At Afra Zomorod Asia, we produce high-quality Cold Drawn Welded (CEW) tubes using advanced technology. These welded, cold-drawn tubes are renowned for their exceptional dimensional accuracy, superior surface finish, high tensile properties, and availability in non-standard sizes, making them ideal for hydraulic, automotive, oil, and gas industries. CEW tubes are manufactured from Electric Resistance Welded (ERW) tubes as the base material. The production process involves precise steps, including annealing, pickling, phosphating, lubrication, grinding, and cold drawing. These steps ensure the unmatched strength and precision of our precision and cylindrical tubes. Choose Afra Zomorod Asia’s CEW tubes for performance that meets global standards (ASTM, DIN, API) and long-lasting durability. Explore our products or contact our team for more details.
Precision TubesIndustrial Applications
Afra Zomorod CEW tubes are often used in the automotive industry due to their strength, durability, and resistance to deformation under high stress. Here are a few examples of automotive components that may use CEW tubes:
Steering Box
Shock Absorber
Gas Spring
FullyIntegrated Production
ASIA Tube is most proud of its integrated production control system covering tube manufacturing, drawing, heat treatment, and cutting. Whereas many tube manufacturers outsource the drawing process, this is yet another area where we exhibit our user-focused characteristics and commitment.

DrawProcess Steps
This process involves pulling a steel rod or bar through a die at room temperature to produce a tube with a precise diameter and wall thickness. Here are the key steps involved in the cold drawn tube manufacturing process:
Forming
Rollers with various curvatures are used to bend flat steel strip into a tubular shape.
Electric Resistance Welding
A high frequency induced current is used to hot pressure weld the edges of the steel strip formed into a tubular shape.
Eddy current Testing
The integrity of the raw material and weld zone is completely inspected online in a non-destructive means.
Sizing
Rollers with various curvatures are used to squeeze the welded tube, adjusting its outer diameter. Rectangular or square tube can be formed in addition to round tubes.
Cutting
Cutters are used to cut the continuously formed tube into defined lengths.
Heat Treatment
The metallic structure of the high frequency electric resistance welded tube is standardized and softened through heat treatment in a continuous furnace.
Surface Treatment
The surface is roughened through pickling and the tube is put through chemical treatment and dipped in oil.
Swaging
The end of the tube is swaged, reducing the outer diameter so that it can be inserted into the dies for cold drawing.
Cold Drawing
The tube is drawn through plug dies, creating steel tube with excellent dimensional accuracy and smoothness.
Straightening
The straightness of the tube is increased.
