METALLIC EXPANSION JOINTS AND COMPENSATORS

METALLIC EXPANSION JOINTS AND BELLOWS

Metal expansion joints (also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. Expansion joints have usage in various sectors, like energy production, paper industry, chemical industry, water treatment, oil and gas. Expansion joints can be used wherever thermal movements or vibration occurs in pipelines.

Metallic Expansion Joints are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces.

There is a wide range of metallic bellows designs in a variety of materials. Options range from the simplest convoluted bellows used in petroleum refineries.

Materials include all types of stainless steels and high grade nickel alloy steels.

Any pipe connecting two points is subjected to numerous types of action which result in stresses on the pipe. Some of the causes of these stresses are:

Internal or external pressure at working temperature
Weight of the pipe it self and the parts supported on it
Movement imposed on pipe sections by external restraints
Thermal expansion
