When it comes to plumbing and industrial applications, understanding drainage pipes and fittings is crucial for ensuring efficient fluid transportation systems. From residential plumbing to industrial processing, pipe fittings serve as the vital connectors that help create complete piping systems. This comprehensive guide explores the various types of pipe fittings, their materials, and essential maintenance practices.
Common Types of Pipe Fittings
1. Elbow Fittings: Elbow fittings are designed to change the direction of flow between pipes. They commonly come in 45-degree and 90-degree angles, though other angles are available for specialised applications. These fittings are essential in both industrial settings and residential plumbing systems.
2. Coupling Fittings: Couplings are straight fittings used to connect two pipes of the same diameter. They come in various styles:
· Regular couplings
· Reducing couplings
· Compression couplings
· Slip couplings
3. Tee Fittings: Tee fittings have three ports and are used to combine or split flow. They can have:
· Same size outlets (straight tee)
· Different size outlets (reducing tee)
· Side outlet orientations (side-outlet tee)
4. Union Fittings: Unions allow easy connection and disconnection of pipes without rotating either pipe. This makes maintenance and system modifications much simpler, especially in tight spaces where HDPE pipes are commonly used.
