2 INTRODUCTION PIPE FITTINGS 02 OneSteel is Australia s largest distributor of Pipes, Pipe Fittings, Valves and associated accessories. The OneSteel distribution network offers more than outlets throughout Australia, comprising: OneSteel Piping Systems Capital cities and selected regional centres OneSteel Fire Systems OneSteel Metaland Capital cities, specialising in fire and associated plumbing services Regional cities and towns in all states The "Pipe Fittings" catalogue is part of a comprehensive series of catalogues, brochures and data sheets which are provided to our customers and associated industry groups. This catalogue describes our range of pipe fittings which are principally manufactured in carbon steel, cast ductile iron and malleable iron. A separate catalogue describes our range of stainless steel pipes and fittings. In Australia we have two broad groups of standards which govern the design and manufacture of our products, viz: British / Australian Standards American Standards Generally covering cast iron and mild steel fittings for low-to-moderate pressures, for coercial and light industrial applications. In this group we also offer selected products to DIN standards. Generally covering carbon steel and alloy steel fittings for higher pressures and temperatures and typically used in the oil, gas, chemical and heavy processing industries. Our customers tend to work predominantly with one standard or the other. For your convenience we have grouped most of the products accordingly. The detailed contents are shown on the opposite page.

4 GALVANISED MALLEABLE FITTINGS MATERIALS Blackheart Malleable Iron castings. DIMENSIONS generally to ASME B16.3 or JIS B2301, depending on manufacturing source. JIS B2301 dimensions are generally considered to be corresponding values to BS13 and BS56, although some sizes are not exact equivalents. THREADING is BSP pipe thread, to BS.21 (AS 1722, Part 1). The specification for BS 13 fittings is: Taper External (Series R) Taper Internal (Series RC) The specification for BS 56 fittings is Taper External (Series R) Parallel Internal (Series RP) Our stock fittings are usually BS 13 taper/taper, as this is believed to offer superior sealing characteristics due to greater thread contact (refer illustration below). Taper/taper threads are also being specified by increasing numbers of Gas Authorities, for the same reason. WORKING PRESSURES (except flanges) Recoended maximum working pressures are 1379 kpa for water and 103 kpa for steam, air, gas and oil. NOTE: Working pressures may also be limited by relevant Pressure Piping Codes or Industry regulations. UNEQUAL SIZES When ordering Reducing Sockets, Nipples, Bushes and Elbows, always state largest size first e.g. 0 x 0 bush. When ordering 3- or - way fittings, the sizing sequence illustrated below should be adopted BS 56 BS Parallel Threaded Fitting: Taper Threaded Pipe Taper Threaded Fitting: Taper Threaded Pipe = 32 x = 32 x ALTERNATIVE THREADING to special order. NPT (API linepipe threads) Taper Internal/Taper External can be supplied for fittings to American specification ANSI B16.3.

20 OLET FITTINGS WELDOLETS Used to make full size and reducing branch connections from 6 to 750 from run pipes 10 to 900 in order to: Facilitate header construction. Construct the joint to full pipe strength. Meet code design requirements for reinforced branch joints. Improve flow. Assure economical, clean and strong connections. Weldolet Thredolet THREDOLETS AND SOCKOLETS Used for making relatively small branch outlet connections. Threadolets and Sockolets are half couplings that are bevelled for convenience, tapered for strength, flared for fluid flow and drop forged for the ultimate in strength and ruggedness. Sockolet Elbolet ELBOLETS AND LATROLETS Used for making threaded, socket-weld or buttweld outlets tangentially to elbows or as 5 branch connections on straight pipe. The design provides for a full penetration weld. These fittings provide greatly improved flow conditions compared with 90 connections and are advantageous for many instrument connection applications. Latrolet INSTALLATION GUIDE Less fit up time is required for Olets than for most other fittings or fabricated connections.

26 FLANGES TO AMERICAN STANDARDS SPECIFICATIONS Forged Carbon, Alloy and Stainless Steel Flanges to American Standards are designed for use with pipes and fittings to American Standards, but can also be attached, in certain sizes to pipes made to British and Australian Standards. ANSI FLANGES SIZES CLASS, 300, 00, 600, 900, 0 & 2500 Dimensions shown are for Flanges made to the dimensional requirements of ASME B16.5 which is the accepted American Standard for all Flanges in sizes to 600 bore. SIZES ABOVE 600 Steel Flanges above 600 bore are made to various standards, as follows: CLASS, 300, 00, 600, 900 Dimensions to *MSS-SP or BS OneSteel stocks slip-on and weld-neck flanges to BS 3293 and blinds to MSS SP. *MSS-SP A Standard developed by the Manufacturers Standardisation Society (of the Valves and Fittings Industry) to provide uniform dimensions of flanges for use with high pressure pipelines larger than 600 diameter. These designs were predicated on flanges being used with API 5LX line-pipe of 52,000 lbs. minimum yield strength, and were proportioned accordingly. This Standard can be taken as being the extension of ASME B16.5 in sizes above 600 bore. API 605 gives dimensions for flanges above 600, which are different to MSS, BS and ASME. 26

