Precision Seamless CuNi 70/30 Pipe ASME SB111 C70600 High Pressure Tube

2.Product  Advantages

• Superior resistance to hydrogen embrittlement – Can be used in wet H₂S environments up to 50 ppm without cracking.

• Excellent low-temperature toughness – Impact strength remains high down to -250°C (no ductile-to-brittle transition).

• Resistance to chlorine dioxide – Suitable for paper mill bleach plants (unlike stainless steel).

• Non-sparking property – Safe for use in explosive atmospheres (ATEX Zone 1 and 2).

• Low maintenance requirement – Oxide layer eliminates need for internal coating or cathodic protection.

3.Product Applications

• Liquefied gas transfer – LNG and LPG loading arms (cryogenic service down to -196°C after impact testing).

• Firewater systems on FPSO vessels – Deck ring main and hydrant risers.

• Heat recovery steam generators – Low-pressure evaporator tube bundles.

• Marine condensers – Seawater side tubing in naval vessels (low magnetic signature).

• Offshore wind farms – Internal cooling circuits for turbine converters.

• Dockside potable water lines – NSF/ANSI 61 certified (for 90/10 alloy only).
