What water pipes are of the best quality?
Plastic composite copper tube, YISHION copper (copper) as pipe fittings, covered with PE plastic, from the comprehensive performance point of view, plastic copper pipe is slightly better than aluminum plastic composite pipe. For example, strength is better, life is longer, and heat resistance is better. But the insulation performance is slightly worse.Pure copper has very high corrosion resistance. After a period of time, a green oxide will appear on the inner surface. But it has no influence on the life of the pipe, the flow rate, and the resistance to the fluid. Aeruginosa is not harmful to human health, and has a certain ability to kill bacteria.The installation methods of plastic compound copper tube are two kinds of clamp type and welding type, and the welding type is more reliable.
Aluminum plastic composite pipe is the earliest water supply pipe replacing cast iron pipe, and its basic composition should be five layers, namely, inside and outside are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.Aluminum plastic composite pipe has better thermal insulation performance, internal and external wall is not easy to corrosion, because the inner wall is smooth, the fluid resistance is very small, and because it can bend freely, so the installation and construction is convenient. As a water supply pipeline, aluminum plastic composite pipe has enough strength, but if the lateral force is too large, it will affect the strength, so it should be built as a pipe or buried in the wall, but it should not be buried in the ground. The connection of aluminum plastic composite pipe is card sleeve type, so it is necessary to check whether the connection is firm through strict pressure test during construction. Two is to prevent frequent vibration, so that the sleeve loose. The three is the length of the installation should be sufficient volume so as not to pull off.
Copper tube, stainless steel tube:In addition to the poor insulation performance of these pipes, other indicators such as strength, life, resistance to the fluid are very good, and should be used as cold water pipeline. Such as hot water transmission, should be added insulation jacket. The connection is mainly made of card sleeve, and the copper tube can be welded as well.Inner lining galvanized iron pipe:That is, in the ordinary galvanized pipe lining a layer of plastic, so that it has corrosion resistance, resistance to small, good insulation performance, but also with galvanized pipe itself high strength characteristics. Most of the pipes are ribbed.
