Monel K500 Pipes | Monel K500 Seamless Pipes | Monel K500 Welded Pipes
High-Strength ASTM B163 Monel K500 Seamless & Monel K500 Welded Pipe Manufacturer & Supplier
Solitaire Overseas is a leading manufacturer and supplier of Monel K500 Pipes, a high-performance nickel-copper alloy that offers the same exceptional corrosion resistance as Monel 400 but with significantly higher strength and hardness. Our inventory includes best-selling Monel K500 Seamless Pipes, Monel K500 Welded Pipes, and ERW variants engineered to meet the demanding requirements of offshore, marine, oil & gas, and chemical processing industries.
We supply ASTM B165 and ASME SB165 compliant UNS N05500 Monel K500 Pipes, along with ASTM B163 Monel K500 Tubes, manufactured in accordance with ASTM, ASME, API, and NACE standards for sour service applications, with a size range extending from 15NB to 150NB, wall thicknesses from 0.6 mm to 20 mm, and outer diameters from 6.35 mm to 254 mm.
To meet diverse project specifications, our Monel K500 Pipe is available in single random, double random, and custom cut lengths with end configurations including plain, beveled, and threaded ends across seamless, ERW, welded, and fabricated types. As a precipitation-hardenable alloy, Monel K500 (UNS N05500) is uniquely non-magnetic and spark-resistant, making it ideal for submarine components, marine shafts, pump shafts, valve trim, cable wraps, and sensitive instrumentation.
While its corrosion resistance is comparable to Monel 400, the addition of aluminum and titanium enables age hardening, resulting in significantly higher mechanical strength; consequently, Monel K500 Seamless Pipes are widely used in high-stress applications such as heat exchangers, downhole tubing, and hydraulic systems.
In the oil & gas and marine engineering sectors, ASME SB165 UNS N05500 Monel K500 Pipe is preferred for elevated temperature and high-pressure service without compromising structural integrity, and our products are rigorously tested for chemical composition, grain structure, tensile strength, yield strength, hardness, hydrostatic pressure, and non-destructive examination to ensure compliance with NACE MR0175 standards.
The alloy composition typically includes 63% Nickel and 27–33% Copper, allowing Monel K500 pipes to achieve a minimum yield strength of 790 MPa and a tensile strength of 1100 MPa. With a melting point of approximately 1350°C, these pipes perform reliably under extreme thermal and corrosive environments, and we provide complete mill test certificates (MTC), third-party inspection reports, and export documentation upon request. Contact us today for the latest price list and technical support for Monel Pipes in India and global markets.

Types of Monel K500 Pipes
Monel K500 Seamless Pipes (ASTM B165 / ASME SB165)
Manufactured without a welded seam, offering superior dimensional accuracy, lower absolute roughness, and higher pressure ratings. Preferred for heat exchangers, high-pressure fluid systems, and subsea equipment.
Monel K500 Welded Pipes (ASME SB165 / ASTM B165)
Manufactured by longitudinally welded nickel-copper alloy strips, then annealed to relieve residual stresses. Cost-effective for moderate-pressure marine and chemical applications. All welds tested per radiographic and hydrostatic standards.
Monel K500 ERW Pipes
Produced using electric resistance welding, suitable for moderate pressure service. Uniform wall thickness, available in a wide range of schedules from SCH 10 to XXH.
Monel K500 Fabricated Pipes
Custom-fabricated for large-diameter or non-standard dimensions, engineered to project-specific requirements.

Frequently Asked Questions
What is the Monel K500 made of?
Monel K500 is a nickel-copper alloy with added aluminum and titanium to enhance its mechanical strength and hardness through age-hardening (precipitation hardening).
Where are Monel K500 pipes and tubes used?
They are used in marine engineering, chemical processing, oil & gas (including sour service), aerospace & defense, power generation, and desalination plants.
How does the Monel K500 differ from Monel 400?
Monel K500 offers higher strength, wear resistance, and fatigue resistance due to age-hardening, while still retaining Monel 400's exceptional corrosion resistance. The addition of aluminum and titanium enables precipitation hardening.
Can Monel K500 be welded?
Yes, it supports standard welding methods such as TIG, MIG, and resistance welding with minimal risk of cracking or distortion. Post-weld heat treatment may be recommended for critical applications.
What makes Monel K500 corrosion-resistant?
Its high nickel (63% min) and copper (27–33%) composition forms a protective oxide layer, resisting attack from seawater, acids, alkalis, and harsh chemicals.
