Carbon Steel Half Nipple

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.
