Product Description
EN10305-2 E355 OD12 Improved Surface Welded Steel Tube, Cold Drawn Steel Tube For Camshaft
Description: Cold drawn welded pipe is an excellent choice for manufacturing multistage hydraulic cylinder tubes. The process and precision match that of seamless steel tube cold drawing, utilizing precision resistance welding (ERW) followed by precision drawing to manufacture EN 10305-2 EU mechanical cold drawn steel tube welding standards.

Manufacturing Process
According to EN10305-2 standard, cold drawing on ERW tubes produces tubes with high strength, high quality, and seamless characteristics.
The cold rolled welded tube is produced by drawing ERW (electric resistance welded tube). During this process, sizing (wall thickness, inside and outside diameter), weld integrity, and surface finish are closely controlled to produce tube of the required size and mechanical property characteristics.
