ASTM steel pipe refers to carbon steel pipe used in oil and gas transmission systems. It is also used to transport other fluids such as steam, water, and mud.
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 | - |
