Product Knowledge of 316L Stainless Steel Pipe

Q1: What is the working pressure range of 316L stainless steel pipe for foreign trade?

A1: The common working pressure range is 0.6MPa-16MPa, and the pressure-bearing capacity is related to the wall thickness. The thicker the wall thickness, the higher the pressure-bearing capacity. It can be customized according to the pressure requirements of different industrial scenarios.

Q2: What are the common connection methods of 316L stainless steel pipe?

A2: The common connection methods are welding (argon arc welding, submerged arc welding), thread connection and flange connection. Welding is suitable for large-diameter pipes and high-pressure scenarios; thread connection is suitable for small-diameter pipes and easy disassembly scenarios.

Q3: Can 316L stainless steel pipe be used for seawater transportation?

A3: Yes, it is the preferred material for seawater transportation and seawater desalination projects. It can resist corrosion from seawater, marine organisms and chloride ions, and has a service life of more than 50 years in normal seawater environments.

Q4: What are the testing standards for 316L stainless steel pipe in foreign trade?

A4: The common testing standards are ASTM A312 (American standard), GB/T 14976 (Chinese standard) and JIS G3459 (Japanese standard). The main tests include pressure test, corrosion resistance test and dimensional accuracy test to ensure product quality.

Q5: What is the delivery time for customized 316L stainless steel pipe orders?

A5: For customized specifications (special outer diameter, wall thickness), the delivery time is 12-20 working days, depending on the order quantity and processing difficulty. For regular specifications, we have in-stock supply, and the delivery time is 3-7 working days.
