Mustang Certiprobe® Sample Extractor

The Mustang Certiprobe® flanged sample extractor is the initial access point for a sampling system.

The Mustang Certiprobe flanged sample extractor can be used within a Liquefied Natural Gas or Cryogenic pipeline or vessel. The Certiprobe is available in a variety of lengths, materials and pressure ratings to accommodate a wide range of applications in flanged configurations.

The Mustang Certiprobe flanged sample extractor design includes Nondestructive Examination (NDE) of Positive Material Identification (PMI) and Dye Penetrant Inspection (DPI) for all welds. Stress analysis is performed, using pipeline conditions, prior to pipeline installation.
