Rubber Expansion Joints

Rubber expansion joints, also known as flexible rubber expansion joints, vibration dampers, pipeline vibration dampers, and shock absorbers, are a type of pipeline expansion joint with high elasticity, high airtightness, and resistance to various media and weathering.

Stainless Steel Rubber Expansion Joint

Flexible Compensation: Rubber elasticity absorbs axial ±10–20mm, lateral ±5–15mm, and angular ≤12° displacement, adapting to thermal expansion and contraction/installation deviations.

Double-Sphere Rubber Expansion Joint

The double-sphere rubber expansion joint, also known as a double-sphere vibration isolator, is made of two rubber spheres vulcanized into one piece. It has a longer expansion length and its vibration damping effect far exceeds that of a single-sphere rubber expansion joint. It is a specialized accessory for pipelines with high vibration and large displacement.

Large-Flanged Rubber Expansion Joints

Large-flange rubber expansion joints are an improved version of ordinary rubber expansion joints designed to prevent pull-out. The core features are an extra-large flange at both ends of the rubber sphere (fully covering the flange face) + a metal slip-on flange.

Threaded Rubber Expansion Joints

High internal density, able to withstand high pressure, and excellent elastic deformation. Reduces vibration, lowers noise, has good extensibility, and is easy to use.

Concentric Reducing Rubber Expansion Joint

The concentric reducing rubber expansion joint, also called a reducing rubber expansion joint or a reducing rubber expansion joint, has two ends with different diameters, but their centers are on a straight line.
