Product Overview
Huayang 323.9 mm ERW steel pipe uses API 5L PSL1 Grade B steel for structural applications requiring consistent dimensions and reliable welded performance.
| Parameter | Specification |
|---|---|
| Outside Diameter | 323.9 mm |
| Material Grade | API 5L Grade B |
| Product Specification Level | PSL1 |
| Manufacturing Process | ERW |
| Welding Method | High-Frequency Welding |
| Main Application | Structural Steel Pipe |
The 323.9 mm outside diameter corresponds to DN300 and provides a practical large-size configuration for structural and engineering applications.
API 5L Grade B Material Performance
API 5L PSL1 Grade B has a minimum yield strength of 245 MPa and minimum tensile strength of 415 MPa. The grade offers a balanced combination of strength, weldability and dimensional stability for conventional engineering applications. ERW production forms steel strip into a circular section and uses high-frequency welding to produce a continuous longitudinal seam, supporting efficient production and consistent dimensional accuracy. Huayang's ERW production covers Grade B and includes chemical composition, mechanical property, hydraulic, X-ray and ultrasonic testing according to applicable requirements. When used as a structural steel pipe, the project design should confirm that API 5L Grade B meets the required structural design standard and load conditions.

Pipe Protection
Pipe-end protection is advisable in case the pipe-ends are bevelled at the pipe manufacturer. In the case of overseas transport, there is an especially increased risk of damaged pipe-ends. This is caused by extra handling procedures in ports and shifting of the pipes onboard vessels.
In addition to end caps or protective rings, external wrapping with protective cloth can be applied along the pipe body. This wrapping helps to safeguard the coating surface from scratches, moisture, and contamination during long-distance transportation or prolonged outdoor storage. Especially for coated or painted pipes, the additional protective cloth layer significantly reduces the risk of mechanical damage, UV exposure, and corrosion initiation, ensuring the pipes arrive at the destination in optimal condition.
