Frequently Asked Questions – Monel Buttweld Fittings

Monel buttweld fittings provide exceptional resistance to corrosion from seawater, acids, and high-temperature conditions, rendering them suitable for offshore and chemical applications where stainless steel typically fails.

Indeed. Monel 400 delivers substantial mechanical strength, whereas Monel K500 presents even greater tensile and yield strength due to age-hardening, making it ideal for high-pressure and high-stress scenarios.

The relevant standard specifications include:
  • ASTM B366
  • ASME B16.9
  • ANSI B16.28
  • MSS-SP-43

Certainly. We provide fittings that are certified for sour service conditions (H2S environments) according to NACE MR0175 standards.

Monel K500 is a more robust variant of Monel 400, attributed to precipitation (age) hardening, and it exhibits enhanced wear resistance and higher hardness levels.

Yes. All fittings are dispatched with Material Test Certificates (MTCs) and can be subjected to inspection by globally recognized agencies like BV, SGS, TUV, and DNV upon request.
