304 316 316L Food Grade Stainless Steel Pipe for Potable Water

Food grade stainless steel pipe is specific SS pipe for food containers or equipments for food producing. It needs lot of acid and alkali elements during food producing. If the container stainless steel tube is not qualified food grade stainless steel tubing, during the food producing it will generate lot of toxic elements. So It has very strict requirement on lead content which must be much lower than common stainless steel material to meet the requirements of food safety.

Food grade stainless steel pipe refers to conform to the law of the People's Republic of China national standard containers/stainless steel tableware hygiene standards "GB4806.9-2016 stainless steel material, the stainless steel is much lower than normal levels of lead.
Food grade stainless steel pipe refers to food machinery parts that come in direct contact with food, must conform to the requirements of food safety. Because food production process to use a lot of acid and alkali, and stainless steel containing chromium, unqualified stainless steel, will dissolve out of various price chromium which is toxic, And required to limit the variety of metal impurity elements such as lead, cadmium content. All kinds of food storage containers and food processing machinery austenitic stainless steel pipe or iron element size should be chosen. The abrasive tool for machining part also can use martensitic food grade stainless steel pipe.

Food grade stainless steel pipe application: Austenitic stainless steels provide useful resistance to corrosion on a wide range of moderately oxidizing. Some austenitic stainless steel pipes are for general service, for sanitary installations, for water heater, for boilers, for superheaters, for heat exchangers and for compensators service.

key properties for food grade stainless steel pipe: These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
