The ASME/ANSI B16.5 Threaded (TH) flange is a specialized flange designed for use in low-pressure, non-welded piping systems. Featuring internal threads, this flange is screwed directly onto the pipe, eliminating the need for welding. It is commonly used in industries where welding is not feasible, such as in explosive environments or temporary connections.
Material Specifications:
Threaded flanges are manufactured in various materials to suit specific operational requirements:
- Carbon Steel: ASTM A105, A350 LF2
- Stainless Steel: ASTM A182 F304, F316, F321
- Alloy Steel: ASTM A182 F11, F22
- Nickel Alloys: Inconel, Monel, Hastelloy
- Duplex Stainless Steel: ASTM A182 F51, F53
Material selection is based on the application’s requirements for temperature, pressure, and corrosion resistance.
Key Features:
- No Welding Required: Ideal for applications where welding is impractical or hazardous.
- Internal Thread Design: Screws directly onto the pipe for a secure connection.
- Cost-Efficient: Reduces installation time and labor costs.
- Pressure Range: Typically used for lower-pressure applications (Class 150, 300).
- Compliance with Standards: Manufactured to ASME/ANSI B16.5 specifications for accuracy and interchangeability.
Applications:
- Oil & Gas: Non-welded pipeline connections in explosive environments.
- Chemical Processing: Systems handling non-corrosive or mildly corrosive fluids.
- Plumbing: Low-pressure water and gas distribution systems.
- Fire Protection: Temporary or modular sprinkler systems.
- Maintenance and Repairs: Temporary or removable pipe connections.
