Product Application
Hinged Welded Semi-rigid Centralizer ensures high efficiency in casing. Welded Centralizer has more Restoring Force as compare 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 stays intact even under extreme stress. The End Collars are designed with a reinforcing Rib stamped into the End Collar to give maximum structural toughness. These generally shipped in half-assembled conditions for economy in shipping and storage costs. These Centralizers are available with a combination of Bows configure from choice of four standard Bow height for optimum starting and Restoring Force. These centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder. These are available in all sizes ranging from 3 1/2" to 20". Any special sizes or combinations can available on request.
