4. Preparations
Before the installation start, following preparations must be made:
• If possible check that the still pipe is empty and remove any obstructive objects.
• Make sure the still pipe is vertical within 0.3° (0.1 m over 20 m).
• Arrange for a fixed point, for example a crane or a tripod, approximately 3.5 meters (10 ft) above
the still pipe nozzle. Attach a tackle to facilitate lowering the insertion pipes into the still pipe.
----------------------------------------------------------------------------------------------------------------------- Note! The total weight of the pipes will be 75-150 kg depending on how many pipes used.
Each pipe weighs approximately 25 kg.
-------------------------------------------------------------------------------------------------------------------------
• Measure the height of the still pipe. Add 200 mm (~8”) and cut the top pipe to a proper length.
• Mark a centre line along all insertion pipes to make it possible to vertically align the pipes.
Figure 1. Bottom pipe with Wire ring and Bottom pipe legs
• Slip a wire through the wire ring on the lower part of the bottom pipe.
The wire is used for inserting the temperature sensors into the still pipe.
• Hang the middle of a rope with a length extending 40 meter (130 ft) between the legs on the bottom
pipe. Do not attach the rope to any of the legs.
