1. Automatic operation; 2. Short pieriod; 3. Low investment. AdvantagesSink tube end with a good consistency to improve the yield;Sink tube end looks like the neck of a bottle, with a smooth surface; meanwhile, the slope part can be drawn without leaving 20mm-30mm during crop...

High precision to increase the linearity and the roundness of a pipe/tube. Straightening machine is used to straight steel pipe and rod of black metal and non-ferrous metal. When pipe\rod is fed into the machine, the hyperbolic curved straightening rollers makes the straightened...

Low investment High efficiency Wide pipe size: the thinckness range is wide, bigger extend coefficient     Purpose: Let the mandril of the Continuous Tube Mill in the crude pipe which came from the piercer machine, the three frames are arranged in order and the...

Billet material: Alloy structure steel, stainless steel Billet size: diameter240~400, lengh1500~4500Crude pipe size: diameter250~440, thickness20~60, length3500~10000Jan 18th, 2011, we have successfully complete the trial run in a manufacture of China. It shows our technology step...

We are capable of producing various kinds of shell rolling mills ranging OD70 ~280mm. Shell rolling is the main deforming process in seamless pipe production. It aims to clear up longitudinal uneven wall thickness occurred during piercing and make the wall thickness close to or...

1. Low investment and high productivity 2. Suitable for all kinds of metal piercing 3. High degree of automation Its roller is cone type, and roller diameter gradually becomes bigger from the direction of inlet to exit which is accordant with the increase of metal flow speed...

Low investment,; Simple structure; Easy operation. After sizing or reducing the temperature of pipe is generally above 700 °C. It must be cooled to below 150 °C for subsequent finishing process. The pipe cooling is usually carried out on cooling bed. Generally speaking,...

1. Low investment, easy operation 2. high fineness, low deflection Rated drawing force(KN) Rated drawing speed(m/min) Max length(m)Drawn-car returning speed(m/min) Motor  type        Motor...

Simple structure; Low investment; Effectively improve product quality; It has three main functions as following: 1. To reduce shell eccentricity and provide qualified shell for later process thus improving rate of acceptability; 2. To increase the tip head compression while...

Low investment; High efficiency; Wide product range. Sizing and reducing is the last hot deforming process of shell in seamless pipe production. After sizing\reducing process, shell becomes finished steel pipe of different specifications. Sizing-reducing mill can increase...
