Abstract
The utility model discloses a kind of insulation constructions for the welding of cold environment pipeline, including pipeline body, muff is arranged in the joint close to pipeline body, heating tape, the fully wrapped around heating tape of muff are arranged between muff and the tube wall of pipeline body.Muff and heating tape can be maintained for a long time the preheating temperature of weld, postwelding, the postwelding temperature of weld will not rapid cooling get off, it is possible thereby to improve quality of weld seam molding, in weld, the surface brittleness of pipeline is greatly diminished, at this time, after carrying out anticorrosive paint construction operation, viscosity between anticorrosive paint and pipeline is strong, and anticorrosive paint is not easily to fall off, can form erosion resistant coating on the surface of pipeline well, and then the anti-corrosion effect of weld is improved, solve the problems, such as under cold environment that pipeline weld anti-corrosion effect is poor, poor welding quality.
Description
Technical field
The utility model is related to pipelines to weld corrosion-resistant field, particularly a kind of heat preservation knot for the welding of cold environment pipeline
Structure.
Background technology
In cold environments, the anticorrosive construction operation of pipeline is the problem of people compare headache all the time, in cold ring
Under border, when being welded to pipeline configuration, at this time since steel pipe brittleness is big, after being welded to weld, welding quality is general
Poor, anticorrosive paint is not easy firmly to be bonded in weld during postwelding coating anticorrosive paint, thus causes erosion resistant coating bonding poor, easily
It comes off, anti-corrosion effect is had a greatly reduced quality.
Utility model content
The goal of the invention of the utility model is：In view of the above problems, it provides a kind of for cold environment pipeline
The insulation construction of welding, to solve existing deficiency.
The technical solution adopted in the utility model is as follows：A kind of insulation construction for the welding of cold environment pipeline, including
Pipeline body, which is characterized in that in the tube wall that muff, muff and pipeline body are arranged with close to the joint of pipeline body
Between be arranged with heating tape, the fully wrapped around heating tape of muff.
Due to the setting of above structure, the muff of setting and heating tape can make the preheating temperature of weld keep longer
Time, postwelding, the postwelding temperature of weld will not rapid cooling get off, it is possible thereby to improve quality of weld seam molding, in weld,
The surface brittleness of pipeline is greatly diminished, at this point, after carrying out anticorrosive paint construction operation, the viscosity between anticorrosive paint and pipeline
By force, anticorrosive paint is not easily to fall off, can form erosion resistant coating on the surface of pipeline well, and then improves the anti-corrosion effect of weld
Fruit solves the problems, such as under cold environment that pipeline weld anti-corrosion effect is poor, poor welding quality.
Preferably, the heating tape is silica gel heat tape.
Preferably, the muff is continuous for external application heating.
Further, the overlay area of the muff connects with the welding region of the connector of pipeline body.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：The muff of setting and
Heating tape can be maintained for a long time the preheating temperature of weld, postwelding, and the postwelding temperature of weld will not be under rapid cooling
Come, it is possible thereby to improve quality of weld seam molding, in weld, the surface brittleness of pipeline is greatly diminished, at this point, carrying out anti-corrosion painting
After expecting construction operation, the viscosity between anticorrosive paint and pipeline is strong, and anticorrosive paint is not easily to fall off, can be well in the table of pipeline
Face forms erosion resistant coating, and then improves the anti-corrosion effect of weld, solve pipeline weld anti-corrosion effect under cold environment it is poor,
The problem of poor welding quality.
Description of the drawings
Fig. 1 is a kind of insulation construction schematic diagram for the welding of cold environment pipeline of the utility model.
It is marked in figure：1 is pipeline body, and 2 be connector, and 3 be muff, and 4 be heating tape, and 5 be welding region.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, a kind of insulation construction for the welding of cold environment pipeline, including pipeline body 1, close to pipeline
Muff 3 is arranged at the connector 2 of ontology 1, heating tape 4, the guarantor are arranged between muff 3 and the tube wall of pipeline body 1
3 fully wrapped around heating tapes 4 of temperature set.
In the above-described embodiments, when the muff 3 of setting and heating tape 4 can make the preheating temperature of weld keep longer
Between, postwelding, the postwelding temperature of weld will not rapid cooling get off, it is possible thereby to improve quality of weld seam molding, in weld, pipe
The surface brittleness in road is greatly diminished, at this point, after carrying out anticorrosive paint construction operation, the viscosity between anticorrosive paint and pipeline
By force, anticorrosive paint is not easily to fall off, can form erosion resistant coating on the surface of pipeline well, and then improves the anti-corrosion effect of weld
Fruit solves the problems, such as under cold environment that pipeline weld anti-corrosion effect is poor, poor welding quality.
Mode is preferably carried out as one kind, the heating tape 4 is silica gel heat tape.Further, the muff 3
Preferably external application heating is continuous；The overlay area of the muff 3 connects with the welding region 5 of the connector 2 of pipeline body 1.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
