Metal bellows expansion joint,Bellows expansion joints, corrugated expansion joints, flange expansion joints, 304L, 316L
The axial inward pressure metal bellows expansion joint adopts the optimized design of the American EJMA standard.
The axial inward pressure bellows compensator is also commonly known as the shock-absorbing bellows compensator,
bellows, expansion joint, or expansion joint. It is composed of corrugated pipes (a type of elastic element) and accessories such as end pipes,
brackets, flanges, and conduits that make up its working body.
Axial inward pressure corrugated compensator belongs to a type of compensation component.
By utilizing the effective expansion and contraction deformation of its working body corrugated tube,
it can absorb the dimensional changes caused by thermal expansion and contraction of pipelines, conduits,
containers, etc., or compensate for the axial, lateral, and angular displacement of pipelines, conduits, containers,
etc. It can also be used for noise reduction and vibration reduction. Widely used in modern industry.
Axial inward pressure corrugated compensator, also known as expansion joint, expansion joint, or corrugated compensator.
Compensators are divided into several types: corrugated compensators, sleeve compensators, rotary compensators, square natural compensators,
etc. Among them, corrugated compensators are more commonly used, mainly to ensure the safe operation of pipelines, and have the following functions:
1. Compensate for axial, transverse, and angular thermal deformation of the absorption pipeline.
2. The expansion and contraction of the corrugated compensator facilitates the installation and disassembly of valve pipelines.
3. Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.
4. Absorb the deformation of pipelines caused by earthquakes and subsidence.
This expansion joint consists of a corrugated pipe and structure, mainly used to absorb axial displacement and minimal lateral and angular displacement.
It has a simple structure and low cost, and is also known as a universal compensator.
