Insulation steel pipe can be anticorrosive coat steel pipeline and filled up between the steel pipeline and the jacket of ultrafine glass wool composition, can also be made from graphite, silicon calcium ceramic tile covering as well as polyurethane foam full of steel sleeve steel insulation steel pipeline. It not just has a solid anti-corrosion, water-proof and also impermeability, but also has the qualities of high temperature as well as high pressure resistance.
It has a large applications, can be made use of in the venture warm resource, power plant heavy steam transmission, plant vapor pipeline, and so on. The cathodic defense of hidden shielded steel pipe is a sort of electrochemical defense technique in the process of steel anticorrosion. The electrode possibility of metal body can be protected from adverse movement by applying current to the safety steel matrix. This is the shift of the metal tool from an atomic state to an ionic state, forming a spontaneous pattern. It essentially controls the generation of degeneration, but the procedure occurs in an electrolyte, so it is extremely suitable for cathodic security of straight hidden steel tubes.
Make-up of steel sleeve insulation pipe:
1. Anticorrosion layer: shield the external steel pipeline from deterioration, can lengthen the service life of the steel pipeline
2. Exterior steel pipe: safeguard the insulation layer from groundwater erosion, to make sure the regular operation of the pipe.
3. Glass woollen 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 foil reflective layer: show part of the warmth of the high temperature immune layer to make certain that the natural foam material does not go into the not natural 5.
Not natural tough insulation layer: to make sure the user interface temperature level with the natural insulation layer, to ensure that the foam is not carbonized.
6. www.wldsteel.com attaching belt as well as moving guide brace.
Make certain that the thermal development as well as cold tightening movement of the working steel pipeline is not restricted.
7. Base steel pipeline: it can make certain the regular circulation of the conveying tool.
Benefits of shielded steel pipeline.
1 Good thermal insulation efficiency, risk-free and also reputable, inexpensive, simple building and construction and also maintenance, long service life, can move a range of media. It solves the issues of hot bare pipe end, gliding lubrication as well as waterproofing at high temperature of 130 ℃ -600 ℃ in city central heating.
2. The polyurethane foam insulation layer and also the outer layer of the steel pipe are carefully fitted, which not only separates the air, however likewise isolates the penetration of water. The bubbles are closed and also the water absorption rate is little, which plays an excellent duty in anti-corrosion. At the exact same time, the polyethylene covering and the glass fiber reinforced plastic shell have great anti-corrosion, thermal insulation as well as mechanical buildings. For that reason, the outer surface area of the base steel pipe will certainly not be corroded by air and water vapor, which prolongs the life span of the pipeline.
3 Insulation stainless-steel pipeline can not only timely water discharge, however likewise can be utilized as a signal pointer for day-to-day procedure. Pipe thermal compensation shall be performed using premium bellows compensators mounted straight right into the covering, removing the demand for a monitoring well. In addition, the building is hassle-free, the building and construction duration is brief, appropriate for sharing 2.5 Mpa, steam or various other media below 350 ℃.
