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.

Standard-Wall Galvanized Steel Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Welded pipe has 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.

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.

Standard-Wall Galvanized Steel Pipe Nipples and Pipe for Joining Dissimilar Metals

For Use With: Water
Max. Temperature: 225° F
Specifications Met: See table
Fittings: Use 125 or 150 copper, galvanized iron, and galvanized steel

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.
