Quick Details Parameter

Material: Stainless Steel : Technics: Forged
Type: Coupling : Model Number: QDQ-JD

Description

1)Insulation: 

The insulation ring of rigid insulation joint is made of high

compression strength (not less than350N/mm2), low water absorption,high electrical insulating strength,

anti-aging materials. Insulation resistance

value is more than 10 m Ω. Because of it is

far greater than other insulation joint

resistance, greatly improving the insulation

and to reduce the leakage current. Another

sleeve (assembly) is annular space. It is

inject polymer composite material, low viscosity, cold solid heat hard

resin, and has certain compression strength, more can give full play to the

cathode protection, improve the protected the pipeline operation life.

2)Steel degree strong

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 to pipeline design), eliminate

the other insulation joint for structure is not rational caused by

insufficient stiffness caused by leakage accident.

3)Long lifespan:

The unitary insulation joint (directly buried and without maintenance)
is use of O&U type self-tightening seal, to sealed the laminated section of
insulating ring. It’s completely avoid the moisture of water pressure test
and soil infiltration insulation joint internal. Especially we adopt the king
of rubber (fluorine rubber) seal, It makes anti-aging degree strengthening,
also use life and pipeline life equate.
4)Applicable medium wide application
Rigid insulation joint adapt to the oil, gas and other non conducting
medium pipeline transport, also in the steam, pulp, such as water
dielectric to realize the cathodic protection. It need to users with medium
resistivity.
