  • Carbon Steel Pipe Threading

Pipe Threading

Pipe ThreadingThreaded 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” thru 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 Pipe Threads60-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.
