Chemical Hoses

SUCTION AND DISCHARGE HOSES (GCS)

Specifications

IS 7654 / 1975

product

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 hoses round when bent, reducing kinking and damaging
Cover : Hypalon resists abrasion, sunlight and weather
product

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.

  • Tube : Nitrile, Neoprene, Butyl, SBR, EPDM, Thiokol
  • Cover : Nitrile, Neoprene, Butyl, SBR, EPDM, Thiokol
