UPVC pipe is a plastic pipe made of polyvinyl chloride (PVC) resin without plasticizer. With the development of chemical industry technology, it is now possible to produce non-toxic grade pipes, so it has the properties of general polyvinyl chloride and has added some excellent properties. Specifically, it has the advantages of good corrosion resistance and flexibility, so Especially suitable for water supply pipe network. Because it is not conductive, it is not easy to electrochemically react with acids, alkalis and salts. Acids, alkalis and salts are difficult to corrode it, so no external anticorrosive coating and lining are needed. And the flexibility is good, which overcomes the shortcomings of the brittleness of plastic pipes in the past, and can yield under load without cracking. In addition, UPVC pipes are also light in weight. The advantage of convenient transportation. The proportion of UPVC pipe is about 1.4 (the proportion of cast iron pipe is about 7.4), which is one-fifth of the weight of cast iron pipe. UPVC pipe can save transportation cost 1/10-1/5 compared with cast iron pipe. Its transportation, loading and unloading construction are very convenient. The construction environment of water supply pipelines is often difficult and the construction site is muddy. It would be the most ideal thing to reduce the labor intensity of workers and shorten the construction period. The UPVC pipe can realize this ideal. UPVC pipes are light in weight and can be moved manually during installation, generally without machinery. For example, a DN200 UPVC pipe with a length of 6m has a dead weight of about 55Kg, while a cast iron pipe with the same diameter and length has a dead weight of 304Kg. The UPVC pipe can be carried by one person during installation, while the cast iron pipe requires three persons or machinery to drop the pipe, which greatly reduces This improves the labor intensity of workers and saves working hours and construction costs. UPVC pipe connection methods include socket rubber ring connection, adhesive connection and flange connection. These connection types can be installed directly in the pipe trench without digging another work pit, and there is no need to use oil hemp or expanded cement to make the connection. You can use a manual hoist or hand to put the rubber ring on the pipe socket end and insert it directly into the bearing. In the mouth, the depth of insertion can be determined by the mark on the end of the tube.
