Anonymous users2024-01-31The industry standard of stainless steel drinking water pipe needs to meet the national standard.
GB T12771 "Stainless Steel Welded Steel Pipe for Fluid Transfer".
European standard DIN10312 "Stainless steel pipes and fittings for liquid (including drinking water) transportation".
British Standard BS4127 "Thin-walled Stainless Steel Pipes for Main Water Transportation".
Japanese Standard JISG3448 "Stainless Steel Pipes for General Pipes".
Stainless steel drinking water pipe range standard: DN cattle 150mm, working pressure cattle can transport drinking water, drinking water, hot water and high temperature water with a temperature of 135°C.
If the requirements are high, it must also meet the standard of food grade: food grade stainless steel refers to the stainless steel material that meets the provisions of GB 9684 of the National Standard of the People's Republic of China for Stainless Steel Tableware and Containers.

Anonymous users2024-01-29I don't know what criteria you're asking about, so I've listed a few:
On August 1, 2006, the Ministry of Construction issued the industry standard "Technical Regulations for Pipeline Direct Drinking Water System" (No. CJJ110-2006), which was implemented on the date of promulgation.
On December 15, 2016, the Ministry of Construction of the People's Republic of China issued CJ T151-2016 thin-walled stainless steel pipes in the People's Republic of China Urban Construction Industry Standard.
On May 15, 2017, the Ministry of Housing and Urban-Rural Development issued the industry standard "Technical Regulations for Pipeline Direct Drinking Water Systems in Buildings and Residential Areas" (No. CJJ T110-2017). Special provisions: Stainless steel pipes, copper pipes and other high-quality pipes that meet the requirements of food grade should be selected.
The original industry standard "Technical Regulations for Pipeline Direct Drinking Water System" CJJ110-2006 shall be repealed at the same time.
On March 13, 2019, the Ministry of Housing and Urban-Rural Development issued the national standard "Green Building Evaluation Standard" (GB T50378-2019), which came into effect on August 1, 2019, and the original standard (numbered GBT 50378-2014) was repealed at the same time. The pipes, pipelines, and fittings of the first require stainless steel pipes or copper pipes for the indoor water supply system.
On September 10, 2019, the Ministry of Housing and Urban-Rural Development issued the national standard "Design Standard for Building Water Supply and Drainage" (No. GB50015-2019), which clearly stipulates that stainless steel water pipes are the first choice for indoor water supply pipes.

Anonymous users2024-01-26Legal analysis: Hygienic food-grade stainless steel refers to stainless steel materials that meet the provisions of the National Standard of the People's Republic of China Hygienic Standard for Stainless Steel Tableware and Containers GB 9684-2011, and its lead content is much lower than that of general stainless steel. Food-grade stainless steel refers to the part of the food machinery that comes into contact with food, which must meet certain food safety requirements.
The process of food-grade stainless steel uses a lot of acids and alkalis, and stainless steel contains chromium, and unqualified stainless steel will dissolve chromium at various prices, which is toxic; Moreover, it is required to limit the content of various alloy impurity elements such as lead and cadmium.
Legal basis: "Product Quality Law of the People's Republic of China" Article 2 Those engaged in product production and sales activities within the territory of the People's Republic of China must comply with this Law. "Products" as used in this Law refers to products that have been processed and made for sale.
The provisions of this Law shall not apply to construction projects; However, the provisions of this Law shall apply to the construction materials, building components and equipment used in construction projects that fall within the scope of products provided for in the preceding paragraph.
