Permanent Gauge Welded Mandrel

Export as PDF
SKU: AN001-050-205
  • Description

Description

The permanent gauge welded mandrel is designed to connect the gauge onto the production tubing and to provide a path for the gauge to measure the internal tubing pressure.  The tubing pressure is measured via a port leading to the inside of the production tubing. During the installation of the gauge, the mandrel provides full protection for the gauge and the cable head.

The mandrel design makes it suitable for both single and dual pressure permanent gauges.  The I.D of the mandrel is the same as the production tubing; the OD can vary depending on the tubing and casing size. All designs are made to meet production-tubing specifications and manufactured in accordance to API 5CT, the tables below provide details for the 3 most common welded mandrel sizes.
