ASTM A312 TP 904L Large Outside Diameter Stainless Steel Alloy Pipe For Chemical/Oil/Marine

Yuhong Special Steel has been dealing in seamless welded pipes and tubes of austenitic stainless steel and nickel alloy steel (Hastelloy, Monel, Inconel, Inkoloy) for more than 25 years, and has sales of steel pipes every year. Over 80,000 tons. Our customers have covered more than 45 countries including Italy, Britain, Germany, the United States, Canada, Chile, Colombia, Saudi Arabia, South Korea, Poland, Singapore, Australia, France, etc.

Originally intended for those applications involving dilute sulfuric acid, 904l stainless steel tubing is widely used in the chemical processing industry. Specifically, stainless steel 904l pipe or also known as UNS N08904, used in the production of phosphate based fertilizers. 904l seamless pipe is considered a super austenitic stainless grade with added molybdenum and copper content in its alloy to enhance its mechanical or corrosion resistance.

Description

Material 1.4539 (Alloy 904L) is an austenitic special steel with high molybdenum, high copper and very low carbon content.
Our product range in 1.4539 includes pipes, fittings and flanges, fittings.

Some of the quality tests carried out by our quality department includes:

Corrosion Test Only when specifically requested by the customer
Chemical Analysis Conduct tests according to required quality standards
Destructive / Mechanical Testing Tensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat tests Fully compliant with relevant standards and ASTM A-450 and A-530 specifications, ensuring trouble-free extension, welding and use on the client side
Eddy Current Testing Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing 100% hydrostatic test, check pipe leaks according to ASTM A 450 specification, the maximum pressure we can support is 20Mpa/7s.
Air Under Pressure Test Check for any signs of air leakage
Visual Inspection After passivation, each tube is subjected to a thorough visual inspection by trained personnel to detect surface defects and other defects


Supplementary Testing : In addition to the above tests, we also carry out supplementary tests on finished products. Tests carried out in this regard include:

  • Eddy Current Testing
  • O.P Testing
  • Radiography Testing
  • Corrosion Testing
  • Micro Testing
  • Macro Testing
  • IGC Testing
  • Ultrasonic testing
  • Liquid Penetrate testing
