1. Technical Superiorities and Features in Respect of Tube and Pipe Products

BERIS Engineering and Research Corporation was the first engineering company involved in the engineering of seamless tube and pipe production and is technically the most powerful company in China. The sole technical center for tubes in China is set up in BERIS. Technical superiorities are as follows:

To provide users with optimal technological scheme according to the industrial situations at home and abroad;

Rich experiences on technical integration, research and practical application of steel tube technology;

Complete capability in design and packaged supply of non-standard equipment for large-scale steel tube projects:

 Design conversion of various steel tube rolling mills and auxiliary facilities like sawing machine as well as design and supply of auxiliary facilities

Cooling Circulating System for Front Table, Rear Table and Mandrel of Cone Type Piercing Mill

 

Piercing and Rear Table

Mandrel rolling mill/ skew rolling mill, cold rolling and cold drawing and tube push bench

 

Rapid Cooling of Mandrel
