DEENPU Integral Treating Irons
Union Ends
Home › Hammer Unions, Treating Irons & Flowline Equipment › Integral Treating Irons
Product Overview
DEENPU integral treating irons are one-piece high pressure pipe sections with the wing union end connection machined integrally into the body — eliminating welds and threads from the pressure boundary. The result is a uniform bore, better flow characteristics and uniform heat treatment through the whole joint.
Available in carbon and alloy steel, in lengths up to 12 feet, for cold working pressures to 15000 PSI, with sour service (NACE) options. The wing nut detaches via a circlip for fast field disassembly and seal replacement.

Frequently Asked Questions
Q: Why integral ends instead of welded unions?
A: Welds and threads are stress concentrators in the pressure boundary. Integral ends remove them completely, giving higher fatigue life and uniform heat treatment — critical for 10000+ PSI service.
Q: Can treating irons be used on sour wells?
A: Yes, NACE MR0175 compliant material and hardness control are available.
