How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

For Use With: Air, Steam, Oil, Water, Natural Gas
Specifications Met: ASTM A733, ASME B1.20.1, ASTM A53
Fittings: Use Class 125 and 150 iron and steel

Assortments contain threaded pipe in various lengths. Pipe is Schedule 40 and can handle low-pressure applications. It is welded, so there is a weld bead on the inside. Use in noncorrosive environments.

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Standard-Wall Galvanized Steel Threaded Pipe Nipple and Pipe Assortments

For Use With: Air, Steam, Oil, Water, Natural Gas
Specifications Met: ASTM A733, 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.
