ASTM A270 TP304 Sanitary Stainless Steel Welded Tubes For Oil Gas Chemical
overview
For sanitary applications requiring a cost effective alloy, stainless steel grade 304 is one of the best sought after. Usually cold worked, ASTM A270 TP304 sanitary stainless steel tubing is used primarily as a structural component. Typically, industries like the food and beverage, medical, pharmaceutical, and biological industries use ASTM A270 TP304 sanitary stainless steel tubing. Since these materials are required to be sanitary and non-reactive, the metal is chosen accordingly.
While Grade 316 is a very popular choice, the use of UNS S30400 stainless steel sanitary tubing is noted in some plants for two reasons. First, the cost of using this material is very low. Second, astm a270 tp304 alloy is available globally, so it is easy to source this tubing. In general, the material used to produce these tubes needs to be kept sterile at all times. Therefore, astm a270 304 sanitary SS tubing is typically sterilized using heat and alkaline cleaners, neither of which will react to the material. Sterilization of these A270 TP304 sanitary tubes can be performed from several times per week to several times per day, depending on the industry.
In order to maintain the sterility of the equipment, the surfaces of these ASTM A270 TP304 tubing components are typically finished or machined for a smoother surface. the smooth surfaces of the interior and exterior of the ASME SA270 TP304 tubing contribute to a better transition of the product. In addition, the smoother surface ensures a clean surface as there is no residue on the walls of ASTM A270 TP304 tubing.
