Bow type Casing Centralizer
The bow springs of this centralizer have two types as follow:
non-welded single bow spring centralizer and non-welded double bows
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.
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.
These Centralizers are designed for High Restoring Forse and Low
Starting Force for centralizing the casing pipe
in a Vertical,Horizontal and Deviated well.
They are available in 4 1/2”-20” sizes.
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
End Collars are designed with self-locking action,which are easy to
assemble,time saver and are having strong grip.
The five standard size Bows can configure to any hole dia.
These Bows with extended profile prevent them from hitting against
These Centralizers undergo a special iron phosphate coating process
to prevent them from rust.
These can be shipped in half assembled condition for economical in
shipping and storage cost.
