Description
Technical field
It the utility model is related to petroleum transportation facility field, more particularly to a kind of antifreeze fireproof petroleum transportation pipe.
Background technology
Pipeline transportation is the defeated mode by the use of pipeline as a kind of long distance delivery liquids and gases goods and materials of means of transport, is
A kind of specially means of transportation from grown place to market transfer oil, coal and chemical products, is line haul in consolidated delivery net
Special part, but dry weather or it is cold when, easily break down, potential safety hazard be present.
Utility model content
The purpose of this utility model is to provide a kind of antifreeze fireproof petroleum transportation pipe, to solve above-mentioned technical problem.
The utility model uses following technical scheme to achieve the above object：
A kind of antifreeze fireproof petroleum transportation pipe, including delivery tube and protection pipe, the protection pipe are welded on outside delivery tube
The ring flange for connecting other adjacent delivery tubes is welded at layer, the delivery tube both ends, and the flange panel surface opens up bolt hole,
The protection pipe surface scribbles the fireproof coating of protection delivery tube, and the insulating tube for being incubated to delivery tube, the insulation is inscribed
Tube outer surface is glued insulation and filled, sealing welding air inlet pipe and escape pipe on insulating tube, and the air inlet pipe and escape pipe stretch out and protected
Pillar, the air inlet pipe are welded on insulating tube front end, and surface opens up air admission hole, and the escape pipe is welded on insulating tube rear end, lead to
Cross the air inlet pipe that pipeline connects adjacent delivery tube, the conveying between delivery tube for hot gas.The protection pipe and insulating tube
Between addition prevent the heat-insulated filling of high temperature failure delivery tube.
Preferably, the protection pipe, delivery tube and flange disk material are Q235 steel.
Preferably, the insulation is filled with rock wool, described heat-insulated to be filled with composition silicate.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, easy to disassemble, prevents
Freeze fire prevention；When preparing, by the ring flange on delivery tube top, adjacent delivery tube is linked together, transported, day
During gas cold.Waste gas in boiler or heating is entered into insulating tube by air inlet pipe, whole delivery tube is wrapped up, prevents delivery tube
Interior oil solidification, and when external high temperature is prevented in protection pipe, the oil in delivery tube is influenceed, safety and environmental protection, preferably promoting makes
With.
Brief description of the drawings
Fig. 1 is the structure chart of this novel anti-freezing fireproof petroleum transportation pipe.
Fig. 2 is the cut-away view of this novel anti-freezing fireproof petroleum transportation pipe.
In figure：1st, bolt hole, 2, air inlet pipe, 3, protection pipe, 4, escape pipe, 5, ring flange, 6, delivery tube, 7, air admission hole,
8th, insulating tube, 9, insulation filling, 10, heat-insulated filling.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of antifreeze fireproof petroleum transportation pipe, including delivery tube 6 and protection pipe 3, the protection pipe 3 are welded
The outer layer of delivery tube 6 is connected on, the ring flange 5 for connecting adjacent delivery tube 6, the table of ring flange 5 are welded in the both ends of delivery tube 6
Face opens up bolt hole 1, and the surface of protection pipe 3 scribbles the fireproof coating of protection delivery tube 6, is inscribed for being incubated to delivery tube 6
Insulating tube 8, the outer surface of insulating tube 8 is glued insulation filling 9, sealing welding air inlet pipe 2 and escape pipe 4 on insulating tube 8, institute
State air inlet pipe 2 and escape pipe 4 stretches out protection pipe 3, the air inlet pipe 2 is welded on the front end of insulating tube 8, and surface opens up air admission hole 7, institute
State escape pipe 4 and be welded on the rear end of insulating tube 8, the air inlet pipe 2 of adjacent delivery tube is connected by pipeline, for hot gas in adjacent fortune
Conveying between defeated pipe 6, the heat-insulated filling 10 for preventing high temperature failure delivery tube 6 is added between the protection pipe 3 and insulating tube 8.
Utility model works principle：When preparing, by the ring flange 5 on the top of delivery tube 6, adjacent delivery tube 6 is connected
It is connected together, is transported, during cold weather.Waste gas in boiler or heating is entered into insulating tube by air inlet pipe 2
8, whole delivery tube 6 is wrapped up, prevents the oil in delivery tube 6 from solidifying, beneficial to the smooth outflow of oil, and is prevented in protection pipe 3
Only during external high temperature, the oil in delivery tube 6, safety and environmental protection are influenceed.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
