Hinged Welded Single Crest Centralizer


Positive bow centralizer is used for both casing and tubing applications that require concentric casing strings.

In deviated cased holes, the centralizer significantly reduces frictional drag and can provide nearly 100% standoff.

  • Single crest or double crest
  • Vertical or slightly deviated wells
  • 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.
