MEET OUR SPECIAL EXPANSION JOINTS
Bellows of special expansion joints are designed according to EJMA code. For high pressure applications multi layered bellows also bellows with reinforcing and equalizing rings are possible.
According to the requested features like type of transported media, spring rate values (axial, lateral, angular) and operation temperature and pressure also life cycle bellows material could be customized.
CONSTRUCTION
Expansion Joints are the parts of piping system of pressurized equipment. In this respect construction of the expansion joints are designed and produced according to European pressurized equipment directive (PED 2014/68/EU) as well as American National Standard for piping process ASME Section VIII Div. 1&2, ASME B 31.3.
All components of the expansion joints like, pipes, caps, flanges, tie rods etc… are checked by piping stress analysis thus enable us to select material type & thickness according to permissible stress values.
