Why is a
section on pigging placed in the Chemistry section of your website?
Pigging are very important to the industrial chemist. Although
Pigs are able to decrease the potential of corrosion and plugging of
pipes, you would not be able to pig often enough to keep up with solids
deposition or corrosion rates. Chemistry and pigging are equal and
cooperative partners in the areas of industry. After all, even
pigs are manufactured out of chemicals.
spheres or other circular devices that are used to clean, separate, or
apply material from/to pipelines. Pigs enter one end of the pipeline and
exit at the other end. Chemicals are typically placed in between
two pigs at the beginning of the run, perform the required work during
the run, and exit at the end of the run..
many thousands upon thousands of different types of pigs and
configurations available. Here are a few general examples:
Steel Mandrel Pig
Mandrel Cup Pig
of pigs include: Cup, Disc, Brush, Scraper to name a few.
treatment with both chemicals and pigging are usually much more
effective than chemicals on their own. Pigging ensures that the
chemical is placed along the entire length and circumference of the
pipeline. Corrosion inhibitors, paraffin inhibitors, asphaltene
dispersants, and other chemicals must be in physical contact with the
pipeline material to be effective.
