The difference between cold water pipes and hot water pipes is still very big. The prices of different wall thicknesses are different. The hot water pipe is thicker than the wall of the cold water pipe. The price is relatively expensive when the cold water and hot water pipes work; the red line Identify the blue lines marked on the hot water pipes and cold water pipes, and have a logo that also bears the pressure. In addition, if the wall thickness of the same specifications can also distinguish between cold and hot water; the cold water pipes are generally lower than the freezing point. Icy natural thaw. Can't beat or bake. The following small series introduces the difference between cold water pipes and hot water pipes. The difference between cold water pipes and hot water pipes 1, the difference between materials Although the hot water pipe and the cold water pipe are both used for the water pipe in the house, because the environment and the temperature of the two are different by day, the production materials of the two pipes are different. The production materials used to manufacture hot water pipes must be copolymerized PP-R, while the production materials used to manufacture cold water pipes are mostly homopolymer PP-B. 2, the difference between the use of the environment The hot water pipe made of PP-R material has better stability and mechanical properties under high temperature conditions, but it will be brittle under low temperature conditions and have a high probability of being damaged. The cold water pipe made of PP-B material has good toughness under low temperature conditions, but if the load has a low heat distortion temperature, if it is used under high temperature conditions, it will easily deform and its strength will be greatly reduced. 3, the difference in stress intensity Because the hot water pipes and cold water pipes are different, their strength is also different. The hot water pipe can be cracked with a hoe, but the cold water pipe may only become white due to the force, and it may not be cracked. Of course, this does not include that some merchants mix many limestone powders during production in order to reduce the cost, resulting in a decrease in the strength of the water pipe. In this way, even cold water pipes can be cracked with a hoe. 4, the difference in performance When the hot water pipe and the cold water pipe are of the same specifications, and the wall thickness is the same, then how to distinguish the hot water pipe and the cold water pipe? Generally, the cold water pipe has the memory water below the freezing point, and can be naturally thawed under the cold condition. But can't beat or bake. Therefore, in order to avoid the cracking and cracking of the water pipes, under normal circumstances, the exposure of the water pipes should be avoided as much as possible so as not to affect the service life of the water pipes. And in the design process, it is also necessary to maximize the performance of the pipeline. 5, the difference in price Because the hot water pipes and cold water pipes have different pressure requirements when they are used, the wall thicknesses of the two water pipes are also different. Also, because the wall thicknesses of the two water pipes are different, the price is different. Hot water pipes are thicker than cold water pipes, so prices are higher. PPR pipe good or bad 1, touch Whether the texture is delicate and the particles are even. At present, PPR tubes on the market are mainly white, gray and green. Under normal circumstances, recycled plastic cannot be white, so consumers often think that white is the best. In fact, this view is more one-sided. As technology has improved, color is not a criterion for discriminating PPR tubes. The quality of the pipe can't solve the problem. If it is touched, the rough particles are likely to be mixed with other impurities. 2, smell There is no smell. The main material of the PPR tube is polypropylene. Good tubes have no odor, and bad ones have strange smells. They are very willing to blend polyethylene instead of polypropylene. 3, pinch The PPR pipe has a considerable hardness, and it can be shaped into a deformable pipe, which is certainly not a PPR pipe. 4, ç ¸ Good PPR pipe, "Resilience" is good, too easy to shatter natural PPR pipe is not good. However, the hardness is not equal to the elasticity, and consumers should leave doubts about PPR tubes that are not broken. Because some unscrupulous manufacturers increase the hardness of pipes by adding too many impurities such as calcium carbonate, such pipes are prone to embrittlement for a long time. 5, burning Igniting a fire, it is intuitive and very useful. PPR pipes that contain recycled plastics and other impurities in their raw materials will emit black smoke and have a pungent odor; good materials will not only emit black smoke and odor after burning, but the burnt-out liquid will remain clean after burning.
