Thick wall seamless steel pipe chemical composition

Mainly produced outside diameter of 177mm-377mm GB spiral steel pipe wall thickness wall thickness 16mm-100mm outer diameter accuracy of ± 0.5% wall thickness accuracy of ± 5% you know seamless steel pipe hot rolled seamless steel pipe. Made of steel pipe 10 # 20 # 45 # 16Mn 20Cr 40Cr look. Roll pipe mill can produce material 20 #, 16Mn outer diameter of 400-1600mm, wall thickness 20-60mm thick want to know Shenzhen seamless spiral steel pipe wall steel pipe can be cut to length to 16 meters practical:

 

Knowledge of steel - seamless steel pipe 10, the marine carbon steel seamless pipe (GB5213-85) is manufactured GB spiral steel pipe ship I level pressure piping systems, Ⅱ level pressure piping, boilers and over you see the national standards of the spiral steel pipe thermal Used for carbon steel seamless steel tubes. Carbon steel seamless pipe wall Affairs temperature does not exceed 450 ℃ alloy steel seamless steel pipe wall thing Seamless Steel Tube Plant Works temperature exceeds 450 ° C 14, cold drawn or cold rolled precision

 

The large caliber divided into seamless steel pipe fertilizer (GB6479-2000) equipped with high-pressure seamless steel pipe seamless steel pipe elbow is applicable to the affairs temperature -40 ~ 400 ℃ Affairs pressure of 10 ~ 30Ma listen seamless steel pipe Chemical equipment and pipeline quality carbon structural steel and alloy steel seamless steel pipe [∮ 25-426 × 6-40] 6. petroleum cracking (GB9948-88) is suitable for the oil refinery compare seamless steel pipe furnace tube heat exchange

 

American standard seamless steel pipe price to see yesterday its manufacturing process and the tube shape is divided into welded steel pipe (plate, seamless steel pipe grid steady the standing steel pipe varieties: structure seamless steel pipe seamless steel pipe, fluid, hydraulic seamless steel pipe, seamless steel tubes for power, oil transportation with seamless steel tubes, fertilizer equipment, seamless steel tubes, compare the small-diameter seamless steel pipe for coal mine seamless steel pipe, stainless steel seamless pipe seamless steel pipe, chemical, textile machinery I do not know the national standards of the spiral steel pipe, seamless steel tubes, automotive; water applications seamless steel pipe

 

Rolled seamless steel pipe seamless steel tubes made of high-quality carbon steel or alloy steel hot-rolled, cold-rolled (pull),. Welded steel pipe because it is rolled into a tube-shaped steel plate welded steel pipe, spiral welded steel pipe seam or spiral seam welded making way into the high-pressure fluid delivery, directly welded steel pipes, electricity compare spiral steel national standard welded pipe. Seamless steel pipe can be used for a variety of liquid and gas pipeline.
