Solvent Cement Jointing |
|||
All burrs from the internal and external surfaces should be removed. | The spigot should be marked with a pencil line at a distance equivalent to the socket depth. Clean the surface within the marked area. | ||
Apply uniform coat of solvent cement on the external surface of the pipe and a lighter coat on the internal surface of the fitting. | Insert the pipe end into the socket of the fitting and push it in upto the mark. |
||
Remove the excess solvent cement and hold the joint firmly in position for 30 seconds to dry. |
Rubber Ring Jointing |
|||
Chamfer the end of the pipe. Remove all burns, dust and dirt. | Apply lubricant on the external surface of the chamfered end of the pipe and on the rubber gasket. | ||
Check that the ring seal is in position in the housing. |
Push the pipe fully into the socket and mark the pipe depth in the socket with marker. |
||
Withdraw the pipe until the mark is 12 mm away from the socket before fixing. This gap between the pipe end and the socket register is very essential for thermal expansion/contraction. |
