Parveen manufactures both standard as well as high strength conventional mand-rels. Parveen's high strength mandrels have the benefit of :
1. Can withstand pull load of over 60 Metric Tonnes.
2. Tested hydraulically to 8000 PSI.
3. Tapered lugs to provide easy running.
4. Bore size to match with tubing speci-fications.

Mandrels for gas lift valves have a two fold function - first, they provide a convenient fitting on which to install a gas lift valve as an integral part of a tubing string and second, these help pass the gas through the valves in the proper direction.

Ordering Information:
1. Determine the type of mandrel required based on the casing and tubing sizes and the type gas lift valve being used to the application.
2. Specify tubing size, thread and grade required for the application.
3. Valve adapters and/or thread adapters are sometimes required. Please include these when applicable.
