2.5. Work Methodology

In order to install domestic PPR-C cold and hot water piping, the following work

sequence to be implemented:

2.5.1 Get welding machine and suitable welding sockets ready. Sockets should be

cleaned before assembly.

2.5.2 Turn on the welding machine by setting it to 260 C. You can start welding when

termostat light turns off when it reaches to 260 °C.

2.5.3 Be careful to have the welding surfaces of pipes and fittings clean. If needed, the

surfaces should be cleaned with alcohol and dry with a clean cloth.

2.5.4 Pipes should be cut to appropriate measurement and vertical to pipes axis.

2.5.5 Te height of the pipe's welding area should be equal to the depth of the welding

and should be signed. Longer lenght can cause smaller radium and accumulation,

shorter lenght can cause space and less welding area.

2.5.6 The pipe and fittings inserted info the welding socket should not be turner.

2.5.7 The heating time should be calculated according to the table at the right side.

2.5.8 Pipe and fittings should be heated at the same time, at the end of the heating time,

should be removed from the sockets at the same time rapidly and connectes in the

same axis without turning but pusting to each other.

2.5.9 After theconnection, wait till the cooling time.

2.5.10 Heating time (If ambient temperature is below +5°C, heating duration must be

increased at a rate of 50%)
