We all know that plastic pipes are mainly made of polymers, the use of different materials also determines the plastic pipe has several different characteristics. Want to choose the more suitable water pipes, we must first understand the types of plastic pipes are Which.
First, the type of plastic water pipes
Plastic pipes can be divided into upvc (hard PVC), PPR (random copolymer polypropylene), PE-RT (heat-resistant polyethylene) and so on, all of which have their own advantages Shortcomings and the scope of application.
Plastic water pipes can be divided into three types of water supply pipes, drainage sewage pipes and floor heating pipes if they are classified according to purposes, and the water supply pipes are required to meet the requirements of human health for the environment-friendly non-toxic plumbing materials; , Because of the main sewage, but for the length and diameter of the pipe diameter and size requirements are still higher; warm water pipes require water pipes can withstand high temperatures and high pressure, and no deformation and no leakage.
Second, plastic pipe specifications
Plastic water pipes will have different specifications depending on the application. Plastic water pipes are 4m or 6m in length and other sizes are custom made. Compared with the length specifications, plastic pipe diameter and wall thickness specifications are much richer PE-RT Because the tube is mainly used for floor heating pipe, the outer diameter of the wall thickness size and specifications are less; UPVC is mainly used as a drainage pipe, the larger size and select more; and PPR wide range of applications, the pipe wall thickness specifications more More concentrated, and even derived from commonly known as the law, such as D25 * 3.5, diameter 25mm, wall thickness of 3.5mm called 6 points.
Third, the price of plastic pipes
Different materials of plastic pipe raw materials and production processes are not the same, of course, the price will be far cry.
The total cost of plastic pipe not only refers to the price of pipe itself, but also includes fittings, connecting tools, installation costs, pipe loss ratio and installation reliability of the maintenance period and other factors, consumers should be based on the above comprehensive indicators for comparison.
Due to the wide range of plastic pipe specifications, price differences, resulting in many consumers will fall into the wrong selection.
Myth: different materials can be mixed with water pipes
Mentioned above, different materials, plastic pipes have different characteristics and uses.If the UPVC pipe as drinking water pipe, it will be harmful to our health; the UPVC, PPR pipe local heating pipe, water pipe deformation will leak; if the PPR , PE-RT pipe when the sewage pipe, the cost is too high.So, buy plastic pipes, according to the purpose of use to buy.
Mistakes II: different materials pipe fittings
Different materials have different plastic pipe connection. UPVC pipe is used with the diameter of the pipe fittings and PVC glue; PPR pipe connection using hot melt technology, the use of hot melt gun, so that the same material between the pipe in a few seconds The clock is fully integrated into one; PE-RT pipe can be used in addition to hot melt technology, but also according to the diameter of the diameter fused connection or mechanical connection. Therefore, there will be a different connection to the corresponding water pipe fittings, purchase should pay attention to .
Misunderstanding three: plastic pipe can be purchased online
Many people think that connecting the water pipe is a very simple matter, so they will choose to buy water pipes and then to install themselves. In fact, the water pipe connection is also a technical work, you need to install the master years of accumulated experience. How to install the water pipe In addition, the installation of water pipes according to the laying of the specific environment, water pressure to determine the laying of water pipes, pipes should be how to layout, etc., these knowledge are common consumers do not have Suggest that consumers can find a large-scale physical store to buy, so that you can enjoy the high quality after-sales service.