27 FLANGES TO AMERICAN STANDARDS LARGE DIAMETER FLANGE STANDARDS ASME B16.1b This Standard establishes dimensions for Class 250 Cast Iron Flanges above 600, (as ASME B16.1 gives dimensions for large diameter Class 5 Cast Iron Flanges). API 605 American Petroleum Institute Standard intended primarily for use in Oil and Gas production. API 605 dimensions DO NOT match ASME, MSS or BS dimensions of similar pressure class. AWWA C7-5T This is a Standard published by the American Waterworks Association for steel Flanges to be used on waterworks and sewerage pipes. These flanges match Class 5 Cast Iron Flanges (ASME B16.1) in most dimensions. CLASSES 5LW, 175 & 350 These are Standards developed over the years by a number of manufacturers, not all using exactly the same dimensions. TEMA FLANGES The Tubular Exchangers Manufacturers Association (TEMA) lays down standards for dimensions and material specifications for Shell Flanges, Cover Flanges, Long Welding Necks for Nozzles and other heat exchanger components. BS.3293 This British Standard established dimensions for flanges for petroleum industry use, in Class, 300, 00 and 600, in sizes above 600, which correspond exactly to those of MSS SP- in Class 300, 00 and 600. Class 900 is not included in the British Standard, but dimensions are given for Class, which are similar to those of ASME B16.1, Class 5. BS.1560 This British Standard is based on ASME B16.5, and lists Steel Pipe Flanges to the same dimensions, pressure classes and in the same sizes as the American Standard up to 600. ANSI FLANGES MATERIAL SPECIFICATIONS American Standard Pipe Flanges are manufactured in a variety of Carbon, Alloy and Stainless Steels and selection of a particular grade is determined by the usual criteria of pressure/temperature requirements and corrosion resistance. Since these factors determine pipe and fittings to be used in a piping system, it is then necessary only to select flanges of a similar material. The classifications are used to group materials for Flanges Class through Class * lb and 300 lb classes only. ASTM Specifications directly covering forged flanges for these general materials specifications do not presently exist. Flanges of these materials shall be specified to conform to the nearest grade in A, except chemistry to conform to the ASTM specification listed. Intended primarily for use for subzero service. The ratings at -29 to 3 C given for the materials on page 2 shall also apply at lower temperatures.

29 FLANGES TO AMERICAN STANDARDS METHODS OF ATTACHMENT SLIP- ON FLANGES Although recoended practice in attaching Slip-On type flanges is to weld both at the flange hub and the pipe end, for mild service conditions only one is sometimes employed. In this case the weld is normally made at the pipe end. WELDING NECK FLANGES This type of flange is attached by buttwelding to the adjoining pipe or shell. The weld may be made either manually or automatically with or without a backing strip. Sound welds are readily obtained with any recognised welding procedure. THREADED FLANGES Threaded flanges are, of course, attached by screwing to threaded pipe ends. LAP JOINT FLANGES Lap joint flanges are most frequently used with lap joint stub ends, (Type A), although in some cases the lap is formed on the pipe end. Since they are free to rotate or swivel, there is no problem of bolt hole alignment. Such joints may be readily broken for inspection, cleaning, etc. The radius at the ID of the flange face accoodates that at the back of the lap, thus permitting more uniform application of loading. Lap Joint flanges find their most coon application when used with stainless steel stub ends. OneSteel stocks Type B stub ends which are used with normal slip-on weld flanges - ie Lap joint backing flanges are not required. SOCKET-WELD FLANGES In attaching socket-weld flanges, the pipe end is inserted into the socket and then welded at the flange hub. An inside weld at the pipe end is frequently made for greater strength or, with grinding, to provide a smooth bore without pockets or recesses. 29

