Abstract
The invention relates to a working steel tube double-tube tube fitting bend of an intelligent prefabricated direct buried heating insulating tube and a manufacturing method. At present, a traditional prefabricated direct buried heating insulating tube in China generally has the defects of being large in heat loss amount, high in operation cost, large in carbon discharge amount, short in tube service life and the like. The working steel tube double-tube tube fitting bend of the intelligent prefabricated direct buried heating insulating tube comprises a polyethylene outer protecting tube (1), a polyurethane protecting layer (3) is arranged in the polyethylene outer protecting tube (1), a double-tube working steel tube (4) is wrapped by the polyurethane protecting layer (3), an alarm line (2) is arranged in the polyurethane protecting layer (3), and a supporting support plate (5) is arranged between the polyethylene outer protecting tube (1) and the double-tube working steel tube (4). The manufacturing method is applied to manufacturing the working steel tube double-tube tube fitting bend of the intelligent prefabricated direct buried heating insulating tube.
Description
technical field:
the present invention relates to the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube and making method.
background technique:
at present, the defects such as domestic traditional prefabricated direct-buried thermal insulation pipe ubiquity that heat waste consumption is large, operating cost is high, carbon emission amount is large, pipeline working life is short.Traditional type prefabricated direct-buried thermal insulation pipe is all that the form of the outer pillar of employing one steel pipe one carries out Cemented filling, another pipeline formation loop must be set up can use while work, 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 performance loop can be formed.
summary of the invention:
the object of this invention is to provide the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube and making method.
above-mentioned object is realized by following technological scheme:
the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube; its composition comprises: polyethylene outer protective pipe; in described polyethylene outer protective pipe, there is protective polyurethane layer; described protective polyurethane layer wraps up one group of two-tube working steel tube; in described protective polyurethane layer, there is alarming line, there is between described polyethylene outer protective pipe and two-tube working steel tube supporting bracket plate.
the described two-tube pipe elbow of intelligent prefabricated direct-buried thermal insulation pipe working steel tube, described working steel tube internal diameter is 20-1200mm, and described protective polyurethane layer thickness is 30-200mm, and described outer pillar thickness is 1-30mm.
the making method of the described two-tube pipe elbow of intelligent prefabricated direct-buried thermal insulation pipe working steel tube, original seamless steel pipe has been replaced to be the working steel tube of prefabricated direct-buried thermal insulation pipe with two-tube the getting of existing crosslinked polyethylene, 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 elbow 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.
beneficial effect of the present invention:
1. the present invention save heat loss aspect just not traditional prefabricated direct-buried thermal insulation pipe can compare, two-tubely to work simultaneously, form own circulation and more can effectively reduce cost reduction running cost, reduce carbon emission amount, 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.
between polyethylene outer protective pipe of the present invention and working steel tube, there is supporting bracket; to its intensity of working steel tube and the mutual support reinforcing of polyethylene outer protective pipe; the use more steadily simultaneously decreasing material is installed; in protective polyurethane layer, there is alarming line, when occurring alarm function to be played when leaking.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is plan views of the present invention.
