DIN1626 precision steel pipe has the advantages of high dimensional precision, high surface finish and no deformation under cold pressure. It can also withstand high pressure, can make a variety of complex deformation and mechanical deep processing.The thickness of DIN1626 precision steel pipe is generally 0.5mm-30mm, and the outer diameter is 2mm-180mm.
1、Characteristics of DIN1626 precision steel pipe
（1). DIN1626 precision steel pipe tolerance size precision is high. Product precision control is ±5mm. Inner and outer wall finish is good, no oxide layer on the surface.
(2). It has excellent comprehensive performance, and can withstand high pressure, cold bending, flaring, flattening, no cracking, no wrinkling. It can do all kinds of complex deformation and mechanical processing.
2.Processes of precision steel pipe
Cold drawing and hot rolling are two different processes used in most precision steel pipes. Relatively speaking, the technology of cold drawing is more complex, because it not only needs to carry out three-roll rolling, but also must carry out sizing test after extrusion, so as to better ensure the quality of precision pipeline materials. Precision steel pipes made with excellent technology are very good both in quality and appearance.
3、Applications of DIN1626 precision steel pipe
The inner and outer diameter of DIN1626 precision steel pipe can be accurate to less than 0.2mm. It is light in weight while ensuring the same bending and torsional strength, so it is widely used in manufacturing precision mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, gun barrels, bearings, etc
4、The promotion of precision steel pipe
The promotion of precision pipe can save steel, improve processing efficiency, reduce processing procedures and equipment investment. At the same time, it can also save costs and greatly save machining hours, improve production and material utilization rate, and help to improve product quality and reduce costs.
