Manufacturing Process of Cold Drawn Seamless E355 Tube


The quality of a cold drawn seamless E355 tube largely depends on the manufacturing process. Every stage is carefully controlled to ensure compliance with EN 10305-1 requirements.

Step 1: Raw Material Selection

High-quality carbon steel billets are selected and inspected before production begins.

Step 2: Seamless Tube Formation

The billet is pierced and elongated to create a hollow seamless tube.

Step 3: Cold Drawing Process

The tube undergoes cold drawing through precision dies to achieve tighter tolerances and improved mechanical properties.

Step 4: Heat Treatment

Depending on customer requirements, the tubes may be normalized, stress-relieved, or annealed to achieve the desired mechanical performance.

Step 5: Straightening and Finishing

The tubes are straightened, cut to length, and finished to ensure precise dimensions.

Step 6: Inspection and Testing

Comprehensive testing verifies dimensional accuracy, mechanical properties, and surface quality.
