Product Description

Product Description

Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high smoothness, no deformation during cold bending, flaring, flattening, and no cracks, they are mainly used to produce products for pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded joints.
1. Smaller outer diameter.
2. High precision for small batch production.
3. Cold drawn finished products have high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complex.
5. Steel pipes have superior performance and dense metal.

Import and export steel pipes

Generally, the import volume of seamless pipe is large. The main importing countries are Germany and Japan. European countries such as Romania, Russia, Switzerland, France, Spain, the Czech Republic, Yugoslavia, Hungary and other countries have imported. There are also a small amount of imports from Argentina, Mexico and other countries in South America.
According to the different requirements of the consumer in China, there are more than 100 types of imported seamless pipes, including 15922mm, 1595mm and 15918mm. 114.38mm,114.310mm,114.313mm. The length is generally 5-8m or 4-7m. Mainly hot-rolled carbon structure and ST65. The minimum diameter of the inlet specification is 305 mm, and the maximum diameter is 47813 mm.
A small number of seamless pipes with small diameter and thin wall have been imported from France and Spain, such as 183mm, 223mm, 26.93mm, etc. Implement the general rules of Mannesmann Steel Pipe Plant in Germany.
Seamless pipes imported from Hungary and Japan often refer to DIN2448 and DIN1629.

product application

It is a high-performance carburized steel with high hardenability. After carburizing and quenching, it has a hard and wear-resistant surface and a tough core, with high low-temperature impact toughness, moderate weldability, and good machinability after normalizing. Used for manufacturing important parts with a cross-sectional area of<30mm that withstand high-speed, medium or heavy loads, impacts, and friction, such as gears, gear rings, gear shaft crossheads, etc. It is a substitute steel of 18CrMnTi and is widely used as carburized parts. In the automobile and tractor industries, it is used as an important carburized part with a cross section of less than 30mm, which can withstand high speed, medium or heavy load, impact and friction, such as gear, shaft, gear ring, gear shaft, main shaft of sliding bearing, crosshead, Dog clutch, worm, etc.
