Enquire Now

Specification

IS 7654 / 1975

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 hose round when bent, reducing kinking and damaging
  • Cover: Hypalon resists abrasion, sunlight and weather

Type II - Conveying concentrated 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 hose round when bent, reducing kinking and damaging
  • Cover: Black outer rubber cover resists abrasion, sunlight and weather

Application

For suction and discharge service handling many inorganic acids, except strong oxidizing agent. Withstands most salts and alkalies.

End Connection

Couplings must be selected for corrosion and pressure
For special application alternate construction can be supplied.
