Product Overview
Huayang 12 Inch ERW steel pipe is manufactured for pipeline systems requiring stable mechanical properties, accurate dimensions, and consistent longitudinal weld quality.
| Parameter | Specification |
|---|---|
| Nominal Size | 12 Inch |
| Outside Diameter | 323.9 mm |
| Material Grade | API 5L Grade B PSL1 |
| Manufacturing Process | High Frequency ERW |
| Wall Thickness | Project specified |
| Main Application | Pipeline Transportation |
The 12-inch size offers a practical flow capacity for medium-diameter transmission and distribution pipelines.
API 5L X60 PSL2 Material Performance
API 5L Grade B PSL1 has a minimum yield strength of 245 MPa and a minimum tensile strength of 415 MPa, providing a balanced combination of strength, ductility, and weldability for conventional line pipe applications. Its relatively moderate strength level makes Grade B suitable for many oil, gas, water, and industrial fluid transportation systems where higher-strength grades are not required. Huayang manufactures 12-inch ERW pipe through controlled forming and high-frequency electric resistance welding, maintaining consistent outside diameter, straightness, wall thickness, and weld integrity. Quality control can include hydrostatic pressure testing, ultrasonic weld inspection, tensile testing, flattening testing, dimensional verification, and chemical composition analysis according to the applicable API 5L requirements. Depending on the service environment, FBE, 2PE, 3PE, and internal epoxy coating systems can be supplied to improve corrosion protection and support long-term pipeline operation.

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.
