Petrochemical industry

Application fields of special alloys in petroleum industry:

Petroleum exploration and development is a multi-disciplinary, technology-intensive and capital-intensive industry that needs to consume a large number of metallurgical materials and products with different properties and uses. With the development of ultra-deep and ultra-inclined oil and gas wells and oil and gas fields containing H2S, CO2 and Cl -, the application of stainless steel materials with anti-corrosion performance requirements is increasing.

The development of petrochemical industry and the renewal of petrochemical equipment have put forward higher requirements for the quality and performance of stainless steel. The requirements for corrosion resistance, high temperature resistance and low temperature resistance of stainless steel are not relaxed but stricter. At the same time, the petrochemical industry is also a high temperature, high pressure and toxic industry, which is different from other industries. The consequences of mixing materials are not obvious. Once the quality of stainless steel materials in the petrochemical industry cannot be guaranteed, the consequences will be unimaginable, Therefore, domestic stainless steel enterprises, especially steel pipe enterprises, should improve the technical content and added value of products as soon as possible to occupy the high-end product market.

Commonly used in reactors in petrochemical equipment, oil well tubes, polished rods in corrosive oil wells, spiral tubes in petrochemical furnaces, and parts and components on oil and gas drilling equipment.
