Rubber expansion joint is Hesper’s main product, belong to our expansion joint part. It is a Flexible connector widely used in pipeline systems. Its structural characteristics directly determine its performance advantages and application range. Rubber expansion joint is mainly composed of inner rubber layer, reinforcement layer, outer rubber layer and flange or metal frame and other components. The design and material selection of each part are carefully considered to ensure its reliability and durability under complex working conditions.

Dismantling Joints are one main kind of our expansion joints, play very important role in pipeline connection, they can expand and contract axially within a certain range to absorb the displacement of the pipeline,which caused by thermal expansion and contraction or other factors, thereby protecting the pipeline system from stress and damage.

Sand suction rubber hose is a kind of our wear resistant rubber hoses, which is widely used to absorb impurities such as silt, sand and gravel. Sand suction rubber hose named according to its usage, due to its wide range of applications, such as river dredging, mining, construction engineering, etc., the sand suction rubber hose plays an important role in all many industries.

When the rubber expansion joint is susceptible to large stretching, vibration, torsion or lateral movement during use, sometimes it is necessary to add limiters(tie rods) to ensure the normal operation of the joint to extend its service life.

As a pipe connection device, the bellows expansion joint can reduce vibration and noise in the pipe system, and can absorb the thermal expansion and contraction which caused by temperature changes and other factors. However, in some special cases, the metal expansion joint needs to be used together with the inner sleeve to achieve better results.
