Abstract
The utility model relates to a polyurethane foam fluid transportation pipeline with corrosion prevention and heat preservation, and belongs to the field of petroleum equipment. A pervious layer is arranged on the inner surface of the pipe body; a corrosion prevention layer is arranged on the outer surface of the pipe body; a heat preservation layer is arranged outside the corrosion prevention layer; a protection layer is arranged outside the heat preservation layer; the thickness of the corrosion prevention layer is 20 to 70 microns; the heat preservation layer is made of rigid polyurethane foamed plastic and the thickness of the heat preservation layer is 20 to 80 mm; and the protection layer is made of high-density polyethylene and the thickness of the protection layer is 2 to 5 mm. The polyurethane foam fluid transportation pipeline has the advantages that the corrosion prevention layer, the rigid polyurethane foamed plastic heat preservation layer and the high-density polyethylene protection layer all are combined with the pipe body tightly, with excellent integrity, so that the pipeline has excellent properties of pressure resistance, corrosion prevention, water prevention, heat preservation and the like, and service life of the pipeline is greatly prolonged; and a pipe ditch does not need to be laid during construction, and the pipeline can be buried underground directly, so that not only is cost saved, but also construction and installation are fast.
Description
Technical field
The utility model relates to oil equipment field, particularly a kind of polyurethane foam corrosion-resistant thermal insulation fluid-transporting tubing.
Background technique
The shortcomings such as the fluid lines such as Oil, Water, Gas are carried in the oil field at present, and ubiquity is anticorrosion, thermal insulation property is poor, pipeline occurs often because corrosion causes the accident of leakage.Adopt the products such as pitch is anticorrosion, rock wool heat-preservation, its corrosion-resistant thermal insulation effect is undesirable, therefore demands all good products of a kind of corrosion-resistant thermal insulation effect urgently, satisfies the needs that fluid is carried.
Summary of the invention
The purpose of this utility model is to provide a kind of polyurethane foam corrosion-resistant thermal insulation fluid-transporting tubing, the problems such as oil field transferring oil, water, feed channel poor corrosion resistance, working life be short have been solved, improved the corrosion resistance of oilfield fluid conveyance conduit, extended working life, be particularly suitable for buried and aerial pipeline.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
Polyurethane foam corrosion-resistant thermal insulation fluid-transporting tubing, comprise body 1, anticorrosive coat 2, thermal insulation layer 3, protective coating 4 and permeable formation 5, the internal surface of wherein said body 1 arranges permeable formation 5, outer surface arranges anticorrosive coat 2, described anticorrosive coat 2 outsides arrange thermal insulation layer 3, and described thermal insulation layer 3 outsides arrange protective coating 4.
Described anticorrosive coat 2 thickness are 20 ~ 70 μ m.
Described thermal insulation layer 3 adopts RPUF, and thickness is 20 ~ 80mm.
Described protective coating 4 adopts high density polyethylene (HDPE), and thickness is 2 ~ 5mm.
Described permeable formation 5 at the inwall of body 1, is to adopt chemical heat treatment method to infiltrate corresponding metal or nonmetalloid.
Owing to adopting RPUF, have a rate of closed hole high, thermal insulation properties is good, the characteristics such as water absorption rate is low adopt the high density polyethylene (HDPE) protective coating simultaneously, make heat preservation pipe prefabricated good integrity, have good resistance to compression, anticorrosion, insulation and water-proof performance, service life can reach more than 30 years.
The beneficial effects of the utility model are: RPUF has been widely used in the corrosion-resistant thermal insulation of pipeline, to extend the working life of pipeline.In general, can reach more than 30 years the working life of polyurethane foam corrosion-resistanting insulation pipe.Polyurethane foam corrosion-resistant thermal insulation fluid-transporting tubing is owing to adopting RPUF, have the characteristics such as rate of closed hole is high, thermal insulation properties good, water absorption rate is low, adopt simultaneously high density polyethylene (HDPE) to do protective coating, make heat preservation pipe prefabricated good integrity, have good resistance to compression, anticorrosion, insulation and water-proof performance, service life can reach more than 30 years.Simultaneously inwall infiltrates corresponding metal or nonmetalloid by the thermo-chemical treatment mode, has improved corrosion resistance, wear resistance, temperature tolerance and the performance such as anti-oxidant of pipeline.The RPUF thermal insulation layer of polyurethane foam corrosion-resistant thermal insulation fluid-transporting tubing, anticorrosive coat and high density polyethylene (HDPE) protective coating, combine closely with body, good integrity, make pipeline have the performances such as good resistance to compression, anticorrosion, waterproof and insulation, greatly extended the working life of pipeline.Make construction not need to lay pipe trench, but the pipeline direct-burried not only save investment, and construction and installation is quick in underground.Oil, gas, water is buried and aerial pipeline is most economical and optimal selection.
