An expansion bend is a bend, which is inserted in a pipe run to provide for the expansion of the pipe resulting from a temperature change. It is used where the pipe direction must change at 90° or allowance for thermal expansion is required. It is designed to take up to 20mm of thermal expansion.
Expansion Compensators are designed for installations where the principal movement is axial. These compensators are completely enclosed and externally pressurized, which prevents damage to the bellows and eliminates pressure instability. Expansion compensators are generally used to absorb pipe motion in small diameter systems. They provide the inherent performance benefits and safety features of the externally pressurized expansion joint design in a compact package. Expansion compensators are designed for an operating pressure up to 16 bar and in the low pressure range up to 50 mbar.
Expansion Engine is a vertical, single acting, reciprocating type of engine. This produces the cold required for the plant. The expansion engine consists of three major units such as drive unit, cylinder unit for air expansion and hydraulic system for operating the valves. The expansion engine has an extended crankshaft enabling the accommodation of the cam box.
