Stainless steel water pipes are so popular in the international market, why?

As early as more than a decade ago, some developed countries such as the United States, Europe, and Japan have abandoned traditional pipes such as galvanized steel pipes, plastic pipes, and copper pipes and turned to stainless steel water pipes. The use of stainless steel water pipes is becoming a global development application.
Now stainless steel has become the best hydropower installation material on the world home decoration market. In 1980, Japan formulated industrial standards (JIS g 3448-stainless steel pipes for general piping), and in 1982, the Japan Water Works Association formulated jwwa g 115-stainless steel water pipes for water supply and jwwa g 116-stainless steel water pipe joints for tap water, and subsequently formulated Stainless steel bellows standard. In 1999, the Tokyo Water Affairs Bureau used 316 stainless steel bellows as the standard material, marking the construction of stainless steel water pipes and water pipes into the standardized track. Now in Tokyo, Japan, the penetration rate of stainless steel water supply pipes has reached almost 100%. All residential areas are all equipped with stainless steel water pipe pipes. Friends who have been to Japan should see that there is ready-to-drink tap water on the streets, all of which are made of stainless steel. Water pipe, this kind of ready-to-drink water tastes sweet, this stainless steel water pipe greatly improves the water quality, and can also enhance the earthquake resistance.
In the United States, stainless steel has been successfully used in more than 100 drinking water treatment plants and transmission systems. In 2003, the latest edition of the “Water and Housing Standards” of the American International Standards Committee once again included this aspect, indicating that the use of stainless steel water pipes has been officially approved by the United States. Other countries, such as Health Canada, the World Health Organization, and the Dutch Health Certification Board have also confirmed this standard. Ford Stadium is a new $300 million stadium in Detroit. Its main water supply system includes direct drinking water pipes at each point of sale, all made of 304 stainless steel. Stainless steel water pipes have been widely used in beauty.

Germany used a lot of stainless steel materials in the water system in 1980 to save water resources. The German Mapress company produces 40.6 million pipe fittings annually, becoming the largest pipe fitting manufacturer in Europe. 2001 sales data show that: stainless steel sales accounted for 65% of sales, carbon steel pipe sales accounted for 34% of sales. Since 1995, stainless steel pipes have been widely used in various cities. Experience has shown that stainless steel pipes are corrosion-resistant and high-strength and can withstand ground subsidence and earthquakes. Its service life is at least 70-100 years, which is more economical and safer than plastic pipes.
The British used to use copper pipes. Later, due to the corrosion of the copper pipe by the water quality, the water pipe was easy to leak. Later, all cold and hot water pipes were replaced with stainless steel pipes. After more than 10 years of use, the hot and cold water pipes were disassembled to study the use of stainless steel pipes and joints. The results show that the stainless steel pipes and joints are in good condition with no signs of corrosion.
Southeast Asia is one of the regions with the rapid development of stainless steel pipes. The proportion of cold water, hot water, and direct drinking water pipes in Malaysia, the Philippines, South Korea, Singapore, Thailand, and Taiwan has increased significantly.
In Malaysia, since 1997, the Water Authority has collaborated with the water industry to draft a standard specification for the use of stainless steel welded pipes and stainless steel fittings in water supply systems. In April 2001, the Malaysian Water Authority officially issued a standard stipulating that before and after the water meter is connected to the main public water pipeline, only austenitic stainless steel welded pipes can be used for the water supply pipeline.
In Singapore, the Water Authority is preparing to replace the water supply pipes under its jurisdiction with stainless steel pipes, with a view to providing sustainable water resources for Singapore in the 21st century, improving water quality, improving system operation reliability, and greatly reducing operating costs. At the same time, thousands of tons of stainless steel pipes will be used for large-scale replacement and reconstruction of existing sewage treatment systems. The 20-year project will cost S$7 billion and bring billions of dollars in economic benefits.
