Monolithic Insulating Joints for Pipeline Cathodic Protection

Monolithic Insulating Joints (MIJ for short) are developed in cathodic protection to steel pipeline system which is used to replace the insulating flanges. MIJ is more convenient in field installation. What the user need to do is welding the MIJs to nominated pipeline and work with the cathodic protection system together to provide anti-corrosion protection. The pipeline without cathodic protection is very easy to be corroded in 3 years. But the pipelines which are applied the cathodic protection will work as long as more than 30 years. So MIJs are more and more widely used in long distance pipeline.
What we provide to customers is the first class quality monolithic insulating joints in China even in all over the world. The MIJs are manufactured by the famous insulating joint manufacturer of China whose name is Langfang VBA Mechanical Co.,Ltd. Patented U-Sealing system is used in our MIJs which provides a more stable sealing performance compared to the O-Sealing System. The structure is designed as per ASME VIII DIV1 APP 2. Besides the standard products we also accept custom making order as per the specification and data book of customers.
