Seamless pipe production Classification-hot-rolled pipe, cold rolling pipe, cold-drawn pipe, extruded pipe, top tube.

1. Structural Seamless steel pipe (gb/t8162-2008) is used for general structure and mechanical structure of seamless steel tubes.

2. Fluid Transport Seamless Steel pipe (gb/t8163-2008) is used for conveying water, oil, gas and other fluids of the general seamless steel tube.

3. Low-medium-pressure boiler seamless steel pipe (gb3087-2008) is used for the manufacture of various structures of low medium pressure boiler superheated steam pipes, boiling water pipes and locomotive boilers with superheated steam pipes, opium pipes, small smoke pipes and arch bricks for the use of high-quality carbon structural steels hot rolling and cold (rolling) seamless steel tube

4. High-pressure boiler seamless steel pipe (gb5310-2008) is used for the manufacture of high-pressure and above the pressure of the water pipe boiler heating surface of high-quality carbon steel, alloy steel and stainless steel pipe.

5. High-pressure seamless steel pipe for fertilizer equipment ($literal) is a high quality carbon structural steel and alloy steel seamless steel pipe for the working temperature-40~400℃, working pressure for ~ chemical equipment and pipelines.

6. The petroleum cracking seamless steel tube (gb9948-2006) is applies to the petroleum refinery the stove tube, the heat exchanger and the pipeline seamless steel tube.

7. The geological Drilling pipe (YB235-70) is a steel pipe used by the geological Department for Core drilling, which can be divided into drill pipe, drill collar, core tube, casing and settling pipe.

8. Diamond Core drilling Seamless steel pipe (gb3423-82) is used for diamond core drilling drill pipe, core rod, casing seamless steel pipe.

9. The oil drilling pipe (yb528-65) is a seamless steel tube used in both ends of oil drilling. The steel pipe is divided into two kinds of wire and not, the wire is connected with the wire, the method of butt welding is connected with the tool joint.

10. Marine Carbon Steel Seamless pipe (gb5213-85) is the manufacture of ship I-class pressure-resistant pipe system, Ⅱ-class pressure-resistant piping, boilers and superheater steel seamless steel tubes. Carbon steel seamless steel pipe wall operating temperature of not more than 450 ℃, alloy steel seamless steel pipe wall operating temperature of more than 450 ℃.
