In 1958 Harry Girard, a manufacturer of polyurethane
protective enclosures for delicate technical instruments at the time,
provided a California oil company with polyurethane foam cylinders for
removing moisture and debris in natural gas pipelines.
Although these foam cylinders cleaned the pipeline, their effective
life was relatively short. Mr. Girard began the process of developing
a variety of patented coatings
and geometrical shapes to extend the life of
these foam cylinders. Thus was the birth of
a product now recognized throughout the
world pipeline industry as the “Polly-Pig”.
During the next decade many factors contributed to the importance of
pigging pipelines. The proliferation of new pipelines required pigs
specially designed to remove construction debris and prove out the line.
Removal of condensate became an important factor in reducing internal
corrosion as the pipelines aged. The practice of “batching”,
i.e. separating similar products with special pigs, allowed greater
transmission efficiency by eliminating the necessity of completely evacuating
the pipeline to change product. Older pipelines began to require very
aggressive pigging to remove internal deposits which were restricting
flow and dramatically increasing transmission energy costs. These new
demands lead Harry Girard to create his own company Girard Industries
as a pipeline pig manufacturer.
Girard Industries began with the Polly-pig and has since developed
and manufactured new pigging products to meet the demands of a changing
industry. From natural gas and hydrocarbon pipelines to water and special
application pipelines, Girard can provide technical assistance and the
specific pig to accomplish the most difficult of tasks.
