What is a Threaded Flange?
A threaded flange, characterized by internal (female) threads designed to screw onto pipes or fittings with external (male) threads, that utilizes a screw thread to connect to a pipe.
A male thread is cut onto the pipe end, while a female thread is cut into the bore of the flange, allowing the pipe to be screwed directly into the flange without the need for welding. Key components of a flange include the flange hub (or threaded bore), bolt holes around the perimeter, and the flange face where a gasket is placed for sealing.
Thread Types
The available thread types include NPT (American standard, tapered), BSPP (British Standard Pipe Parallel), and BSPT (British Standard Pipe Tapered).
NPT and BSPT threads are tapered, designed to tighten progressively and create a seal through metal-to-metal contact with the aid of a thread sealant. BSPP threads are parallel and typically rely on a thread sealant, washer or gasket for sealing.
NPT (National Pipe Thread)
American standard, tapered design
60-degree thread angle with flat peaks
Creates seal through thread interference and sealant
BSPP (British Standard Pipe Parallel)
British parallel threads
55-degree thread angle with rounded form
Requires thread sealant, washer or gasket
BSPT (British Standard Pipe Tapered)
British tapered threads
55-degree thread angle with rounded form
Seals like NPT through thread taper with sealant
Threaded Flange Materials
Material options for these flanges include Mild Steel, Stainless Steel (grades 304, 316, and 2205), and Forged Steel (ASTM A105). The diversity in materials allows for suitability across various environments, from general utility services (Mild Steel, A105) to highly corrosive or high-strength applications (316, 2205 Duplex). Nearly all metal and plastic materials can be threaded.
