Standard-Wall Galvanized Steel Threaded
Pipe Nipple and Pipe Assortments
- For Use With: Air, Steam, Oil, Water, Natural Gas
- Specifications Met: ASTM A733, ANSI/ASME B1.20.1, ASTM A53
- Fittings: Use Class 125 or 150 galvanized iron and galvanized steel
- Flanges: Use Class 150 steel
Assortments contain threaded pipe in various lengths. The galvanized finish on this pipe provides fair corrosion resistance. Also known as Schedule 40, it is designed for low-pressure applications. Pipe is welded, so there is a weld bead on the inside.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

A plastic sleeve prevents destructive corrosion when connecting different metals. Pipe is also known as Schedule 40 and is designed for low-pressure applications. It is galvanized steel, which has fair corrosion resistance. Pipe is welded, so there is a weld bead on the inside. Not for use in heating systems that use hot liquids or gas.
