Rigid PVC pipes have nominal diameter of 50CM of pvc pipe prices, 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 pipe has a nominal diameter units have :( mm) 2.5,3,4,5,6, .. ... 355,400,450,500,560,630,710,800,900,1000 such as PVC-U and PVC-U difference UPVC and UPVC is what we usually say that the PVC pipe, but the wording of the order just not the same . PVC production process, in order to increase the performance of PVC plastics pvc pipe, increase productivity, added plasticizer (such as DOP, DBP, DINP, etc.), and add the plasticizer in PVC products will be relatively soft. Generally, we will not add processing plasticizer in PVC products collectively known as UPVC, also writing PVC-U. pvc pipe drying conditions: usually do not require drying. Melting temperature: 185 ~ 205C. Mold temperature: 20 ~ 50C. Injection pressure: can be as large 1500bar holding pressure: can be as large as 1000bar injection speed: To avoid material degradation, the general use of the injection speed considerably. Runners and Gates: All conventional gate can be used. If the processing of smaller components, it is best to use the tip gate or sneak into the gate; for thicker parts, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm. Typical uses: water supply pipes, home pipes, house siding, business machine housings, electronic products packaging green pvc pipe, medical equipment, food packaging. PVC pipe connections are mainly gasket, bonding and flanged three kinds. Greater than or equal to 100 mm diameter pipes commonly used Aprons interfaces; less than 100 mm diameter pipes are commonly used adhesive joints, and some loose-fitting. When crossing sewer pipes or other pipes, metal pipes are normally used, then the plastic pipe and metal pipe flange connection. Before and after the valve is connected to the pipe flange connection are also used. When a small-diameter pipeline by solvent bonding, shall socket at the back of small rounded to form a groove, and to ensure smooth and perpendicular to the axis of the fracture, so as to bond securely to prevent leakage. 2 generally greater than or equal to 100 mm diameter PVC pipes are used Aprons interfaces. Must arrange site before installing the tube socket pvc pipe installation chamfer, also check if the quality apron. You must wipe socket, apron, etc. When installing clean. 3 traditional pipeline trench excavation requires only able to install the pipe into the trench and can be sealed can, in the absence of the original loose soil, compaction can not pressurized cushion.
