approved cable ties suitable to support the forces, at intervals recommended by the manufacturer (never more than 500mm). The carrier is not to be run over fittings, but to terminate 0-5mm short both sides with adequate support through cable ties and brackets. Only installers carrying a George Fischer training certificate shall be used for assembling George Fischer Polybutylene pipe systems. Water Treatment On completion of installation, the whole of the heating and primary hot water system is to be filled and after a satisfactory pressure and heat test is achieved, emptied and flushed clean of all foreign matter. When a clean water condition is proven, the system is to be dosed with an approved and recognised chemical scale and corrosion inhibiting agent. The dosing operation is to be carried out by an approved specialist and on completion certificates are to be submitted indicating the chemical used (and its characteristics) the percentage dosage introduced and all other relevant details required to maintain satisfactory protection. Immediately upon completion of the dosing process, notices are to be posted in plant rooms indicating that the system has been treated, the chemical used, the percentage concentration etc and particularly relevant information required by the Health & Safety at Work regulations. Prior to the dosing process commencing, the Contractor is to submit details of the company it is proposing to engage to perform the operation, complete with all relavant information regarding the type of chemicals to be used and the method. Dosing by the mechanical contractor or any other organisation not a specialist will not be permitted. GEORGE FISCHER 9
