1-24" Seamless Copper Nickel Elbow 45/90/180°, EEMUA C70600 CuNi 90/10 70/30
Our 45/90/180 Degree 1-24" seamless elbows are strictly
manufactured in compliance with EEMUA international standards,
crafted from premium C70600 copper nickel alloy (available in CuNi
90/10 and CuNi 70/30 ratios). As seamless pipeline fittings, they
are designed to meet the diverse connection needs of industrial
pipeline systems, covering multiple angles and sizes to adapt to
different pipeline direction changes and installation scenarios.
The core material C70600 copper nickel alloy is available in two
common ratios: CuNi 90/10 (88.0%-90.0% copper, 9.0%-11.0% nickel)
and CuNi 70/30 (68.0%-72.0% copper, 28.0%-32.0% nickel), both
boasting excellent corrosion resistance—especially against
seawater, chemical media and atmospheric oxidation. The seamless
manufacturing process eliminates potential defects such as weld
seams, ensuring uniform wall thickness, compact structure and high
pressure-bearing capacity, suitable for high-pressure and
high-temperature industrial environments.
We offer three angle options (45°, 90°, 180°) and a wide size range
(1"-24") to meet various pipeline layout requirements: 45° elbows
for moderate direction changes, 90° elbows for right-angle turns,
and 180° elbows for U-shaped pipeline connections. Each seamless
elbow undergoes precision machining, ensuring accurate dimensions,
smooth inner walls and tight tolerances, fully complying with EEMUA
standard requirements for copper nickel seamless fittings, and
perfectly matching 1"-24" standard pipelines.
All fittings undergo strict quality inspection, including material
composition detection (XRF), dimensional accuracy verification,
pressure resistance test and corrosion resistance test, and can
provide EN10204 3.1 certification to ensure reliable performance
and long service life. Widely applied in marine engineering,
offshore platforms, chemical processing, seawater cooling systems
and power plants, our EEMUA C70600 CuNi 90/10 70/30 seamless elbows
(45/90/180°, 1-24") provide a safe, durable and cost-effective
solution for global industrial customers, perfectly adapting to
harsh corrosion and high-pressure pipeline connection scenarios.
Material Grade:
Copper Nickel C70600 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B111 and ASME SB111. C70600 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 90/10 alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities.
