LESSON 16
EXTERNAL CORROSION
Critical Tasks: 01-5103.30-2123
03-5103.00-0078
OVERVIEW
LESSON DESCRIPTION:
In this lesson, you will learn how corrosion in petroleum and water systems can occur and be controlled. You
will also learn how to conduct support and sustainment operations and set up a maintenance program for
petroleum and water equipment and facilities.
TERMINAL LEARNING OBJECTIVE:
ACTION:
Learn the reason corrosion occurs, learn about the four causes of external corrosion, and
learn about the four corrosion prevention methods.
CONDITIONS:
Given the corresponding references, you will simulate the duties and functions of a
commander/staff officer responsible for setting up a petroleum and water equipment maintenance and inspection
program.
STANDARDS:
Identify and explain the reasons corrosion occurs, its causes, and prevention according to
FM 10-67-1.
REFERENCES:
FM 10-67-1 and MIL-HDBK-200G.
INTRODUCTION
As a petroleum manager, your duties will require supervising and reviewing maintenance operations and PMCS
procedures necessary in maintaining equipment and facilities. Considering the high cost of products and
facilities, it is important that you have an understanding of corrosion and preventive measures that can be
employed to control corrosion.
