Nickel Alloy Pipes are high-performance pipes made from nickel-based alloys that offer exceptional corrosion resistance, heat resistance, and strength in extreme environments. These pipes are ideal for chemical processing, petrochemicals, marine applications, oil & gas, heat exchangers, power plants, and high-temperature services.

Nickel alloys maintain stability and mechanical properties even at very high temperatures, making them perfect for critical applications.

Monel Pipe Overview

1. Description:
Monel pipes are nickel-copper alloy pipes known for their exceptional resistance to corrosion, especially in marine and chemical environments. They exhibit high strength and toughness across a wide temperature range, making them suitable for demanding industrial applications.

2. Common Monel Grades:

• Monel 400 (UNS N04400): Excellent resistance to seawater and hydrofluoric acid; good mechanical properties.

• Monel K500 (UNS N05500): Age-hardened version of Monel 400 with higher strength and hardness.

3. Manufacturing Types:

• Seamless Pipes

• Welded Pipes

• ERW Pipes

• Fabricated Pipes

4. Standards & Specifications:

• ASTM B165 / B725

• ASME SB165 / SB725

• ASTM B564 (for flanges & fittings)

• ASTM B366 (for butt-weld fittings)

5. Size Range:

• Outer Diameter: 1/8" NB to 12" NB and above

• Wall Thickness: Sch 5S to Sch XXS / Custom

6. Mechanical & Chemical Properties (Typical for Monel 400):

• Tensile Strength: ~550 MPa min

• Yield Strength: ~240 MPa min

• Elongation: 35% min

• Ni: 63% min
