Abstract
The utility model relates to a polyurea anticorrosion insulated pipeline for oil field transfusion, providing an impact-resistant moisture-resistant anticorrosion insulated pipeline, which is characterized in that the temperature-resistant epoxy resin coating is coated outside a pipeline (1) as an anticorrosive layer (2), a polyurethane foam insulation layer (3) and a polyurea protective layer (4). The utility model has the advantages that the utility model has the advantages of simple equipment, convenient operation and not being affected by the size of the pipe diameter due to that in the manufacturing technique the NUKOTE polyurea anticorrosion insulated pipeline uses a spray gun to spray foam and polyurea coating; the thermal insulation materials can choose different materials according to the need, such as polyurethane, glass wool or rock wool; the applicable temperature range is from -40 degree to 750 degree; the thicknesses of the insulation layer and the protective layer can be determined at will; the polyurea coating as the protective layer has good impact-resistant performance, good moisture-resistant performance, excellent chemical-resistant performance, ultraviolet resistance and strong bonding strength with the polyurethane insulation layer.
Description
(1) technical field:
The utility model relates to the polyureas corrosion-resistanting insulation pipe of oil field transfusion.
(2) background technique:
The conveying of all fluids all will be carried with pipeline in water in life, production and the heating, generally all is the metallic steel pipeline.Mode of execution has two kinds: a kind of is built on stilts or on the ground, year in and year out through wind and weather and oxidation, some pipeline generation rust corrosions also will be bored a hole for a long time afterwards.Another kind is to be embedded in undergroundly, helps surface construction and insulation, but also can rust corrosion after long-term, shortens the pipeline spreadable life.Bring influence and stopping production then can for life and production if generation is bored a hole, the while is befouling environment again, makes troubles to maintenance.It relates to the Important Project of decades the laying of pipeline, avoid corrosion, is located in ice box and also will considers insulation, any problem do not occur after long-term the use.
(3) model utility content:
Technical problem to be solved in the utility model is at the problem that exists in the background technique, and the polyureas corrosion-resistanting insulation pipe that a kind of impact resistance, moisture resistance can be high is provided.
The invention for solving the technical problem can reach by following technical solution: apply the heatproof epoxy resin coating and make anticorrosive coat, polyurethane foam insulation layer, polyureas protective layer outside pipeline.
Adopt NUKOTE (knob section) polyureas corrosion-resistanting insulation pipe to adopt spray gun spray foam and carbamide paint on production technology, equipment is simple, and is easy to operate, is not subjected to the influence of caliber size; Thermal insulating material can be selected different materials as required for use, as polyurethane, glass wool or rock wool etc.The Applicable temperature scope is-40 ℃～750 ℃; Thermal insulation layer and protective layer thickness can be determined arbitrarily.Carbamide paint has good impact resistance as protective layer, moisture resistance can and good resistance to chemical corrosion and anti-ultraviolet aging and with characteristics such as the polyurethane insulation coating bonding strength is good.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the utility model adaptive temperature scope :-40 ℃～750 ℃; The thickness of thermal insulation layer and protective layer can be determined arbitrarily according to user's needs; Good impact resistance, moisture resistance energy and good resistance to chemical corrosion are arranged; It is not influenced by ambient temperature to construct, and can construct in-40 ℃ or moist environment; Thermal insulation layer and protective layer all can spray prefabricated, dual-use, the on-the-spot anticorrosion seamless effect of pipeline one that reaches; Anti-ultraviolet property is preferably arranged, be applicable to various weather conditions.
(4) description of drawings:
Accompanying drawing is the utility model sectional structure chart.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing, coating heatproof epoxy resin coating is made anticorrosive coat 2, polyurethane foam insulation layer 3 and polyureas protective layer 4 outside pipeline 1.
Adopt NUKOTE (knob section) polyureas (anticorrosion) insulation pipe on the water filling engineering in oil field and corrosion-resistant thermal insulation engineering, to be applied; this product is that the steel pipe outer surface used of conveyance fluid is after sand blast; the spraying epoxy coating; make anticorrosive coat 2 as coating such as H88, H87 liquid epoxy coating and D518 heat-resistance type epoxies; spray polyurea coating forms protective layer 4 outside forming thermal insulation layer 3 then, forms insulation pipe.This product processes is simple, easy construction, and the product antiseptic property is good, and site operation can be realized the effect that the pipeline one is seamless.
Claims (1)
1, a kind of polyureas corrosion-resistanting insulation pipe that relates to contains pipeline (1), it is characterized in that: coating heatproof epoxy resin coating is made anticorrosive coat (2), polyurethane foam insulation layer (3) and polyureas protective layer (4) outside pipeline (1).
