Material Performance and Application
Huayang 140 mm ERW steel pipes are manufactured from high-quality carbon steel coils through advanced high-frequency electric resistance welding technology, ensuring uniform weld quality, smooth internal surfaces, and precise dimensional control. Common materials such as API 5L Grade B and ASTM A53 Grade B provide reliable mechanical properties, with Grade B featuring a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa. The 140 mm diameter is widely applied in municipal water supply networks, irrigation systems, industrial circulating water pipelines, and utility engineering projects. Huayang performs hydrostatic testing, ultrasonic weld inspection, eddy current testing, chemical composition analysis, and mechanical property verification to guarantee compliance with international standards. External coatings such as FBE, 2PE, and 3PE can be provided to improve corrosion resistance and extend service performance in different water environments.

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.
