Thefollowing is a list of resources and calculators designed to assist you in your pigging and corrosion endeavors. Using the calculators you can determine everything from pig speeds to the amount of wax tape required to wrap a certain size pipe. Also included are helpful formulas and an “FAQ’s” page which will provide you with useful tips about pigging pipelines.

This calculator will help you determine the amount of wax tape and primer needed to wrap certain size flanges.

Notes: The above information is to be used as guidelines only and not to be considered absolutes. A number of factors can vary the above information including type of product, temperature, viscosity and type of pig being used.

*Numbers shown above for Gaseous flow assume no line pressure and only uses the gas to move pig. For accurate calculations on velocity of gas in feet per second we recommend using the following formula:

Pigging in the context of pipelines refers to the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. This is done without stopping the flow of the product in the pipeline.

These operations include but are not limited to cleaning and inspecting the pipeline.
