ASTM steel pipe is a kind of carbon steel pipe which is utilized in oil & gas transmission applications. It is equal way good for the other liquids like steam, water and mud transportation.
The ASTM STEEL PIPE specification covers both welded and seamless fabrication types.
Welded Types: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe
Common types of ASTM welded pipe are as follows:
| Welded Types | Applicable pipe diameters | Remark | |
| ERW | Electric resistance welding | Less than 24 inches | - |
| DSAW/SAW | Double-sided submerged arc welding/submerged arc welding | Large diameter pipes | Alternative welding methods for ERW |
| LSAW | Longitudinal submerged arc welding | Up to 48 inches | Also known as JCOE manufacturing process |
| SSAW/HSAW | Spiral submerged arc welding/spiral submerged arc welding | Up to 100 inches | - |
