Paul Tube Fittings is a Houston, USA-based leading manufacturer and supplier of Super Duplex Stainless Steel Thermowells. With an excellent reputation for quality and reliability, the company supplies diverse industries with precision-made thermowells ideal for harsh environments. Their thermowells provide utmost resistance to corrosion, pressure, and temperature, which are ideal for high-demand applications. Paul Tube Fittings utilizes sophisticated manufacturing techniques and rigorous quality controls to make sure all products conform to international standards. Committed to innovation and customer satisfaction, the company offers bespoke solutions to suit special industrial applications in oil & gas, petrochemical, and marine industries.
Super Duplex Stainless Steel Thermowells usually have 24–26% Chromium, 6–8% Nickel, 3–5% Molybdenum, and minute traces of Nitrogen and Copper. This even composition improves corrosion resistance, particularly against pitting and stress corrosion cracking. Mechanically, these thermowells have a high yield strength (≥550 MPa), tensile strength (≥750 MPa), and good toughness in low temperatures. Their double-phase microstructure (austenite and ferrite) gives an optimum combination of strength and ductility and is best suited for high-stress and corrosive conditions prevalent in most industrial environments.

Super Duplex Stainless Steel Thermowells find extensive applications in high corrosion resistance and mechanical strength-demanding industries. Typical uses are in offshore oil platforms temperature sensing, chemical plants, marine, and desalination plants. Thermowells guard temperature sensors against process conditions that are harsh, including high pressure, corrosive chemicals, and severe temperature extremes. They are best suited for power generation, petrochemical refining, and pharmaceutical production. Their strength and erosion resistance also qualify them for use in flow measuring systems, providing precise and secure data gathering while prolonging the life of sensors operating in harsh application conditions.
