Applications & Selection Guide
Carbon steel half nipples (single-end threaded bosses) to ISO 7-1 / EN 10241 — one male-threaded end for the instrument or accessory, one plain end welded to the pipe or vessel.
Half nipples provide threaded take-off points for pressure gauges, thermowells, vents, drains, and sampling valves on welded carbon steel systems. Select the thread size to match the instrument connection; keep the welded end wall compatible with the parent pipe. Sizes are listed in the table above.
Quoted and sold per piece. Send the size, quantity, and destination in a quote request — typically ordered in batches alongside fittings and flanges for skid and vessel fabrication.
Sizes run from 21.3 mm (½") to 114.3 mm (4") outside diameter. The outside diameter is that of pipe with the same thread size, for example 33.7 mm for 1" and 60.3 mm for 2", so the plain end matches the take-off pipe and the threaded end the instrument or valve.
