Chemical Hoses
SUCTION AND DISCHARGE HOSES (GCS)
Specifications
IS 7654 / 1975
Type I - Conveying diluted chemicals
Construction
Tube : Natural Rubber
Reinforcement : Multiple plies rubber impregnated strong woven fabric with helical steel wire, full-vacuum and discharge pressure, that vary according to size. Flexible construction keeps hoses round when bent, reducing kinking
and damaging
Cover : Black outer rubber cover resists abrasion, sunlight and weather
Type II - Conveying concentrated chemicals
Construction
Tube : Hypalon
Reinforcement : Multiple plies rubber impregnated strong woven fabric with helical steel wire, full-vacuum and discharge pressure, that vary according to size. Flexible construction keeps chemical hoses round when bent, reducing kinking
and damaging
Cover : Hypalon resists abrasion, sunlight and weather
Application
For suction and discharge service handling many inorganic acids, except strong oxidizing agent. Withstands most salts and alkalies.
Couplings
Couplings must be selected for corrosion and pressure
For special application alternate construction can be supplied.

Specifications
IS 7654 / 1987
Type I - Conveying diluted chemicals
Construction
Tube : Natural Rubber
Reinforcement : Multiple plies rubber impregnated strong woven abric or yarn braided
Cover : Black outer rubber cover resists abrasion, sunlight and weather
Ends : The ends of chemical hoses in length shall be securely sealed with rubber, 1.5 mm in thickness to prevent liquids coming into contact with the fabric reinforcement
