 Insulation steel pipeline can be anticorrosive coat steel pipeline and filled up in between the steel pipeline and the coat of ultrafine glass woollen composition, can additionally be made from graphite, silicon calcium floor tile covering and also polyurethane foam loaded with steel sleeve steel insulation steel pipeline. It not just has a strong anti-corrosion, waterproof and also impermeability, but additionally has the features of heat as well as high stress resistance. It has a wide applications, can be made use of in the business warm resource, power plant heavy steam transmission, plant vapor pipe, and so on. The cathodic defense of buried shielded steel pipe is a type of electrochemical defense technique in the procedure of metal anticorrosion. The electrode capacity of metal body can be safeguarded from adverse motion by using existing to the safety metal matrix. This is the shift of the steel medium from an atomic state to an ionic state, forming a spontaneous pattern. It basically controls the generation of decay, however the procedure occurs in an electrolyte, so it is extremely appropriate for cathodic defense of straight buried steel tubes. Composition of steel sleeve insulation pipeline: 1. Wldsteel : secure the exterior steel pipe from deterioration, can extend the service life of the steel pipe 2. Outside steel pipe: protect the insulation layer from groundwater erosion, to guarantee the normal operation of the pipeline. 3. Glass wool insulation layer as well as air insulation layer: guarantee that the surface of the external defense tube is maintained typical temperature level. 4. Light weight aluminum aluminum foil reflective layer: reflect part of the warmth of the heat resistant layer to ensure that the natural foam product does not go into the inorganic 5. Not natural hard insulation layer: to make sure the interface temperature with the organic insulation layer, to ensure that the foam is not carbonized. 6. Stainless-steel attaching belt and sliding overview bracket. Make sure that the thermal growth and also cold tightening activity of the functioning steel pipeline is not restricted. 7. Base steel pipeline: it can guarantee the normal flow of the communicating tool. Advantages of insulated steel pipeline. 1 Good thermal insulation efficiency, risk-free as well as trusted, inexpensive, easy building and upkeep, lengthy life span, can move a selection of media. It solves the problems of hot bare pipe end, moving lubrication and also waterproofing at heat of 130 ℃ -600 ℃ in city central home heating. 2. The polyurethane foam insulation layer as well as the external layer of the steel pipeline are closely fitted, which not just separates the air, but additionally separates the infiltration of water. The bubbles are shut and the water absorption rate is small, which plays a great function in anti-corrosion. At the same time, the polyethylene shell and also the glass fiber enhanced plastic shell have excellent anti-corrosion, thermal insulation and mechanical residential or commercial properties. As a result, the external surface area of the base steel pipe will not be corroded by air as well as water vapor, which prolongs the service life of the pipeline. 3 Insulation steel pipeline can not only timely water discharge, but likewise can be utilized as a signal suggestion for daily operation. Pipeline thermal compensation will be performed utilizing premium bellows compensators set up straight into the casing, removing the need for a monitoring well. Additionally, the building is practical, the construction period is brief, appropriate for communicating 2.5 Mpa, steam or other media below 350 ℃. |
