A short pipe fitting featuring an external thread at one end and a plain or beveled end at the other; it is used to transition between a threaded equipment connection and a welded joint or pipeline end. Its length and the configuration of the unthreaded end are typically customized according to installation dimensions.
Manufactured with advanced CNC equipment and proven processes, our flanges, pipe bends, and fittings deliver accurate dimensions, stable sealing performance, and dependable installation across demanding industrial applications.
Reference Standards: Materials and dimensions for pipe nipples comply with ASTM A733-25 or relevant pipe standards; NPT threads comply with ASME B1.20.1.
Dimensions: ASTM A733 covers standard steel pipe sizes (NPS 1/8–12) and standard or custom lengths; specific configurations (e.g., single-end threading) are subject to project drawing confirmation.
Ends: One end threaded (male); the other end plain, beveled, or machined according to drawings.
Materials: Carbon steel pipe, stainless steel pipe, or project-specified alloy pipe.
Ordering Details: Nominal pipe size (NPS), wall thickness/Schedule (Sch), total length, thread length and standard, configuration of the other end, and surface finish.
Ordering/Acceptance: Confirm nominal pipe size, wall thickness/Schedule, total length, thread standard and effective length, configuration of the other end, pipe material standard, and surface finish; verify via thread gauges and dimensional inspection.
