In the home improvement market, stainless steel water pipes as a new product are often considered by most people to be "luxury", However, after investigation, it is found that the longer the stainless steel water pipes are used, the higher the price advantage is in PPR water pipes.
Take the decoration of an 80 square meter house in 2018 as an example, the decoration of stainless steel water pipes needs about 5000 yuan. Based on the existing new house price of 15000 yuan/square meter and hardcover 1500 yuan/square meter in Chongqing's main city, the cost of water supply pipes only accounts for 0.2-0.4 percent of the house price, and the increased cost due to stainless steel pipes is even more insignificant. In fact, the use of stainless steel water pipes, although the initial investment is high, but its life cycle cost is very low and healthy and environmentally friendly, is not comparable to plastic pipes.
PPR pipe aging and health problems are more prominent, aging plastic is not only easy to explode under the impact of water pressure and water hammer, the service life is greatly reduced. In addition, the inner wall of the water pipe is easy to produce bacteria and the water pipe link is easy to produce harmful substances precipitation, resulting in secondary pollution.
stainless steel water pipe has no plasticizer exudation, is not easy to corrode, does not breed bacteria, long life, healthy and environmentally friendly.
From the perspective of economic use cost, stainless steel water pipes are also more economical than PPR water pipes, so the small editor will give you a specific calculation from the use cost:
Investment cost of water pipe materials = initial cost (including materials, processing and installation) + equipment operating cost (including maintenance, replacement and removal)-recovery cost
This formula lists the measurement index of economic performance of water pipe materials. Among them, the life is the key to the economic performance of the pipe, the longer the life of the water pipe, the lower the cost. Compared with the long life of stainless steel water pipes, the life of PPR water pipes generally needs to be replaced in 10-20 years.
Equipment operating costs include power costs, heat loss, water leakage loss costs, etc. Therefore, long-life maintenance-free and update-free water pipe materials are more economical. Once
stainless steel water pipes are used, they do not need to be replaced for a long period of time, while other pipes cannot reach such a long service life. Stainless steel water pipes can also be recycled by 100 and recycled to make new water pipes. PPR recycling not only generates toxic gases in the recycling process, but also recycles PPR because it contains impurities, so the recycled PPR cannot be used as water pipe materials.
In terms of cost performance, although stainless steel water pipes are expensive on the surface, people who can calculate accounts calculate that the service life of stainless steel water pipes is 100 years, that stainless steel water pipes need no maintenance for life, that stainless steel water pipes bring health and environmental protection to family members, and that stainless steel water pipes can be completely recycled, so stainless steel water pipes are water pipes with super cost performance, it is the best choice for your family's water pipes.
Instead of fantasizing about being the queen of others, it is better to be your own queen. Economic equality between men and women, equality in social status, and equality in labor rights are true equality. Women can also be programmers, drive excavators, and become entrepreneurs and scientists, not caged birds, not synonymous with weakness and emotion.
It is well known that the water of the residents in the whole building enters the branch water pipes of each house through the main pipe and under the action of pressure. However, the water consumption time of each house is not fixed, thus forming a continuous circulation of the water in the main pipe, but the water that has entered the house will not flow back into the main pipe under the action of pressure. At this time, if plastic pipes are still used in our house, when we go out to work and sleep at night, the water left in the plastic pipe is not used for a long time, and the water will remain in the family pipe. During this period, the plasticizer that slowly oozes out will slowly increase with the lengthening of time (the concentration is higher than that of the main pipe). When we turn on the faucet again, we will enter our family "without loss. If we install stainless steel water pipes, then "value-added" plasticizers can be avoided. In addition, the water pipe at the end of the water purifier installed in many people's homes is still PPR. Such installation of the water purifier cannot effectively guarantee the safety of water quality. Finally, the water purifier is also a "decoration.
From the health point of view
Using stainless steel water pipes to prevent secondary pollution of water is to ensure the safety of water quality from the outside, while the optimization of pipeline design and connection mode is to protect the fresh and healthy water quality from the inside. At present, the pipelines of most buildings and households in China are connected in parallel. When a water intake point uses water, only the corresponding pipeline here will supply water. Other pipelines cannot form water flow. Long-term static environment can easily make the water remaining on the inner wall of the pipeline form stagnant water, breeding bacteria and polluting water quality.
