Hoses and fittings for technical gases

Hoses for technical gases include low pressure hoses (for acetylene, oxygen, propane-butane, natural gas, inert gases) as well as high pressure ones with working pressure above 140 bar (e.g. for filling up/ gas cylinders).While choosing appropriate hose for technical gas such aspects as: type of gas, working pressure, working temperature, gas permeation, required electrostatic properties, gas flow, required standards, safety factors must be taken into consideration. For other types of hoses for technical gases see: PTFE hoses, steel hoses and chapter HIGH PRESSURE.

LOW PRESSURE HOSES FOR TECHNICAL GASES

LOW PRESSURE HOSES FOR TECHNICAL GASES

Hoses designed for welding applications (acetylene, oxygen, propane-butane), LPG, natural and inert gases. Hoses dedicated to oxygen blowing lances made of rubber and PVC with textile cord or braid. DN from 4 to 102 mm, working pressure to 30 bar, according to EN 559 (welding hoses) and EN 1762 (hoses for LPG and natural gas transfer) standards. Fittings assembled with the use of worm drive hose clamps or crimped (ferrules).

HIGH PRESSURE HOSES FOR TECHNICAL GASES

HIGH PRESSURE HOSES FOR TECHNICAL GASES

Hoses designed for gases with working pressure above 140 bar. Widely used for filling up/emptying gas cylinders, industrial processes, medical and laboratory applications. Most typical gases are oxygen, nitrogen, hydrogen, helium, argon, carbon dioxide, acetylene, and many more. Our offer includes two types of high pressure hoses for technical gases:

  • PTFE smoothbore hoses with stainless steel braid,
  • corrugated stainless steel hoses with stainless steel braid.

Wide range of DN form 6 to 12 mm, working pressure to 300 bar. For high pressure technical gasses we can also use high pressure thermoplastic hoses UHP hoses SPIR STAR hoses.

FITTINGS FOR HIGH PRESSURE TECHNICAL GASES

FITTINGS FOR HIGH PRESSURE TECHNICAL GASES

Fittings for high pressure hoses have connections according to PN-81/M-69229 and DIN 477-1 standards (specified connection for a particular type of gas). Fittings material must be resistant to medium being transferred. Made of stainless steel AISI 304 (brass nut) as a standard and designed for a type and size of hose they are to be assembled on. Custom made connections according to customer specification, different standards, type of material are available on request.
