1 STAIESS STEEL EXPANSION JOINT, TYPE RFA-S A stainless steel expansion joint with carbon steel flanges for the use in thermal oil pipe systems. For applications where a thermal expansion of the piping has to be absorbe. This type of expansion joint is basically meant for axial movements only.

The pipeline, in which the expansion joint is mounte, must be fixe by fixe points which are strong enough to absorb the reaction forces prouce by: Our stanar axial expansion joints are to be installe with only one expansion joint between each fixe point. Pipeline systems where axial expansion joints are use must be protecte against sieways bening. By fitting guies, sieways bening is not possible.

The number of tie ros is epening on the iameter an pressure. Our stanar lateral expansion joints with tie ros are available in a esign with minimal two tie ros. No axial movements are allowe in the system. Type s LA3 an LA4 have flat iron hinges which are fitte through the flanges an wele on the outsie. A hinge which allows lateral movement is mounte on the fitting above the centre line of the bellows. Our stanar lateral expansion joints with hinges are available in a esign with ouble bellows. Common to both moels is the fact that tie ros an hinges alike have the task of absorbing the loas arising from the operating pressure. Hinges prevent axial expansions. This means that a lateral expansion joint can only move sieways (laterally) in one or more planes, making it possible for those movements which are perpenicular to the longituinal irection to be absorbe. Lateral expansion joints are therefore ieal for installation in pipe line systems with bens. Don t hesitate to ask AmniTec for further information.

5 STAIESS STEEL EXPANSION JOINT, TYPE AN Angular expansion joints from AmniTec are available in a variety of esign, type AN1 (with hinges) an AN (with gimbal). Type AN1 is esigne with flat iron fittings which are fitte through the flanges an wele on the outsie. A cylinric bolt, which allows angular movement in one plane, is mounte on the fitting above the centre line of the bellows. The expansion joint is mae with one bellows. Type AN is fitte with flat iron fittings. The fittings are secure to a mile ring with cylinrical bolts, which allow angular movement in all planes, above the centre line of the bellows. The expanion joint is mae with a single bellow. Common to both types is the fact that the fittings have the task of absorbing the loas arising from the operating pressure. The fittings make axial expansions impossible, which means that the expansion joint can onkly absorb bening forces. Angular expansion joints are suitable for installations where it is not possible to create stury fixing points, an in pipe systems where bening occurs. ANGULAR EXPANSION JOINTS FROM AMNITEC GUIDES Designe to absorb angular movements in all planes The hinges are esigne to absorb the reaction forces from the internal pressure which means that fixe points are not necessary Are not be expose to torsion Are available with flanges or weling ens Design pressure: for stanar type s: PN6, PN10, PN16 an PN5 Guies must secure that the pipeline is only moving in the preetermine irection All stainless steel expansion joints, type AN1 an AN, are custom mae an thus all materials an/or weling ens, floating/fixe flanges, plate flanges, weling neck flanges etc. are upon request.
