Advantages and disadvantages of stainless steel water pipes? Which is better, stainless steel water pipe or ppr water pipe

Advantages and disadvantages of stainless steel pipes

1, health and health

Stainless steel is a healthy material that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. The soaking water test shows that all the indexes meet the requirements of relevant national drinking water standards. The inner wall of stainless steel pipeline is smooth, and it will not deposit scale after long-term use, and it is not easy to be contaminated by bacteria, so there is no need to worry about the water quality being affected, and it can prevent the secondary pollution of water.

2. Pay attention to material selection

All raw materials are made of 304, 304L, 3 16 and 3 16L brands, all of which meet the requirements of JIS4305. The above brands have the characteristics of stable performance, high strength and low thermal expansion coefficient.

3. Durable

The thin and dense chromium-rich oxide film on the surface of stainless steel makes stainless steel water pipes have good corrosion resistance in all water quality, including soft water, even if they are used underground. The field corrosion test data show that the service life of stainless steel water pipes can reach 100 years, and maintenance is almost unnecessary during the service life, which avoids the cost and trouble of replacing the pipes and has low comprehensive use cost.

4. High temperature and high pressure resistance

Stainless steel can work safely for a long time at the temperature of -270℃-400℃. No matter at high temperature or low temperature, harmful substances will not precipitate, and the properties of the material are quite stable. The tensile strength of stainless steel water pipe is more than 530 N/mm, and it has good ductility and toughness. The high strength of stainless steel water pipes greatly reduces the possibility of water leakage under the influence of external forces, significantly reduces the water leakage rate, and effectively protects and utilizes water resources.

5. Energy conservation and environmental protection

The inner wall of stainless steel pipeline is smooth and the water resistance is very small, which reduces the pressure loss and transportation cost. Due to the low thermal expansion coefficient of stainless steel, the heat energy loss in hot water pipeline is effectively reduced. Stainless steel material is 100% renewable material and will not cause public hazards to the environment.

6. Wide application range

Stainless steel pipes can be widely used in cold water, hot water, drinking water purification, air, gas, medical gas, petroleum, chemical industry, water treatment and other pipeline systems.

7. Economical and practical

Since the invention of stainless steel in the 20th century, stainless steel has become a common material. Among all kinds of water pipes, stainless steel water pipes are the best. This is related to the excellent properties of stainless steel, such as corrosion resistance, high strength and strong impact resistance. Its service life can be said to be the same as that of a building. Investing once and benefiting for life can be described as "once and for all".

2. Which is better, stainless steel water pipe or ppr water pipe?

1 durability

Stainless steel water pipes: Stainless steel water pipes have been used for more than 70 years, which have the same life as buildings and do not need maintenance in the later period.

PPR water pipe: The service life of PPR water pipe is 15-20 years, and the maintenance and replacement costs are high.

2, pipeline strength

Stainless steel water pipe: the material strength of stainless steel water pipe is high, and it can withstand the instantaneous pressure of 89 MPa. Stainless steel will not rust or age.

PPR water pipe: The strength of PPR water pipe material is less than one tenth of that of stainless steel, and it will break when it is hit.

3. Carrying capacity

Stainless steel water pipe: stainless steel water pipe has high pressure bearing capacity and can resist 2.5Mpa pressure. Metal pipe is the first choice for high-rise water supply.

PPR water pipe: PPR water pipe has low pressure bearing capacity, which is especially unsuitable for high-rise water supply.

4, pipeline quality

Stainless steel water pipe: stainless steel water pipe has small thermal expansion coefficient and will not be deformed.

PPR water pipe: PPR water pipe has a large thermal expansion coefficient and is severely deformed and bent after being used for a period of time.

5. Environmental protection and health

Stainless steel water pipes: Stainless steel water pipes are green, environmentally friendly and healthy, and will not precipitate harmful substances and cause secondary pollution to water sources.

PPR water pipes: Red water, smelly water, environmental hormones and plasticizers have always been the problems of plastic pipes.

6. Water impact

Stainless steel water pipe: the inner wall of stainless steel water pipe is smooth, which is not easy to accumulate scale and does not affect the water flow.

PPR water pipe: The inner wall of PPR water pipe is rough and easy to scale. After years of use, the water flow decreases.

7, material aging

Stainless steel water pipe: 304 food-grade stainless steel does not rust or age.

PPR water pipes: PPR water pipes are prone to aging, hardening, embrittlement and bursting.

8, water leakage hidden trouble

Stainless steel water pipe: the hidden danger of water leakage of stainless steel water pipe is small, and the thread bonding technology can ensure that the pipe will never leak.

PPR water pipe: PPR water pipe is easy to leak due to low pressure, thermal expansion and deformation, aging and brittleness.

9. Installation convenience

Stainless steel water pipe: the installation of stainless steel water pipe is simple, and the molding takes 15 seconds. Workers do not need to be electrified on site to operate, which is easier and safer.

PPR water pipe: The hot-melt connection of PPR water pipe needs electricity, and workers need to master some experience in temperature and time.

10 grade

Stainless steel water pipes: Stainless steel water pipes are more beautiful and higher in grade, which improves the grade of the whole building and is conducive to the sales of buildings.

PPR's water pipes: PPR's water pipes and plastic pipes are too common and of low quality to be a selling point of real estate sales.
