Cold Drawn steel tube technology introduce

Cold drawn steel tube technology is more and more important for us to focus on, this technology has been widely used at present, to promote the development of the industry as a whole and its specific advantages are obvious, the cold drawn technology improved the efficiency of the whole, and brought convenience to many construction fields.

We summarized following Technical advantages of cold-drawn steel pipe:

1. Firstly the precision steel tube production efficiency has improved: under the traditional production method to produce 420 mm inner diameter, the 12-meter long cylinder that should cost 154 hours, and the cold drawing method only spend 4 minutes to finish. It is very important for our manufacturer to save the use of steel material, improve the processing efficiency, save energy and reduce the hydraulic cylinder, so the investment of the cylinder block processing equipment is very important for us.

2.Secondly High positive rate: the guiding role of rolling head in the cutting process, due to the deflection of the pipe by the self-weight deflection, resulting in the deviation of rolling head and boring tool, resulting in waste. The positive rate can only reach about 60%, and the use of cold-drawn production methods can be as high as 95% or more.

3.Thirdly Precious metal utilization: the traditional drilling method of manufacturing cylinder, the utilization rate of metal is only 50-70%. As the drawing method of production, metal is not only cut into iron, but it can be extended 30%, and the utilization rate of metal can reach 95%.

4.Last but not least Improvement of mechanical properties: the use of drawing method enables the blank to obtain more than 30% plastic deformation, due to the improvement of the working hardening and the limit of metal strength of finished tube. General in the finished tube in the ultimate strength increased by 60%, and high precision cold drawn pipe is seamless hot-rolled steel pipe, as the blank of the straight seam welded steel pipe, cold drawing machine after a special chemical treatment, through the special deformation of mould design drawing production high precision tube.

Our changzhou Ray steel tube main products is seamless precision tubes with wide usage. Our factory cover an area of more than 20000 square meters, and more than one hundred employees. Meanwhile we have sophisticated machining equipment, strong technical strength and advanced technology and so on.If you have any questions about steel tube, contact me.
