Product Details

What is GB8163-2008 Seamless steel pipe?

Ground seam steel pipe for conveying fluid, executive standard: GB8163-2008,
GB8163-2008 steel pipe has excellent corrosion resistance and cold stamping performance, has strong corrosion resistance to oxidizing acids (such as nitric acid), and has certain corrosion resistance to alkaline solutions and most organic acids and inorganic acids. General seamless steel pipes used to convey fluids such as water, oil, and gas.

GB8163-2008 steel pipe manufacturing method:

Generally, the operating temperature of boiler tubes is below 450°C, and domestic tubes are mainly made of No. 10 and No. 20 carbon-structured steel hot-rolled or cold-drawn tubes.
High-pressure boiler tubes are often under high temperature and high pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durable strength, high resistance to oxidation and corrosion, and good structural stability.

GB8163-2008 steel pipe use:

General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc.
High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.
GB8163 standard seamless steel pipe weight calculation formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/m (weight per meter)
