The DN200 diameter provides a practical solution for medium-capacity transmission and distribution pipelines.
Material Performance and Application
API 5L Grade B PSL1 is a widely used carbon steel line pipe grade, offering a minimum yield strength of 245 MPa and a minimum tensile strength of 415 MPa. Its relatively low carbon content and balanced chemical composition provide good weldability and reliable ductility, making it suitable for conventional pipeline transportation service. Huayang manufactures DN200 ERW pipe through controlled forming and high-frequency welding, with attention to weld quality, roundness, straightness, and dimensional tolerance. The pipe can be supplied for oil, gas, water, and industrial fluid transmission, with hydrostatic testing, weld inspection, mechanical testing, and chemical analysis performed according to the applicable specification. External FBE, 2PE, or 3PE coatings can also be applied when enhanced corrosion protection is required.

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.
