On August 1, 2019 this year, the Ministry of housing and urban rural development of the people's Republic of China formally began to implement the national standard, that is, the "green building evaluation standard" clearly requires that the indoor water supply system should use copper or stainless steel pipes, because of its unique advantages, safety, health, environmental protection, health, corrosion resistance, compressive strength and other characteristics, so that the stainless steel pipes are gradually understood and popularized by many people, but actually two years earlier China has already begun to attach great importance to the requirements of water supply pipes and issued relevant policies, but they have not been vigorously promoted. Next, Xiaoyuan will tell you why stainless steel pipes are a trend. Relevant documents issued by governments in many places stainless steel pipes are selected as the preferred materials for water supply pipes

2006 Ministry of construction

On August 1, 2006, the Ministry of housing and urban rural development of the people's Republic of China issued the national standard technical specification for direct drinking water system (No. cjj110-2006), which will be implemented as of the date of promulgation. As the first technical regulation for direct drinking water in China, its implementation will have a key impact on regulating and guiding the design, construction and installation, operation, maintenance and management of direct drinking water system, as well as the drinking water safety of residents. At the same time, it also provides a standard basis for the direct drinking water industry market and a reference standard for the industry market norms.

2013 Shenzhen

As early as May 21, 2013, the general office of Shenzhen Municipal People's government has issued the notice on the implementation plan of Shenzhen high quality water access project, which clearly indicates that 304 stainless steel pipe is mainly used in this transformation, which can improve the quality of drinking water and reduce the leakage rate.

2017 Ministry of housing and construction

On May 15, 2017, the Ministry of housing and urban rural development of China issued the industry standard technical specification for direct drinking water system of building and community pipeline (No. CJJ / t110-2017), which was implemented from November 1, 2017. Special provisions: stainless steel pipes, copper pipes and other high-quality pipes that meet the requirements of food grade shall be selected. The original industry standard technical specification for direct drinking water system cjj110-2006 shall be repealed at the same time.

2018 - Shawan District, Leshan City

In July 2018, Shawan District of Leshan City was officially promoted, and 304 thin-walled stainless steel water pipes were fully implemented in the newly-built residential quarters, which were regarded as necessary conditions for acceptance of water supply supporting facilities. This is also the second county-level city in China to implement stainless steel water pipes for new houses.

2018 Ministry of housing and construction

On July 10, 2018, the Ministry of housing and urban rural development of China issued the national standard technical standard for the application of solar water heating system in civil buildings (No. gb50364-2018), which will be implemented from December 1, 2018. Among them, article 5.5.4 clearly stipulates that "stainless steel pipes, copper pipes and other metal pipes to ensure water quality shall be used for pipes and fittings directly supplying domestic hot water".

Changsha Municipal Commission of housing and urban rural development issued the notice of "technical guidelines for one household and one table of building water supply and secondary water supply in Changsha". The notice clearly puts forward the selection standard of pipes and fittings. PP-R, PE, PEX, UPVC and other water supply plastic pipes shall not be used in high-rise buildings. The stainless steel pipes and fittings are the first choice.

2018 Fujian people's Government

On September 20, 2018, the people's Government of Fujian Province issued a notice requiring the use of stainless steel as drinking water pipes throughout the province.

2019 Henan Province

On June 17, 2019, the Henan government officially released the introduction of food grade stainless steel pipes into Zhengzhou water quality secondary water supply system, vigorously promoting the use of high-quality stainless steel pipes.

On March 13, 2019, the Ministry of housing and urban rural development of China issued the national standard "green building evaluation standard" (No.: GB / t50378-2019), which will be implemented from August 1, 2019. The pipes, pipelines and pipe fittings in 4.2.7 require the indoor water supply system to adopt copper or stainless steel pipes. The original green building evaluation standard (GB / t50378-2014) shall be repealed at the same time.

Stainless steel pipe

With the release of the relevant policies of "Application of stainless steel pipe" in 2017 and 2018 and the announcement of the gradual specification of stainless steel pipe industry, the production technology and connection technology of stainless steel pipe will also accelerate to standardization and become more and more perfect. For example, Chongqing Juyuan stainless steel water pipe has the characteristics of corrosion resistance, strong pressure resistance, and elimination of secondary pollution of water. Its connection mode of double ring pressure connection and snap ring bonding is a national patent product. I believe in the future stainless steel pipe industry, will be better and better!
