Product Description
CuNi 70/30 Copper Nickel Elbow, Erosion Resistant 90° LR ASME B16.9 Butt Weld Pipe Fitting
1.Product Description
This product is a seamless copper‑nickel elbow fitting manufactured from virgin alloy ingots with full traceability from melting to final inspection. The fitting is produced by hot‑induction bending or cold‑pushing processes, followed by solution annealing and pickling to remove surface oxides. Each piece is clearly marked with grade, size, schedule, heat number, and manufacturer‘s logo in accordance with ASTM E527 and MSS‑SP‑25. The product is designed for butt‑weld, socket‑weld, or threaded connections and is fully interchangeable with standard ASME/ANSI piping components.
2.Product Applications
This elbow is procured for installation in mission‑critical piping systems where material integrity and corrosion resistance are non‑negotiable. Typical application scenarios include:
-
Naval surface ships and submarines (seawater, auxiliary, and emergency systems)
-
Floating production, storage, and offloading (FPSO) units and fixed offshore platforms
-
Nuclear power plant secondary cooling circuits and emergency core cooling system (ECCS) piping
-
Municipal seawater reverse osmosis (SWRO) desalination pretreatment and high‑pressure feed lines
-
Shipyard newbuild and repair projects with class society approval requirements (DNV, ABS, LR, BV, CCS)
3 · Product Advantages
-
Full traceability – Each melt is independently certified with chemical and mechanical test reports (3.1 / 3.2 per EN 10204).
-
Proven supplier qualification – Meets NORSOK M‑650 and Shell DEP material procurement standards.
-
Consistent hardnés and grain size – Controlled solution annealing ensures grain size 0.035‑0.060 mm per ASTM E112.
-
Cost‑effective lifecycle – Higher initial cost offset by 3‑5× longer service life versus carbon steel / 316L in seawater.
-
Reduced inspection frequency – No periodic wall‑thickness monitoring required due to uniform corrosion behavior.
-
Globally stocked grades – C70600 and C71500 available ex‑stock in common dimensions for rapid deployment.
