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.

Vertical motion is minimal. We have developed a unique product to handle this seismic motion. Our Vee construction is based on two 30, 60, 90 triangles complimenting one another to form a 60 degree ‘Vee’ at the bottom. We thought the concept so interesting that we tooled up for these fittings rather than use the common 45, 90 and 180 degree configurations.

Since it may be necessary to fit these Vee’s at odd angles, depending on space conditions, we have floating ASA 150 carbon steel flanges on both ends. No competitive products can be rotated this way.

Vee’s are often used in simple expansion applications as well.

Other fittings include Carbon Steel NPT Nipples, Weld Ends, Copper Female Sweat Couplings or Grooved Ends, as required. All of our Vee assemblies are designed for +/- 100mm movement in all directions. Other manufacturers offer +/- 50mm designs as well to reduce cost, but it is not worth the risk of misapplication.

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.

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.

ECMN Expansion Compensator

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

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.

Adjustable Sliding Guides

Mason Adjustable Sliding Guides (ASG) are pipe guides that can be installed in any orientation. They come is a range of standard sizes to suit pipes from 20mm to 300mm in diameter. Larger Guides are available on request. Full details can be found in the attached bulletin below.
