alloy pipe

Alloy pipe is a kind of seamless pipe, but the performance of alloy tubes is much higher than seamless steel tubes. Because alloy pipe contains much more Cr inside, high temperature resistance, low temperature resistance, corrosion resistance is higher than other seamless steel tubes; alloy tubes have wide applications in oil, aerospace, chemical, electric power, boiler, and military industry etc. Moreover, alloy tubes are made of high quality carbon steel, alloy structural steel and stainless heat resistant steel by hot rolling and cold rolling.

Advantages:

Alloy steel pipe can be 100% recovery and in accord with environmental protection, energy and resource saving.

The Classification of Alloy Steel Pipe: Alloy pipe for structure and high pressure heat resistant alloy pipe
