  The stainless steel pipes in petrochemical industry, including the fertilizer industry, has a huge demand The stainless steel pipe in petrochemical industry mostly used is stainless steel seamless pipes , in 304, 321, 316, 316L, 347, 317L, etc, with OD around ￠18-￠610, and the WT around 6mm-50mm (generally, the selection specification is above Φ159mm). Specific applications are: furnace pipes, fluid pipes, heat exchanger tubings , etc. Heat-resistant stainless steel pipes are mainly used for heat exchange and fluid transportation. The Chinese market has an annual capacity of about 200,000 tons. Duplex stainless steel pipes are mainly used in fluid pipes and heat exchangers for chemical and fertilizers. Because of their high strength, stress resistance, corrosion resistance and economy, their annual consumption is about 8,000-10,000 tons. Stainless steel pipes , the pipes used in oilfield drilling and production is super ferritic stainless steel Cr13, Cr25, etc., which is highl...

Is It Possible To Judge The Quality Of  Magnetic   Stainless Steel Is unqualified? Most people think that magnetic stainless steel is bad, and use magnets to judge the quality of  stainless steel pipe and fittings . It is definitely unscientific. magnet There are many types of stainless steel, which can be divided into several categories according to the organizational structure at room temperature: Austenite type such as 304, 321, 316, 310, etc.; Martensite or ferrite type such as 430, 420, 410, etc.; The austenitic type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic. Why some stainless steels magnetic The stainless steel commonly used for decorative tubes/plates is mostly austenitic 304, which is generally non-magnetic or weakly magnetic. However, due to chemical composition fluctuations or different processing conditions caused by smelting, magnetism may also appear, but this cannot be considered It is unqualified. What is th...
