1 Steel compensators General description of steel compensators 1 STENFLEX steel compensators have served with distinction for more than forty years. They are the preferred flexible pipe connection elements of choice in manufactured appliances, machinery, apparatus and piping engineering. Constant further development and innovations update our product range to meet the needs of current and changing markets, and fulfil the requirements of industry in regard to: Operating safety Reliability Pressure and temperature resistance Vacuum stability Flexibility Impermeability Corrosion resistance No maintenance Long service life The large-scale industrial manufacture of steel bellows, constant control of compliance with all manufacturing, business and quality processes in line with EN ISO 9001 and decades of experience in the development and manufacture of steel compensators: all this guarantees a uniform product of the highest standard. It underlines the STENFLEX Quality Claim. Our expertise in compensator engineering is reflected in the long service life and consequently in the high operational reliability of our steel compensators, thanks to the excellent production functionality and quality. For decades our steel compensators have been used in a wide variety of applications, and guarantee troublefree operation on-site. STENFLEX has been assessed and approved as manufacturer of steel compensators, on the basis of AD norms and international standards. Calculations are based among other factors, on AD 2000-B13, EJMA and STOOMWEZEN. STENFLEX steel compensators have been certified by numerous classification, and acceptance societies, and bear the CE mark. Our engineers together with our R&D department are always available for technical consultation, and ready to help in solving specific application problems at any time. Purpose Steel compensators are used in appliances, machines, apparatus and pipe systems where space is restricted to compensate for to compensate for expansion to reduce tension to absorb noise and oscillation transmission to compensate for ground and foundation settlement as adapters to compensate for installation inaccuracies as dismantling pieces for fittings Steel compensators are flexible pipe connection elements and are used in a variety of industrial applications: Machine engineering Domestic industry Chemical industry Process plant engineering Gas and water supply Exhaust technology

2 Development/Design s STENFLEX steel compensators vary according to the following criteria: type (universal/lateral/angular compensators) pipe connection type (flange, welding end or threaded connection) material quality of the bellows (rated to the media transported in the pipes) STENFLEX steel compensators are rated theoretically using state-of-theart computing techniques (which include the Finite Element Method). They are optimized under experimental conditions. National and international calculation standards are used to rate the bellows. Our development engineers use the most up-to-date development tools throughout the development stage to validate the construction process in terms of form, function and installation. Hence we can offer our customers the following advantages: bellows structure (rated to the, pressure and temperature load) Our compensators are delivered ready for installation. STENFLEX manufactures compensators in noal widths and for noal pressure rates PN 1 - PN 25. A wide range of materials is used, with temperature resistance from 19 C to +900 C. Design and development in line with the specific requirements, resulting in safe and extremely durable compensators Efficient products by incorporating superior functionality Structures that are easy to install Reduced lead times for special designs Together with the standard and basic versions featured in the catalogue, special versions can also be developed and produced on request, for special operating conditions or special structures. Connection parts (that deviate from DIN) such as ISO, ANSI, VG, SAE standards etc. are also available. compensators Structure: Steel bellows with connection parts (flange, welding end or threaded connection). Movement absorption: shift, and slight all-round of the compensator is possible. compensators with two bellows are used to absorb larger. Fixed points: Robust pipe fixed points and correct pipe routing are necessary to absorb the axial forces. Lateral compensators Structure: Steel bellows with laterally movable restraints and flanges or welding ends. Movement absorption: Lateral shift of the compensator is possible. The restraint absorbs axial reaction force and relieves the pressure on the pipe's fixed points. Lateral compensators, with two bellows and a connecting pipe are used to absorb large. Fixed points: Only light fixed points are required to absorb lateral and friction force. Angular compensators Structure: Steel bellows with hinge restraint and flanges or welding ends. The rotating axis of the hinge restraint is in the middle of the bellows. Movement absorption: Angular of the compensator is possible. The angular joints regulate a defined angular, absorb axial reaction force and relieve the pressure on the pipe's fixed points. We differentiate between angular compensators with a hinge (bellows angular guided on one plane) and angular compensators with a cardan hinge restraint (bellows guided on two planes). Fixed points: Only light fixed points are required to absorb angular force and friction force. 2

3 Steel compensators General description of steel compensators Steel bellows Structure STENFLEX steel bellows are available in a variety of structures and versions. The steel bellows is the flexible element of every compensator. It must fulfil the requirement for good movability with simultaneous pressure resistance. Variable parameters (wall thickness, number of plies, convolution geometry, number of convolutions) detere the pressure resistance, absorption and spring rate (selfresisting force) of the bellows. Oneply, two-ply and multi-ply bellows are manufactured from various materials with different wall thicknesses. Our calculation methods ascertain the stability limits. The ability to withstand buckling is the prime criterion for smaller bellows diameters, whereas in larger bellows diameters it is convolution stability. Material qualities STENFLEX compensator bellows are manufactured from top quality sheet metal. Different material qualities are used to cover the many operating conditions in various industrial applications. one-ply two-ply multi-ply Multi-ply bellows are to be used for vibration load Buckling instability of a steel compensator The outstanding characteristic of the steels and alloys is their particular resistance to chemically aggressive liquid media.

