Guardian Wellhead Protection & Rentals provides tubing savers and casing savers among its wellhead protection rental equipment.
A single or double piston hydraulic cylinder can be inserted in the main mandrel through the tree and into the wellhead bore. Using this method of wellhead protection, sealing occurs in the ID of the production casing.
Tubing and casing savers can be installed or removed while under pressure, allowing the well to remain active. The average installation or removal time is under an hour.
