Product Overview
Huayang 508 × 11.9 mm LSAW steel pipe is manufactured from high-strength L415 pipeline steel, providing reliable strength and weld performance.
| Parameter | Specification |
|---|---|
| Outside Diameter | 508 mm |
| Wall Thickness | 11.9 mm |
| Material Grade | L415 |
| Manufacturing Process | LSAW |
| Welding Method | Double Submerged Arc Welding |
| Main Application | Oil and Gas Transmission |
The 508 mm diameter and 11.9 mm wall thickness provide a balanced configuration for medium-to-large transmission pipelines requiring controlled dimensional accuracy and structural reliability.
L415 Material Performance
L415 is a high-strength pipeline steel grade under the GB/T 9711 system, with a specified minimum yield strength of approximately 415 MPa. It provides higher strength than L360 and is suitable for transmission systems where increased pressure resistance and structural performance are required. Huayang's LSAW production uses steel plate forming followed by double-sided submerged arc welding, with dimensional inspection, ultrasonic testing, radiographic examination and hydrostatic testing available according to applicable project specifications. L415 can also be supplied with external anti-corrosion coatings such as 3PE or FBE when required for long-term pipeline service.

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.
