dismantling jointshave a higher tensile and compressive strength, and it 's soft seal superior performance, easy handling and other functions , is widely used in metallurgy, electric power, chemical , water and sewage treatment and other industries , acting on the valve and pump the connection between the pipes .
1, can be axial displacement :
With axial compression or tension ; displacement volume, can eliminate the pipeline due to seasonal changes or through media ( such as hot water , steam ) produced by different thermal expansion and contraction stress . Protective equipment, valves , instrumentation and piping .
2, the circumferential displacement :
Expansion joints may be deflected in any direction to the surrounding dislocation pipe installation when solving different heart problems , prevention of damage to foundation settlement .
3 , easy installation and maintenance :
rubber expansion joints for pipe and pipe valves , meters and other connections , making removal extremely easy installation and maintenance . Avoid cutting welding and easily flare up of interference . Flange flexible rotation.
4 , safe and reliable :
Special design and manufacture of reinforced expansion joints and bolts plus a fixed limit .
Meanwhile, the dismantling jointproducts in the pipeline running to the displacement of more than a certain role in the operation of pipelines due to thermal expansion and contraction , crustal subsidence and forces have an important role in the expansion compensator . The product through the power transmission bolts can start the pump when the blind thrust transmitted to the pump and piping parts , avoiding the thrust focused on pipe or pump proximal corner , the occurrence of impact damage equipment, pipelines running plays telescopic compensation displacements
