API 5L Seamless Steel Pipes

API 5L seamless steel pipes

        API 5L seamless steel pipes are pipeline steel pipes that comply with American Petroleum Institute standards. They are mainly used for the long-distance transportation of petroleum, natural gas, and water. Their characteristics include high strength, corrosion resistance, and suitability for high-pressure and high-temperature environments. The steel grades include GR.B, X42, X46, X52, X56, X60, X65, X70, etc.

a. Strict quality control

b. Extensive export experience

c. High-quality products

d. Thorough and professional service

        Manufactured using processes such as perforation, hot rolling, or cold rolling, the seamless structure provides higher pressure resistance and corrosion resistance. The manufacturing process requires strict temperature control and quality control to ensure uniform structure and mechanical performance.

Q: What is the minimum order quantity (MOQ)?

A:Standard products: 1 ton minimum order.Customized products: Depends on specifications (e.g., special alloy pipes may require 5 tons or more).

 

Q: What are the quality inspection standards for steel pipes?

A:Chemical composition analysis: Spectrometer testing of material composition.

   Mechanical property testing: Tensile testing, hardness testing.

   Non-destructive testing: Ultrasonic testing (UT), eddy current testing (ET), X-ray testing (RT).

  Hydrostatic testing: Verification of pressure-bearing capacity (e.g., API standard requires no leakage after 5 seconds of pressure retention).

 

Q: Does your company accept trial orders and small orders?

A:Yes.
