All our smart tool barrels are rated ANSI 600. Our cleaning barrels are built to ANSI 150.

Marler carries an extensive fleet of adapters and pipe. We can custom fit our temporary equipment to your permanent piping configuration.

We carry cleaning and smart tool barrels up to 30" diameter, and extension spools to 36".

We carry an extensive stock of Apache pipeline pigs, and can supply them directly for your project.

Pigging Basics

Tool tracking is where a tracker or team of trackers follow a cleaning, gauge or smart tool from launch to receive.

The trackers use AGM's, geophones, and transmitter/receivers to understand the position of the pig in the line. The information is shared with the pipeline operator.

An AGM is an "above ground marker". It is an electronic device that very accurately detects the passage of a pipeline tool. It can be triggered with either a transmitter signal, or magnetic field on an MFL (magnetic flux leakage) tool.

When used in conjunction with a smart tool, the AGM's are placed very accurately in surveyed locations, and the data of the tool passage is used to "map" the line geographically.

Tools need to be tracked so the pipeline operator knows if the tool is continuing to move through the pipeline without issue.

Additionally, the tool may be tracked with AGM's at surveyed sites in conjunction with an in-line inspection with a smart tool, to tie in geographical data.

The more accurately the locations for AGM's are surveyed, the more accurate the data tied to a smart tool run becomes. This allows the operator to accurately pinpoint dig locations for defect verification and remediation.

Marler has developed a safe and efficient method for introducing liquids into a gas pipeline for the purpose of cleaning the line. Please reach out to us through the website, or give us a call to discuss.

Smart tools, sometimes called intelligent tools, require differing levels of pipeline cleanliness. For instance, MFL (magnetic flux leakage) tools require less cleaning than a UT (Ultrasonic) tool, however, with the MFL tool, you must ensure there is little or no ferrous material in the line, where the main concern for UT is eliminating as much, if not all debris in the line. Marler understands the difference in levels of cleanliness, and type of cleaning required for the various types of In-Line Inspection tools.

Yes. Smart tools are considerably longer than cleaning and gauge tools, and therefore require longer oversize barrels at launch, and a nominal that is equal or greater than the length of the smart tool at receive.

Yes. Temporary piping must be engineered to the same standard as permanent piping.
