Seamless steel pipe is a round, square, or rectangular steel with a hollow section and no seams around it. Seamless steel pipes are made of steel ingots or solid tube blanks that are perforated into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Seamless steel pipe has a hollow section and is widely used as a pipe for conveying fluid. Compared with solid steel such as round steel, it is lighter in weight when it has the same flexural and torsional strength, and is an economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in building construction.
Precision steel pipe
Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Because the precision steel pipe has the characteristics of no oxidation layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation when cold bending, flaring, flattening and no cracks, etc. Therefore, products mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless pipes or welded tubes. The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
The characteristics of precision steel pipe
(1) High precision, which saves the loss of machining materials for users.
(2) There are many specifications and a wide range of applications.
(3) The cold-rolled finished product has high precision, good surface quality and good straightness.
(4) The inner diameter of the steel pipe can be made into a hexagonal shape.
(5) The performance of the steel pipe is superior, and the metal is denser.
While inheriting the advantages of seamless steel pipes, precision steel pipes also have some of their own characteristics. Manufacturing ring parts with precision can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sets, etc., which have been widely manufactured with precision steel pipes. The promotion and application of precision seamless pipes is of great significance to saving steel, improving processing efficiency, and reducing processing procedures or equipment investment. It can save costs and processing man-hours, increase production capacity and material utilization, and at the same time help improve product quality and reduce costs, which is of great significance to improving economic benefits. Generally, precision seamless tubes are used in industries that require high precision, and seamless tubes are mostly used in industries without precision requirements. After all, the price of precision seamless tubes of the same specification is higher than that of seamless tubes.
The difference between precision steel pipe and seamless steel pipe
1. The difference in appearance
(1) The main feature of seamless steel pipe is that it has no welded seam and can withstand greater pressure. Products can be very rough as cast or cold drawn.
(2) Precision steel pipe is a product that has appeared in recent years, mainly because the dimensions of the inner hole and outer wall have strict tolerances and roughness.
2. The difference in process
The production process of precision steel pipes is the same as that of ordinary seamless pipes, and there are more post-pickling and cold-rolling procedures than seamless pipes.
