Boiler High Pressure Carbon Steel Pipe ASTM A106 Grade C 56'' 1422mm X 120mm Size
TIPTOP piercing and rolling technology possesses a number of patents in designing and manufacturing the equipment, and has improved in lots of areas targeting better performance and efficiency, which has distinguished itself from its peers.
-Stable, fast and continuous
-Flexible on non-standard sizes
-Swift tooling switching
-Uniform mechanical properties and dimensions in longitudinal & transverse directions
-Better surface conditon thanks to shorter rolling time & good tooling quality
-Three-roller / five racks sizing machine can avoid inner hexagon significantly
