Structural composition

Single flange limit expansion joint is mainly composed of body, expansion pipe, gland, sealing device and limit device.

Body: Usually made of high quality carbon steel or stainless steel, with high strength and corrosion resistance.

Expansion pipe: rubber or bellows and other flexible materials, with good expansion and sealing.

Gland: It is used to fix the expansion pipe and is tightly connected with the body through bolts.

Seal ring: adopts advanced sealing technology to ensure that the joint does not leak during expansion and contraction.

Limit device is used to limit the expansion range of the expansion pipe to prevent damage to the joint due to excessive expansion.

Advantages

High pressure tolerance: able to withstand high pressure.

Large displacement compensation: able to absorb and release the deformation and displacement energy of piping system.

Easy installation: simple structure, easy installation and maintenance.

Good sealing performance: adopting advanced sealing technology to ensure no leakage.

Wide range of application: applicable to a variety of complex engineering environments and media conditions, such as water supply, drainage, HVAC, fire fighting, chemical industry and other fields.
