Products Description

General Information

In many countries, pipelines crossing or running parallel to highways and railways are protected by casing. Casing Insulators are used to separate the carrier pipeline from the casing pipeline, it is suitable for water and oil & gas carrier pipeline.
Product Features / Benefits:

* High electrical insulating value and low water absorption,thus preventing leakage and maintaining electrical isolation between carrier and casing
* Ribbed inner surface prevents slippages and guards against coating damages.
* High compressive strength to support the carrier pipe weight.
* Resist mechanical damage while being pulled into the casing.
* Resistant to mechanical and thermal shocks and stresses,particularly that occur during installation and inserting operations.
