Insulating joints for pipeline 

Any pigging products inquiry or questions, pls dont hesitate to contact us

The insulation ring of rigid insulation joint is made of  high
resit compression (not less than**0N/mm2), low water absorption, high electrical insulating and anti-aging materials. Insulation resistance  value is more than *0MΩand it is
far greater than other insulation joint resistance,hence,its greatly improve the insulation  and  reduce the leakage current. In addition,as the sleeve (assembly) is annular space. It is
injected polymer composite and resin with low viscosity  to make it has certain compression strength. it can give full play to the cathode protection and improve the operation of the protected pipe life

Rigid insulation joint formed a rigid cylinder that far greater than pipeline bending section coefficient Cause it can bear larger bending moment (According to the same strength of pipeline design),It eliminates the leakage accident casued by unreasonable structure with insufficient stiffness insulation joint .

The unitary insulation joint (directly buried and without maintenance)
is use of O&U type self-tightening sealing to seal the laminated section of insulating ring. Its completely avoid the moisture under the water pressure test and stop the soil moisture infiltrate the joint interior. we adopt the king of rubber (fluorine rubber) to seal, It makes function of anti-aging much more strong.meanhile,the working life of insulation joint are equate to the pipeline life.  

As the high insolation, credible sealing and same working life as the pipe, it dont need any maintenance and can be buried under the earth directly without the setting of observation well
