Non Weld Bow Centralizers (S 10)

Steelfabs Non Weld Bow Centralizers are high quality, developed to exceed API 10 D specifications for use in most demanding conditions. The Non Weld Bow Centralizers combine the highest Non Weld Centralizer restoring force with the lowest starting force. Premium quality Bows made of special alloy steel 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. 

Steelfabs non weld bow centralizers are used to position the casing in the centre of the wellbore in vertical, deviated as well as horizontal wells. 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. Non weld design features self locking of lips forholding bows to end collars.

Bows of special alloy steel are hot formed and tempered for optimum strength, resilience and uniformity. They are then flattened as per specifications for consistent performance. High restoring force combined with low starting force is achieved with all 5 bow heights. Their installation on the casing pipe is very convenient.

It requires only the placement of the two assembled halves on the pipe and iinserting the pin in the end collar hinge. The centralizer when unassembled makes a compact package, greatly reducing shipping cost. Assembly at site is conveniently done, hydraulically or pneumatically. 

The non weld bow centralizers are available in sizes 4½" to 24".
