≤3.5 m/s safe seawater velocity
Lower material cost

70/30 Copper Nickel

30% nominal nickel content
365–517 MPa typical tensile strength
Up to 4.5–6 m/s safe seawater velocity
Longer service life at high flow

Cu-Ni 70/30 Weld Pipe Fittings Installation Process

1. Verify Grade & Documentation

Match NPS, schedule and grade to spec; check the mill certificate.

2. Clean & Bevel The Weld End

Degrease the joint and prepare a standard 37.5° bevel.

3. Align Bore Centreline

Square the fitting to pipe and tack at four points.

4. Preheat-Free TIG Root Pass

Cu-Ni needs no preheat; run a clean GTAW root pass.

5. Fill With ERCuNi Filler Wire

Complete fill passes using matching AWS A5.7 ERCuNi wire.

6. Visual & Dye Penetrant Check

Inspect the bead, then hydrotest before line closure.

What Are The Benefits Of Using Copper Nickel 70/30 Pipe Bend ?

No Dealloying Or Dezincification

Nickel addition prevents selective leaching in seawater, unlike brass fittings

Superior Biofouling Resistance

Copper ions in the alloy inhibit marine organism growth on the cap surface

Stable Across Marine Service Range

Performs from ambient seawater to elevated process temperatures without pitting

Single-Grade Standardisation

One cap grade covers seawater, brackish and process lines, fewer SKUs to stock

Lower Total Ownership Cost

Fewer replacements and re-inspections over decades of marine service

Widely Code-Approved

Accepted under ASME B16.11, DNV, ABS and Lloyd’s Register marine specifications

Frequently Asked Questions

What is the price of a Copper Nickel 70/30 Pipe Fitting?

Price depends on NPS, schedule, type and testing level

Is a UNS C71500 fitting suitable for seawater lines?

Yes, UNS C71500 is the preferred grade for high-velocity seawater

What is the HSN code for copper nickel fittings?

Copper-nickel pipe fittings fall under HSN 7412 20

Can Cu-Ni 70/30 fittings be welded to Cu-Ni 90/10 pipe?
