Abstract
The invention relates to a large-diameter spraying winding-type prefabricated direct-burial insulating pipe. At present, a heat supply and cold supply pipe network and a petroleum and natural gas pipeline in China generally adopt the traditional prefabricated direct-burial insulating pipe, the production process has weaknesses, raw materials are excessively simple, great heat loss occurs on the aspect of the overall insulating performance, the service life of the insulating pipe cannot be effectively guaranteed, and the traditional prefabricated direct-burial insulating pipe has great defects on the aspect of energy conservation, environmental protection, economic benefit and the like. The large-diameter spraying winding-type prefabricated direct-burial insulating pipe comprises a working steel pipe (1), wherein the working steel pipe is connected with an insulating layer (2), and the insulating layer is connected with an outer protection pipe (3). The large-diameter spraying winding-type prefabricated direct-burial insulating pipe is mainly applicable to the fields such as large-sized urban heat supply and cold supply pipe networks and petroleum and natural gas delivery pipelines.
Description
technical field:
the present invention relates to a kind of heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, be particularly useful for the fields such as large size city heat supply, cooling pipe network and Oil and Natural Gas Transportation Pipeline.
background technique:
what current domestic heat supply, cooling pipe network and oil and gas pipeline generally adopted is all old-fashioned prefabricated direct-buried thermal insulation pipe, preparation process also exists certain defect, raw material are too simplified on using, integral heat insulation performance also exists great heat loss, thermal insulation pipe can not get effective guarantee working life, therefore this old-fashioned prefabricated direct-buried thermal insulation pipe also exists great problem in energy-conserving and environment-protective and economic benefit etc.
summary of the invention:
the object of this invention is to provide a kind of heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe.
above-mentioned object is realized by following technological scheme:
a kind of heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, its composition comprises: working steel tube, and the working steel tube described in it is connected with thermal insulation layer, and described thermal insulation layer is connected with outer pillar.