4 Rating, service life Steel bellows, as a rule, are rated for a temperature of +20 C, the noal pressure and a load of 00 load cycles. One load cycle refers to the procedure beginning at zero position, from where the compensator moves to the maximum elongation (positive) position, back through the zero position to the maximum compression (negative) position, and back to the zero position. Together with the tolerable operating conditions pressure temperature number of load cycles Connection parts STENFLEX steel compensators are supplied ready for installation. They are connected to pipes, fittings, pumps, the following parameters can also influence the service life of compensators: corrosion high-frequency oscillations sympathetic vibration pressure shocks temperature shocks incorrect installation Corrosion can be caused by incorrect selection or combination of materials, conveyance of aggressive media and inappropriate cleaning with chemical agents. High-frequency oscillations and sympathetic vibration must be avoided by all means, because this will result in fatigue failure/fracture. tanks etc. by flanges, welding ends or threaded connections. The connections are standardized to fit coer- Pressure and temperature shocks must be avoided. It is important not to exceed the permitted maximum values. Incorrect installation can be prevented by compliance with our installation and assembly instructions. In the case of unrestrained compensators, the absence of fixed points can cause the pipeline to shift. This usually destroys the compensator. cially available flanges, threads and pipes. s STENFLEX steel compensators, series SF, are supplied with rotating flanges or fixed flanges. Standard flanges are drilled in accordance to DIN Standard screws can be used because the flanges are drilled for through bolts. Other flange connections are possible, e.g. to DIN, ANSI, BS, VG, SAE, for exhaust pipes and ventilation systems. s for lateral compensators are equipped with ears for tie rod restraints. The design differs between flanges with welded ears and oval flanges, depending on compensator type and size. Angular compensators are equipped with oval flanges and welded hinge restraints. s of unalloyed steel are electrogalvanized or given an anti-corrosion prime coating. Stainless steel is used to meet tougher corrosion protection requirements.

6 Restraints Restraints are used for lateral and angular compensators. The restraints absorb axial reaction force produced by inner pressure. Even so, the connected pipe must be equipped with light fixed points to absorb moving force and moments. Precise rating details and operating parameters of the corresponding machinery or equipment must be known to correctly calculate the degree of restraint needed. Standard restraints are available for the lateral and angular compensator program. They are calculat- ed on the basis of the material strength values at +20 C. Reduced strength values at higher temperatures are taken into account. Tie rod restraints Lateral compensators are equipped with adapters for tie rod restraints. The design differs between flanges with welded ears or oval flanges depending on the compensator type and size. Tie rod restraints run flexibly on sperical washers and conical seats. corrosion protection (special varnish, special coating, etc.), can be supplied on request. The tie rods, spherical washers, conical seats, and nuts are electrogalvanized. Ears of unalloyed steel are given an anti-corrosion prime coating.

As a rule they are made of stainless steel. Internal guide sleeves are required to handle higher flow speeds (see diagram) and the resulting possible resonance in the bellows. Also to deal with turbulence as a result of deflection in the direction of flow (e.g. behind pumps, valves, T-pieces, pipe bends). Even under these conditions, the internal guide sleeve is intended to guide the medium turbulence free through the convoluted bellows. An internal guide sleeve also provides the bellows with reliable protection from abrasion by the medium. In this case the internal guide sleeve must have thicker walls. 7 Flat seal Pipe flange Compensator flange Internal guide sleeve with flared flange Flow rate (m/s) Gases Liquid media Direction of flow Noal diameteter () Internal guide sleeve with flared flange Internal guide sleeves have proven successful as protection for the bellows at flow rates above the curve. The data are of indicative nature.

8 compensators are equipped with cylindrical internal guide sleeves and lateral compensators with conical internal guide sleeves. compensators with internal guide sleeve and flared flange require an additional seal between the bellows flare and the flared flange. In conical internal guide sleeves the tapered cross-section must be taken into account (pressure loss and flow rates). Telescopic internal guide sleeves with a narrow gap are used where the medium is able to flow through the compensator in both directions. Attention must be paid to the direction of flow to ensure that compensators with internal guide sleeve function properly. The direction of flow is indicated by the arrow marked on the compensator. compensator with cylindrical internal guide sleeve compensator with telescopic internal guide sleeve Lateral compensator with conical internal guide sleeve Guide sleeves Guide sleeves stabilize the compensator in its axial and prevent it from buckling. As a rule, guide sleeves are made of thick-walled, stainless or unalloyed steel. compensators with two bellows are provided with guide sleeves in the factory, as a rule with a telescopic design. Compensator guide sleeves do not supersede pipe guide bearings. Direction of flow compensator with telescopic guide sleeve Protective covers Protective covers are used to protect the bellows from damage during installation and operation. The pipes, fitted to the outside, protect the bellows reliably from splashes of welding materials or other mechanical influence. As a rule protective covers are made of stainless or unalloyed steel and can be fitted on the outside both over the flanges and between the flanges. 8 Compensator with removable protective cover on the outside over the flanges Compensator with telescopic protective cover between the flanges
