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.
Overview
-
WRD designed and manufactured the directly forming square and rectangle pipe mill line is used to manufacture the welded pipe up to 500×500mm.
-
It adopts the multipoint bending combined type forming technology, which consists of forming and sizing segment, one set forming roll in the forming segment, while manufacturing, the roll could be adjusted partly, saving roll free more than 40%.
