Universal Angle Expansion Joint
Universal angle expansion joints have a universal ring, circumferential two pairs of mutually perpendicular hinge structure, can be more than one direction of displacement and deformation, and can withstand a certain amount of internal pressure thrust, suitable for complex pipe system and need to change the direction of the part of the frequent.
Overview
Components:
Bellows: responsible for deformation to absorb displacement. Usually made of stainless steel 304, 316L, 321 and other materials.
Universal ring: capable of absorbing angular displacement in any plane.
Hinge plate: helps to absorb angular displacement.
Flanges and receivers: usually made of carbon steel, stainless steel 304, 316L, 321 and other materials.
Tie rod bolts and nuts: usually made of carbon steel.
Features:
Small volume and light weight: universal angular expansion joints are compact in design and light in weight, easy to install and maintain.
Large compensation capacity: through the combination of two or three pieces, it can compensate for large angular displacement.
Wide range of working conditions: applicable to different working pressures, temperatures and media conditions, such as 0.25MPa to 2.5MPa working pressure, -50℃ to 420℃ working temperature, applicable to liquids, gases and other media.
