HEATING MAIN MONTAGE INSTRUCTIONS CV4.04
In case of major external top loads (for example when it is located underneath or is
crossing auto road) over the pipes is placed reinforced concrete plate for better load
distribution. Another possible protection for preinsulated pipes is putting protectors onto
the pipe and pushing it through already existing corrosion resistant pipe. Protectors are
base relief on PE casing, which protect the casing from damages while moving axially.
The length of the load distributor should exceed the length of the pipe section to be
protected at least 1 m.
Pipes before welding can be place directly in the trench or on supports above the trench.
Pipes in the trench are placed on supports or on sand cushion.
If pipes are located above the trench
then after the welding, hydraulic
testing and placement of connecting
sleeve pipes should be lowered into
the trench using lifting straps.
