the prefabricated direct-buried crosslinked polyethylene of described intelligence two-tube reducing work thermal insulation pipe, described outer pillar is wrapped in insulation layer surface by the mode of parcel.
beneficial effect:
1. the utility model is different from traditional prefabricated direct-buried thermal insulation pipe, getting with existing crosslinked polyethylene pipe has replaced original seamless steel tube to be the work of prefabricated direct-buried thermal insulation pipe, and by the return of the original old-fashioned conventional tube of the two-tube replacement of crosslinked polyethylene, form loop own in a pipe, after crosslinked polyethylene pipe is installed support, the hdpe pipe of different amount is made to form the outer pillar of prefabricated direct-buried thermal insulation pipe crosslinked polyethylene work pipe fitting reducing by highi degree of accuracy PE welding gun, then pipe ends installed foaming guard seal and leave exhaust sieve, eventually pass foaming machine spray foam to foam, end face finishing process is carried out after slaking, namely final finished is formed after more than completing.
the utility model adopts crosslinked polyethylene to be pipeline foundation raw material, be working pipe by crosslinked polyethylene pipe fitting, at the surface of crosslinked polyethylene parcel polyurethane foam, outer pillar adopts high density polyethylene (HDPE) raw material, is made into prefabricated direct-buried thermal insulation pipe crosslinked polyethylene working pipe.
the convenience that the utility model is installed is far longer than traditional type thermal insulation pipe, heat loss 34% can be saved in heat waste consumption, year cost-saving 34% can be reached in operating cost, can 34% be reduced in minimizing carbon emission amount, can meet international standards in working life, in 30 years minimum life-spans, can 54% be saved at integrated operation cost.
the utility model outside pillar is provided with high density polyethylene (HDPE) anticorrosive coat; there is good leakage performance, rigidity and hydraulic performance, there is very high mechanical strength and excellent decay resistance. it can protect tubing in transportation, installation and use process not because of destruction that extraneous factor causes.
the utility model is provided with two leakage alarm lines in thermal insulation layer, once there is seepage in pipeline somewhere, by the conduction of alarming line, just the size of insulation pipe infiltration, the accurate location that leaks and leak magnitude can be demonstrated in dedicated test instrument, so that notice inspection is oozed personnel and processed rapidly the pipeline section leaked, ensure the safe operation of heating network.
