Expansion Joints

Many expansion joints are custom manufactured to diameters as large as 8 feet (2.4m). The construction varies, depending on the operating pressure and the required movements.

We can provide these unusual constructions in virtually every configuration. We can build to your specific product description or complete our own recommendations based on your movement and pressure requirements. 

There is a strong demand for stainless expansion joints in 2” (50mm) thru 16” (400mm) diameter with 2” (50mm) axial and 1/4” (6.4mm) transverse capability. Weld ends are most common, but there are also flanged requirements. All our flanged joints have one floating flange to facilitate installation and eliminate torsional stress. The other is raised face.

EFL – Bellows Expansion Joint with Fixed and Floating Flanges

These products are typically supplied in 304 stainless steel, with ASA-150 carbon steel plate floating and fixed raised face flanges. Other flange drillings can be made available on request. Available in 50 psi and 250psi maximum full vacuum pressure ratings. Optional control rods are also available.

EW – Bellows Expansion Joint with Weld Ends

Typically supplied in 304 stainless steel with carbon steel schedule 40 bevelled weld ends. Available in 50 psi and 250psi maximum full vacuum pressure ratings.

Braided Annular Flexible Hose

Mason UK can provide a range of stainless steel braided annular flexible hose. These flexible pipe connectors are suitable for use with corrosive fluids, gases or temperatures and pressures outside of the rubber range.

Vee Assemblies

Many buildings are separated by expansion joints through the walls and floors. During an earthquake the two adjacent parts resonate with relatve motion of as much as +/- 100mm in shear as well as toward and away from one another.

Bellows Pump Connectors

All bellows differ from stainless steel hose in the corrugation configurations. Bellows are deeper and wider and they are made from a heavier material to handle the pressure without the braid. A very common location of our 2 ply bellows is at the pumps.

Expansion Compensators

Expansion Compensators are essentially a bellows that is protected by and guided within a pipe housing, and designed to give improved stability.

Housed Expansion Joints

Expansion Compensators and Housed Expansion Joints are essentially a bellows that is protected by and guided within a pipe housing.

Stainless Steel Flexible Pipe Connectors

Stainless steel connectors are used where movement is required between two pipes or pieces of equipment. They are mainly required when pipes have to bridge building expansion joints or to allow for movement of mechanical equipment.
