ASTM A210 Boiler Tubes Seamless Pipes
Features
- Seamless construction with no weld seam to limit pressure or temperature performance
- Medium carbon steel for higher strength and better creep resistance than A179 and A192
- Two grades to choose from, with Grade C offering the higher strength
- Cold finished tubes heat treated after drawing for uniform properties
- Every tube pressure tested and mechanically checked before dispatch
- Custom lengths, end finishes, and surface treatments available
