Abstract
Heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe.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.A kind of heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, its composition comprises: working steel tube (1), and described working steel tube is connected with thermal insulation layer (2), and described thermal insulation layer is connected with outer pillar (3).The utility model is mainly used in the fields such as large size city heat supply, cooling pipe network and Oil and Natural Gas Transportation Pipeline.
Description
technical field:
the utility model relates to a kind of heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, is applicable to 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.
model utility content:
the purpose of this utility model 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 described working steel tube is connected with thermal insulation layer, and described thermal insulation layer is connected with outer pillar.
described heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, described working steel tube is helical arc welded steel pipe, and described outer pillar is polyethylene layer.
described heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, described working steel tube internal diameter is 200-1200mm, and described insulation layer thickness is 30-200mm, and described outer pillar thickness is 1-30mm.
described heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe, the mode that described outer pillar is wound around by spraying is wrapped in insulation layer surface.
beneficial effect:
1. the utility model is the large scale prefabricated direct-buried insulated pipe of first production method production adopting jet printing type to be wound around domestic at present, adopt first jet printing type polyurethane foam technology domestic, make the various performance parameters of thermal insulation layer and technical order reach international highest standard, this point can not exist on old-fashioned prefabricated direct-buried thermal insulation pipe.
the purpose of this utility model is exactly to effectively ensure that prefabricated direct-buried thermal insulation pipe creates larger breakthrough in energy-saving and environmental protection, economic dispatch, heavy caliber jet printing type winding type prefabricated direct-buried thermal insulation pipe effectively solves the ubiquitous technical barrier of old-fashioned prefabricated direct-buried thermal insulation pipe, preparation process have employed spraying winding technology advanced in the world and ensure that prefabricated direct-buried thermal insulation pipe there will not be any quality problems at first working procedure i.e. core process.
