SECO can design and fabricate all sort of jacketed bellows. Jacketed bellows are used where regular insulation is not enough and when the main media going through the bellows needs to be kept at fix temperature. Jacketed bellows consists of two bellows, once inside and one...

An expansion bellow can be designed with reinforcement or equalizing rings which are normally located around the outside of the convolutions, preventing bellows forcing out under high pressure. The main purpose of these rings is to give support from the outside, so that bellows do...

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...

Double hinged bellows consists of two bellows joined together with a central pipe and dual hinge mechanism. These kinds of bellows are designed to absorb angular and lateral movements but again only in single plane. Double hinge bellows absorb pressure thrust of the system, hence...

Gimbal expansion bellows are designed to absorb angulation in any plane. The benefit of having these expansion joint is to absorb pressure thrust in the system, while still allowing angulation in multiple planes. These expansion joints are often used in pairs or with single hinge...

Universal tied bellows is a dual bellow but with an addition of tie rods. The tie rods are normally attached to the end of pipe or flanges with lugs that carry pressure thrust of the system. On top of this the tie bars also limit...

Universal un-restrained expansion joint consists of two bellows, connect by a central pipe either with flanges or pipe ends. This type of expansion joint can absorb greater amount of axial, lateral and angular movements. By increasing central length of pipe, greater movements can be achieved. These...

Hinged bellows are used where angular movements are required. Although hinged bellows angular movement is limited in one plane. These kinds of bellows are often used in sets of two or more to absorb large movements. Hinge bellows absorb pressure thrust of the system, hence...

Single unrestrained expansion joint consists of a single bellow, which is normally welded to a pipe, flange or with end fittings. This type of bellow can absorb small amount of axial, lateral as well as angulation movement. These expansion bellows do not restrain pressure thrust, hence...
