Adhesive differences of PVC water supply pipe and fitting with different external diameters
The difference between the outer diameter of PVC-U water supply pipe and fitting is very big, and the external diameter bonding method of different pipe specifications is also different, so we need to find out the difference between them to avoid water leakage when using.
Adhesive difference of outer diameter of PVC-U water supply pipe and fitting
If the outer diameter is greater than or equal to 100mm, rubber ring will be used to connect,
If the size of outer diameter is less than 100mm, the method adopted is different, and the method of bonding joint will be adopted
Of course, there is also a way of using union to connect.
In a word, different PVC-U water supply pipe and fitting will have different methods of use.
There are many specifications of PVC water supply pipe and fitting, and the price will be different. The largest pvc pipe and fittings reach nearly 200 mm. Because of the use of many environments, the specification requirements for the outer diameter will be different. There is a big difference in price and wall thickness, which is due to different environmental requirements.
Points for attention before bonding PVC pipes and fittings of different specifications:
In general, when the PVC pipes and pipe fittings with diameter larger than 100mm are bonded, the following three points need to be done:
① Wipe the bonding area clean
② Use the rubber ring as the interface, and check whether the used rubber ring is qualified
③ Arrange personnel to invert the spigot of the pipe into a 45 degree angle
When the outer diameter of PVC water supply pipes and pipe fittings is small, when solvent is used for bonding, some preliminary work needs to be done, that is, chamfering the spigot mouth, then a slope type interface will be formed, so that it will be watertight and can be bonded firmly.
