ASTM A312 TP904L stainless Steel Pipe Large Outside Diameter For Chemical / Oil / Marine

Yuhong Special Steel has been operating seamless welded pipes and tubes for austenitic stainless steel and nickel alloy steels (Hastelloy, Monel, Inconel, Inkoloy) for more than 25 years, and sells steel tubes and tubes every year. More than 80,000 tons. Our customers have covered more than 45 countries, such as Italy, the United Kingdom, Germany, the United States, Canada, Chile, Colombia, Saudi Arabia, Russia, South Korea, Poland, Singapore, Australia, France, etc.

 

 

Description

Material 1.4539(alloy 904L) is an austenitic special steel with high molybdenum content, high copper content and very low carbon content.


Our product range in 1.4539 are tubes and pipes, fittings and flanges, accessories.

 

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
