How to connect PVC pipes safely and quickly is a very important issue，The connection of PVC pipes is generally divided into the following types
- Connection of two PVC pipe spigot ends
- The connection between the spigot end of the PVC pipe and the flange end
- Connection of spigot ends for PVC pipes and other material pipes
- Connection of spigot ends for PVC pipes of different size
How to connect spigot end and spigot end of the PVC pipes?
For PVC pipes with size≤OD40, we can use glue to stick them
- First prepare the hot melt adhesive, then use a saw or a cutter to cut the PVC pipe to size and remove the burrs.
- Then use a dry cloth to clean the dust, water and oil on the surface of the PVC nozzle.
- Spread the glue evenly on the outside of the spigot end and the inside of the socket end. The glue should be applied evenly, then quickly insert the nozzle of the spigot end into the socket end, press hard for a while, wait for the hot melt glue to cool, and the PVC pipe will be connected successfully, it will take at least two hours after the PVC water pipe is successfully connected before the water can flow normally.
For PVC pipes with size>OD 50, it is necessary to use ductile iron pipe fitting with gasket for connection, insert the PVC pipe into the socket end of ductile iron pipe fitting, and seal it through the self-locking of the rubber ring. Or use gibault joint or pipe coupling Connection, these two joints can be used to mechanically connect the PVC pipe, just insert the pipe into the sleeve, put the rubber ring in the correct position, and tighten the bolt to quickly connect the PVC pipe, and this connection can Suitable for high-pressure pipelines, gibault joints and couplings produced by judberd can be used on pipelines with a working pressure of 25 bar.

How to connect the spigot end of the PVC pipe and the flange from valves ,water meters etc pipe component?
Because we inevitably need to connect the PVC pipe and the flange , at this time the firm connection between the PVC pipe and the flange is very important. So we can connect the pvc pipe with the flange by flange adaptor, insert the pvc pipe into the socket end of the flange adaptor, and then connect the flange of the flange adaptor with other flanges from valves, water meters and other piping elements.

How to connect PVC pipes with PE pipes,Steel pipe,Ductile iron pipe etc other material pipes?
Sometimes we need to connect PVC pipes to PE pipes, PVC pipes to ductile iron pipes, PVC pipes to steel pipes,PVC pipe to GRP pipe,PVC pipe to AC pipe etc. Then we need to use step coupling, and insert the spigot ends of two pipes into the two ends of the step coupling, put the gasket in the correction position, tighten the bolts ,then they are connected.

How to connect PVC pipes of different sizes?
If you want to connect PVC pipes of different sizes, step coupling is also the right choice, we only need to insert the spigot ends of different sizes of PVC pipes into the two ends of step coupling. Put the rubber ring in the correct position and tighten the bolts to connect. Simple and fast, and the connection is strong.
Please note that if the ground is subsidence or unstable, consider using a coupling or step coupling with a locking function for connection to provide a firmer grip. Prevent the pvc pipe from coming out. In addition to the self-locking of the rubber ring, Restrained coupling also adds a locking ring or locking block to catch the pipe, so as to prevent the pipe from coming out due to internal pressure or ground movement which will easily cause leakage.
