Insulation steel pipe can be anticorrosive coat steel pipeline and loaded between the steel pipe and also the coat of ultrafine glass woollen structure, can also be made of graphite, silicon calcium ceramic tile covering as well as polyurethane foam filled with steel sleeve steel insulation steel pipe. It not only has a strong anti-corrosion, water resistant as well as impermeability, yet also has the attributes of high temperature as well as high stress resistance.

It has a vast applications, can be made use of in the business warm resource, power plant heavy steam transmission, plant steam pipe, and so on. The cathodic defense of buried protected steel pipe is a kind of electrochemical defense method in the process of steel anticorrosion. The electrode capacity of metal body can be safeguarded from unfavorable movement by applying present to the safety metal matrix. This is the change of the metal tool from an atomic state to an ionic state, developing a spontaneous pattern. It fundamentally regulates the generation of degeneration, however the procedure takes place in an electrolyte, so it is very ideal for cathodic defense of straight hidden steel tubes.

Structure of steel sleeve insulation pipeline:

1. Anticorrosion layer: shield the external steel pipeline from deterioration, can prolong the service life of the steel pipe

2. External steel pipeline: secure the insulation layer from groundwater disintegration, to guarantee the normal operation of the pipeline.

3. Glass wool insulation layer and air insulation layer: guarantee that the surface area of the outer defense tube is maintained typical temperature.

4. Aluminum foil reflective layer: mirror component of the warm of the high temperature immune layer to make certain that the natural foam product does not go into the not natural 5.

Not natural hard insulation layer: to guarantee the interface temperature with the organic insulation layer, to guarantee that the foam is not carbonized.

6. Stainless steel fastening belt and gliding overview brace.

Make sure that the thermal development as well as cool tightening activity of the working steel pipeline is not restricted.

7. Base steel pipe: it can make certain the regular circulation of the sharing medium.

Benefits of shielded steel pipeline.

1 Good thermal insulation performance, secure as well as dependable, low cost, straightforward building as well as maintenance, long service life, can transfer a variety of media. It resolves the troubles of hot bare pipeline end, moving lubrication and waterproofing at heat of 130 ℃ -600 ℃ in city main heating.

2. The polyurethane foam insulation layer and the outer layer of the steel pipeline are very closely fitted, which not just separates the air, however additionally separates the penetration of water. The bubbles are closed as well as the water absorption rate is small, which plays a good role in anti-corrosion. At the exact same time, the polyethylene covering as well as the glass fiber strengthened plastic shell have good anti-corrosion, thermal insulation and mechanical buildings. Therefore, the outer surface area of the base steel pipe will certainly not be worn away by air and also water vapor, which lengthens the service life of the pipe.

3 Insulation steel pipeline can not just prompt water discharge, but likewise can be made use of as a signal suggestion for day-to-day operation. Pipeline thermal settlement will be executed making use of high-quality bellows compensators set up straight into the housing, wldsteel inc. eliminating the demand for an observation well. On top of that, the building is hassle-free, the construction duration is short, ideal for conveying 2.5 Mpa, steam or various other media below 350 ℃.
