What Are Threaded Flanges?
Threaded Flange is a pipe flange that is threaded to the pipe and can be installed without welding, suitable for low pressure, small diameter or frequent disassembly scenarios.
Threaded/Screwed Flanges have threads and can be fitted to pipes that have external threads. Threaded/Screwed Flanges are low priced, fit best for small pipes and can be used in low-pressure applications. They are very beneficial in highly combustible industries where welding is dangerous.
Threaded Flange Structural Features:
- Internal thread design: The flange bore is machined with internal threads (generally tapered thread NPT or parallel thread BSP), which are matched with the pipe external threads for screwing.
- Sealing surface type: common convex (RF), flat (FF) or ring joint surface (RTJ), through the thread sealant or gasket to achieve sealing.
- Weldless connection: relies on threaded occlusion fixing, avoiding the effect of high temperature welding on material properties.
- Flange holes: bolt holes are evenly distributed for easy alignment and fastening with other flanges.

Threaded Flanges Core Advantages:
- Easy installation: no welding required, suitable for environments where fire is prohibited (e.g. flammable and explosive areas) or temporary piping systems.
- Removability: easy to maintain and reuse, suitable for interfaces that require frequent disassembly (e.g., instrumentation, valve connections).
- Economy: save welding cost and time, especially for small diameter low pressure pipeline.
- Material compatibility: suitable for materials with poor weldability (e.g. cast iron, certain alloys).
Applications of Aluminum Threaded Flanges:
- Low pressure utility systems: water treatment, fire hoses, compressed air piping.
- Gas distribution: low-pressure natural gas or liquefied petroleum gas (LPG) piping.
- Chemical industry: low-pressure transportation of non-corrosive media (need to cooperate with sealant).
- Instrumentation and equipment connection: pressure gauges, sensors, interfaces for small pumps and valves.
- Special environment: mines, oil and gas wellheads and other places that require explosion-proof.
