Description

Casing spacers are designed to support and electrically isolate a carrier pipe from its casing in order to prevent bi-metallic corrosion and also to protect carrier pipe coating from damage. The spacers are available in various sizes from 3/4-48'' and also in molded polyethylene or steel to obtain higher durability.

Application

Casing spacers dialetically insulate gas, oil and water pipes from casting to prevent corrosion. They also provide support to the pipeline and proect pipe coatings during installation. To allow for sufficient lateral movement of the carrier pipe, the spacers should be installed with runners facing the sides or base of the casting.

Feature

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