ASME SB171 C71500 Copper Nickel Tubesheet Cuni7030

We are a professional manufacturer of ASME SB171 C71500 Copper Nickel Tubesheet Cuni7030 tubesheet in China.

What is ASME SB171 C71500 ?

ASME SB171 C71500 (70/30 Copper-Nickel) Plate is a high-strength, corrosion-resistant copper alloy composed of 70% copper and 30% nickel, with small amounts of iron and manganese for enhanced durability. It is widely used in marine, offshore, heat exchangers, desalination plants, and power generation applications due to its superior resistance to seawater corrosion and biofouling.

C71500 Copper Nickel “70/30” (CDA 715) Copper nickel offers excellent corrosion resistance, especially in marine salt water environments. 

C71500 Tube sheet

Tubesheets are essential components in heat exchangers, boilers, and pressure vessels, providing a structural foundation for securing tube bundles that facilitate fluid heat transfer. We manufacture plates, discs, baffles, and finished tubesheets for shell and tube heat exchangers in various materials, all manufactured in line with major international standards, including ASTM, ASME, DIN, and EN.
