What Material is Sanitary Tubes?
Stainless Steel, Sanitary tube is usually made of stainless steel and has excellent corrosion resistance, durability and ease of cleaning. Sanitary tube is usually made of different grades of stainless steel depending on the application and industry requirements.
What are the common materials for sanitary tubes?
(1) 304 Stainless steel
304 stainless steel is versatile and offers good corrosion resistance, formability, and weldability. Suitable for a variety of hygienic applications including food and beverage processing.
(2) 316/316L Stainless steel
316/316L stainless steel is an austenitic stainless steel with a higher molybdenum content for enhanced corrosion resistance, especially in chloride-rich environments. Commonly used in industries such as pharmaceuticals, biotechnology and marine applications.
Other stainless steel grades such as 304L and 316Ti are also available depending on the specific requirements of the application.
(3) Copper
Copper tubes, especially copper-nickel alloys, is sometimes used in specific applications where its antimicrobial properties, high thermal conductivity and corrosion resistance are an advantage.
(4) Plastic
Certain types of thermoplastics, such as PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and PTFE (polytetrafluoroethylene), are used for sanitary tube in some non-metallic applications.
These materials are corrosion resistant and suitable for low temperature and non-critical applications.
What factors does the choice of sanitary tube material depend on?
Materials selected should be compatible with the intended application to ensure product purity, prevent contamination and maintain hygienic conditions of the system.
(1) Process fluid
(2) Temperature
(3) Pressure
(4) Cleanliness requirements
(5) Regulatory Compliance
