Nickel Alloy Inconel 725 Pipe
Product Detail
Inconel 725 (UNS N07725) seamless and heavy-wall tubing solutions are specifically designated for deep-well downhole tubulars, subsea flowlines, high-strength marine fasteners, and sour gas equipment. Because its high strength is achieved via precipitation age-hardening rather than heavy cold reduction, large cross-sectional pipes maintain uniform strength and outstanding resistance to hydrogen embrittlement.
