Inspection Services

Often time your facility will require a natural gas pipeline inspection by a licensed contractor in Arizona that may be required by the Arizona Corporation Commission. If your Apartment complex, commercial business complex or RV Park has a master meter you will need to have an annual master meter natural gas inspection completed in addition to quarterly inspections as well for ACC compliance. RP Gas Piping can complete your Annual Master Meter Inspection and can completed any repairs if necessary to make you ACC compliant.

  • Odor Tests
  • Proper Valve Operation

  • Below Ground Piping Inspection
  • Leak Survey
  • Gas System Mapping
  • Line locating
  • Cathodic Protection Reads

Cathodic Protection testing is a requirement by the Arizona Corporation Commission that will be a part of our annual inspection that we will conduction for you. Cathodic protection testing and anode replacements is also a requirement for any underground propane tanks that have been installed on your property. Cathodic protection or CP is the most common way to protect your underground propane tank or metallic gas piping below grade from corrosion or rust in Arizona. Cathodic protection is a technique used to control the corrosion of a metal surface by making the metal in the ground the cathode by installing an Anode to it. A simple method of protection connects protected metal to a more easily corroded “sacrificial metal” to act as the anode. The sacrificial metal then corrodes instead of the protected metal.
