Thin-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe
- For Use With: Air, Natural Gas, Oil, Water
- Specifications Met: ASTM A312, ASME B36.19
- Fittings: Use unthreaded Schedule 10 stainless steel
Also known as Schedule 10, this pipe is thin and lightweight. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe has a welded construction, so there is a weld bead on the inside.
304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.

Thin-Wall Aluminum Unthreaded Pipe Nipples and Pipe
- For Use With: Air, Oil, Water
- Fittings: Use Schedule 10 aluminum
Also known as Schedule 10, this pipe has the thinnest walls of all our aluminum pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, which provides a smooth interior for unrestricted flow. It is lightweight with good corrosion resistance.
