About MS CEW TUBE 38mm OD X 3mm/4mm/5mm Thickness

*Cold Extended Welded (CEW) tubes, also known as CDW (Cold Drawn Welded), are high-precision steel tubes manufactured through a meticulous cold-drawing process. Starting as electric resistance welded (ERW) tubes, they are pulled through a die and over a mandrel at room temperature. This process significantly enhances the tubea s mechanical properties, resulting in superior dimensional accuracy, a high-quality surface finish, and increased tensile strength. Because the drawing process eliminates the internal weld bead, CEW tubes offer exceptional concentricity and uniformity. They are the preferred choice for demanding industrial applications such as hydraulic cylinders, shock absorbers, automotive axles, and precision engineering components where tight tolerances and durability are non-negotiable.

Key Characteristics

Manufacturing Process: Starts as a standard ERW tube, then cold-drawn at room temperature to achieve exact wall thicknesses and diameters.
Superior Weld Strength: Cold drawing improves the weld seam, allowing it to reach >95% of the parent material's strength.
Precision: Offers high dimensional accuracy and exceptional surface finish, often reducing the need for costly secondary machining.
Typical Specifications

Standards: Commonly manufactured to specifications like IS 3074 (specifically grades CEW 1 through CEW 5 for automotive purposes).
Size Range: Outer diameters generally range from 6 mm to 114.3 mm, with wall thicknesses varying between 0.5 mm and 20 mm.
Length: Standard lengths are usually 6 meters, or custom-cut to specification.

Common Applications

Automotive: Used for shock absorbers, steering columns, exhaust systems, and structural components.
Industrial & Machinery: Hydraulic equipment, material handling devices, and precision machined parts.
