C70600 CuNi 9010 BW LR Copper Nickel Elbow, EEMUA 146, 45/90 Degree Butt Welding Fittings
Our EEMUA 146 C70600 CuNi 9010 BW LR 45/90 degree butt welding
copper nickel elbows are high-performance pipeline components,
strictly manufactured in compliance with EEMUA 146 international standard (incorporated in PUB NO
234-2015 for offshore applications). Crafted from premium C70600
copper nickel alloy (CuNi 9010), these fittings adopt butt welding
(BW) connection and long radius (LR) design, specialized for
industrial pipeline systems requiring reliable connection,
corrosion resistance and stable fluid transmission.
The core material C70600 (CuNi 9010) is a high-quality
copper-nickel alloy with nominal composition of 88.0%-90.0% copper
and 9.0%-11.0% nickel, boasting excellent corrosion
resistance—especially against seawater, chemical media and
atmospheric oxidation. This makes the elbows ideal for harsh
working environments such as marine engineering, offshore platforms
and chemical processing plants, where corrosion resistance is
critical for long-term operation.
We offer two angle options (45° and 90°) to meet different pipeline
direction change needs: 45° elbows for moderate turns, and 90°
elbows for right-angle connections. The long radius (LR) design
(curvature radius = 1.5 times the pipe diameter) ensures smooth
fluid flow, reduces flow resistance and pressure loss, making it
suitable for high-pressure pipeline systems. Adopting butt welding
(BW) connection, these elbows provide a firm, leak-proof joint with
high structural strength, compatible with TIG/MIG welding
processes, and the weld strength is consistent with the base
material.
Each elbow undergoes precision forging and machining, ensuring
accurate dimensions, smooth inner walls and tight tolerances, fully
complying with EEMUA 146 standard requirements for copper nickel
butt welding fittings. All fittings undergo strict quality
inspection, including material composition detection (XRF), weld
flaw detection (UT/PT), pressure resistance verification and
corrosion resistance test, and can provide EN10204 3.1
certification. Widely applied in marine, chemical, and power plant
pipeline systems, these fittings provide a safe, durable and
cost-effective solution for global industrial customers. |
