Described prefabricated direct-buried crosslinked polyethylene reducing work insulating tube preparation method：It is prefabricated straight that the present invention is different from tradition
Insulating tube is buried, is taken with existing crosslinked polyethylene pipe for the work of original steel prefabricated direct-buried thermal insulation pipe, and by being crosslinked
The two-tube steel single tube return instead of original old traditional tube of polyethylene, the loop being had by oneself in a pipe is formed, will be handed over
After connection polyethylene pipe installs support, formed by the hdpe pipe of high-precision PE welding guns different angle prefabricated
The outer protection tube of direct-buried thermal insulation pipe crosslinked polyethylene work tube reducing, pipe ends are then installed into foaming guard seal and stayed
There is exhaust sieve, finally foamed by foaming machine spray foam, end face finishing processing is carried out after curing, be shape after the completion of the above
Into final finished.
Beneficial effects of the present invention：
1. the present invention uses crosslinked polyethylene as pipeline foundation raw materials, it is instrumentation tubes by crosslinked polyethylene pipe, is being crosslinked
The surface parcel polyurethane foam of polyethylene, outer protection tube use high density polyethylene materials, are fabricated to prefabricated direct-buried thermal insulation pipe friendship
Join polyethylene instrumentation tubes.
The convenience that the present invention installs is far longer than traditional insulation pipe, and thermal losses can be saved in terms of heat loss quality
34%, year cost-effective 34% can be reached in terms of operating cost, 34% can be reduced in terms of carbon emission amount is reduced, make
It can be met international standards minimum 30 years with life-span aspect, 54% can be saved in integrated operation cost.
The present invention selects high density polyethylene (HDPE) to have good leakage performance, rigidity as anticorrosive coat in outer protection tube
And hydraulic performance, having very high mechanical strength and excellent decay resistance, it can protect tubing transporting, install and making
Not by destruction caused by extraneous factor during.
The present invention is provided with two leakage alarm lines in heat-insulation layer, once seepage occurs for pipeline somewhere, passes through alarming line
Conduction, utilidor infiltration, the size of the accurate location of leak and leak magnitude can be shown in dedicated test instrument,
To notify inspection personnel to handle the pipeline section of leak rapidly, ensure the safe operation of heating network.
