Stainless Steel Sanitary Tube

Stainless steel sanitary tube Specifications

What is a Stainless Steel Sanitary Tube?

This tubing refers to austenitic stainless steel suitable for biotechnology, food and beverages, dairy, and pharmaceuticals. A stainless steel sanitary tube is available in different grades, for example, 304 and 316L. The standard composition is iron with nickel, chromium, manganese, phosphorus, sulfur, silicon, and carbon. But the latter A270 tubing also includes molybdenum for superior corrosion resistance.

What are the benefits of using Stainless Steel Dairy Tubes?

The dairy industry requires strict quality to eliminate bacterial growth that affects human health. A stainless steel dairy tube resists corrosion and is easy to clean and sterilize. It does not react with the lactic acids produced during milk fermentation, thus inhibiting contamination. Stainless steel dairy tubing makes business sense as the equipment stands the test of time.

What is the purpose of stainless steel tri clamp tube?

The primary purpose of stainless steel tri clamp tube is catering to aseptic applications like pharmaceuticals, dairy, and food and beverages. These tubes can be polished or unpolished. But a sanitary tube must display top-notch corrosion resistance and easy maintenance. For example, a stainless dairy tube offers good resistance and limited absorption of chemical cleaners.

We conduct hydrostatic and perforation testing on our stainless dairy tube and ss sanitary tubing to ensure they can withstand extreme conditions and perform well in their intended applications

What are the common testing procedures for a SS dairy tube?

Intensive testing adjudges these tubes appropriate for medical and food/dairy applications. a SS dairy tube undergoes hydraulic testing to assess pressure resistance to the certified rating. It also ensures that the sanitary tubing is free of leakage. Other typical tests include crimping, flaring, and flattening.

What is the lead time for the delivery of Polished Sanitary Tubing?

The typical lead time is 7-20 days. Polished sanitary tubing takes longer to deliver because of the additional time and effort. However, orders can get expedited for urgent requirements. Clients can request a satin finish, mirror polish, etc.

Polishing stainless steel produces a smoother, corrosion-proof surface for dairy tubing. It enhances appearance and quality, simplifying cleaning and repair. SS sanitary tubing usually requires polishing with a finish under 1μm.
