Beijing steel sleeve steel steam insulation pipe manufacturer, 1. Internal sliding type: the thermal insulation structure is composed of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflection layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion layer. The inner sliding type thermal insulation steel pipe is composed of steel pipe with conveying medium + composite silicate or microporous calcium silicate + rigid polyurethane foam plastic + outer steel pipe + glass steel shell anticorrosion protective layer structure. The heat preservation treatment technology of all kinds of pipe joints is mature and the quality is reliable. There are two categories of prefabricated directly buried insulation pipes!
The main materials of this product are aluminum silicate, microporous calcium silicate, reflective film and polyurethane glass wool, ultra-fine glass wool, rock wool spray, general working steel pipe is seamless steel pipe, coated with glass fiber cloth on the surface of spiral steel pipe and other anti-corrosion treatment. It is an ideal transportation and insulation pipe product for high temperature resistance such as power plant and steam directly buried pipeline. the insulation structure of steel sleeve steel steam insulation pipe can be divided into the following two categories according to different sliding modes.
According to the different sliding modes, the thermal insulation structure of Tongchuan Yaozhou steel sleeve steel composite insulation pipe can be divided into two categories: internal sliding type: the thermal insulation structure is composed of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion layer. The inner sliding type thermal insulation steel pipe is composed of steel pipe with conveying medium + composite silicate or microporous calcium silicate + rigid polyurethane foam plastic + outer steel pipe + glass steel shell anticorrosion protective layer structure.
External sliding type thermal insulation steel pipe structure form 1, inner steel pipe 2, zinc-rich primer 3, sliding guide bracket 4, high temperature resistant glass wool 5, aluminum foil reflection layer 6, air insulation layer 7, jacket steel pipe 8, jacket steel pipe Hengshui rock wool thermal insulation steel pipe manufacturer steel sleeve steel composite thermal insulation steel pipe is one of the underground directly buried pipes, it can also be buried underground without concrete structure. That is, the thermal expansion of the working steel pipe is carried out in the outer pipe, which reduces the material cost, shortens the construction date, and ensures the safety of the heating pipeline, which can be more safely and widely used in different temperature environments. especially suitable for high temperature steam pipeline projects. Construction steelmakers have sharply raised the offer price
And welded with the working steel pipe. The stacking site of steel jacketed steel insulation pipe should be: the ground should be flat and free of hard sundries such as gravel; the ground should have sufficient bearing capacity to ensure that collapse and dumping accidents will not occur after stacking; the stacking site should dig trenches for drainage, and no stagnant water is allowed in the site; the stacking height should not be greater than 2m away from the heat source, and there are fire protection measures; the two ends of the steam insulation pipe should be protected and blocked, and a canopy should be used when storing in the open air. Attention should be paid when loading and unloading steel sleeve steel insulation pipe: hook the earring or tie the outer casing with a sling whose width is greater than 50mm. It is strictly forbidden to load and unload with wire rope directly on the external anti-corrosion layer, thus damaging the anti-corrosion layer.
