API Pipe Mill

WRD Advantages

Outstanding Achievements:
More than 17 complete API pipe mills design, manufacture, install and commission by WRD and 6 lines of them are Turnkey projects supplied by WRD.

WRD Unique Technology:
● On line inner deburr for 1/2” steel pipes with 50 meters per minute.
● 3 inch pipe thickness could reach to 11.75 mm under API standard.

Quick-Change Technology:
Adopt mature roll combination technology and side outlet roll changing technology, which can greatly improve production efficiency and reduce the cost of production and 50% of rolls.

Optimized Forming Process:
Two forming ways supplied: WFF and WFFX 
Make full use of the free adjustable roll function to obtain the product quality that other mills cannot get.

Wide Range of Production:
Can produce pipes from 1/2” to 28” with high-grade material such as X80 and N80.

High-automatic:
From uncoiler to automatic packing machine, all equipment are high automated controlled. The operation is convenience, safety and reliability.

One-stop Solution:
WRD can also supplies various pipe finishing equipment such as End Facing, Threading, Hydro testing, Eddy Testing, Annealing, Auto painting, Auto Stacking, etc.

Customization:
Can be customized according to site space factors, raw materials, energy situation, product quality and capacity control requirements.

Overview

The “WFF” forming method has simple structure, convenient maintenance and high production efficiency. The rollers of the first four horizontal frames, the first and second vertical roller frames, and the third, fourth and fifth C-roll frames have commonality. The replacement specifications do not need to be replaced, only adjustment is required. Save 30% of the entire set of equipment rolls, save roll change time, improve production efficiency, and have a competitive advantage in the market competition. This molding method is the world's advanced technology, and the state of stress during the deformation process is more reasonable. Our company digested and absorbed on this theory, and applied this advanced molding technology to the unit, so that the unit reached the domestic advanced level.

The "WFFX" forming method is especially suitable for the API pipe lines, and the stress state is more reasonable during the deformation process, which can save 50% of the roll. Based on this theory, our company is able to absorb this advanced molding technology into this unit, so that the unit can reach the international advanced technology level.

The production line adopts the mature, reliable, complete, economic applicable advanced technology, advanced equipment, to ensure product quality, cost, and the consumption indexes reach the advanced level, products have strong competitiveness in quality and price.
