Pipe Threading

Threaded pipes can provide an effective seal for pipes transporting liquids, gases, steam, and hydraulic fluid. We thread any length of pipe in diameters ranging from 1/8” to 20”. Tapers available are NPT*, NPS*, 3/16” Peerless, and 8 round taper. (See fabrication services page for larger diameters).

*National Pipe Thread is a U.S. standard for tapered (NPT) or straight (NPS) threads used to join pipes and fittings. ANSI/ASME standard B1.20.1 covers threads of 60-degree form with flat crests and roots in sizes from 1/16 inch to 24 inch Nominal Pipe Size. The taper rate for all NPT threads is 1/16 (3/4 inch per foot) measured by the change of diameter (of the pipe thread) over distance. The taper divided by a center line yields an angle 1° 47′ 24″ or 1.7899° as measured from the center axis.
