SS Pressure Tubing

High-pressure stainless steel (SS) tubing is seamless, corrosion-resistant, and engineered to withstand extreme pressures—commonly used in oil & gas, chemical, aerospace, and hydraulic systems.

🔩 Key Characteristics of High-Pressure SS Tubing

• Material Grades:
  • Most commonly 316L stainless steel for corrosion resistance and weldability.
  • Specialty grades like HP120™ and HP160™ offer enhanced strength for ultra-high pressure applications.
• Pressure Ratings:
  • Medium pressure: up to 20,000 psi
  • High pressure: 30,000–60,000 psi
  • Ultra-high pressure: up to 90,000 psi

 Construction:

• • Seamless and cold-drawn for maximum integrity.
  • 1/8 hard austenitic structure ensures strength and flexibility.
  • Wall thickness designed per ASME B31.3 Chapter IX for high-pressure piping.
• Dimensions:
  • Typically supplied in lengths of 20 to 27 feet.
  • Available in various outer diameters and wall thicknesses to suit system requirements.

Standards:

• Manufactured to ASTM A213 and ASTM A269 (chemistry only) standards.

Applications

• Oil & Gas:
  • Surface and subsea hydraulic control lines
  • Chemical injection systems
  • Pressure testing and sampling lines
• Industrial & Aerospace:
  • Waterjet cutting systems
  • Hydraulic power units
  • High-pressure gas delivery systems
• Testing Equipment:

• Integrated into test wells, booster systems, and load cell assemblies for product validation.
