12CrMoV alloy steel pipe

Alloy pipes are defined by steel pipes according to the production materials (that is, materials), as the name implies, they are pipes made of alloys; while seamless pipes are defined by steel pipes according to the production process (seamless), the difference from seamless pipes is Seamed pipes, including longitudinal welded pipes and spiral pipes.
