Our factory, Tianjin United Steel Pipe, has passed API certification of United States in 2007, including API 5CT and API 5L.

The manufacturing technique of ERW line pipe is longitudinally welded tube. The specification for this product is outer diameter 33.4- 609.6mm and wall thickness 2.1 - 14mm. For OD tolerance, temperature is kept around at room temperature in cold roll forming and straight seam high frequency resistance welding process, thus OD control is accurate and fluctuation range is small. Hot rolled steel coil is the raw material so it has precise wall thickness tolerance. With regard to surface condition, this product has smooth and uniform thickness and no scratches or pits.

Our company has advanced straight seam high frequency welded pipe mill, slitting equipment, online/offline nondestructive testing equipment, flat head chamfering machine, hydrostatic testing machine and supporting testing center.

Length of ERW line pipe can be customized according to customer requirements and length tolerance is controlled within the range of + /-20mm.

We are an ERW line pipe supplier in China. We offer a wide range of products, including square and rectangular hollow section, galvanized steel pipe, bolts and nuts, concrete nails, and more.
