The 406.4 mm diameter provides substantial flow capacity for medium-to-large industrial fluid transportation systems.
Material Performance and Application
ASTM A53 Grade B is a widely used carbon steel grade with a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa, providing a practical combination of strength, ductility, and weldability for general pressure and mechanical service. It is commonly selected for water, air, steam, and other non-corrosive or mildly corrosive industrial services. Huayang DN400 ERW steel pipe is produced through controlled forming and high-frequency welding, with attention to weld integrity, roundness, straightness, and wall thickness consistency. Quality control can include hydrostatic testing, ultrasonic or other weld inspection, tensile testing, flattening testing, dimensional inspection, and chemical composition analysis according to the applicable specification. For industrial pipelines exposed to moisture or buried conditions, Huayang can provide FBE, 2PE, 3PE, and internal epoxy coating systems to improve corrosion protection and extend service life.

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.
