Product Knowledge of 316 Stainless Steel Pipes

A1: Because 316 stainless steel pipes are added with 2%-3% molybdenum, which can effectively improve the pipe's resistance to harsh environments such as chloride ions, strong acids and alkalis, and seawater, making it not easy to corrode and rust.

Q2: What are the common specifications (outer diameter + wall thickness) of 316 stainless steel pipes?

A2: The common outer diameter range for foreign trade is 6mm-219mm, and the wall thickness is 1mm-10mm. Among them, the demand for pipes with outer diameter of 10mm-57mm and wall thickness of 1.5mm-3mm is the largest, which are suitable for scenarios such as pipeline transportation and equipment connection.

Q3: Can 316 stainless steel pipes be used in seawater desalination and chemical transportation scenarios?

A3: Yes, this is the core advantage scenario of 316 stainless steel pipes. They can resist corrosion from seawater and chemical media (such as dilute sulfuric acid and nitric acid), and are not easy to break and leak. They are widely used in overseas seawater desalination projects and chemical enterprises.

Q4: What are the requirements for foreign trade packaging of 316 stainless steel pipes?

A4: Foreign trade packaging needs to adopt waterproof, scratch-proof and anti-oxidation packaging. Usually, it is wrapped with pearl cotton + non-woven fabric, then loaded into wooden pallets, marked with specifications, materials, quantity and export marks, so as to avoid rust and deformation during transportation and meet international transportation standards.

Q5: How much higher is the price of 316 stainless steel pipes than 304 pipes?

A5: The price is usually 30%-50% higher than that of 304 stainless steel pipes of the same specification, mainly because of the addition of molybdenum and higher material costs. It is suitable for high-end foreign trade orders with high corrosion resistance requirements, and has better cost performance than other high-end stainless steel pipes.
