ERW carbon steel pipe manufacturer

As a leading supplier of carbon steel pipe fitting, Beijing Metleader Pipeline Technology Inc. was established in 1982 and is a well-known manufacturer, trader, and supplier of carbon steel equal tee. Recently we exported a batch of carbon steel tee to South Africa for the application of an oil pipeline. The quality has been confirmed by the customer, they are planning to explore another end user. So in 2018, the purchasing quantity will be increased accordingly.

Shashwat Stainless Inc. is one of the best ERW Pipe Manufacturers in Nashik. A53 ERW Pipes are one of our most popular products in the Metal Market. ERW Steel Pipe is available in a variety of sizes, shapes, and dimensions, and can also be customized to meet our customers’ specific requirements.

Steel Pipes manufacturers Export a huge range of ERW Galvanized Steel Tubes & Steel Pipes

For pipes or tubes size 4 inch (10.2mm) OD and below, the strip is fed into a set of forming rolls which consist of horizontal and vertical rollers so placed gradually from the flat strip into 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.
The copper disk electrodes make contact on each side of the seam and the temperature is raised to the welding point. The outside flash is removed by a cutting tool as the tube leaves the electrodes, inside flash is removed either by an air hammer or by passing a mandrel through the welded tube after the tube has been cooled. This is termed Electric Resistance Welded or ERW tube/pipe.

High-frequency straight seam electric-resistance welded steel pipe (erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.
High-frequency resistance welding steel pipe, welding pipe, and ordinary welding process are not the same, the weld is made of the base metal melt from the body, and the mechanical strength is better than the general pipe. Smooth appearance, high precision, low-cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high-frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.
