Abstract
The utility model belongs to buried heat-insulating anti-corrosion steam pipes used in oil fields, and particularly relates to an improved buried heat-insulating anti-corrosion steam pipe. Heat-insulating layers and aluminium foil layers, which are made of continuously wound ribbon nanometer composite heat-insulating felt, are arranged on the outer wall of the steam steel pipe in sequence from inside to outside; the insulating layers and the aluminium foil layers are arrayed in a staggered manner; and an anti-corrosion layer formed by winding yarn on impregnated plexiglass is arranged on the outmost aluminium foil layer. The utility model has the advantages of good heat insulation effect, low heat radiation loss, reasonable structure of the anti-corrosion layers, good effect, prolonged service life of heat-insulating pipelines, and remarkable economic benefits.
Description
Technical field
The utility model belongs to oil field ground insulation antiseptic steam tube, the particularly improved ground insulation antiseptic steam tube that buries.
Background technique
The structure of the insulation steam tube of existing Oilfield using is: with thickness is two plots of expanded perlites watt of 100mm, is buckled on the steam tube back with the iron wire binding, and appearance is poured into a mould asphalt anti-corrosion.But owing to perlite watt combination all can't leave the gap by jam-packed, behind the logical steam, the steel pipe elongation of expanding has more strengthened the gap of two perlites watt.Therefore the overheated gas of steam tube appearance is easy to scurry out, thereby boiling hotization anticorrosive coat makes it lose antisepsis.Outside then steam with heavy corrosion or sewage are easy to penetrate into the appearance of high-temperature steam pipeline and cause the pipeline heavy corrosion.The general 2-3 of this type of steam insulation pipeline just will change once.Therefore long-time overheated gas is scurried outward, and thermal loss is excessive, causes heat insulation effect poor.
Summary of the invention
The purpose of this utility model is to provide a kind of improved ground insulation antiseptic steam tube that buries, high insulating effect not only, and radiation loss is little, and anti-corrosion layer structure is reasonable, and favorable anti-corrosion effect has prolonged working life of hot insulated line, remarkable in economical benefits.
The purpose of this utility model is achieved in that a kind of improved ground insulation antiseptic steam tube that buries, uniform successively from inside to outside the setting by banded nano composite heat insulation felt twined thermal insulation layer and the aluminium foil layer that constitutes continuously on the outer wall of steam steel pipe, thermal insulation layer and aluminium foil layer space are staggered, and are being provided with on outermost aluminium foil layer by the impregnation plexiglas and are twining the anticorrosive coat that yarn constitutes.
The thermal insulating material of thermal insulation layer of the present utility model is banded nano composite heat insulation felt, and the thermal conductivity normal temperature of this insulation quilt is 0.014W/mk, is 0.035W/mk in the time of 400 ℃; And the thermal conductivity of conventional thermal insulating material is 0.15W/mk.Thermal insulation layer the layer with layer between accompany reflective aluminium foil, thermal insulation layer be positive and negative two directions close around, can not leave a bit gap.It is very good to detect effect at the oil field thermal insulation pipe.The utility model insulation layer thickness 20mm, and the insulation layer thickness of conventional steam insulation pipe is 100mm.Measured the utility model hull-skin temperature is than also low 3 ℃ of routines.Under equal conditions, record radiation loss and descend 38.9%.
Appearance anticorrosive coat resin glue is new-type configuration high-temperature-resistant epoxy resin.During winding, glass is woven on Stetch Wrapping Machine after twining yarn gumming.Glass twines yarn and is wrapped on the aluminium foil of thermal insulation layer appearance, has received very desirable antiseptic effect.Show that according to interrelated data the life-span can reach 20 years.And the scene is when making steam pipe line, and the anticorrosive coat surface at two ends on the pipe that twines earlier in factory goes out the spiral sulculus with machined into, and the alligatoring appearance is to guarantee the mending adhesive strength that twines anticorrosive coat at the scene.
The utility model is high insulating effect not only, and radiation loss is little, and anti-corrosion layer structure is reasonable, and favorable anti-corrosion effect has prolonged working life of hot insulated line, remarkable in economical benefits.
