Single Vane Welded Bow Spring Centralizer
Made of 65Mn steel which is better tensile strength than general steel,but it is not up API standard,so we need process them by heat treatment in the high temperature and then annealing treatment in the cool water with special chemical material .What we do is to ensure the bow higher restoring force.This kinds of heat treated bow provides good centralization in the well when in fast running casing.
Single Vane Welded Bow Spring Centralizer Features
- Vertical or slightly deviated wells
- Single crest or double crest
- Under reamed and washed-out wells.
- The high-quality, spring-steel bows are heat treated to optimize standoff in gauge holes, under reamed holes
- Various bow shapes and heights are available to provide optimum restoring forces for most well requirements.
