Monel 400 Pipe Fittings Manufacturer, Supplier, Stockist, and Exporter in India – Mcneil Instruments
Mcneil Instruments is a trusted manufacturer, supplier, and exporter of Monel 400 pipe fittings in India. This solid-solution alloy consists of approximately 67% nickel and 23% copper, offering exceptional resistance to seawater and sour gas environments. It is extremely effective against neutral and alkaline solutions, reducing microbial corrosion, and maintaining good mechanical strength.
Why Monel 400 Stands Out:
- Superior resistance to fresh/salt water, hydrofluoric acid, and sulfuric acid
- Excellent mechanical strength and durability up to 315 °C (600 °F)
- Ideal for flange and weld fittings in marine and heat exchanger units
- Excellent weldability and ease of fabrication
