Description
Technical field
The utility model is related to a kind of conveyance conduits, and the stainless steel double connected is done with stainless steel short tube more particularly, to a kind of
Close utilidor.
Background technology
In the production and life of the mankind, through the conveyance conduit frequently with steel pipe as hot water.The advantages of steel pipe is anti-
Pressure energy power is strong, but its corrosion resistance is poor, then just takes anti-corrosion measure (such as steel pipe stainless steel layer and painting in steel tube surface
Epoxy resin etc.), but all there are the following problems for all anti-corrosion pipelines：
Operation difficulty of (1) two stainless steel composite pipe when construction is welded to connect is very big.
(2) two stainless steel composite pipes are during being welded to connect, because pipeline easily occurs during production and transportation
It deforms and misalignment occurs and lead to stainless steel layer failure welding.
In this way, have led to using higher cost anti-corrosion composite steel tube interface and do not do any corrosion-resistant, cost compared with
The corrosion resistance of low clean steel pipe is essentially identical.
Invention content
The utility model aiming at technical problem present in background technology, provide it is a kind of it is corrosion-resistant, low energy consumption and the longevity
Life length makes the stainless steel composite thermal pipeline connected of stainless steel short tube.
For this purpose, the utility model its be equipped with steel pipe, the both ends of steel pipe are equipped with stainless steel short tube；Steel pipe inner wall is equipped with interior anti-
Rotten layer, outer wall of steel pipe are equipped with external anti-corrosion layer, and insulating layer is equipped on the outside of external anti-corrosion layer, protective layer is equipped on the outside of insulating layer.
Preferably, interior erosion resistant coating is stainless steel layer.
Preferably, external anti-corrosion layer is stainless steel layer.
Preferably, external anti-corrosion layer is anti-corrosive organic coatings layer.
Preferably, the stainless steel layer of inside and outside erosion resistant coating is stainless steel plate and carbon steel sheet hot rolling composite joint.
Preferably, anti-corrosive organic coatings layer is connect with pipe coating.
Preferably, insulating layer is polyurethane foamed material.
Preferably, protective layer is glass reinforced plastic pipe or polyethylene sheath.
The utility model is simple in structure, can be applicable in 70 °~150 ° high-temperature-hot-waters (steam and hot water) of conveying and use, be applicable in model
It encloses relatively wide；The setting of inside and outside stainless steel layer is strong bonded with steel pipe inside and outside wall, effectively prevent wall erosion inside and outside steel pipe, extends the longevity
Life, antiseptic property are good；Insulating layer (polyurethane foam) uses floride-free technology, pollution-free to air, meets environmental requirement.Pressure resistance
Degree is high, 60~80kg/m of capacity3, compression strength is more than 0.6MPa；Protective layer uses fiberglass or polyethylene sheath anti-corrosive properties
Can be good, moisture resistant is ageing-resistant.The setting of stainless steel layer reduces the friction coefficient of fluids within pipes flowing in steel pipe, reduces resistance
Power can greatly reduce cost of investment, greatly reduce energy consumption in pipeline operational process and save operating cost.Stainless steel is short
Pipe does the problem of design connected avoids steel pipe erosion resistant coating is easily destroyed in the welding process.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Symbol description in figure：
1. steel pipe；2. stainless steel short tube；Erosion resistant coating in 3.；4. external anti-corrosion layer；5. insulating layer；6. protective layer.
Specific implementation mode
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1, the utility model is equipped with the steel pipe 1 for conveying heating power fluid, the inner wall of steel pipe 1 is interior erosion resistant coating
3, interior erosion resistant coating 3 is pricked using carbon steel sheet with Stainless Steel plate heat, and thickness is 0.5~5mm, can be stainless steel layer；Steel
The outer wall of pipe 1 is equipped with external anti-corrosion layer 4, and thickness >=0.3mm of external anti-corrosion layer 4 can be stainless steel layer, or You Jifang
Rotten dope layer；When for stainless steel layer, carbon steel sheet is used to be pricked with stainless steel plate heat；When for anti-corrosive organic coatings layer,
It uses spray gun or complete special equipment to spray to be formed.External anti-corrosion layer 4 is strong bonded with steel pipe 1, when external protection is in construction
When damaged or other reasons damage, external anti-corrosion layer 4 can prevent the media such as water from contacting with 1 outer surface of steel pipe to cause to corrode.
The periphery of external anti-corrosion layer 4 is equipped with insulating layer 5, and insulating layer 5 is the polyurethane foam of 150 DEG C of heatproof, adds floride-free catalysis
Agent and various small powders, it is 60~80kg/m to form unit weight3Rigid foam, compression strength is more than 0.6MPa, and water absorption rate is low, density
Greatly, intensity is high, heat insulation effect is good, and the thickness of insulating layer is 40mm or more.
The periphery of insulating layer 5 is equipped with protective layer 6, and protective layer 6 can be glass reinforced plastic pipe or polyethylene sheath, can also be
It is entwined by epoxy resin and fiber, as long as preferable protective action can be played；Protective layer 6 has preferable moisture resistance
It can be good with resistance to chemical corrosion, ageing-resistant performance.The thickness of protective layer 6 is 5~10mm.
The both ends of steel pipe 1 are equipped with stainless steel short tube 2, and the length of stainless steel short tube 2 is 20~200mm.It is being connected two
When pipeline is welded, the design of stainless steel short tube 2 avoids the technology that two pipeline anticorrosion coatings are more easily damaged well and asks
Topic, to save welding after need repaired mouth the step of, welding efficiency greatly improves.The inner surface of stainless steel short tube 2 is prevented with interior
The inner surface of rotten layer 3 flushes, and reduces the flow resistance of fluid, more efficient.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
