Product Overview
Huayang GOST 10704 Ст3 LSAW steel pipe is manufactured for industrial piping systems requiring consistent dimensions and reliable longitudinal welded performance.
| Parameter | Specification |
|---|---|
| Material Grade | Ст3 |
| Standard | GOST 10704 |
| Material Standard | GOST 380 |
| Manufacturing Process | LSAW |
| Welding Method | Double Submerged Arc Welding |
| Product Type | Longitudinally Welded Steel Pipe |
| Main Application | Industrial Piping Systems |
GOST 10704 establishes the dimensional range for straight-seam electrically welded steel pipe, while the applicable technical requirements refer to GOST 10705 and GOST 10706. Ст3 is one of the carbon steel grades specified for GOST 10704 products.
Ст3 Material Performance
Ст3 is a widely used carbon structural steel grade under GOST 380, providing a practical combination of strength, weldability and fabrication performance for general industrial applications. GOST 10704 requirements identify Ст3 as an applicable steel grade, with product quality controlled through the relevant technical specifications. For LSAW production, Huayang uses controlled plate forming and double submerged arc welding to achieve stable longitudinal weld quality. Weld nondestructive testing, hydrostatic testing, dimensional inspection and other examinations can be supplied according to project requirements.

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.
