As an important part of the chemical industry, the petrochemical industry includes many production sectors, such as fertilizer, rubber, synthetic materials and so on. Petrochemical industry is the basic industry of economic development, involving many aspects of the real economy.

At present, 99.1 tons of stainless steel pipes are needed for overhaul and replacement of a set of polyene phenol device, among which 53.79% of large diameter stainless steel pipes with ф 108-630mm account for 53.79%. For example, a large scale urea plant with 520,000 tons of urea and 300,000 tons of ammonia synthesis requires a total of 2018.5 tons of process pipelines, heat exchanger pipes, “urea grade” special pipes, dual-phase stainless steel pipes and various other steel pipes.

Petrochemical industry including chemical fertilizer industry, the demand for stainless steel tube is great, the industry mainly uses stainless steel seamless tube, specifications include: 304, 321, 316, 316L, 347, 317L, etc., the outer diameter is about ¢18-¢610, the wall thickness is about 6mm-50mm (generally choose specifications in φ 159mm above the medium and low pressure pipeline), the specific application field is: furnace tube, material conveying tube, heat exchanger tube, etc. Such as:

Heat resistant stainless steel pipe, mainly used for heat exchange and fluid transport, domestic market capacity of about 230,000 tons per year, high-end demand still need to rely on imports.

Duplex stainless steel tube, mainly used in chemical, chemical fertilizer heat exchanger and fluid tube market, because of its high strength, stress resistance, corrosion resistance and economic, its annual consumption of about 8000-10000 tons.

According to rough statistical analysis, the annual consumption of stainless steel oil casing, such as non-magnetic drill collar of stainless steel, Cr13 and Cr25 of super ferritic stainless steel with high corrosion resistance of CO, CO2 and Cl-corrosion, is more than 20,000 tons, and about 50,000 to 60,000 tons will be needed in 3 to 5 years. However, the import volume of this kind of stainless steel pipe is still large.
