Product name: directly buried steam heat pipe Product synopsis: hebei junfen ma tube Co., LTD. Insists on high technology as the starting point, with professional technology and rich experience in engineering practice, the water level, according to the different region climate Such soil conditions, the development situation of structural types of directly buried steam pipe, and have achieved good economic benefit. Our company possesses mature network design and production of rain, soil liquefaction due to the geographical condition, reduce cost, considering factors such as glass, can be used as part of the sheath, and steel casing, plus the nodes of the reasonable configuration, use effect well room, good economic benefit is obvious. In the coastal cities, high water level, and rich content anionic, steam pipe should be strong resistance, steam and 6.17% tide corrosion resistance. In these areas, we choose the type of steel structure steel sliding, heat preservation material choose those water silicate or owens - cognis centrifugal glass cotton, owens - cognis centrifugal glass cotton by many authoritative institution, good resistance to boil. The choice of Central America plastic production company series corrosion tape. This series of anti-corrosion layer thickness is reached our tape ordinary or strengthening, and reduced the level antiseptic standards for construction of artificial factors influence the quality of anticorrosion, curing time, easy to repair and repairing, ensure the coating quality. According to the requirements of users can choose two (3) layer of epoxy coal tar and PE, etc. Of cathodic protection anti-corrosion Steam pipe stress design is reasonable or not, whether the safe operation of pipeline important factors, my company is willing to years of experience in this field and provide technical support for customers. Adopts scope Products are applicable to transfer temperature in 150 ° c, the pressure between - 600 than 160 Mpa steam. Adopts scope The sliding structure Generally applicable to high water area 1 2 3 inside pipe insulation layer. J strapping 4 5 reflection of steel casing 6 coating Responding to product specifications With owens - cognis centrifugal glass cotton, for example. Take the soil surface temperature ± = 10 degrees Celsius, t thermal conductivity lambda ± = 150 w / (m.k), centrifugal glass cotton thermal conductivity Lambda = 0.052 w / (m.k), medium temperature t = 280 degrees, and the buried depth of the pipe center (from) = 1.5 m (ignoring the adiabatic effect).
