Hastelloy C276 Tube to Tube Fittings

Hastelloy C-276 is a nickel-molybdenum-chromium superalloy known for its exceptional corrosion resistance and high-temperature stability. It is particularly well-suited for harsh environments, including chemical processing, marine applications, and high-temperature industrial processes.Tube-to-Tube Fittings Made from Hastelloy C-276**1. Types of Tube-to-Tube Fittings:Compression Fittings:Types: Straight, elbow, tee, cross.Features: These fittings have a compression nut and ferrule (compression ring) that compresses around the tube to create a tight seal. They are commonly used in applications where a leak-tight connection is necessary and are suitable for handling high pressures.Flare Fittings:Types: Male and female flare, flare-to-tube.Features: Utilize a conical seat to provide a metal-to-metal seal. These fittings are ideal for high-pressure applications and are also effective in environments prone to vibrations.Union Fittings:Types: Straight unions, elbow unions, tee unions.Features: Allow for easy disassembly of tubing without removing the entire fitting assembly. Useful in maintenance and repair situations.Adapter Fittings:Types: Male to female adapters, reducing adapters, transition adapters.Features: Facilitate connections between different sizes or types of tubing or adapt to different standards.Push-to-Connect Fittings:Types: Straight, elbow, tee.Features: Designed for quick, tool-free connections. Utilize a collet and O-ring mechanism to secure the tube.**2. Specifications:Material Properties:Corrosion Resistance: Excellent resistance to oxidizing and reducing acids, including sulfuric, hydrochloric, and phosphoric acids.Temperature Range: Effective in temperatures up to approximately 1,800°F (982°C).Mechanical Properties: High strength and good ductility. Retains properties at high temperatures.Dimensions:OD (Outer Diameter): Customarily specified in inches or millimeters.Wall Thickness: Depends on the pressure rating and fitting type.Pressure Ratings:Varies by Fitting Type: The maximum allowable working pressure is dependent on the fitting type, size, and application conditions. Always consult specific manufacturer data for detailed pressure ratings.Standards:Common Standards: ASTM B574, ASTM B622, and ASTM B626 are relevant for Hastelloy C-276 products. Check for industry-specific standards as required.**3. Applications:Chemical Processing: Handling of aggressive chemicals and acids in reactors, pumps, and pipelines.Marine Environments: Parts in shipbuilding and offshore oil and gas applications.Aerospace: High-temperature and high-stress components.Industrial: High-performance systems needing exceptional corrosion and temperature resistance.**4. Considerations:Compatibility: Ensure that Hastelloy C-276 fittings are compatible with the tubing material and the specific application conditions.Installation: Proper installation is crucial for ensuring leak-proof connections and maintaining the integrity of the system.When choosing Hastelloy C-276 tube-to-tube fittings, refer to manufacturer specifications for exact dimensions, pressure ratings, and temperature tolerances. This ensures that the fittings meet the necessary requirements for your application.
