PVC pipe is generally available in the three-way split manifold stop cock or vertical split. In construction, to add a saddle fitting two combined half-way, and with the U-bolt clamp, thus thickening the wall, then drill directly above the open bite, and then pick out externally threaded plastic parts. After tests showed that this method of construction can be achieved acceptance pressure test specifications. Also in the flow tube produce thrust position, such as elbows, tees and pipe end closure panels and other parts should be set at the pier to withstand water thrust thrust. PVC pipe as a new non-metallic tube chemical pvc pipes, metal pipes with existing detection equipment can not detect its exact location, but if the pipe laying construction of the pipeline buried on top of a wire can easily solve this problem. 1. PVC Profile profiles, PVC profile is the area of ??greatest consumption in China, accounting for about 25% PVC of total consumption, the main material for the production of energy-efficient doors and windows, the application amount in the country is still relatively substantial growth. In developed countries, the market share of plastic doors and windows is on top, such as Germany 50%, France 56%, US 45%. 2. PVC pipes in many PVC products, PVC pipe is the second largest consumption Qingdao pvc pipe, about 20% of its consumption. In China, compared with PE pipe and PVC pipe PP tube develop early varieties, excellent performance, using a wide range on the market occupies an important position. 3. PVC film PVC film in the field of PVC consumption ranked third, accounting for about 10%. PVC mixed with the additives, after plasticizing, using a three-roll or four-roll calender mechanism into a transparent or colored film of a predetermined thickness, a film processed in this way, the film has become pressing. You can also cut, heat processing, packaging bags, raincoats, tablecloths, curtains, inflatable toys. Wide transparent film can be used for greenhouse, plastic greenhouse and mulch purposes. After biaxially stretched film, suffered heat shrinkage characteristics, can be used for shrink packaging. 1914 found that the organic peroxide can accelerate the polymerization of vinyl chloride pvc pipe, 1931 German law the company uses to achieve industrial production of polyvinyl chloride emulsion polymerization. 1933 WL Simon proposed using a high-boiling solvent and tricresyl heated and mixed with PVC, can be processed into a soft PVC products, this makes practical use of PVC has been a real breakthrough. British Imperial Chemical Industries Company, Union Carbide and Goodrich Chemical Company almost simultaneously developed the suspension polymerization of vinyl chloride and PVC processing application in 1936. In order to simplify the production process, reduce energy consumption, the 1956 French Shengge Bang has developed a bulk polymerization. 1983 pvc pipe, the world's total consumption of about 11.1Mt, the total production capacity of approximately 17.6Mt; polyethylene production is second only to the second largest plastic varieties, accounting for 15% of the total output of plastic. PVC production plant in China in 1956 to design pilot production in Liaoning Jinxi Chemical Plant, 1958 3kt means the official industrial production, 1984 annual 530.9kt.
