1-inch ERW Steel Pipe

1-inch ERW Steel Pipe Manufacturer

IBC (Tianjin) Industrial Co.,Ltd is a leading 1-inch ERW steel pipe manufacturer from China. We could supply whole range of ERW steel pipes from 1/2-inch to 24-inch. Straight seam high frequency welded pipe (ERW steel pipe) is formed by forming a hot-rolled coil through a forming machine. ERW short for Electric Resistance Welded pipes. Its welded seam is longitudinally. It manufactures from Strip/Coil and can up to 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.

ERW Pipe Manufacturering Process

In order to achieve the skin effect and proximity effect, high-frequency current is used to heat and melt the pipe blank edge and apply pressure using a squeeze roller. The steel pipes that are welded are simpler to manufacture, more efficient, have a wide variety and specifications, and require less equipment, but their general strength is lower than seamless steel pipes. In another way, we could call it 33.4mm ERW Steel Pipe. And ERW Steel Pipe ranges from 21.6mm to 609.6mm, and 1-inch equals 33.4mm. ERW Steel Pipe is available in several sizes from 1/2-inch OD to 24-inch OD in a variety of lengths up to 100 feet. Surface finishes can be either bare or coated, and processing can be done on-site to customer specifications.

It mainly used for low/ medium pressure applications such as transportation of water / oil. IBC Metal Group is one of the leading ERW Steel Pipes Manufacturer and exporter from China. Contact us for product details.
