Job Description

Pipeline inspectors are responsible for establishing the quality and proficiency of a pipeline system. Inspectors must always abide by public safety guidelines and follow all environmental regulations in order to promote a secure environment around the piping system. Verification that all building codes, specifications, and procedures are being met is a vital part of the position.


A pipeline inspector has a variety of duties including measuring the depth and alignment of trenches and examining the trenches for stones or debris that may damage the pipeline. An inspector may also collect data and information on the surrounding area for possible corrosion factors. A pipeline inspector may do mechanical particle testing of exposed portions of the pipeline and mapping and measurement of metal loss on the system.

Inspectors may perform visual inspections while others perform electronic inspections by using x-ray, ultrasonic, magnetic particle, or electronic crawler inspection methods. Some inspectors use devices called pigs (pipeline inspections gauges), which travel through the pipeline and collect and transmit data using a small computer placed inside of them. Inspectors often must take photo and written documentation of the system and any repairs or assessments
