Expansion Compensators
Expansion Compensators are essentially a bellows that is protected by and guided within a pipe housing, and designed to give improved stability.
Bellows are externally pressurized. 3.5 Minimum Safety Factor for both Bellows and Housing. They are available with threaded nipple ends (ECMN), floating flanges (ECFFL), copper sweat ends (ECCPS) and weld end grooved nipples (ECWGN).
Mason Improvements
• Good operating clearances to prevent binding.
• A much better looking mechanism that can be used to partially compress joints prior to installation to allow for contraction as well as expansion on installations with temperatures below ambient when in service. The locking device is a permanent part of the construction. They can always be tightened to hold the expansion joint in a particular position for removal while piping is serviced.
• A depth gauge on the moving end to monitor movements, make certain that joints are at the 0 position before installation, or used to pre-set joints in some preferred position.
• Great attention to canister and pipe welding details.
• Internal and external clearances to prevent bellows wear because of rubbing.
• Safety factors between 3.5 and 4 compared to others at 2.25. Double drains on most designs, generous lifting near the centre of gravity for easier handling.
• A raised face flange and a floating flange on all flanged products for easier installation and bellows anti-torquing protection.
• Grooved fittings are beveled as well to allow welding into pipe lines as an alternate method. (Mason does not recommend welding.)

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 Joints
Many expansion joints are custom manufactured to diameters as large as 8 feet (2.4m). We can build to your specific product description or complete our own recommendations based on your movement and pressure requirements.
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.
