Insulating joint Product Introduction:

We developed Monolithic Insulating Joints type ZJ3 successfully, and passed technical appraisal presided over by the Tianjin Municipal Science and Technology Commission in April 2, 2008, and obtained a patent certificate.And our Products obtained CE certification.

Insulating joint product details:

Monolithic insulating joint is a high-tech product
It is very difficult to manufacture the monolithic insulating joint, it requires accurate design, precision machining and accurate assembly, the combination of a wide array of high-quality materials, strict quality inspection, so the monolithic insulating joint is multidisciplinary comprehensive high-tech product.

monolithic insulating joints
Operation pressure
up to 42 Mpa
Operation temperature
design temperature 250℃;(exported to Sudan Project)
Electric resistance
more than 10 MΩ at 2.5KV DC(direct current)
Dielectric strength
no breakdown at 50Hz, 3KV AC(alternating current)

The new type ZJ3 monolithic insulating joint

So the new type ZJ3 monolithic insulating joint has been treated as national key new product by Five National Ministries.Main Characteristics of the new type ZJ3 monolithic insulating joint.Assembled in factory, prefabricated monolithic structure.Strict mechanical and electrical inspection in factory.

The insulating Joints is a new generation developed product to resolve use problems of old insulating flange.

Can be buried directly Without any maintained.A variety of diameters and pressure, can meet the requirement of high, medium, low pressure steel pipeline for oil, water and gas.
