Oil well drilling and well completion, it's longevity and safe operation depends greatly on a good, complete cementing. High quality dual bow spring type centralizer for casing might be the more economical choice. Deviated or fully horizontal casings rely on a proper standoff for a complete cementing which comes from using offer that insurance as they overcome the gravitational and axial forces of a casing.
Our Centralizers are manufactured to closely slide over your casing and have ample clearance between your well bore allowing the it to be inserted more easily and to prevent the string from becoming deferentially stuck. Uncommon sizes are available based on request, welcome.
