Insulation steel pipeline can be anticorrosive jacket steel pipe as well as filled up in between the steel pipeline as well as the jacket of ultrafine glass woollen structure, can additionally be made from graphite, silicon calcium floor tile covering and also polyurethane foam filled with steel sleeve steel insulation steel pipe. It not just has a solid anti-corrosion, water-proof and impermeability, but likewise has the qualities of high temperature and also high pressure resistance.
It has a broad applications, can be made use of in the enterprise warm source, power plant vapor transmission, plant heavy steam pipe, and wldsteel so on. The cathodic security of buried insulated steel pipe is a type of electrochemical defense technique in the procedure of metal anticorrosion. The electrode possibility of steel body can be shielded from negative activity by using existing to the safety metal matrix. This is the transition of the metal medium from an atomic state to an ionic state, forming a spontaneous fad. It fundamentally controls the generation of decay, however the procedure occurs in an electrolyte, so it is very ideal for cathodic protection of directly buried steel tubes.
Make-up of steel sleeve insulation pipe:
1. Anticorrosion layer: secure the outside steel pipeline from rust, can lengthen the life span of the steel pipeline
2. Exterior steel pipeline: secure the insulation layer from groundwater disintegration, to guarantee the normal operation of the pipeline.
3. Glass wool insulation layer as well as air insulation layer: make sure that the surface area of the outer security tube is maintained normal temperature.
4. Aluminum aluminum foil reflective layer: reflect part of the heat of the heat resistant layer to make sure that the organic foam material does not enter the inorganic 5.
Not natural tough insulation layer: to guarantee the user interface temperature with the natural insulation layer, to guarantee that the foam is not carbonized.
6. Stainless-steel securing belt and gliding guide brace.
Guarantee that the thermal development and also cool tightening activity of the functioning steel pipe is not limited.
7. Base steel pipe: it can make certain the typical circulation of the sharing medium.
Advantages of insulated steel pipe.
1 Good thermal insulation performance, secure and also trusted, affordable, simple construction and also upkeep, lengthy service life, can transfer a variety of media. It solves the troubles of hot bare pipeline end, gliding lubrication as well as waterproofing at heat of 130 ℃ -600 ℃ in city main heating.
2. The polyurethane foam insulation layer as well as the outer layer of the steel pipeline are very closely fitted, which not only isolates the air, however additionally isolates the infiltration of water. The bubbles are shut and also the water absorption price is little, which plays an excellent function in anti-corrosion. At the same time, the polyethylene covering and also the glass fiber enhanced plastic shell have good anti-corrosion, thermal insulation and also mechanical residential or commercial properties. Consequently, the external surface area of the base steel pipeline will not be rusted by air as well as water vapor, which prolongs the service life of the pipeline.
3 Insulation steel pipe can not just prompt water discharge, but additionally can be made use of as a signal pointer for day-to-day operation. Pipe thermal settlement shall be carried out using top quality bellows compensators installed straight right into the casing, removing the demand for an observation well. Furthermore, the building is hassle-free, the building duration is brief, ideal for communicating 2.5 Mpa, steam or other media below 350 ℃.
