Material Performance and Application
Huayang 165 mm ERW steel pipes are manufactured from high-quality carbon steel coils using advanced high-frequency electric resistance welding technology, ensuring uniform weld strength, accurate dimensions, and smooth internal surfaces for efficient water flow. Common materials such as API 5L Grade B and ASTM A53 Grade B provide reliable mechanical properties, with a minimum yield strength of 240–245 MPa and a minimum tensile strength of 415 MPa. The 165 mm diameter is widely used in municipal water distribution networks, residential water supply systems, industrial utility pipelines, and urban infrastructure projects. Huayang applies strict quality control including hydrostatic pressure testing, ultrasonic weld inspection, eddy current testing, dimensional inspection, and mechanical property verification. FBE, 2PE, and 3PE coating solutions are also available to improve corrosion resistance and extend pipeline service life in different soil and water conditions.

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.
