Product Overview
Huayang 168 mm ERW steel pipe combines accurate dimensions, consistent weld quality, and reliable carbon steel performance for structural engineering applications.
| Parameter | Specification |
|---|---|
| Outside Diameter | 168 mm |
| Material Grade | API 5L Grade B PSL1 |
| Manufacturing Process | High Frequency ERW |
| Wall Thickness | 4.0–12.0 mm |
| Main Application | Structural Steel Pipe |
The 168 mm diameter offers a practical balance between structural capacity, material efficiency, and fabrication convenience.
Material Performance and Application
API 5L Grade B PSL1 has a minimum yield strength of 245 MPa and a minimum tensile strength of 415 MPa, providing good strength, ductility, and weldability. Although API 5L is primarily a line pipe specification rather than a structural hollow section standard, its Grade B steel can be considered for structural applications only when the project specification and design engineer permit its use. Huayang manufactures 168 mm ERW steel pipe through controlled forming and high-frequency welding, maintaining stable outside diameter, wall thickness, straightness, and weld integrity. Typical quality controls include dimensional inspection, weld inspection, tensile testing, flattening testing, hydrostatic testing where required, and chemical composition verification. For structural projects, the applicable structural steel standard should be confirmed before procurement to ensure the material designation and mechanical requirements match the engineering design.

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.
