Product Overview
Huayang 508 × 12.7 mm LSAW steel pipe uses API 5L PSL1 Grade B steel for reliable performance in conventional transmission pipeline systems.
| ParameterSpecification | |
| Outside Diameter | 508 mm |
| Wall Thickness | 12.7 mm |
| Material Grade | API 5L Grade B |
| Product Specification Level | PSL1 |
| Manufacturing Process | LSAW |
| Welding Method | Double Submerged Arc Welding |
| Main Application | Oil and Gas Transmission |
The 508 mm diameter and 12.7 mm wall thickness provide a balanced configuration for pipeline systems requiring dependable strength, weld integrity and dimensional stability.
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. It is a widely used line pipe grade offering a practical balance of strength, weldability and toughness for conventional oil, gas and water transmission applications. LSAW manufacturing is suitable for this diameter and wall thickness, using formed steel plate and double-sided submerged arc welding to achieve a stable longitudinal weld. Huayang can perform dimensional inspection, ultrasonic testing, radiographic examination and hydrostatic testing according to applicable API 5L and project requirements. API 5L Grade B can also be supplied with external anti-corrosion coatings such as 3PE or FBE when required.

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.
