Expansion Joints are designed for tough, demanding industrial applications, as found in: chemical/petrochemical plants, industrial process piping systems, marine services, power generation plants, steel mills, water/wastewater and pollution control systems. Installed next to mechanical equipment or between the anchor points of a piping system an expansion joint will: absorb pipe movement/stress, reduce system noise, isolate mechanical vibration, compensate alignment/offset, eliminate electrolysis, and protect against start-up surge forces.

When selecting an expansion joint, these important factors should be considered:

Pipe or line size Maximum working pressure Maximum Temperature Type of movement (axial, lateral, angular, or a combination of movements) Amount of movement Rate of media flow or velocity through the expansion joint

Type of media flowing through the expansion joint (steam, water, corrosives, etc.) Type of end fittings (flanges, weld ends, or special fittings.) Extreme service conditions (vibration, large amounts of motion in more then one plane, etc.)
