Nadia Tube Fittings is a well-respected manufacturer and supplier of Super Duplex Stainless Steel Thermowells based in Kuala Lumpur, Malaysia. They provide strong and corrosion-resistant solutions for temperature measurement in tough industrial settings. These thermowells are specifically designed to safeguard temperature sensors like thermocouples and RTDs from harsh process conditions, ensuring accurate readings and prolonging the life of the sensors. With outstanding resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion, Super Duplex Stainless Steel Thermowells are commonly utilized in offshore, marine, oil & gas, chemical, and power generation sectors. Built to meet international standards, they guarantee safety, durability, and reliable performance even in the extreme conditions found in Malaysia.
Typically made from grades UNS S32750 and S32760, Super Duplex Stainless Steel Thermowells boast a balanced microstructure of ferrite and austenite, which provides exceptional strength and corrosion resistance. Their composition includes around 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen, all of which enhance their ability to withstand aggressive environments. These thermowells exhibit very high tensile strength, remarkable yield strength, and excellent fatigue resistance compared to standard stainless steels. They maintain their toughness even at low temperatures and offer superior erosion and corrosion resistance in seawater and chemical applications. Precision manufacturing guarantees dimensional accuracy, a long service life, and leak-tight performance.
