Process Piping and Heat: Solutions to Consider

There are several different processes that require a product to flow through a pipe from one piece of equipment to another. A certain level of heat is often required for this process piping, and this heat must be at very high levels for many applications.

Filtration Strategy

Proper filtration is essential to process flow operation. Improper filtration or lack of filtration can wreak havoc on components, reducing their life and changing the final product. If left unaddressed, this can lead to equipment failure, process upsets, increased quality issues and in some cases, unplanned shutdown. Thus, making an investment in the correct filter for the process is a wise choice.

Varnish is a common problem for a wide range of hydraulic fluids and lubricants, especially in turbine and plastic injection molding applications. It results in valve sticking, shorter fluid life, shorter filter life and unscheduled downtime.

Achieving effective catalyst regeneration requires a process that produces a very high level of heat in a very efficient manner. Over the years, there have been several different approaches to create this required heat. Traditional steam has been a popular choice as well as heated transfer media. However, these methods have limitations.

The devastating effects cavitation can have on control valve internals is widely appreciated. In this article, the authors therefore explain the origins of cavitation, provide an easyto-use method to estimate cavitation sound levels and conclude with approaches to reduce or even avoid cavitation.

Heat Tracing

Laying out an effective heat tracing design requires careful attention to detail. Every aspect of the system must be meticulously considered, including both the temperature requirements of the fluids being protected as well as the physical characteristics of the equipment being heat traced.

Instrumentation Fittings

In the world of instrumentation, there are a number of different topics discussed and analyzed.  However, one that should not be overlooked is that of instrumentation fittings. Do you know what technologies are available? Do you know the strengths and /weaknesses? Are there any new trends?

Impedance Heating

Impedance heating systems act much like standard heating circuits, except the resistor is the pipe itself. This is accomplished when a small amount of AC voltage is applied across the terminals. The resulting impedance of the system generates heat on the pipe. The control panel for an impedance system provides power and control. However, the step down transformer is what provides the reduced voltage, 30VAC or less, to the pipe. This rating stays within OSHA and NEC limits.
