Equipment

Fleet and instrumentation

Every figure that is confirmed is published. Every figure that is not is marked TK rather than estimated.

Cryogenic nitrogen pumper unit

One unit covers the rate range and the pressure range, and still fits down a lease road.

Weights are withheld pending client confirmation. The figures on the previous site were transposed.

Sized to the job rather than to one trailer, and rented by the week or the month.

Capacity
Volume range	21,000 to 81,000 ft³
Rental terms	Weekly or monthly

Instrumentation

Two of these run on every test at the same time. All of them are recertified every 6 months.

Two pens on one 12 inch chart, pressure and temperature on the same time base. The chart is a physical artifact that leaves site with the job file.

Runs on the same test as the Barton, on its own power and its own clock. Exports a timestamped log for the integrity file.

Kept because certain standards still call for a deadweight reference and will not accept a digital substitute.

Reads to minus 100°F. The number it returns is what turns a dry line from a claim into a record.

Dryness verification
Range	Reads to −100 °F
Measures	Dew point, relative humidity, surface and air temperature
Output	Logged reading for the job file
Recertification	Every 6 months

Meters volume pumped so fill and displacement volumes reconcile against the calculated line volume.

Volume measurement
Measures	Pumped volume
Use	Fill and displacement reconciliation
Recertification	Every 6 months

Pig types carried
Foam and poly pigs	Cleaning, drying, and product displacement
Gauge pigs	Proving bore and confirming the line is clear for inspection
Brush pigs	Scale, mill scale, and weld slag removal
Smart and MFL pigs	In line inspection runs

Compressor supplied with the run. For lines with no launcher or receiver, a bell piece is fabricated to fit over the opening and act as a launcher.
