Oilfield tools Centralizer PC-245 / 295-320 for centering casing strings
Casing centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the casing centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.
The bow springs of this centralizer have two types as follow: non-welded single bow spring centralizers and non-welded double bow spring centralizer. The centralizer are attached to the end rings without welding. The bow spring casing centralizer bow end is connected to the end rings with a locking tab that bears the load force on the centralizer. The centralizers are supplied in hinged segments joined by hinge pins in each segment. All non-welded centralizers meet or exceed the requirements of API Specification 10D, which dictates the minimum restoring and maximum starting forces for centralizers for various casing / hole size combinations.
1). Designed for high restoring force and low running force.
(2). End collars are designed with self-locking action, which are easy to assemble.
(3). Undergo special coating process to prevent from rust.
(4). Can be shipped in half assembled condition for economy in shipping and storage costs.
(5). All products conform to API 10D production specifications.
(6). Our product can be run in vertical, highly-deviated and horizontal wells.
(7). We can produce all types of centralizers: solid body type, positive type, welded spiral type, non-welded type, double bow type and so on.
(8). All products are equipped with stop rings.
(9). They are available in 4 1/2” to 20” sizes.
(10). Premium quality bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over and good spring grip.
(11). End collars are designed with self-locking action, which are easy to assemble, time saver and are having strong grip.
(12). The five standard size bows can con figure to any hole dia.
(13). These bows with extended profile prevent them from hitting against casing collars.
(14). These centralizers undergo a special iron phosphate coating process to prevent them from rust.
(15). These can be shipped in half assembled condition for economical in shipping and storage cost.
(1). The non-welded bow spring centralizers are made under the state of art engineering techniques and rugged quality system. They are developed to exceed API 10D Specification to be used under most demanding condition.
(2). These centralizers are designed for high restoring force and low starting force for centralizing the casing pipe in a vertical, horizontal and deviated well.
