Coal coking, coal gasification, synthetic ammonia fertilizer and other fields dominate the domestic coal chemical industry, and they are developing faster and faster. Because the contradiction between domestic oil supply and demand has become more prominent, the production and application of the coal and coke industry are also constantly improving. Therefore, stainless steel composite panels are increasingly used.

For the coal coking industry, since pipelines and equipment will be exposed to high temperature and highly corrosive environments for a long time during actual use, the corrosion of the equipment will be serious, resulting in a greatly reduced service life of the equipment. Therefore, how to enhance the corrosion resistance of equipment, extend the service life of equipment, and reduce the production cost of enterprises is the key to enhancing the competitiveness of enterprises.

To achieve this goal, using stainless steel is a very good way. There are many types of stainless steel materials. The main ones that can be used in the above industries are 316, 316L, etc. In addition, high-quality stainless steel composite plates can also be used.

Stainless steel composite plate is a composite metal material with an outer layer of pure stainless steel and an inner layer of carbon steel. The emergence of stainless steel composite plate effectively provides material guarantee for the manufacturing and upgrading of coking equipment.

When stainless steel composite plates are used to replace the original pure stainless steel plates, the material cost of the equipment can be greatly reduced, and the performance of the equipment will not be greatly affected. Stainless steel composite plates can be used to make desulfurization towers, ammonia evaporation towers, benzene removal towers, etc., which are relatively low-cost and corrosion-resistant. Taking the benzene removal tower as an example, using stainless steel composite plates instead of pure stainless steel plates can reduce the cost by 30 % of the cost.

The second is that the stainless steel composite plate retains the corrosion resistance, wear resistance, antimagnetic properties and beautiful appearance of pure stainless steel, and also has the excellent weldability, formability, stretchability and thermal conductivity of carbon steel. . It can be widely used in coking equipment to increase the corrosion resistance of stainless steel coking equipment and extend the service life of the equipment.

The third is that stainless steel composite panels have very good thermal conductivity and corrosion resistance, and can be widely used in coking equipment. For example, using it in an ammonia evaporation tower can enhance the service life of the ammonia evaporation tower and reduce operating costs.

Generally speaking, stainless steel composite plates have a lot of available space in equipment manufacturing, upgrading and transformation in the coking field, which can effectively extend the service life of equipment, increase equipment production efficiency, and reduce operating costs.
