PART B: HEATING OF PIPE AND FITTING
Heating of pipe and fitting
6. Push the end of the pipe, without turning, up to the marked welding
depth into the welding tool.
It is essential to observe the above mentioned heating times.
Pipes and fittings of the dimensions Ø 75 to 125 mm can only be
welded with welding device Art.-No. 50141 (or with machine Art.-No.
50147). On using the aquatherm- welding machine Art.-No. 50147 a
separate operating instruction has to be observed.
ATTENTION:
The heating time starts, when pipe and fitting have been pushed to the
correct welding depth on the welding tool. Not before!
PART B: SETTING AND ALIGNMENT
7. After the required heating time quickly remove pipe and fitting from
the welding tools. Joint them immediately, and without turning, until
the marked welding depth is covered by the PP- bead from the fitting.
ATTENTION:
Do not push the pipe too far into the fitting, as this would reduce the
bore and in an extreme case will close the pipe.
8. The joint elements have to be fixed during the specified assembly
time. Use this time to correct the connection. Correction is restricted
to the alignment of pipe and fitting. Never turn the elements or align
the connection after the processing time.
9. After the required cooling time the fused joint is ready for use.
The result of the fusion of pipe and fitting is a permanent material
joining of the system elements. Connection technique with security
for a life-time.
The fusion is subject to the following data
