SS Tube Applications
Stainless steels are widely used in food and beverage manufacturing and processing industries for manufacture, bulk storage and transportation, preparation and presentation applications. Depending on the grade of stainless steel selected, they are suitable for most classes of food and beverage products. Most containers, pipework and food contact equipment in stainless steels is manufactured from either 304 or 316 type austenitic stainless steels. The 17% chromium ferritic stainless steel (430 type) is also used widely for such applications as splashbacks, housings and equipment enclosures, where corrosion resistance requirements are not so demanding.
In addition to these non-hardenable austenitic and ferritic types higher strength 'duplex' types, such as grades 1.4362 and 1.4462 are useful for 'warm' conditions (i.e. over 50°C) where stress corrosion cracking (SCC) can be a corrosion risk, such as in brewery sparge tanks. Hardenable "martensitic" type stainless steels are widely used for cutting & grinding applications, especially as knives. Effective cleaning is essential in maintaining the integrity of the process and in prevention of corrosion. The choice of cleaning method and the frequency of its application depends on the nature of the process, the food being processed, the deposits formed, hygiene requirements etc.
