Such as precision stainless steel seamless pipe for petroleum cracking (GB9948-2006) is the seamless steel pipe used in oil refinery furnace tubes, heat exchangers and pipe.
, steel tubes for drilling (YB235-70) is for the Geological Department of the steel core drilling use, use can be divided into drill pipe, drill collar, core pipe, casing and precipitation etc..
8 diamond core drilling seamless pipe (GB/T3423-82) is used for seamless steel pipe, core rod, casing of diamond core drilling.
Oil drilling pipe, seamless steel pipe (YB528-65) is used for oil drilling in the thick thick or ends. Sub car steel wire and wire the two cars, car fittings connecting wire tubes, the methods and tools of threading work butt joint.
We use carbon steel seamless pipe (GB5312-2009) ship manufacturing ship I level pressure piping, II level pressure piping,
Boiler and Superheater carbon steel seamless steel pipe. Carbon steel seamless steel pipe wall temperature does not exceed 450 degrees, alloy steel seamless steel pipe wall temperature exceeding 450 DEG C.
2 automotive half shaft casing seamless steel pipe (GB3088-82) is the manufacture of automobile axle casing and drive axle shell tubes of high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel tube.
The diesel engine with high pressure tubing (GB3093-2002) is the manufacture of high-pressure diesel injection systems for seamless steel pipe.
People with precision internal diameter seamless steel tube for hydraulic and pneumatic cylinder (GB8713-88) is a manufacturer of hydraulic and pneumatic cylinder with precision diameter with cold drawn or cold-rolled precision seamless steel tube.
All the cold drawn or cold rolled precision seamless steel tube (GB3639-2000) is used for precision mechanical structure, hydraulic equipment and high surface finish of cold drawn or cold-rolled precision seamless steel tubes.
Stainless steel seamless steel tubes and structure (GB/T14975-2002) is widely used in chemical, petroleum, hot-rolled stainless steel made of textile, medical, food, machinery and other industrial anti-corrosion pipes and structural parts and parts of the (extrusion, expansion) and cold drawing (rolling) seamless steel tube.
Stainless steel seamless tubes for fluid delivery network (GB/T14976-2002) is used for the transmission fluid made of stainless steel hot-rolled (extrusion, expansion) and cold drawing (rolling) seamless steel tube.
Development of seamless steel tube is in addition to general tube other than the section shape of seamless steel tube. According to the different shapes and sizes of steel pipe section can be divided into equal wall thickness special-shaped seamless steel pipe (code named D), unequal wall thickness special-shaped seamless steel pipe (code named BD), variable diameter special-shaped seamless steel pipe (code named BJ). Shaped seamless steel pipe widely used in various structural parts, tools and machinery parts. Compared with the circular tube, the special-shaped tube generally has larger inertia moment and section modulus, and has larger bending torsion resistance ability, can greatly reduce the structural weight, save steel.
