introduction

SA335 P11 high temperature steel pipe is a 1Cr-1/2Mo pearlite type low alloy heat strength steel. The material has good process performance and welding performance, and has high thermal strength and oxidation resistance below 550°C.
A335 P11 alloy steel pipe is relatively close to the 15CrMoG in GB5310, and is widely used in heating surface piping systems such as superheaters and reheaters of boilers such as 300MW and 600MW with operating temperatures not exceeding 550°C, as well as headers, main steam pipes, etc.

A335 P11 Seamless Steel Pipe High-pressure boiler steel pipe is mainly used to manufacture carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes for steam boiler pipes of high pressure and above. These boiler pipes are often exposed to high temperatures and pressures. When working under high temperature, the pipes will also undergo oxidation and corrosion under the action of high-temperature flue gas and water vapor. Therefore, the steel pipes are required to have high strength, high soothing reaction performance and good preparation stability.
