Carbon Steel ASTM A672 EFW Pipes
ASTM A672 pipes are basically carbon steel pipes that are manufactured using an electric fusion welding process. In many industrial projects they are preferred where the operating temperature is not extremely high but the piping system still needs to handle considerable pressure. The pipes are produced from pressure-vessel quality steel plates and follow the ASTM A672 / ASME SA672 specification requirements.
In practical use, these pipes are often seen in refinery units, petrochemical plants and power generation facilities where reliable piping materials are required. The exact surface condition of the pipe may vary depending on the project. Some buyers prefer pipes in bare or black painted finish, while others specify galvanizing or protective coatings to reduce corrosion.
For applications where the operating environment is more aggressive, coatings such as PE, PP, EP or FBE can also be applied. These protective layers help prevent surface deterioration and allow the piping system to perform reliably for a longer period of time.
