Manufacturing process
Weatherproof steel
Weatherproof steels generally adopt refining-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire) - controlled rolling and cooling process.
09CuPCrNi/Q355GNH weatherproof steel pipes are made by the seamless process and shall be either hot-finished or cold-finished, as specified.

09CuPCrNi (Q355GNH) weatherproof steel pipe is made of ordinary carbon steel pipe with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of high-quality steel pipe, such as toughness, plasticity, forming, welding and cutting, abrasion, high temperature and fatigue resistance. Its weatherproof is 2-8 times of ordinary carbon steel pipe, and its coatability is 1.5-10 times of ordinary carbon steel pipe. At the same time, 09CuPCrNi/Q355GNH weatherproof steel pipe has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving.
Application
09CuPCrNi/Q355GNH weatherproof steel pipe is used for sulphur-containing flue gas, air preheater, economizer, air preheater of boiler, preventing acid dew point and so on.
