Specifications

Chem PGS /PSS Composite hose
Used for chemically compatible and mechanically engineered

Bencheng Chem PGS /PSS Composite hose

Note: P= Polypropylene coated steel GS= Galvanized steel SS= Stainless steel 316/304

Manufacture
Bencheng Chem PGS /PSS hoses are constructed from multi-layers of thermoplastic films which form a sealing and permeation barrier, supported by fabric layers for mechanical strength. The hose layers are held and tensioned by internal and external steel wire helices. All hoses meet the international standards including EN13765, BS 3492(1987)AX + BX and BS5842(1980) and can be supplied with external swaged and factory-fitted end connections to the customers’ requirements.

Applications
Bencheng chem PGS /PSS hoses are chemically compatible and mechanically engineered for those chemicals which do not affect the polypropylene lining and the polypropylene steel inner wire.
