Material Performance and Application
Huayang DN200 API 5L PSL1 Grade B ERW steel pipes are manufactured from premium hot-rolled pipeline steel coils using advanced high-frequency electric resistance welding technology, ensuring excellent weld integrity, dimensional consistency, and pressure-bearing capability. API 5L PSL1 Grade B has a minimum yield strength of 245 MPa and a minimum tensile strength of 415 MPa, providing excellent weldability, ductility, and resistance to installation stresses. The DN200 size is widely used for crude oil transmission, natural gas gathering systems, refinery process lines, and industrial energy infrastructure. Every pipe undergoes hydrostatic pressure testing, ultrasonic weld inspection, eddy current testing, tensile testing, flattening tests, and full chemical composition verification to ensure compliance with API 5L requirements. Huayang also provides FBE, 2PE, 3PE, and internal epoxy lining to improve corrosion resistance and extend pipeline service life in buried and above-ground 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.
