202 stainless steel pipe is a type of 200 series stainless steel, and its national standard model is 1Cr18Mn8Ni5N. 202 stainless steel pipe has good high temperature resistance and can maintain stable performance in high temperature environment. Usually, it will change phase only when heated to above 1000℃, and the performance does not change much at 350℃, which is suitable for use in high temperature environment.
Product use
Petrochemical industry includes fertilizer industry
There is a huge demand for stainless steel pipes. The industry mainly uses stainless steel seamless pipes, with specifications including: 304, 321, 316, 316L, 347, 317L, etc., with an outer diameter of about ￠18-￠610 and a wall thickness of about 6mm-50mm (generally, medium and low pressure transmission pipelines with specifications above Φ159mm are selected). The specific application areas are: furnace pipes, material conveying pipes, heat exchanger pipes, etc.
Fluid transportation such as water and gas
Stainless steel pipes and their water transportation equipment are the most advanced basic water purification materials in the world today. They have strong corrosion resistance and cannot be compared with cast iron pipes, carbon steel pipes, plastic pipes, etc.
The best material for water industry such as water preparation, storage, transportation, purification, regeneration, and seawater desalination. The annual demand is about 25,000 tons. The most commonly used stainless steels in the water industry are 304 and 316 stainless steels, which can meet most water treatment and transportation conditions.
