Product Description

Product Introduction

The cold working methods of steel pipes mainly include cold drawing and cold rolling.   The raw materials of cold-rolled steel pipes can be hot-rolled seamless steel pipes or welded pipes. The common characteristics of the cold working method of steel pipes are high dimensional accuracy and good surface roughness. It can produce very thin (up to 0.05~0.01mm) thin-walled tubes and very thin (up to 0.3~0.1 mm in diameter) capillaries.

Seamless steel pipe is a kind of pipe with hollow section, which is widely used to transport fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is light in weight when its bending and torsional strength is the same. It is a kind of economic section steel, which is widely used in pipeline engineering.
Generally, the production process of seamless steel pipe can be divided into cold rolling and hot rolling. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe. The wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe. But the surface looks brighter than that of thick wall seamless steel pipe. The surface is not too rough, and the diameter is not too much burr.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of the two methods must be used.
High precision cold drawn precision steel pipe is a new type of steel pipe, which is mainly characterized by high precision. There are usually two production processes of two high mill and three high mill. The precision of three high mill in producing cold rolled seamless steel pipe is higher, which can be controlled within a few wires, but the price is relatively higher.
The product specification range of cold rolled steel pipe is: outer diameter 4.0 ~ 450mm; The wall thickness is 0.04 ~ 60mm. Compared with the cold drawing method, the advantage of the periodic cold rolling method is that the shrinkage of the pass surface is large, there is no need for difficult head, and the yield is high.
