LG90H Cold Rolling Mill

4 Inch Drill Pipe Production Equipment Two Roll Mill

 

  Drill pipe is hollow, thin-walled, steel alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. Due to the deep depth of oil wells and bad working conditions, the mechanical properties, dimensional accuracy and straightness of drilling pipes are required to be higher.

 

Advantages of two roll mill

 

Two roll mill is an important equipment for oil well pipe producing. It has large diameter reduction and large wall reduction, during the rolling process, the mechanical properties of the material can be improved, and high-quality surface quality can be obtained. 

 

Features of our cold rolling die and mandrel

 

The roll pass shape of rolling die and mandrel determines the physical properties of the finished pipes. We have developed the special rolling grooves of die and mandrel to improve the straightness and tolerance of finised drill pipes, which improve the life of drill pipes greatly.