31 FLANGES TO AMERICAN STANDARDS GASKET SURFACE Flanges, and other products designed for bolted connection, when furnished with raised face (or flat face) may have any type of gasket surface finish that is required. The more coon finishes are described in the following paragraphs. 1 STOCK FINISH: This is a continuous spiral groove. For nominal sizes 300 and smaller it is generated by a 1.5 radius roundnosed tool at a feed of 0.79 per revolution. For sizes above 300 the tool nose is radiused to 3.17 and the feed is 1.19 per revolution SPIRAL SERRATED: This too, is a continuous spiral groove, but it differs from the stock finish in that the groove is generated with a 90 included angle V tool. The groove is.39 deep and the feed is.79 for all sizes. NB OneSteel stocks flanges with surface finish in the range microns, ideal for use with both spiral-wound and ring gaskets. SMOOTH FINISH: This finish, which can be produced by several shapes of tools, shows no definite tool markings apparent to the naked eye. In the past this finish was sometimes known as Smooth Plane. This term however, should be avoided because of a tendency to confuse it with flat faced which, of course, applies to the flange facing and not to the gasket surface finish. 5 3 CONCENTRIC SERRATED: (Not illustrated) As the name suggests this surface finish is made up of concentric grooves. A 90 included angle V tool is used and the grooves are.39 deep and.79 apart. 5 COLD WATER FINISH: Produced by using a wide tool at high speeds, this finish is equivalent to that of a ground surface. It is mirror-like in appearance and surfaces finished in this manner are usually expected to be used without gaskets.

33 FLANGES TO AMERICAN STANDARDS ORIFICE FLANGES Orifice Flanges are used to locate an orifice plate in a pipeline and to provide a tapped opening upstream and downstream of the plate. The tapped openings are connected to pressure recording instruments and the pressure differential between the upstream and downstream readings is translated into a measurement of flow in the line. Orifice Flanges are always supplied in pairs or sets and are available with slip-on, weldneck or threaded connections. To facilitate the insertion and removal of orifice plates, the flanges are provided with a set of jacking screws. By backing off the flange bolts and tightening the jacking screws, the flanges are forced apart, allowing access to the orifice plate. Orifice flanges are available from all OneSteel branches. Orifice plates can also be supplied to customer requirements. Please contact your OneSteel Sales Office for further details.

The unique patented angle-pad design of Zero-Flex stainless steel or ductile couplings provides positive clamping of the pipe to resist torsional and flexural loads. FLEXIBILITY The Victaulic system accoodates expansion/contraction/ deflection and permits designing to take advantage of these characteristics. Elimination or reduction of special vibration accessories, expansion loops and settlement allowance are among the options. Contraction Deflection NOISE AND VIBRATION ATTENUATION The basic design of independent grooved pipes, sealed by a rubber gasket and unified by an externally bolted coupling housing, reduces noise/vibration transmission providing superior vibration attenuation throughout a system. SELF RESTRAINED JOIN The full engagement of the housing keys into grooves around the full pipe circumference provides significant pressure restraint and end load capabilities to withstand pipe movement from varied internal and external sources. End Load End Load EASY SYSTEM OR EQUIPMENT ACCESS Removal of two couplings (just four bolts) provides access for cleaning, maintenance, system expansion or changes. Victaulic butterfly valves provide dead end shut-off service to isolate equipment or systems. ALIGNMENT EASE The grooved system allows for rotation of pipe, valves, fitting or couplings before tightening for easy alignment. This compensates for some alignment errors and eliminates the two-holing required with flanges. Fitting in tight places is eased.

42 VICTAULIC SHOULDERED SYSTEM The VICTAULIC flexible coupling and piping system is simple in design. It consists of a self-sealing rubber gasket embracing two pipe ends and a coupling which encloses the gasket while engaging shoulders on the pipe ends. The VICTAULIC flexible coupling is leakproof under pressure or vacuum even when the pipeline is only partly full or under vibration. The small space occupied by the flexible coupling, the ease with which it can be fitted into confined spaces, together with the quick and easy coupling of pipe lengths make the VICTAULIC flexible coupling and piping system uniquely versatile. The system provides for limited expansion and contraction and accoodates some longitudinal and angular movement. OPERATING FEATURES SPEED AND EFFICIENCY VICTAULIC shouldered joints have two basic parts two shouldered ends on pipes (or fittings) and a complete coupling. EXPANSION AND CONTRACTION Every VICTAULIC joint in a straight pipeline allows for some contraction and expansion of the pipe length it connects. SYSTEM SIMPLICITY Just as VICTAULIC joints are easy to connect so they are easy to disconnect. The toggle coupling is hinged and requires no bolts. It has two components: a rubber ring the hinged coupling FLEXIBILITY The VICTAULIC system permits limited angular deflection in any direction without leakage so that uneven ground may be followed using straight pipes. Transmission of vibration from machines to pipelines can be minimised by using at least two adjacent VICTAULIC joints. Dismantle two VICTAULIC joints in a VICTAULIC line and any individual pipe length, fitting or valve requiring maintenance, cleaning or repair can be quickly removed or replaced. Adjoining sections are undisturbed; pipe ends and joints are unharmed. This feature also permits easy rotation of pipes. 2
