Professional China Stainless Steel Pipe Coupling - Fireproof Coupling – Grip

Technical Parameter: 【VIEW】

PRODUCT DETAILS

The Grip-GF combines with functional design with the latest technologies. The GRIP-GF is based on the proven coupling technology, which has been developed for the shipbuilding industry, also is successfully used for tunneling, fire hose applications etc. In the event of a fire, GRIP-GF coupling protectively enclosing the coupling. During this process, the coupling retains its full operational capability without any damage.

Suitable for pipes O.D φ26.9-φ273mm

Suitable for pipes material: Carbon steel, stainless steel, copper, cunifer, GRE, and other material

The GRIP-GF represents the ultimate in high security fire protected mechanical pipe couplings.

The advantage of grip fire proof type coupling

1. No thick smoke and smell after burning rubber when fire, will not be choking.

2. Not only keep coupling and pipe well, also protect personnel from rubber smoke dust and smell.
