Four Types of Heat Exchanger Failures
|
|
U-tube heat exchangers usually provide a long service life with little or no maintenance because they do not contain any moving parts.
However, there are four types of heat exchanger failures that can occur, and can usually be prevented: mechanical, chemically
induced corrosion, combination of mechanical and chemically induced corrosion, and scale, mud, and algae fouling.
This article provides plant engineers with a detailed look at the problems that can develop.
It also describes the corrective actions that should be taken to prevent them.

Steam Pressure and Product Selection for Heat Transfer Systems
|
|
Choosing the operating pressure for a heat exchanger system is an important design decision. The choice of pressure will
impact the selection of the heat exchanger and the steam trap for your application. In many cases, adequate performance can be
obtained over a wide range of system pressures. However, failure to consider all of the system characteristics and components can
lead to inefficient operation.
