Stainless steel food grade tube
Is 304 or 316 stainless steel food grade tube?
Even though, both 304 &316 are food grades, 316 can resist pitting which 304 grade can experience when exposed to salt. The Stainless Steel Food Grade Tubes are deemed safe for food handling, preparation, storage, etc.
SS 304 food grade tubing is quite common and they are widely used because of their affordability. 316 grade is considered ideal for making food grade tubes. They are highly resistant to acids, alkalis and chlorides like salt and will not get corroded by them. The 316 tubes can also be used for continuous services at high temperatures, which is much higher than what is required by the food processing tasks.

What is stainless steel pharma tubes?
The grades 304L and 316L are considered ideal for making Stainless Steel Pharma Tubes. They have become quite popular in the pharmaceutical industry because of their high strength and corrosion resistance properties. The 304L pharmaceutical stainless steel tubes are much more affordable than the 316L stainless steel. However, traditionally the 316L grade is used.
Using the low carbon version of 316 stainless steel pharmaceutical tubes is preferred as it comes with superior mechanical properties. This is crucial because the drugs should always comply with high purity and quality standards. The tubing solution must not cause any type of contamination in the drugs and 316L ss material is known for its sanitation properties.

Why use stainless steel tubes for textile industry?
Using stainless steel tubes for textile industry is quite popular due to the excellent properties it possesses. Apart from excellent resistance to corrosion and high strength, ss also shows good durability. These properties make stainless steel tubes perfect to be used in industries like cloth production. The tubes are used for developing conductive textile, which is used for manufacturing biomedical clothing.
