Product Description

API 7"* 8 1/2" Casing Centralizer for Oilfield

The Non Weld Bow Centralizers is developed to exceed API specifications for use in most 
demanding conditions. Premium quality Bows made of special
 65Mn steel (Alloy steel request is available) with uniform hardness provide optimum performance. 

The bows with extended profile prevent them from hitting against casing collars. The bows are available in a range to accommodate any well profile. Quality steel and non weld design ensure extra strong grip while integral hinges folded on the inside are connected by high strength locking pin for maximum structural robustness. 

Non weld bow centralizers are used to position the casing in the center of the wellbore in vertical. The non weld bow centralizers reduce the effect of channeling by improving cement flow. This results in a more uniform thickness between the casing and the wellbore. 

By reducing the pipe movement before the cement sets in, the centralizers are able to minimize gas channeling. The centralizers provide a semi rigid casing standoff.
