Description
Technical field：
The present invention relates to heat supply, cooling, ship domain energy conveyance conduit technical field, especially design is a kind of has ripple
The insulating tube and production method of line outer protection tube.
Background technology：
At present, the utilidor that the whole nation uses, the instrumentation tubes of the insulating tube of small-bore polyurethane heat-insulation polyethylene outer protective pipe
Road road is substantially steel, hard plastic material, and flexibility is low, it is impossible to carry out low-angle turning, and polyethylene of outer protection tube use etc.
Plastic material, since outer protection tube is straight pipeline, bendability deficiency, after bending by force, interior turn of bilge position squeezes out fold, and the back of the body is curved
Position is stretched or even tensile fracture, and service pipe road is caused to damage, and keeps the temperature damage layer.
Also most of small-bore pipeline, is all using service pipe outsourcing plastic cement cotton, then winds plastic band, caused
Problem is that pipeline truncation surface is more, and interface is more, and heat preservation is bad, and the high consumption wave of the energy is being caused into access customer incity is finally a bit of
Take, and pipeline construction is coarse, causes the tip pipe network service life low.
The content of the invention：
The object of the present invention is to provide a kind of insulating tubes and production method with ripple outer protection tube.
Above-mentioned purpose is realized by following technical scheme：
A kind of insulating tube with ripple outer protection tube, composition include：Service pipe, the service pipe inner surface apply
Corrosion-inhibiting coating is covered, the service pipe outer surface is coated with heat insulating and corrosion coating, is wrapped up on the outside of the heat insulating and corrosion coating
There is polyurethane insulation coating, outside the polyurethane insulation coating there is ripple outer protection tube, there is report in the polyurethane insulation coating
Alert line.
The insulating tube with ripple outer protection tube, the caliber of the service pipe is 15mm-150mm, described
Protective polyurethane layer thickness is 30-200mm, and the ripple outer protection tube thickness is 1-30mm.
The production method of the insulating tube with ripple outer protection tube carries out anti-corrosion first against service pipe inner surface
Spraying by anticorrosive paint after being sufficiently stirred, squeezes into spray gun inner tube, compressed air is pressed into spray gun by pipeline by anticorrosive paint pump
Outer tube is to promote air motor to drive the rotation of anti-corrosion spray atomising head ultrahigh speed with the rotating speed of 35000r/min；Spray gun inner tube and spray
Feeder sleeve in head is connected, and anticorrosive paint injects high-speed rotating anti-corrosion spray atomising head by feeder sleeve, and passes through intensive thereon
Aperture obtain high atomisation, so as in the visibly homogeneous smooth paint film of inner-walls of duct forming layer；Then after treatment
Service pipe outer surface carries out anti-corrosion spray, by the way that outer surface progress chromic acid salt treatment is improved its coating adhesion, finally leads to
It crosses anti-corrosion spray device and carries out anti-corrosion spray；After service pipe is installed stent, corrugated height is penetrated by poling machine
In density polyethylene outer protection tube or plastic cement outer protection tube, alarm system can be added, makes that there is the insulating tube of ripple outer protection tube to possess
Intelligent alarm acts on, and can timely and effectively find the position of simultaneously targeted duct breakage, and pipe ends then are installed foaming gear
Plate seals and leaves exhaust sieve, finally foams by foaming machine spray foam, and end face finishing processing, i.e. shape are carried out after curing
Into final finished.
Beneficial effects of the present invention：
1. the present invention " insulating tube with ripple outer protection tube ", can realize size radian, the continuous turning of big low-angle,
Can be directly realized by bending turn, need not block service pipe turn again connection the problem of.Moreover, heat insulation effect is due to blocking
It is few, so temperature is good, save the energy.
The present invention set " have ripple outer protection tube insulating tube ", the structure of use is protected outside polyethylene outer protective pipe or plastic cement
Pipe has flexibility, and tube wall is in wavy pipeline, can also use the softwares wavy metal pipelines such as aluminium, copper；Polyurethane plastics
Foam heat-insulation layer is using flexible polyurethane；Service pipe road has flexible bendable using materials such as copper, aluminium, plastic cement pipelines
Bent pipeline.
What is used due to outer protection tube and service pipe road is all flexible soft pipeline, so, turn running into low-angle
During curved construction demand, reconnection need not be blocked, turning can be realized in directly bending.
The present invention is provided simultaneously with heat insulating and corrosion coating and improves heat insulating ability and antiseptic property.
Description of the drawings：
Attached drawing 1 is the structure diagram of the present invention.
Attached drawing 2 is schematic cross-section of the present invention.
Specific embodiment：
