UNS N08904 Stainless Steel 904L Welded Pipes

SMO 354 Tubes are high-alloy austenitic stainless steel tubes manufactured from UNS S31266, offering excellent resistance to pitting, crevice corrosion, chloride stress corrosion cracking, and acidic environments. These tubes are widely used in offshore, desalination, chemical processing, marine, pulp & paper, and heat exchanger applications requiring superior corrosion resistance and long service life.

Detailed Information

SMO 254 Pipe/Tube Manufacturer & Supplier in Chile

We are one of the trusted SMO 354 tube manufacturers, supplying premium-quality tubing for demanding industrial applications where conventional stainless steel grades are not sufficient. Our SMO 354 Tubes are manufactured according to international quality standards and undergo strict testing to ensure exceptional corrosion resistance, dimensional accuracy, and long-term performance.

Manufactured from UNS S31266, these tubes contain high levels of chromium, nickel, and molybdenum, making them highly resistant to pitting corrosion, crevice corrosion, and chloride-induced stress corrosion cracking. They are extensively used in seawater systems, offshore platforms, desalination plants, chemical processing facilities, power generation, and heat exchanger equipment.

Whether you require precision tubing, process piping, or UNS S31266 heat exchanger tubing, we offer seamless and welded solutions in multiple sizes, wall thicknesses, and finishes to meet project specifications worldwide.

ASTM A312 UNS S31266 Pressure Rating

The ASTM A312 UNS S31266 pressure rating depends on several engineering factors including:

  • Outside diameter
  • Wall thickness (Schedule)
  • Operating temperature
  • Design code (ASME B31.3, B31.1)
  • Corrosion allowance
  • Safety factor

Because pressure ratings vary according to tube dimensions and operating conditions, engineers typically calculate the allowable working pressure using ASME design formulas. We help customers select the appropriate schedule and dimensions based on their project requirements while ensuring compliance with applicable standards.
