10CrNiCuP 20NC14 tube resistance to atmospheric corrosion welded corten B steel

Corten Steel Pipe

Corden steel pipe is mainly used for: air preheater, heat exchanger and evaporator, etc.Corden steel pipe is used to resist the condensation and corrosion of sulfur-containing flue gas. 

The grade of Corden steel pipe is Q345GNHL (09CuPCrNi-A/B), which contains a small amount of alloy elements with strong corrosion resistance such as Cu, P, Cr and Ni, and is widely used in power plants and oil refineries, boiler plants, petrochemical enterprises and other industries To resist sulfur corrosion.

Spiral grooved tubes are highly efficient, economical and mature heat transfer elements, which have been widely used in various boiler air preheater products. The spirally grooved tube uses the lotus-shaped inner wall and the spiral groove to guide the flow to forcibly disturb the working fluid in the tube, thereby improving the heat transfer efficiency. The heat transfer coefficient of spirally grooved tubes can generally reach 1.25 times that of light pipes of the same diameter. The use of spirally grooved tubes can improve the efficiency of heat exchange equipment, reduce the amount of steel pipes, and reduce the space occupied by heat exchange equipment. It has good economy and reliability Sex.
