Precision seamless pipe is a kind of high-precision steel pipe material after seamless steel pipe is processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of the precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no cracks in flaring and flattening, etc. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when it has the same flexural and torsional strength. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts. The following is an introduction to the characteristics and uses of precision seamless pipes.
Production process of precision seamless pipe
Precision seamless pipes are usually produced by cold rolling. The specific process is as follows:
Tube blank--inspection--peeling--inspection--heating--perforation--pickling passivation--grinding--lubricating and air-drying--cold rolling--degreasing--cutting--inspection--marking- -Product packaging
Precision seamless pipe features
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
The difference between precision seamless pipe and ordinary seamless pipe
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 modern product, mainly because of the strict tolerance and roughness of the inner hole and outer wall.
What are the uses of precision seamless tubes
It is widely used in steel pipes for hydraulic systems, steel pipes for injection molding machines, steel pipes for hydraulic machines, steel pipes for shipbuilding, EVA foam hydraulic machinery, steel pipes for oil pressure cutting machines, shoemaking machinery, hydraulic equipment, high pressure oil pipes, hydraulic oil pipes, Ferrule joints, steel pipe joints, rubber machinery, forging machinery, die-casting machinery, construction machinery, high-pressure steel pipes for concrete pump vehicles, sanitation vehicles, automobile industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, air compressors , construction machinery, agricultural and forestry machinery, etc., can completely replace imported seamless steel pipes of the same standard.
Summarize
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, reducing processing procedures or equipment investment, saving costs and processing hours, and improving production capacity and material utilization. At the same time, it is beneficial to improve product quality, reduce costs, and 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.
