The Integral Elastic Centralizer is made of high quality spring steel 65 Mn steel plate stamping with heat treatment forging. The entirety is weld-free.
- Usage: The centralizer can ensure that the cement ring outside the casing post has a certain thickness, which can reduce the resistance when casing down to avoid sticking the sleeve, and help to improve the cementing quality.
- Principle: The supporting function of the centralizer arch piece achieves the purpose of centering the casing in the cementing process.
- Features: The straight centralizer bar can provide the maximum lateral supporting force.
