Impero Petro Tools Pvt. Ltd. products

Slip on welded centralizers are manufactured with solid end rings that can be easily slipped on the casing OD during installation. Slip-on welded centralizers are designed for high restoring force combined with low starting force for centralizing the casing pipe. High performance characteristics are combined with easy field assembly. Bow springs are manufactured of high-quality alloy steel, hot bent to shape using dyes and then heat treated under controlled temp and time cycles for consistent spring characteristics to ensure a crack free weld with a minimum amount of distortion and maximum amount of rigidity.

Impero’s Hinged Non-Welded Semi Rigid Bow Spring Centralizer is engineered to meet API 10 D standards and specifications, allowing them to withstand all conditions.

Hinged Welded Semi Rigid Centralizer ensures high efficiency in casing. Welded centralizer has more restoring force as compared to Non-Weld Centralizer. The Centralizers have double crested bow spring strongly welded to the end collar under required temperature and condition with extra low hydrogen coated electrodes, which assures ultimate strength and uniformity in every weld. Integral hinge folded on the inside stay intact even under extreme stress. The End Collars are designed with a reinforcing rib stamped into the end collar to give maximum structural toughness.

Slip On Welded Semi-Rigid Centralizers share many of the same design and operational features as Hinged Welded Centralizers. They can be directly installed onto pipe and works best with set screw style stop collars to increase the holding force. The collars are innovatively designed with roll formed peripheral ridges that provide extra rigidity.

Non-Welded Positive Centralizers are uniquely designed with flat bottom U profile of different depths. The Centralizers significantly reduce frictional drag while being used in deviated holes. They provide almost 100% Stand Off when run inside a cased hole. They are supplied 1/4″ or 6 mm less than the inside diameter of the hole size in which Centralizer is to be run. This design eliminates weak (brittle) spots passage. The flat U profile is fitted in self-locking retaining lips for firm and positive hold.

Hinged Welded Positive Bow Centralizers have strongly welded to the end collar under required temperature and condition with extra low hydrogen coated electrodes. Operational and general design features are the same as non-welded positive bow centralizer.

Float Shoe is a cylindrical steel  section with a rounded nose which guides the casing toward the that is  attached to the bottom of the casing string towards the center of the hole.  It contains a check valve/ poppet valve to permit  fluid to pass downward but not  upward through the casing.

Float Collar is a cylindrical steel section with box and pin threads. Float Collar generally uses one string above the Float Shoe. It contains a check valve/ poppet valve to permit fluid to pass downward but not upward through the casing and provides a flat landing surface for cementing plugs.
