Welding Codes for Pipe and Tube
AWS, ASME, and API are the main organizations who have codes specific to pipe welding in the US.
- AWS: American Welding Society (Most codes touch on either pipe or tube)
- ASME: American Society of Mechanical Engineers
- API: American Petroleum Institute (Specific to oil and gas industry standards)
