Seamless Stainless-Steel Tube for Technical Gases, Hydrogen & Oxygen - SKA 150
- The SKA 150 is a precision-engineered, seamless stainless-steel tube developed specifically for demanding technical-gas systems, especially hydrogen and oxygen service and for use with compression couplings.
- Manufactured from high-grade 1.4404 / 1.4435 stainless steel and finished to rigorous cleanliness, hardness and surface-roughness standards, the tube delivers leak-tight safety, universal compatibility and simplified logistics.
- PE-capped ends and individual heat-sealed poly-bags protect every tube in transit, while convenient 2 m stock lengths (6 m on request) save space and speed installation on-site.
- For years, engineers had to specify a different tube grade for each application, one for high-pressure hydrogen, another for oxygen, another for coupling assemblies, forcing big inventories and frequent errors.
- Working closely with gas-system builders, refuelling-station operators and compressor manufacturers, MST Edelstahlrohr defined a single tube that would satisfy all of those requirements yet cost no more than a standard industrial tube.
- After exhaustive trials MST Edelstahlrohr has reached full production readiness, and SKA 150 was born a universal tube that slashes part numbers, simplifies procurement and streamlines every stage from design to commissioning.
Key features
- One tube grade covers hydrogen, oxygen, compressed-gas, coupling and compression applications, reducing part numbers and error risk.
- Ready-to-install 2 m lengths cut warehouse footprint and handling time; 6 m lengths available for manifold builds.
- Supplied to ASTM A632 S3 “TCC” requirements; oxygen-service ready right out of the bag.
- Max Ra 0.8 µm (OD and, for OD ≥ 10 mm, ID) ensures low pressure drop and system cleanliness.
- Hardness controlled to ≤ 90 HRB (> 1.65 mm wall) or ≤ 160 HV (≤ 1.65 mm wall) for optimum forming and coupling performance.
- PE end caps and tear-resistant heat-sealed film prevent contamination and damage during transport.
Technical specifications
- Material: Stainless steel 1.4404 / 1.4435
- Outer-diameter range:6.00 mm (¼″) – 30.00 mm (1 ½″) ex-stock
- Standard length: 2 m (6 m on request)
- Cleanliness: ASTM A 632 S3 “TCC”; oil- & grease-free for oxygen service
- Hardness: ≤ 90 HRB for wall > 1.65 mm; ≤ 160 HV for wall ≤ 1.65 mm
- Surface roughness (Ra): OD ≤ 0.8 µm; ID ≤ 0.8 µm for OD ≥ 10 mm
- End protection / packaging: PE caps on both ends; individually heat-sealed poly-bags
Application areas
- Hydrogen refuelling stations
- Hydrogen dryers and purification skids
- Hydrogen pumps and compression systems
- High-pressure hydrogen storage banks
- General technical-gas supply lines using compression fittings
