Direct-forming Square Pipe Mill

WRD Advantages

Advanced Technology:
It adopts the multipoint bending combined type forming technology, which consists of forming and sizing section. All sizes need only one set of rolls. While manufacturing, the roll could be adjusted partly.

High Production Efficiency:
One set of mould can produce all size of square and rectangle pipe, so the time of adjusting the mould is shorter and the production is higher.

Lower Cost:
Cut down the cost of machine; Save more than 40% of roll.

Fast Payback:
Easy to operate and maintain. You can expect a typical return on investment minimum within 12-18 months.

Easy Operation:
The software and operator panel with easy user interface. Ability to change the production diameter by modifying the settings from computer without changing die.

Environmental Friendly:
Equips with acid mist absorption device, zinc dust collect device, solvent iron removal device, sewage & waste acid treatment system, no pollution emission.
