Carbon Steel Pipe Fittings Can Greatly Reduce The Weight Of The Structure, Saving Steel
Jun 09, 2017

Classification of a pipe

1, according to the production method of classification

(1) seamless pipe - hot-rolled pipe, cold-rolled tube, cold-drawn tube, extrusion pipe, pipe jacking (2) pipe (a) by the process points - arc welded pipe, resistance welded pipe (high frequency,Carbon Steel Pipe Fittings Gas pipe, furnace welded pipe (b) by seam sub - straight seam welded pipe, spiral welded pipe

2, according to cross-sectional shape classification

(1) Simple cross-section steel pipe - round steel pipe, square steel pipe, oval steel pipe, triangular steel pipe, hexagonal steel pipe, diamond-shaped steel pipe, octagonal steel pipe, semi-circular steel round, other (2) Side hexagonal steel pipe, five plum-shaped steel pipe, double convex steel pipe,Carbon Steel Pipe Fittings double concave steel pipe, melon-shaped steel pipe, conical steel pipe, corrugated steel pipe, case steel pipe, other

3, by wall thickness classification - thin-walled steel pipe ⒑

4, according to the use of classification - pipe with steel, thermal equipment with steel, machinery industry with steel, oil, geological drilling steel pipe, container steel pipe, chemical industry steel pipe, special purpose steel pipe, other

Second, seamless steel pipe

Is a hollow section, the surrounding no seam of the long steel. The steel pipe has a hollow section, a large number of pipes used to transport fluid, such as the transmission of oil, natural gas, gas, water and some solid materials such as pipeline. Steel and round steel and other solid steel compared to the same bending strength, the weight is light, is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle Racks and steel scaffolds for construction purposes. The use of steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, saving materials and processing time, such as rolling bearing rings, jack sets, etc.,Carbon Steel Pipe Fittings has been widely used to manufacture steel. Steel pipe or a variety of conventional weapons indispensable materials, barrels, barrels and so on to steel to manufacture. Steel pipe by cross-sectional area of the shape can be divided into tube and shaped tube. As the circumference of the same conditions, the largest circular area, with a circular tube can transport more fluid. In addition, the ring cross section in the internal or external radial pressure, the force is more uniform, so the vast majority of steel pipe is a tube. However, the tube also has some limitations, such as in the plane under the conditions of bending, the tube is not as good as the square tube bending strength, some agricultural machinery skeleton,Carbon Steel Pipe Fittings steel and wood furniture on the commonly used side, rectangular tube. According to different purposes need to have other cross-shaped shaped steel pipe.

Seamless steel pipe for structural use is a seamless steel pipe for general construction and mechanical construction.

2. Seamless steel pipe for fluid delivery  is a general seamless steel pipe for conveying water, oil and gas.

3. Low and medium pressure boiler seamless steel pipe is used to manufacture a variety of low and medium pressure boiler superheated steam pipe, boiling water pipe and locomotive boiler with superheated steam pipe, large smoke pipe, small smoke pipe and arch Pipe with high quality carbon structural steel hot rolling and cold drawing (rolling) seamless steel pipe.

4. High-pressure boiler seamless steel pipe is used to manufacture high pressure and above the pressure of the water pipe boiler heating surface with high-quality carbon steel,Carbon Steel Pipe Fittings alloy steel and stainless steel heat-resistant steel seamless steel pipe.

5. High-pressure seamless steel pipe for chemical fertilizer equipment is suitable for working temperature of -40 ~ 400 ℃, the working pressure of 10 ~ 30ma of chemical equipment and pipeline of high-quality carbon structural steel and alloy steel seamless steel pipe.

6. Seamless steel pipe for oil cracking is applicable to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe.

7. Geological drilling steel pipe is for the geological sector for the use of core drilling steel pipe, according to the use can be divided into drill pipe, drill collar, core tube, casing and sedimentation tube.

8. Diamond core drilling seamless steel pipe is used for diamond core drilling drill pipe, core rod, casing seamless steel pipe.

9. Oil drilling pipe is used for oil drilling at both ends of the thickening or thickening of the seamless steel pipe. The steel pipe is divided into two kinds of wire and no wire, and the wire tube is connected with the joint.

10. Carbon steel seamless steel pipe is a manufacturer of ship-class pressure-resistant pipe system, ⅱ grade pressure pipe system, boiler and superheater with carbon steel seamless steel pipe. Carbon steel seamless steel pipe wall temperature does not exceed 450 ℃, alloy steel seamless pipe wall temperature of more than 450 ℃.

11. Automotive semi-axle casing with seamless steel pipe is the manufacture of automotive axle casing and axle axle axle with high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe.

12. High-pressure tubing for diesel engines is a cold-drawn seamless steel pipe for the manufacture of high-pressure pipes for diesel engine injection systems.

13. Hydraulic and pneumatic cylinder with precision diameter seamless steel pipe is the manufacture of hydraulic and pneumatic cylinder with precision diameter of the cold drawn or cold rolled precision seamless steel pipe.

14. Cold drawn or cold rolled precision seamless steel pipe is used for mechanical structure, hydraulic equipment, high dimensional accuracy and good surface finish cold drawn or cold rolled precision seamless steel pipe. Selection of precision seamless steel pipe manufacturing machinery or hydraulic equipment, can greatly save the mechanical processing hours,Carbon Steel Pipe Fittings improve material utilization, while helping to improve product quality.

15. Structural stainless steel seamless steel pipe is widely used in chemical, petroleum, textile, medical, food, machinery and other industries of corrosion-resistant pipes and structural parts and parts made of stainless steel hot- Extruded, expanded) and cold drawn (rolled) seamless steel tubes.

16. Stainless steel seamless pipe for fluid delivery  is a hot-rolled (extruded) and cold drawn (rolled) seamless steel pipe made of stainless steel for conveying fluids.

17. Shaped seamless steel pipe is in addition to the tube other than the cross-sectional shape of the general name of the seamless steel pipe. According to the different shape and size of the steel pipe can be divided into different thickness of special-shaped seamless steel pipe (code d),Carbon Steel Pipe Fittings different thickness of seamless steel pipe (code-named bd), variable diameter shaped seamless steel pipe (code bj). Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. Compared with the tube, the special-shaped tube generally have a larger moment of inertia and cross-section modulus, a greater bending and torsion ability, can greatly reduce the weight of the structure, saving steel.
