Stainless Steel, The Most Suitable Material for Drinking Water Pipes

Galvanized pipes: In the 1980s and 1990s, most old houses used galvanized pipes. Galvanized pipes were used as water pipes. After a few years of use, a lot of rust and scale will be generated in the pipes, polluting the water quality. People who have lived in old houses know that if the faucet is not turned on for one or two days, it will suddenly flow out "yellow water" and "red water". The pipe wall is rusted, the accumulated water is polluted, and the rust causes excessive heavy metal content, which seriously endangers human health. Therefore, in 2000, the state issued a document strictly prohibiting the use of galvanized pipes as tap water delivery pipes!

Aluminum-plastic pipe: Aluminum-plastic pipe is light and easy to construct, but the coefficients of thermal expansion and contraction of metal and plastic in pipe fittings are inconsistent, which can easily lead to misalignment and leakage of the bayonet, peeling of the metal layer and the plastic layer, and a short service life. The pipe is prone to aging, leading to leakage and bursting.

PPR pipe: large thermal expansion coefficient, poor oxidation resistance, not suitable for outdoor installation, easy to be broken by external force. Due to the use of hot-melt welding technology, the high-temperature melting of the pipe interface can easily lead to changes in the chemical composition of the material and precipitation of toxic substances. Various additives and modifiers added in the production process, recycled plastics for reproduction, low production costs, and uneven quality make the material contain biphenol A (environmental hormone), which is called a time bomb for human health. The harm to water quality is long-term and hidden.

Copper pipe: Copper pipes have a certain history of being used as water supply pipes abroad, and have a certain antibacterial effect. It is a good choice to use them as water supply pipes. Many people think that copper water pipes will produce verdigris after long-term use, and heavy metals will exceed the standard. However, verdigris is actually a complex salt formed by sulfur dioxide, carbon dioxide and hydrogen sulfide in the atmosphere and copper oxide on the surface of copper. The content of sulfur dioxide, carbon dioxide and hydrogen sulfide in drinking water in my country's drinking water quality standards is extremely low, and the ionization potential of copper in water is positive, which will not be replaced by hydrogen ions in water, so verdigris is rarely produced on the inner wall of copper water pipes. Although copper pipes are good, the price is extremely high!

Stainless steel water pipes: pipes required for use in green buildings, stainless steel water pipes are environmentally friendly and recyclable, the material is safe and healthy, and no harmful substances will be precipitated after long-term use. The pipe wall is smooth, the water flow is unobstructed, the flow rate is larger, and it is not easy to scale and breed bacteria. It is a special pipe for direct drinking water! Stainless steel material can be implanted in the human body, and there is no possibility of excessive heavy metals. Food-grade 304 or 316 stainless steel water pipes are used, which are suitable for tap water pipes, hot and cold water pipes, and direct drinking water transportation. The water quality is safe and guaranteed!

In addition, stainless steel water pipes have other advantages:

Durability--Stainless steel corrugated pipes can last up to 100 years or more without replacement or repair.

High strength and good ductility--The pipes can withstand the huge pressure of the surrounding soil, heavy trucks on the road, and even "bend first and then fold" when subjected to earthquakes. Because of the high strength, the ends of the pipe fittings can be firmly connected.

Pipe fittings--Stainless steel corrugated pipes can be simply bent to fit the installation, which is simple and fast to install, saving time and money.

Flexibility--Strength and flexibility are combined to protect the pipes even in the event of unexpected mechanical damage (such as being hit by an excavator). Corrosion resistance--Excellent corrosion resistance and anti-aging properties to various water qualities, water treatment chemicals and surrounding soil.

Cleanliness--Stainless steel is basically inert in water, and the release of alloy components is negligible, so the quality of drinking water can be ensured.

Recyclable and reusable--Stainless steel is 100% recyclable and reusable, further reducing the impact on the environment and recovering part of the original cost at the end of its service life.

Therefore, taking all factors into consideration, stainless steel water pipes are the most suitable pipes for transporting tap water and drinking water.
