Material Performance and Application
API 5L Grade B and ASTM A53 Grade B are widely used carbon steel grades, but they serve different specification purposes. API 5L Grade B is intended for line pipe and has a minimum yield strength of 245 MPa and minimum tensile strength of 415 MPa, while ASTM A53 Grade B has a minimum yield strength of 240 MPa and minimum tensile strength of 415 MPa. Huayang DN200 ERW steel pipe can be manufactured to the applicable standard required by the project, using controlled forming and high-frequency welding to maintain consistent weld quality and dimensional accuracy. Quality control may include hydrostatic testing, weld inspection, tensile testing, flattening testing, dimensional verification, and chemical composition analysis. FBE, 2PE, 3PE, and internal epoxy coatings are also available for applications requiring enhanced corrosion protection.

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.
