Technical solutions for corrosive potential

 

Salem Township was confronted in April this year with an incident in the natural gas distribution network. An explosion took place on a network segment, which led to the evacuation of several companies in the area. The distribution activity was stopped to determine the causes.

 

A preliminary investigation shows signs of corrosion on the pipe surface, which " indicates a possible flaw in the coating material ", used for joints in the year of construction (1981).

 

“The preliminary investigation has identified evidence of corrosion along two of the circumferential welds: one at the point of failure and another excavated after PHMSA’s response to the Failure Site. The pattern of corrosion indicates a possible flaw in the coating material applied to girth weld joints following construction welding procedures in the field at that time.”

 

 

The importance of a specialized team

 

Inspections carried out in 2012 "revealed no areas requiring repair or remediation before the next inspection." On this subject, here is an article about organizing periodical inspections. It needs to be carried out by a specialized team. Otherwise, corrosion can be caused by elements who initially did not present a real danger.
