Prefabricated buried heating pipe insulation from the inside to the outside structure divided into three layers: the first layer: Working pipe layer depending on the design and customer requirements generally used seamless steel pipe, spiral pipe and straight pipe joints, ppr pipe, stainless steel pipe and other . Steel surface after shot blasting advanced treatment process pipe insulation, pipe rust level up GB8923-1988 standard Sa2 grade, surface roughness up GB6060.5-88 standard R = 12.5 microns. Steel sleeve steel pipe insulation applications: 1, using a sliding bracket, including work on the pipe and jacket pipe wall friction, pipe insulation materials work together to follow the movement of the steel jacket buried steel pipe insulation, does not appear to mechanical wear insulation materials , chalking. 2, high strength steel jacket, good sealing performance buried steam pipe insulation prices, can effectively waterproof, impermeability. 3, the outer jacket pipe with high temperature resin to strengthen the level embalmed so special, the breakdown voltage greater than 3000V, so coat steel pipe coating life of more than 20 years. Prefabricated buried pipe insulation prices, leling pipe insulation, polyurethane insulation provided by Kodak Kodak Building Materials Co., Weifang. Weifang Kodak Building Materials Co.
