Sohail Engineering Corporation (SECO) can make thick wall or lens shape expansion joint in circular, rectangular, oval or any desired shape.

Thick wall expansion bellows are made from single thick ply usually starting from 4mm and above. These types of bellows are normally cost-effective solution for a large diameter pipe with low operating pressure. Large amount of movements can be absorbed by these bellows, by increasing the depth of the convolution.

SECO has a unique way of making this kind of bellows hence there is no restrictions on the nominal bore of the bellows.
