Our Inconel BSP/NPT fittings are typically crafted from Inconel 600, 625, or 825 alloys, which are primarily made up of nickel (58–72%), chromium (14–23%), and iron (5–10%), along with trace elements like molybdenum, niobium, and cobalt. These alloys are known for their remarkable strength, oxidation resistance, and ability to withstand acidic and high-temperature environments. They boast impressive mechanical properties, including a tensile strength of up to 100 ksi (690 MPa) and a yield strength around 45 ksi (310 MPa), along with excellent elongation and hardness, making them perfect for high-pressure and corrosive service applications.

Inconel BSP / NPT Fittings Uses
Inconel BSP/NPT fittings are widely utilized in industries that require exceptional corrosion and heat resistance. Their robust characteristics make them ideal for oil and gas pipelines, chemical processing, marine engineering, nuclear reactors, and aerospace systems. These fittings guarantee leak-proof connections in high-pressure and high-temperature settings, even when faced with aggressive acids or seawater. The durability of Inconel under stress and its ability to resist scaling at elevated temperatures also make it a top choice for heat exchangers, pressure vessels, and steam generators. At Paul Tube Fittings, we deliver these essential components to ensure reliability, safety, and efficiency across a wide range of industrial operations.
