What is the pipe expansion joint?

The pipe compensator is also called a pipe expansion joint or metal expansion joint.


It is composed of bellows (a kind of elastic element) and accessories such as end pipes, brackets, flanges, and conduits that constitute the main body of the work.

Belongs to a compensation component. Utilize the effective expansion and contraction of the bellows of its working body to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, conduits, containers, etc., or to compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used to reduce noise and vibration.


It is widely used in the modern industry. In terms of heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heating up, it is necessary to install a compensator on the pipe to compensate for the thermal elongation of the pipe, thereby reducing the stress and stress on the pipe wall.


The force acting on the valve or support structure.


Features:



1. Compensate the axial, lateral and angular cold and heat deformation of the absorption pipeline;

2. The expansion and contraction of the corrugated compensator is convenient for the installation and disassembly of the valve pipeline;

3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline;

4. Absorb the deformation of the pipeline caused by earthquake and ground subsidence.



The billet used to produce steel pipes is called a billet. Usually, high-quality (or alloy) solid round steel is used as the tube billet. Some tube production methods also use steel ingots, continuous casting billets, forging billets, rolled billets, and centrifugal cast hollow billets to make tube billets.



In general, the tube blank refers to the round tube blank. The size of the round tube billet is represented by the diameter of the solid round steel.
