Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! From the early 1980s, the country to promote the use of upvc pipes, and formulated a series of policies, systems, standards, and has accumulated a lot of experience. To today, already has a sound product standards, test method standards and testing methods, technical specifications and other construction projects pvc pipe fittings products, thus unifying the standard size and quality indicators, to achieve the product interchangeability. This shows that the development of pvc water pipe has entered a mature stage, product quality and construction quality are guaranteed, thus ensuring the use of effects pvc water supply pipe. The international standard for water supply pe pipe (ISO4427) until 1996 before the official release. Our ISO4427 reference in 1999 to prepare a national standard GB / T13663, and promulgated pvc pipe fittings in 2000, but so far the standard pe pipe fittings, engineering and other technical specifications continues perfected. This shows that the quality has not been stable domestic pe pipe, pipe fittings supporting not perfect, and therefore can not ensure the production, construction quality. PVC pipe is generally available in the three-way split manifolds or vertical sealing bolt split ends. During the construction, to add a saddle fitting together two half-way, and with the U-bolt clamp, thus thickening of the wall pvc pipe factory, then drilled directly above the open bite Shandong pvc pipe, then external thread pick out the plastic pieces. Tests showed that this method of construction after the pressure test and acceptance can be achieved specifications. Also the water in the tube to produce thrust position, such as elbows, tees and pipe end closure panels and other parts should be set at the pier to withstand the water thrust thrust. PVC pipe as a new type of non-metallic pipes, metal pipes with existing detection equipment can not detect its exact location, but if the construction of the pipeline when the pipeline is buried on top of a buried wire can easily solve this problem.
