Product Overview
As a professional China welded steel tube manufacturer, we supply E195 Cold Drawn Welded Steel Tubes, also known as DOM (Drawn Over Mandrel) tubing. These welded carbon steel tubes are further cold drawn to improve dimensional precision, mechanical strength, concentricity, and surface smoothness—ideal for automotive parts, machinery, and hydraulic applications. Compared with standard welded pipes, cold drawn welded tubes offer significantly better dimensional tolerance and superior tensile properties, making them a reliable solution for structural and pressure-bearing use.

FAQ
Q1: Are you a China welded steel tube manufacturer or trader?
A: We are a direct manufacturer with full ERW welding and cold drawing capabilities. Our factory is located in Changzhou, Jiangsu Province.
Q2: What’s the difference between ERW and cold drawn DOM tubing?
A: ERW tubes are welded from strip steel. Cold drawn DOM tubing is ERW tube further processed through cold drawing, improving mechanical strength and precision.
Q3: Can I order small quantity for trial?
A: Yes, MOQ is 1 ton per size for standard grades.
Q4: How is the product packaged for overseas shipment?
A: Tubes are packed in bundles with oil coating and protective wrapping. Wooden cases can be added upon request.
