3.Stainless Steel Composite Welded Pipe Mill

The stainless steel composite welded pipe unit is divided into two models according to the state of the steel plate. Thin-walled and narrow-width steel coils are produced continuously, and thick-walled and wide-width single steel plates are produced by intermittent production. In general, continuous production models are used for diameters below 325mm and wall thicknesses below 10mm, while intermittent production models are used for diameters of 325-914mm and wall thicknesses of 10-25mm.

The continuous production model is to open the steel coil for leveling, mill the bevel online, transform the steel strip into a round tube embryo through a forming machine, and then weld it into a stainless steel composite steel pipe through several welding passes.

The intermittent production model is to flatten and mill the single-sheet bimetallic steel plate after metallurgical compounding, and then enter the forming machine, use the single-sheet forming unit, and bend the compound steel plate into a circular tube through the physical action of the rollers. Then use our company’s patented welding device to weld the steel pipe.

Our company’s fully automatic precision control flexible molding technology, all molding machines do not need to replace rolls, which greatly reduces the investment.

4.LSAW Pipe Mill

The LSAW pipe mill is the latest unit developed by our company. This unit uses steel coils as raw materials to produce thick-walled high-strength straight-seam submerged arc steel pipes. The steel pipe produced by the LSAW pipe unit overcomes the disadvantages of uncontrollable weld quality, which is inferior to submerged arc welding and high energy consumption, overcomes the weld length of spiral welded pipe and unsuitable inspection after the weld is buried, and overcomes UOE and JCOE the disadvantages of huge investment and high production cost. The weld quality of LSAW pipe is the best among all welding processes, and it is also the most reliable, easy to detect, maintain and repair. The steel pipe produced by this unit covers most of the specifications used in the current oil and gas pipelines, and has a good market prospect.

1. Round Tube Mill Without Changing Rolls

The round tube mill without changing rolls is the latest product developed by our company. When changing product specifications, all forming machines do not need to replace rolls and the precision forming racks that previously needed to replace rolls do not need to be replaced. This saves a lot of investment and is especially suitable for medium and large-scale pipe mills.

When changing product specifications, the adjustment of the rolls is also fully automated. Just input the pipe diameter, wall thickness, material and other parameters on the industrial computer, and all the rolls will be automatically adjusted to the appropriate position and directly start production. This saves a lot of time, makes multi-variety and small-batch order production possible, increases the operating rate of the unit, and improves the operating rate of the unit. And the automatic computer adjustment can reduce the error of manual adjustment, improve the yield of the unit, and increase economic benefits.

2.Round to Square Pipe Mill Without Changing Rolls

The round to square pipe mill without changing rolls is the latest product developed by our company. When changing product specifications, all forming machines do not need to replace rolls and the precision forming racks that previously needed to replace rolls do not need to be replaced. The sizing part is responsible for round and square. Our unit adopts the latest technology, and the sizing machine does not need to replace rolls. This saves a lot of investment and is especially suitable for medium and large-scale pipe mills. When changing product specifications, the adjustment of the rolls is also fully automated. Just input the pipe diameter, wall thickness, material and other parameters on the industrial computer, and all the rolls will be automatically adjusted to the appropriate position and directly start production. This saves a lot of time, makes multi-variety and small-batch order production possible, increases the operating rate of the unit, and improves the operating rate of the unit. And the automatic computer adjustment can reduce the error of manual adjustment, improve the yield of the unit, and increase economic benefits.

The production of square tubes is divided into two different processes, one is cold bending forming directly into a square, and the other is round to square. The products produced by the process of round to square have full rounded corners and a particularly beautiful appearance. Due to technical limitations, the previous unit had to replace a set of rolls for each specification, which required a large investment, and it was time-consuming and laborious to replace the specifications. Our company uses the latest technology to completely solve this problem. Our unit only needs to replace the welding roll, and all other rolls do not need to be replaced. In this way, large investment can be avoided, and high-quality square tube can be produced, which is the most economical square tube unit.

Φ102-Φ219*12mm ERW Pipe Mill Without Roller Changing

The Φ102-Φ219x12mm automatic ERW pipe mill without roller changing designed and manufactured by our company for Hengshui Jinghua Welded Pipe Company was successfully tested in April 2016. The ERW pipe mill without roller changing is the latest patented product developed by our company. When changing the product specifications, all the forming machine parts do not need to replace the rollers. In the past, the precision forming frame that needs to replace the rollers does not need to be replaced on our unit. Can save a lot of roll investment, especially suitable for large and medium-sized units. When changing the product specifications, the adjustment of the rolls is also fully automated. Simply input the parameters such as pipe diameter, wall thickness, and material on the industrial computer, and all the rolls will be automatically adjusted to the appropriate position, and the feed is directly turned on for production. This saves a lot of adjustment time when changing the model, making it possible to produce multiple varieties of small batch orders, increasing the operating rate of the unit and increasing the start-up rate of the unit. And the fully automatic computer type change can also make the adjustment accurate, reduce the error of manual adjustment, improve the yield of the unit, and increase the economic benefit of the unit.
