WHAT IS EXPANSION JOINT ?

Expansion Joint is a product that maintains the piping system and protects equipment by absorbing high stress magnitude on pipes due to outer temperatures that may influence energy delivering pipes, pipe expansion or contraction caused by temperature changes in fluids, equipment vibration problems or seismic motions.

Ayvaz designs and manufactures bellows expansion joints from the simplest standard expansion joints to highly complex expansion joints which are designed especially on the basis of individual customer requirements. Metal expansion joints are single or multi-layered stainless steel expansion joints with a high level of expansion absorption and a low spring rate.

Ayvaz, metal bellows are designed according to EJMA coding (10th edition) EJMA rules apply to single or multiple layer bellows expansion joints, unreinforced, reinforced or toroidal, subject to internal or external pressure and cyclic displacement.

The bellows shall consist of single or multiple identically formed convolutions. The suitability of an expansion joint for the specified design pressure, temperature, and axial displacement shall be determined by the methods described in EJMA. Construction of metal expansion joints is completed according to EN14917:2012 European standard and in compliance with PED 2014/68/EU requirements.

Apart from European standards, Ayvaz also deals with the design and production of metal expansion joints according to ASME standards, Section VIII div 1& div 2 (U stamp, U2 stamp).
