Classification and Application of Seamless Stainless Steel Pipes-Shangzhan stainless steel

The following are the extensive classified applications of stainless steel seamless steel tubes: 1. The stainless steel seamless steel tubes for structures (GB/T8162-1999) are seamless steel tubes for general and mechanical structures.2. Stainless steel seamless steel pipe for fluid transportation (GB/T8163-1999) is a general seamless steel pipe used to transport water, oil, gas and other fluids.3. Stainless steel seamless steel tubes for low and medium pressure boilers (GB3087-1999) are high quality carbon structural steel hot-rolled and cold-drawn seamless steel tubes for superheated steam pipes, boiling pipes and superheated steam pipes for locomotive boilers of various structures.4. Seamless steel pipes for high pressure boilers (GB5310-1995) are high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipes for heating surfaces of water-pipe boilers with high pressure and above.5. High-pressure stainless steel seamless steel pipe for fertilizer equipment (GB6479-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe for chemical equipment and pipeline with working temperature ranging from - 40 to 400 degrees C and working pressure ranging from 10 to 30 Ma.6. Stainless steel seamless steel tubes for petroleum cracking (GB9948-88) are seamless steel tubes for furnace tubes, heat exchangers and pipelines in petroleum refineries.7. The steel pipe for geological drilling (YB235-70) is used for core drilling by geological departments. It can be divided into drill pipe, drill collar, core pipe, casing and sedimentation pipe.8. Seamless steel pipe for diamond core drilling (GB3423-82) is a seamless steel pipe for drill pipe, core rod and casing used in diamond core drilling.9. Petroleum drilling pipe (YB528-65) is a seamless steel pipe used to thicken both ends of oil drilling.The steel pipe is divided into two kinds, namely, split wire and non-cut wire. The wire pipe is jointed by joints, and the non-cut wire pipe is joined by butt welding with tool joints.10. Carbon steel stainless steel seamless steel pipes for ships (GB5213-85) are carbon steel seamless steel pipes for manufacturing class I, class I I, boilers and superheaters.Carbon steel seamless steel pipe wall working temperature does not exceed 450 C, alloy steel seamless steel pipe wall working temperature exceeds 450 C.11. The stainless steel seamless steel tube for automobile half-axle sleeve (GB3088-82) is a hot-rolled seamless steel tube for automobile half-axle sleeve and driving axle housing.12. The high-pressure oil pipe for diesel engine (GB3093-2002) is a cold-drawn seamless steel pipe for manufacturing high-pressure pipe for diesel engine injection system.13. Precision inner diameter seamless steel tubes for hydraulic and pneumatic cylinders (GB8713-88) are cold-drawn or cold-rolled precise seamless steel tubes with precise inner diameter for hydraulic and pneumatic cylinders.14. Cold-drawn or cold-rolled precise seamless steel tubes (GB3639-2000) are cold-drawn or cold-rolled precise seamless steel tubes with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment.Choosing precise seamless steel pipe to manufacture mechanical structure or hydraulic equipment can greatly save processing time, improve material utilization rate and improve product quality.15. Stainless steel seamless steel tubes for structures (GB/T 14975-2002) are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel tubes made of stainless steel which are widely used in chemical, petroleum, textile, medical, food, machinery and other industries.16. Stainless steel seamless pipe for fluid conveying (GB/T14976-2002) is hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel pipe made of stainless steel for fluid conveying.17. Special-shaped seamless steel pipe is the general name of seamless steel pipe with other cross-section shapes besides circular pipe.According to the shape and size of steel tube cross section, it can be divided into iso-wall thickness special-shaped seamless steel tube (code D), unequal-wall thickness special-shaped seamless steel tube (code BD), and variable-diameter special-shaped seamless steel tube (code BJ).Special-shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts.Compared with circular pipe, special-shaped pipe generally has larger inertia moment and section modulus, has greater flexural and torsional resistance, can greatly reduce the weight of the structure and save the price of seamless steel pipe.
