Product Overview
Huayang GOST 10704 Ст1 LSAW steel pipe is designed for water supply systems, combining stable welded construction with practical strength and dimensional accuracy.
| Parameter | Specification |
|---|---|
| Material Grade | Ст1 |
| Standard | GOST 10704 |
| Manufacturing Process | LSAW |
| Welding Method | Double Submerged Arc Welding |
| Pipe Type | Longitudinally Welded Steel Pipe |
| Main Application | Water Supply Systems |
The LSAW process is suitable for large-diameter water transmission pipes, providing controlled forming, stable longitudinal welds and consistent dimensional accuracy.
Ст1 Material Performance
Ст1 is a low-carbon structural steel grade specified under the GOST 380 system and commonly associated with general-purpose steel products. Its relatively low carbon content supports good weldability and fabrication performance, making it suitable for conventional engineering and water-supply applications when permitted by the project specification. Huayang manufactures large-diameter LSAW steel pipe through controlled plate forming and double-sided submerged arc welding, with dimensional inspection, weld nondestructive testing and hydrostatic testing available according to applicable requirements. For water supply projects, external anti-corrosion systems such as 3PE or FBE can be applied according to service conditions and customer specifications.

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.
