Product Knowledge of 316L Stainless Steel Seamless Pipes

Q1: What is the advantage of 316L stainless steel seamless pipes with no intergranular corrosion risk?

A1: Because its carbon content is ≤0.03%, there will be no intergranular corrosion after welding. The corrosion resistance and mechanical properties of the welds are consistent with the base metal, which can be used for high-pressure and strong corrosion scenarios that require welding and long-term use, with longer service life.

Q2: What are the common pressure and temperature ranges of 316L stainless steel seamless pipes?

A2: The common working pressure for foreign trade is 0.6MPa-16MPa, and the temperature range it can withstand is -270℃ to 800℃, which is suitable for high-pressure pipeline transportation, low-temperature equipment connection and high-temperature working conditions, and can meet the strict requirements of different industrial scenarios.

Q3: Which industries are the main foreign trade export destinations of 316L stainless steel seamless pipes?

A3: They are mainly oriented to high-end industrial industries such as petrochemical, natural gas, seawater desalination, pharmaceutical and electric power, for pipeline transportation and equipment connection, especially suitable for harsh environments such as coastal areas, chemical industry, high pressure and low temperature, and are the core category of high-end foreign trade industrial pipes.

Q4: What are the requirements for the dimensional accuracy of 316L stainless steel seamless pipes?

A4: Foreign trade orders have high requirements for dimensional accuracy. The outer diameter tolerance is ≤±0.05mm, the wall thickness tolerance is ≤±0.1mm, the wall thickness is uniform, no deformation and no burrs, ensuring smooth installation and adapting to the connection needs of high-end equipment, which needs to pass professional accuracy testing.

Q5: What is the price difference between 316L stainless steel seamless pipes and 304L seamless pipes?

A5: The price is 40%-60% higher than that of 304L stainless steel seamless pipes of the same specification, mainly because of the addition of molybdenum and higher process requirements. However, their corrosion resistance, high temperature resistance and pressure-bearing performance are better, suitable for high-end foreign trade orders, and have higher cost performance in long-term use.
