\otimes PIPECONNECTION

1.Preheat to 2 6 0 ^ { \circ } C

Connect the fusion tool to power up,and start operating only when the working temperature indicator light is on.

光

2.Clean pipe connection ends

Scrape off any burrs,level the end faces,and clean the surfaces of the pipes to be connected.

3.Makemarks

Usea caliperand a suitable pen to measure and mark the welding depth on the pipe ends which should meet the requirements in the table below.

4.Heat fusion

First insert the pipe fitting into the fusion mold. When the heating depth of the pipe fitting reaches 50 % of the specified depth,insert the pipe into the mold,and then push both the pipe and fitting to the bottom of the mold at the same time.

5.Socket fusion

Afterreaching thespecified time,immediately insert the pipe into the pipe fitting ina straight line without rotating.

6.Cooling and holding

Once the cooling time is reached, the welding iscomplete. (See the table below forspecific heating and cooling times.)

Note:The heating time given in this table should beadjusted according to the product manual of the fusion tool provided by our factory and the temperature of the construction environment.If the ambienttemperature is less than 5 ^ { \circ } \mathsf { C } ,the heating time should be increased by 50 % =
