The company has experienced professional and technical personnel, kitchen ventilation pipes, specializing in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. First, it is the 'touch' texture. Generally, coarse particles are likely to blend the impurities. Second, it is to 'see' colors. PP-R pipes are mainly lime green several, consumers tend to believe that white is the best, in fact, color is not judged good or bad quality standards. Third, it is the 'smell' odors. PP-R pipe main material is polypropylene pipes does not smell good, smell the difference there is likely to be blended polyethylene, Hangzhou ventilation pipe production, instead of polypropylene. Fourth, is 'pinched' hardness. PP-R pipe has a considerable hardness, casually can squeeze tube deformation, certainly not the PP-R pipe. Hangzhou Xingda ventilation equipment to undertake all types of tin ventilation engineering, ventilation engineering tin Hangzhou, Shaoxing tin ventilation engineering, Hangzhou fume purification project, Shengzhou ventilation ducts, ventilation engineering, installation and design of Hangzhou, the hotel kitchen fire smoke engineering, Hangzhou, central installation of air conditioning ducts and other train services. The company has experienced professional and technical personnel, specialized in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. Installation of air conditioning refrigeration and air-conditioning supply hot water to the top of the riser pipe vertical and focused on a few pipe shafts, therefore, should be carried out before the construction drawings on paper loft, in order to complete each step of the installation (pipeline corrosion, pipeline Test and pipeline insulation and other processes), Hangzhou ventilation pipe making, but also for future owners to create conditions for maintenance and management. The riser shaft should be installed at the wellhead set up steel supports, upper and lower unity hanging wire installation card holder, install manifold should draw a line position, and prefabricated branch pipes laid in a predetermined position, find the right location with the hook after nailing. Stand pipes should be accounted for and re-design, and at the time of the civil professional formwork, the embedded parts laying ready. Since the air conditioning chilled water riser length is longer, in order to ensure the safe operation of the system, according to design requirements set expansion joints in the pipe shaft and with fixed bracket.
