Bow Spring Centralizer, Hinged / Slip-on // Outer Diameter 4 1/2" Type Hinged Non-welded

Hinged non weld bow-spring centralizers centralize casing or tubing in the wellbore during running and cementing operations.

The high-quality, spring- steel bows are attached to integrated, hinged end collars with locking tabs.

The hinged design enables the end collars to be latched onto casing over a stop collar, if desired, for easy installation.

The centralizer should preferably be fitted over a stop collar to facilitate pulling the tool in and out of the wellbore.

The Hinged non weld design provides reliable down hole performance in cased-hole or open hole applications.

The bows provide maximum standoff to achieve efficient displacement of mud and cement.

Hinged Non weld bow-spring centralizers are available in several bow heights and sizes to ensure optimum restoring force and provide in a variety of bow configurations for special applications.

All common centralizer sizes have been tested and Validated to meet API Specification 10D for providing reliability and durability during operations.

Bow configurations are available in various heights and sizes suitable for most applications.

Welded Slip On Spring Bow Centralizers share all the operational and design features of Hinged Welded Centralizers.

The key difference is that the End Collars do not have hinges and instead ‘slip’ onto the casing.

The collars are specially designed with roll-formed peripheral ridges that provide extra rigidity and can be accompanied by set screws for elimination of Stop Collars.

Welded Spring Bow Centralizers are high quality welded products, which meet or exceed API 10D specifications.

They are designed for high restoring forces combined with low starting forces essential for centralizing casing pipes.

They are manufactured and heat-treated under controlled temperature and time cycles ensuring that the Bow Springs are strongly welded to the End Collar.

This ensures minimum distortion and maximum rigidity and integral hinges folded on the inside stay intact even under extreme stress.

In addition, the End Collars are designed with a reinforcing rib stamped into the End Collar to ensure maximum strength.
