In the chemical industry, equipment often operates in complex environments, such as high temperature, high pressure, low temperature, corrosive media, and so on. Therefore, it is required to have steel that can withstand high temperature, high pressure, low temperature, and various corrosive media, such as structural or device steel that is resistant to sulfur or hydrogen sulfide, steel that is resistant to seawater corrosion, and steel that is resistant to low temperature. For example, steel that requires direct contact with various acid, alkali, or salt baths with higher corrosion resistance media. In design, it is of great significance to choose steel that meets technical requirements and is economical.

Petrochemical equipment manufacturing: The main demand of users is for seamless stainless steel pipes made of 1Cr18Ni9Ti material, with specifications ranging from 108mm to 325mm. They are mainly used for pressure fluid transportation pipelines, and their pipe blanks are mainly imported with domestic production as a supplement.

Dye chemical equipment manufacturing: The main needs of users are 300 series materials such as 304, 316, 316L, 310S, etc., cold-rolled stainless steel sheets with a thickness of 0.7mm to 3.0mm, and hot-rolled stainless steel medium plates with a thickness of 4mm, 5mm, 6mm, and 8mm; Material: 1Cr18Ni9Ti, specification: stainless steel seamless pipe with a diameter of 25mm to 80mm; Related stainless steel fasteners and plumbing components. The above materials are mainly used for atmospheric fluid transportation pipelines and various tanks and kettles.

Pharmaceutical and chemical equipment manufacturing: The main needs of users are 300 series materials such as 304, 309S, 316, 321, etc., cold-rolled stainless steel sheets with a thickness of 0.7mm to 3.0mm, and hot-rolled stainless steel medium plates with a thickness of 20mm to 50mm; Material: 1Cr18Ni9Ti, specification: stainless steel seamless pipe with a diameter of 25mm to 80mm; Supporting stainless steel fasteners and plumbing components.
