RUBBER BELLOWS general

1 RUBBER BELLOWS general Our rubber compensators are made from various elastomers and provide the flexible element in pipework that is indispensable in todays technically advanced plant and machinery installations. By using the best quality proven rubber compounds and a construction based on many years of experience, our rubber compensators are produced to a high quality standard to guarantee maximum safety and performance. The rubber compensators provide: - ompensation of thermal or mechanical movement of pipework in axial, lateral or angular directions. - Absorption and isolation of vibration combined with damping of pipework borne sound transmission. - Reduction of pressure pulses in pipework. - Flexible joint faces which provide built-in sealing within the compensator construction (see installation instruction). - ompensation for pipework misalignment on flexibly mounted installations. Our rubber compensators are available in 5 standard constructions, type 1 A, type 1 S, SB, 3K / 3K2 and 4K each available in different rubber qualities, so that the correct rubber compensator can be selected for every kind of medium and temperature. Next to that the high pressure compensators are available.

2 TEHNIAL DATA AND DIMENSIONS compensator type 1A The standard expansion joints type 1A combine high flexibility with a short overall length. Pressure rating 16 bar (10 bar * ) working pressure, a test pressure of 25 bar (16 bar * ) and a burst pressure of over 60 bar (30 bar* ) guaranteed. ( * For compensators larger than NB 200). The permissible working pressure is determined by the bellows, also a higher temperature of the medium and the type of flanges used have an influence. The special flow-assisting convoluted shape of the bellow minimises detrimental turbulance of the medium and pressure loss. High tensile strength textile cord plies combined with proven syntethic rubber mixes guarantee maximum reliability and an extended working life. The standard units are supplied ready for installation with rotatable galvanised steel flanges to DIN ND 10 at each end. Other drillings ND 6 and ND 16 etc. are available as alternative flange materials. ARTILE ODE * OMPENSATOR ALLOWABLE EFFETIVE WEIGHT MIN. MAX.

9 TYPE 3K / 3K2 general specification As an addition to the flanged compensator range, the 3K and 3K2 rubber expansion joints have been designed especially to provide small, low weight expansion joints which are both very flexible and simple to install. The 3K ranges accommodate misalignment, axial and lateral pipework movements and dramatically reduce the transmission of noise, vibration and shock. The expansion joints marked with a yellow ring are manufactured in black nitrile rubber, reinforced with synthetic fabric to achieve a high mechanical strength. They are suitable for use with cooling water, fuel and lubrication oil pipework systems up to 90. The red ring marked expansion joints are manufactured in black EPDM rubber reinforced with Aramide fabric to achieve high strength at elevated temperatures. They are suitable for use with hot (cooling) water installations up to 130. The burst pressure safety factor is 5 times the working pressure of 4 bar. The minimum workpressure (absolute) is 70 kpa and can be lowered by fitting a vacuum support ring. The working pressures are guaranteed by using the recommended powerclamps according to the table. Both executions have been type approved by Germanischer Lloyd.

12 TYPE 4K general specification As an addition to the 3K compensator range, the 4K multiple bellow expansion joints with support rings have been designed especially to provide small, low weight expansion joints which combine flexibility and high medium temperature with simple installation. The expansion joints are manufactured in brown synthetic rubber, with a black inner liner, reinforced with synthetic fabric to achieve a high mechanical strength. They are suitable for use with cooling water, fuel and lubrication oil pipework systems up to 220. The 4K ranges accommodate misalignment, axial and lateral pipework movements and reduce the transmission of noise, vibration and shock. The burst pressure safety factor is 3 times the working pressure of 4 bar. The minimum workpressure (absolute) is 80 to 90 kpa, depending on compensator size and can be lowered by fitting vacuum support rings.
