IBC (Tianjin) Industrial Co.,Ltd is a leading 6-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 (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip/Coil and can be manufactured 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.

Packing of 6-ERW Steel Pipe:
Plastic plugs in both ends; Hexagonal bundles of max. 2,000kg with several steel strips; Two tags on each bundle; Wrapped in waterproof paper; PVC sleeve, and sackcloth with several steel strips, Plastic caps.
Test of 6-inch ERW Steel Pipe:
- Chemical Component Analysis,
- Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation),
- Technical Properties (Flattening Test, Bending Test, Hardness Test, Impact Test),
- Exterior Size Inspection,
- Hydrostatic Test,
- NDT TEST ( ET TEST, RT TEST, UT TEST)
ERW Pipe Manufacturering Process:
The skin effect and proximity effect of high-frequency current used to heat and melt the edge of the pipe blank. Pressure welding is carried out under the action of a squeeze roller. Realize production. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment, but their general strength is lower than seamless steel pipes.
6-inch ERW Steel Pipe, we could describe it in another way. 6-inch equal to 168.3mm. So in another way, we could call it 168.3 mm ERW Steel Pipe. And ERW Steel Pipe could ranging from 26.7mm to 609.6mm.
Common sizes for ERW Steel Pipe range from 1-inch OD to 24-inch OD in a variety of lengths to over 100 feet. Surface finishes available in bare and coated formats and processing can handle 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.
