PVC is a plastic material commonly used in plumbing projects. This pipe is strong and will not wear or leave an aftertaste like other traditional metal pipes. PVC pipes are connected at joints or fittings, which may have many joints on a fitting. It is often used in water supply, drainage, exhaust and other fields.
Connection method
PVC pipe fittings can be connected in two ways, one is to connect with glue and the other is to connect with threads. PVC pipes are glued at the joints to form a permanent fix. This “glue” is not a traditional glue because it actually forms a chemical bond with the inserted pipe. It can be difficult to remove the pipe from the fitting. However, sometimes we need to remove the glued pvc pipe fittings, perhaps because the pipe needs to be replaced or repaired. So, How to remove a pvc pipe fitting after it’s glued? Next, we will introduce it to you in detail.
How to remove a pvc pipe fitting after it’s glued?
1. Use a PVC pipe cutter or saw: If the diameter of the PVC pipe is large, you can use a PVC pipe cutter to cut the pipe. For longer pipes or narrower locations, you can use a saw to cut the pipe, but keep the cut flat to ensure the quality of subsequent connections.
2. Use a PVC cutter: Suitable for removing longer PVC pipes. Make a slit on the pipe, and pay attention to even force to avoid uneven cuts.
3. Use a hot air gun: If there is glue or other adhesives on the pipe, you can use a hot air gun to heat the adhesive and remove it after softening. Be careful to avoid overheating that affects the service life of the pipe.
4. Use the principle of thermal expansion and contraction: The glue will decrease in viscosity when it encounters heat. You can pour boiling water on the connection of the pvc pipe fittings or use a hair dryer to heat it, and then disassemble the connecting pipe fittings. This method will not affect the secondary use in the later stage.
5. Use PVC glue and ignite: Brush PVC glue on the inner wall of the pipe and ignite for 10 seconds, then immediately pry out the inner wall with a flathead screwdriver to separate the two pipes. This method is also suitable for the secondary use of pipes.
6. Use brute force: Although this method may damage the pipes, in some cases, you can try to separate the two connected pipes by using tools such as hammers, flathead screwdrivers and needle-nosed pliers.
When removing PVC pipes, you should choose the appropriate method according to the specific situation, and pay attention to safety in operation to avoid damaging the pipes or causing personal injury. For situations that require precise operation or have special requirements for pipes, it is recommended to seek help from professionals.
