Piping, Valves, and Fittings: UA Apprenticeship Review

Flashcards covering pipes, joints, fittings, couplings, and materials from the UA Apprenticeship coursework.

Nominal pipe size

The measurement standard used to identify sizes of pipe.

Line couplings

Couplings that are manufactured to be slightly longer than merchant couplings.

Merchant couplings

Standard couplings that line couplings are slightly longer than.

PVC and CPVC plastic pipe

Types of plastic pipe that are usually joined using a special solvent.

Brazing filler metal

A designation for a brazing alloy evaluated by whether it possesses a melting temperature of at least $640^\circ\text{F}$.

Carbon steel

The term applied to steels that contain carbon alone.

Mechanical joint

A piping connection that requires the use of a special coupling or gasket and flange assembly.

Compression joints

Piping joints generally used with captive sleeves on fittings.

Uniform lengths of steel pipe

Standard fabricated lengths of steel pipe that are specified with a tolerance of $\pm 1\,\text{inch}$.

Flanges

Piping components manufactured in sizes that extend down to small fractional dimensions such as $1\,\text{inch}$ or smaller.
