PVC pipes are used widely in construction, infrastructure, agriculture, and other sectors. Their benefits, like affordability, lightweight, and durability with low maintenance needs, make them highly desirable.
However, to form a strong and reliable pipeline, PVC pipes fitting plays an equally important role as the pipes themselves. Fittings connect pipe segments together and allow changes in flow direction. They ensure the integrity of the entire piping system. This pipe fittings guide explores common PVC fitting types that help achieve different pipe configurations for diverse installation needs.
Common PVC Fitting Types
PVC fittings come in different shapes and sizes. They facilitate the installation of PVC pipes in various applications. Some of the common PVC fitting types used include:
1. Couplings and Unions
These types of pipe fittings PVC are used to join two pipe segments end-to-end or join misaligned pipes. They provide flexibility and allow for easy installation/disassembly when needed. They are available in different pressure classes and material varieties to suit installation needs.
2. Elbows
Elbows allow connecting two pipe segments running at right angles to change flow direction. Degrees of elbows can be 45, 90, or 180. Elbows are often used to modify direction where space is limited.
3. Tees
Tees provide connections for introducing or extracting liquids from the main pipeline. They branch the flow in three directions. These PVC fitting types enable drawing samples or draining sections of the piping arrangement.
4. Crosses
Crosses are similar to tees but connect pipelines in four opposite directions rather than three. These PVC fitting types permit dividing or combining fluid streams along four axes.
5. Caps and Plugs
These PVC fitting types are used to seal off opened ends temporarily or permanently during installation, transportation, or storage. They protect the pipe interior from dirt and moisture ingress.
6. Adapters
Adapters connect pipes or fittings of two different sizes. They either reduce the size or increase it. These PVC fitting types enable the joining of differently sized pipes smoothly.
7. Bushings
Bushings are short pipe fittings similar to adapters. However, they are used specifically to enlarge pipe sizes. They transition pipes to larger sections incrementally.
8. Nipples
Nipples are short pipe segments. They are used to extend and connect pipes coming out of a fitting like unions, couplings, or valves. These PVC fitting types allow flexible positioning of attachment points.
9. Flanges
Flanges provide connections to attach pipes, fittings, or pipes to other flanged devices like pumps and valves. Bolted joints ensure a secure connection. Flanges help in the assembly and dismantling of pipe segments.
How to Enhance the Sealing of PVC Pipes?
To prevent leaks and extend the system’s lifespan, proper installation and joining are important. Follow these guidelines for the best results:
1. Choose the Appropriate Joint Method
Solvent welding provides the best seal for pressure applications. Screwed and compression joints are for low-pressure drainage systems. Welded sockets are an option too. They can withstand higher pressure ratings compared to mechanical fittings.
2. Ensure a Clean Surface Before Installation
Rid pipe and fitting interiors of dirt, debris, and moisture. They can weaken the joint bond. Scraping and washing remove contaminants for a fresher bonding area. Dry thoroughly before applying cement.
3. Use PVC Primer and Cement
Apply PVC primer before cement to soften surfaces for a stronger weld. Match cement type to PVC pipes fitting material and diameter. Proper application procedure helps create an optimum seal at the joint.
4. Testing and Maintenance
Pressure test installations and inspect periodically for any issues. Timely repairs improve the long-term performance of the piping system. Routine checks can identify potential problem areas for protective resolution.
