METALLIC EXPANSION JOINTS:

Dimensional changes in pipelines and equipment/vessels due to thermal expansion/contraction has become more acute in recent years as process temperatures and pressures have risen, plants have become larger and pipe work and other system more complex. EXPANSION JOINTS are now most recognized solution to the problem.

EXPANSION JOINTS are most highly stressed parts of a pipe work and need high care in convolutions design that combine safety, flexibility and yet cost effective. Convolution design is based upon pressure, temperature and movement. Years of experience has given us an opportunity to have designed a comprehensive range of bellows for a wide variety of applications, based on EJMA standards which are internationally accepted. Single ply or multiply, circular or rectangular, all are available in variety corresponding to applications.

The material used for the manufacture of these EXPANSION JOINTS is as follows:

ASTM-A 240 TP 304/304L
ASTM-A 240 TP 316/316L
ASTM-A 240 TP 321

The normal size range available is from 80 mm diameter to 1000 mm diameter. Smaller or larger can also be offered depending upon specifications and requirements.

End Fittings to customers furnished data or as per IS, BS, ASA & DIN Standards. Butt welded ends to weld directly with the piping.
