aquatherm- weld-in saddles are available for pipe outer diameter of 40
- 630 mm.
Weld in saddles are used for
•
branch connections in existing installations
•
the substitution of a reduction-tee
•
branch connections in risers
•
sensor wells, etc.
1. Before starting the welding process, check whether the aquatherm-
welding devices and tools comply with the requirements of "Fusion Part A".
2. The first step is to drill through the pipe wall at the intended outlet point
by using the aquatherm- drill (Art.-No. 50940-50956).
3. IMPORTANT!
Only the oxgen barrier layer of the aquatherm blue pipe OT Art.-No.
2170708-2170138 must be removed with the mentioned aquatherm
special peeling drills mentioned in the table beside.
For this the special peeling drill is inserted into the bore hole and
swaied 2-3 times with light pressure and low rotating speed between
the pipe walls until the oxygen barrier layer is completely peeled off.
Remove burrs, debris and other dirts with a chamfering tool or the
aquatherm cleaning wipes. Do not touch the peeled surface any more
and protect it from new pollution.
When using aquatherm green pipe - stabi composite pipes remove
the rest of the aluminium remaining at the bore hole with the
aquatherm- chamfering device.
4. The welding device / saddle welding tool must have reached the
required operating temperature of 260 °C (check with reference to
"Fusion Part B, item 2").
5. The welding surfaces have to be clean and dry.
6. Insert the heating tool on the concave side of the weld in saddle tool
into the hole drilled in the pipe wall until the tool is completely in
contact with the outer wall of the pipe. Next the weld-in saddle tool is
inserted into the heating sleeve until the saddle surface is up against
the convex side of the welding tool. The heating time of the elements is
generally 30 seconds.
7. After the welding tool has been removed, the weld-in saddle tool is
immediately inserted into the heated, drilled hole. Then the weld-in
saddle should be pressed on the pipe for about 15 seconds. After being
allowed to cool for 10 minutes the connection can be exposed to its
full loading. The appropriate branch pipe is fitted into the sleeve on the
aquatherm- weld-in saddle using conventional fusion technology.
By fusing the weld-in saddle with the pipe outer surface and the
pipe inner wall the connection reaches highest stability.
