Double flange expansion joint (also known as expansion joint, compensator) is a key compensation element in the pipeline system. Flange expansion joint is a pipeline connector used to connect two sections of pipelines with different displacements, different pressures, different diameters or different materials. It is a device that compensates for the change in pipeline length and absorbs the stress caused by temperature changes in the pipeline through the expansion and contraction function.

1. Working principle of expansion joint

The expansion joint adopts a expansion mechanism, which adapts to the deformation of the pipeline through the expansion and contraction function of the expansion mechanism to achieve the purpose of keeping the entire pipeline system running smoothly. It can reduce the stress caused by external factors such as temperature changes, pressure changes or earthquakes in the pipeline. It is mainly used to absorb the deformation of the pipeline caused by temperature changes, vibrations or displacements to ensure the safe operation of the system.

2. Classification of double flange expansion compensators

According to different needs and use environments, expansion joints can be divided into metal expansion joints, rubber expansion joints and fiber expansion joints. Among them, carbon steel pipeline expansion buckle pipe fittings, as a metal expansion joint, have high strength and durability.

3. Characteristics of carbon steel pipeline expansion buckle pipe fittings

Carbon steel pipeline expansion buckle pipe fittings have the characteristics of good pressure resistance, corrosion resistance and easy installation. It can effectively connect and separate pipeline systems, prevent leakage and breakage, and adapt to the expansion and contraction of pipelines.
