A collar flange (threaded type) is a type of flange designed to connect to pipes through internal threading instead of welding. The pipe is screwed directly into the flange bore, making this flange ideal for systems where welding is not possible or practical, such as flammable or high-temperature environments.
Also known as a threaded collar flange, it typically consists of a flat-faced flange with a tapered internal thread and is used with threaded pipes in low-pressure and non-critical applications.
Key Features:
- Threaded Connection: Eliminates the need for welding; easy to install.
- Standard Tapered Threads: Usually NPT (National Pipe Thread) or BSPT for secure and leak-tight joints.
- Available in Various Materials: Carbon steel, stainless steel, brass, or plastic, depending on the application.
- Multiple Pressure Ratings: Typically available in ANSI/ASME pressure classes such as 150, 300, etc.
- Reusable and Replaceable: Can be easily removed or replaced without cutting the pipe.
- Compact and Durable Design: Ideal for small spaces and rugged applications.
Available - 63/75/90MM
