PEX Expansion Fittings Performance Introduction

　　PEX expansion fittings are also called compensators or expanders habitually. It is composed of metal bellows (a kind of elastic element) and notes of end pipes, support frames, flanges, ducts, etc., which constitute the main body of its work. PEX expansion fittings are a flexible structure set on the container shell or pipeline in order to compensate for the additional stress caused by the temperature difference and damping vibration. Use the reasonable telescopic deformation of the main metal bellows in its work to digest and absorb the specification changes caused by thermal expansion and contraction of pipes, ducts, containers, etc., or to compensate for the radial and horizontal displacement of pipes, ducts, and containers. And angular offset. It can also be used to reduce noise and shock. For heating, in order to avoid pipe deformation or damage due to thermal expansion or temperature stress when heating pipes are raising the temperature, a compensator is set on the pipe to compensate for the thermal expansion of the pipe, thereby reducing the stress of the wall thickness and the effect in various The interaction force on the structure of the valve or support frame.

　　Because PEX expansion fittings, as a kind of ductility compensation component that can be retracted at will, have the advantages of reliable work, excellent characteristics, and compact structure, and have been widely used in chemical plants, metallurgical industry, nuclear power generation, and other units. The PEX expansion fittings used on the container come in various forms. In terms of wave patterns, U-shaped PEX expansion fittings are commonly used, followed by Ω-shaped and C-shaped. In terms of structural compensation, the PEX expansion fittings selected on the pipeline are divided into all-round type, working pressure balanced type, door hinge type, and universal joint type.
