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 Qingdao pvc pipe and drilling directly on top of open bite, and then connected externally threaded plastic parts out. After tests showed that this method of construction can be achieved acceptance pressure test specifications. Also the position of the water in the tube thrust of pvc pipe, 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 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. PVC is very hard, very poor solubility, only a small number of solvent dissolved in cyclohexanone, dichloroethane and tetrahydrofuran and the like, organic and inorganic acids, alkalis, salts are stable, chemical stability with temperature rise reduced. PVC dissolved in acetone - carbon disulfide or acetone - benzene solvents for dry spinning or wet spinning fibers from, say polyvinyl chloride, with flame retardant, acid, anti-microbial, wear-resistant, environmentally friendly features and has good heat retention and elasticity. Hard PVC pipes have nominal diameter of 50CM, but soft PVC pipe is generally the largest of 50mm. pvc pipe fittings rigid PVC pipe specifications: GB / T13020-1991 soft PVC pipe specifications: GB / T13527.1-1992 rigid PVC pipes have nominal diameter units have :( mm) 2.5,3,4,5,6, .. ... 355,400,450,500,560,630,710,800,900,1000 and other PVC-U and the difference between UPVC and UPVC PVC-U is, we usually say that the PVC pipe, but just not the same order in writing . PVC production process, in order to increase the performance of PVC plastics, improve production efficiency Chemical pvc pipe, add a plasticizer (such as DOP, DBP, DINP, etc.), and add the plasticizer in PVC products will be relatively soft. Generally, we will not be added during processing plasticizers PVC products collectively known as UPVC, also writing PVC-U. pvc pipe manufacturer, pvc pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd.
