Many people will be very curious about the variety of pipes. What kind of pipes are used for general sewage and drainage pipes? EMT pipe bender manufacturers tell users that ordinary PVC plastic drainage pipes are generally enough for sewage and drainage pipes, and PVC plastic pipes are also the most widely used pipes.
PVC plastic pipe is a kind of modern synthetic material pipe. However, the scientific and technological circles have found that phthalein, a chemical additive that can make PVC softer, is harmful to human body. Generally speaking, because its strength is far from being suitable for the pressure requirements of water pipes, it is rarely used in water pipes, because the tap water is directly drunk by human body. Therefore, in most cases, EMT pipe bender manufacturers recommend that PVC pipes are more suitable for wire pipes and sewage pipes.
EMT pipe bender manufacturers tell users that PVC material is one of the largest plastic products in the world. This kind of pipe is not only cheap, but also widely used. PVC resin is white or light yellow powder. Different additives can be added according to different uses. PVC plastics can present different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding proper amount of plasticizer into PVC resin.
