Product Overview
Huayang ASTM A672 Grade C60 Class 22 LSAW steel pipe is designed for high-pressure service using pressure-vessel-quality carbon steel plate.
| Parameter | Specification |
|---|---|
| Material Grade | ASTM A672 Grade C60 |
| Class | Class 22 |
| Manufacturing Process | LSAW |
| Welding Method | Electric Fusion Welding |
| Heat Treatment | Stress Relieved |
| Main Application | High-Pressure Piping |
The Class 22 designation requires stress relief together with radiographic examination and pressure testing, providing controlled weld integrity for demanding pressure applications.
ASTM A672 C60 Class 22 Material Performance
ASTM A672 Grade C60 is produced from pressure-vessel-quality carbon steel plate corresponding to ASTM A516 Grade 60. The material provides a minimum yield strength of 220 MPa and tensile strength of 415–550 MPa. Class 22 specifies stress-relieved pipe with radiographic examination and pressure testing. LSAW manufacturing is suitable for large-diameter applications because steel plate can be accurately formed and longitudinally welded using electric fusion welding. Huayang can provide dimensional inspection, weld nondestructive testing and hydrostatic testing according to applicable ASTM requirements and project 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.
