Buried steel jacket pipe insulation Features: 1, lower project cost. 2, low heat loss and save energy. 3, corrosion prefabricated buried pipe insulation, good insulation properties, long service life. 4, small footprint, and fast construction, favorable environmental protection. 5, safety. Buried steel jacket insulation spiral pipe laying technology is a waterproof, leakproof laying of new technologies, impermeability, compression and fully enclosed, is a major breakthrough Buried technology used in high water table areas. It is a combination of the transmission medium pipe, steel pipe anti-corrosion coat and superfine wool padding between the pipe and the jacket is made of steel, but also can be graphite, calcium silicon tile shell filled with polyurethane foam and composite. Buried spiral steel jacket pipe insulation structure based on a sliding manner divided into: internal and external sliding sliding. 1. The table below provides the bending properties of the apex diameter bend 180 degrees, reinforced by the curved parts of the surface can not crack. A bending test nominal diameter mm core diameter bend HRB335 6-25 3a28-50 4aHRB400 6-25 4a28-50 5aHRB500 6-25 6a28-502. Reverse bending properties according to the demand side, reinforced can reverse bending performance test. Reverse bending test bending test than the diameter of the apex corresponding increase in a bar diameter. The first positive bent 45 degrees prefabricated buried pipe insulation factory prices, after a reverse bend 23 degrees polyurethane prefabricated buried pipe insulation manufacturers, after the reverse bend 23 degrees. After the reverse bend test, reinforced by the curved parts of the surface can not crack. 4. Surface quality: steel surface bumps are allowed, but must not exceed the height of the transverse ribs, other defects on the steel surface depth and height must not be greater than the site where the size tolerances.
