polyurethane insulation coating of the present invention, adopt ring penta ball foaming technique, foaming machine spray foam foams, end face finishing process is carried out after slaking, this foaming technique environmental protection, the performance standard that energy-conservation, the aspect such as economy, safety, stability reaches prefabricated direct-buried thermal insulation pipe work pipe fitting, the environmental protection again of a kind of economy, not only energy-conservation but also reduce discharging, not only stable but also safe city cold and heat supply conveying pipe fitting.
the PE that the present invention adopts is equipped with polyurethane insulation coating in outer pillar inside, in described polyurethane insulation coating, alarming line, working steel tube are housed respectively, this structure can play insulating steel tube, extend the effect in steel pipe working life, 2 alarming line prevention pipes are housed simultaneously and there is seepage, described alarming line can detect the moisture that described polyurethane insulation coating internal work pipe fitting leaks out, simultaneously, also can detect that the moisture of polyurethane insulation coating inside is infiltrated in the outer pillar outside of PE, alarm function is played in alarming line conducting.
vertical working steel tube of the present invention and described horizontal operation steel pipe are reducers, and this structure can need according to pipeline the pipe connecting different bore.
the present invention effectively avoids the deficiency of traditional type prefabricated direct-buried thermal insulation pipe, and traditional type is all generally that the form of the outer pillar of employing one steel pipe one carries out Cemented filling, and must set up another pipeline formation loop while work can use; But the two-tube process engineering of prefabricated direct-buried thermal insulation pipe working steel tube just effectively avoids the foundation of this primary Ioops, because be equipped with two isometrical steel pipes in an outer pillar, effectively can form performance loop.
the intelligent prefabricated direct-buried thermal insulation pipe double steel tube pipe fitting reducing tee that the present invention adopts, save the not traditional prefabricated direct-buried thermal insulation pipe in heat loss aspect can compare, two-tubely to work simultaneously, form own circulation and more can effectively reduce cost reduction running cost, fully demonstrate the two-tube process engineering of prefabricated direct-buried thermal insulation pipe working steel tube not only energy saving but also economic environmental protection, more fully can ensure that working life of prefabricated direct-buried thermal insulation pipe.
