The raw materials of the same width of the API 5L black steel pipe can be processed in different molding angles to manufacture steel pipe in various diameters which are in accordance with the standards. The API 5L black steel pipe is extensively used in transferring corrosive matters such as petroleum and natural gas. Based on the customers requirements we can manufacture erw pipes and tubes of different size and shape. We have a very large production capacity of erw pipes and tubes. ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.

ERW pipe is available in lengths from single random to 120 feet depending on mill capability. ERW pipeis available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish are available in black or bare, or with protective coatings.
The pipe internal stress is very small and uniformly distributed after the full- length expansion. The corrosion and cracking of the pipe owing to stress can be effectively prevented. The application of welding on site is very easy because of the high dimension precision; The inside and outside welding are performed after the tack welding , so the welding process is very stable with good weld quality; The NDT is easy to perform on the weld during production and field operation as well; The length of the weld is shorter than that of the non-longitudinal seam pipe, so the probability of defects occurrence is very low; The coverage of the pipe specification is very wide. The pipe can be either in large diameter with thick wall or in small diameter with thick wall. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.

Resistance welded steel pipe (ERW steel pipe)is a collectively, straight seam high frequency resistance welding pipe (Electric Resistance Welding, referred to asOf ERW) ERW are the corresponding first letter of the English word. Resistance welded steel pipe welded steel pipe, AC and DC welding two steelForms. AC welding according to the different frequencies are divided into low-frequency welding, frequency welding, ultra-high frequency welding and soldering. High frequency welding is mainly used for thin-walled steel pipe. Pipe wall thickness or normal production of high-frequency welding is divided into contact welding and induction welding.DC welding is generally used for small diameter pipe. So, overall speaking, included in the high-frequency ERW pipe in pipe, is a high frequency welding ERW pipe production.ERWLongitudinal field of oil and gas storage and transportation of performance art, quality leadership, more economical steel. 2.SAW steel SAW steel pipe full name of Submerged Arc Welding Steel Pipe SAW steel pipe it is a manufacturing process using submerged arc welding of steel, the process generates very high current density, flux layer to prevent the rapid dissipation of heat, and concentrated inwelding area.Submerged arc weld of high quality, high efficiency, very little dust-free arc and the characteristics of submerged arc welded pipe used in pressure vessels, pipe manufacture, beams, low-pressure fluid, steel works.
