Spring Casing Centralizer Introduction
The welded elastic centralizer has the characteristics of simple
structure, safety and reliability, high strength, good spring
performance and convenient use on site;
According to the detection of the casing centralizer inspection and
research center of the Petroleum Gas Company, the righting force of
the centralizer has increased by more than four times in the API
standard in the case that the power is not exceeded, which has the
advantages of small power and large positive force. The necessary
guarantee for improving the quality of cementing can be widely used
in the casing construction of vertical or inclined wells.
The structural diagram of the welded elastic centralizer is as
follows. The basic components are composed of a round hoop, a
single arcuate spring piece and a pin. Each type of centralizer is
composed of corresponding bow springs. The material of the bow
spring is 65Mn. After forming heat treatment, it meets the
requirements of the Standard for Casing Centralizer. It has high
strength, small deformation and reliable locking.
. Produced and tested to meet API 10D specification .
. Robust single piece design, suitable for onshore installation
. Tiny starting forces and restoring forces are much great than API
standard .
. Flexible design reduces running forces through any cased hole
restrictions, has an extremely low co-efficient of friction, speed
the process of running casing liners to final depth.
