MPW design and manufacture Expansion joints in a wide range of sizes and materials to suit all applications. They consist of flexible mechanical elements, mainly of one or more metal membraines formed into bellows connected with flanges, weld ends or threaded fittings. They can be supplied with inner sleeves, external protective sleeves, anchor supports and ties etc.

The primary applications of expansion joints are in piping systems to compensate for expansion and shrinkage due to temperature changes, to compensate for mis-alignment, to make pipe assembly easier and to dampen vibration and noise among many other uses.
