Expansion Joint Components Introduction: How Many Do You Know?

Expansion Joint: The expansion joint of an expansion pipe consists of two metal bellows (inner and outer) and a flange. It connects the two ends of the pipeline and can withstand the expansion and contraction of the pipeline. Different materials and bellows shapes are available for the expansion joint, allowing selection of appropriate joints based on the operating environment and media.

Flange: The flange is a crucial component connecting the expansion pipe to the pipeline. It typically consists of two semi-circular flanges, bolts, gaskets, etc. The material and type of the flange are also selected based on the operating environment and media.

Sealing Ring: The sealing ring is an important sealing component at the connection of the expansion pipe, used to prevent media leakage. Different materials of sealing rings can be selected depending on the media and operating environment, such as rubber sealing rings and PTFE sealing rings.

Support Components: Support components are an important part of the expansion pipe, used to support the weight of the expansion pipe and ensure pipeline stability. There are many types of support components, such as hangers and supports.

Joint: The joint is the connecting component of the expansion pipe, with different connection methods such as internal threads, external threads, butt joints, and flanges. Different joint types with different connection methods can be selected based on the operating environment and media.

Protective Sleeve: The protective sleeve is the outer protective layer of the telescopic pipe, protecting it from external damage and corrosion. Protective sleeves are available in different materials, such as stainless steel, aluminum alloy, and plastic.
