Gas Line Corrosion Control
In Western Pennsylvania and the tri-state area, gas pipelines are subject to all of the stresses that severe weather can offer. They endure cracking, embrittlement, microbial influenced corrosion (MIC) sulfide corrosion, oxidation, and hydrogen induced cracking. Then there are internal threats, including flow induced corrosion and interior pitting.
Within the last 10 years, the U.S. Department of Transportation Office of Pipeline Safety has conducted studies showing that internal pipeline corrosion by itself has caused approximately 15% of all reportable incidents affecting gas transmission pipelines. This results in an average annual loss of over $3 million and has led to accidents and fatalities.

Today, more effective corrosion inhibitors are available than ever before, including hydrocarbon-soluble inhibitors that protect against corrosion under a wide variety of operating conditions.
Cathodic protection is another technique that works to control the corrosion of a metal surface by making it the cathode of an electrochemical cell while a sacrificial metal becomes the anode. This technique can be employed as either a passive galvanic system or one where DC electrical power is used to enhance the effect (typically used in the case of long pipelines).
The cost replacing gas pipelines, from the permitting stage through the work of locating and digging up existing infrastructure can be enormous. At Banks Gas, our corrosion protection methods are designed to protect and preserve aging but still critical high-pressure steel pipelines.
Exposed Pipe Inspection and Repair
Exposed gas pipelines are no less vulnerable to weathering and corrosion. Our experienced inspection teams are trained to detect problems at their earliest stage or deal with corrosion issues at their worst.
