Cupro Nickel Pipe grades perform where carbon and stainless steel corrode. UNS C70600 contains 9-11% nickel for stable protective film formation. This stable film resists chloride pitting, biofouling and erosion at seawater velocity. As a trusted Cupro Nickel Pipe Manufacturer In India, Ganpat Industrial supplies. Ganpat Industrial forges, stocks and tests both grades to ASTM standards. Both grades are tested to ASTM B466 and ASTM B467 requirements. We ship across India, the UAE and the Middle East.

Welding Tips For Cupro Nickel ERW Pipe
Match Filler To Base Grade
Use CuNi filler matching 90/10 or 70/30 parent metal
Step 1
Prefer TIG / GTAW
TIG welding gives the cleanest, lowest-porosity joint
Step 2
Avoid Oxyacetylene Welding
Not recommended on Cu-Ni per ASTM B467 guidance
Step 3
Control Interpass Heat
Keep interpass temperature low to protect corrosion resistance
Step 4
Shield Root With Inert Gas
Argon back-purge prevents root oxidation on pipe joints
Step 5
Radiograph The Seam
RT or eddy-current check before the joint enters service
Step 6
Buy Copper Nickel Welded Pipe As Per ASTM B466 Standard for Marine & Industrial Use
