As a new environmentally friendly material, stainless steel is currently used in many fields, such as the petrochemical industry, furniture industry, electronics industry, catering industry, etc. Now let’s take a look at the application of stainless steel pipes in the petrochemical industry.
The petrochemical industry, including the fertilizer industry, has a huge demand for stainless steel pipes. This industry mainly uses stainless steel seamless pipes, with grades and specifications including: 304, 321, 316, 316L, etc. The outer diameter is around ￠18-￠610, and the wall thickness is around 6mm-50mm (usually medium and low-pressure transportation pipes with specifications above Φ159mm are used). The specific application areas are: furnace tubes, material transportation pipes, heat exchanger tubes, etc.For example
1. Heat-resistant stainless steel pipes: mainly used for heat exchange and liquid transportation. The domestic market capacity is about 230,000 tons, and high-end ones need to be imported from abroad.
2. Stainless steel oil casing: Stainless steel non-magnetic drill collars, high resistance to CO, CO2 and other oil casing used in oilfield drilling. According to rough statistical analysis, this stainless steel pipe still needs to be imported.
In addition, the potential market for the petrochemical industry is large-diameter pipes for petroleum cracking furnaces and low-temperature transportation pipes. Due to their special requirements for heat resistance and corrosion resistance and the inconvenience of equipment installation and maintenance, the service life of the equipment is required, and the material composition needs to be determined. Control mechanical properties and performance. Another potential market is stainless steel pipes for the fertilizer industry. The main steel grades are 316Lmod and 2re69.
As an important part of the chemical industry, the petrochemical industry includes many production departments, such as chemical fertilizers, rubber, synthetic materials and other industries. The petrochemical industry is the basic industry for economic development and involves many aspects of the real economy. Of course, there are also stainless steel pipes and output equipment for conveying fluids such as gasoline, kerosene, diesel, etc., which have strong anti-corrosion properties and cannot be compared with cast iron pipes, carbon steel pipes, plastic pipes, etc.
