=Corrosion and Corrosion Control in the Brewing Industry =

**The Brewery Process **
**// The brewery process is a complicated procedure that includes many different materials. Some aspects of this process are susceptible to corrosion; therefore, it is important to understand the general brewery process before investigating how corrosion occurs within it. //**

The following figure shows a standard micro brewery system unit. An in-depth description of the associated brewery process is provided on another page.



**What Is Corrosion?**
Corrosion is the attack of a metal through a chemical or electrochemical reaction with its environment [2]. In the brewery industry, corrosion affects several aspects of the process. Examples of this include welding of stainless steel pipes, stainless steel reaction vessels, and storage vessels.

The main types of corrosion involved in brewing process are: pitting and crevice corrosion, as well as intergranular corrosion.

**Why Is Corrosion Relevant?**
Corrosion in the brewery is detrimental in several areas: cost, safety, environmental conservation and quality of product are the main concerns. Cost is likely the largest concern for the industry as it can hinder the growth of a company. The relevance of corrosion is discussed further.

There are several different methods used in the brewery industry to prevent corrosion.
