Alloy steel pipes are mainly used in high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , formed by hot rolling (extrusion, expansion) or cold rolling (drawing).
What is seamless Alloy Steel Pipe?
Alloy steel pipes are steel pipes composed of alloy elements and are usually used in special environments such as high temperature, high pressure, and corrosion resistance.
Types of alloy steel pipes
Alloy seamless steel pipes can be divided into low alloy steel pipes and high alloy steel pipes according to their chemical composition. Low-alloy steel pipes refer to steel pipes with an alloying element content of less than 5%, and high-alloy steel pipes refer to steel pipes with an alloying element content of more than 5%.
The uses of alloy steel pipes are:
Used for low and medium pressure boiler heating surface pipes (working pressure is generally not greater than 5.88Mpa, working temperature is below 450°C).
It is used in heating surface pipes, economizers, superheaters, reheaters, petrochemical industry pipes, etc.
We can also supply Carbon Steel Pipe, APl Line Pipe, Galvanized Pipe in any form.
