API Oil Drilling Equipment Non-Welded Spring Bow Centralizer for Casing
Spring Bow Centralizer
Spring Bow Centralizer is used to help center the casing in wellbore, allowing even distribution of the cement around casing during cementing operations. Spring Bow Centralizer has high restoring capacity, which is determined by the shape and stiffness of its bows.
Non-welded Spring Bow Centralizer has smooth continuous bow profile and lack of hinged collar. It is used in most types of well designs and wells with less stringent well design requirements, when increased structural integrity is required, and used in close tolerance well designs.
Features
• The end collars are slip on types for maximum structural toughness;
• Mostly be used in vertical or slightly deviated wells;
• Be anti-corrosive after special coating process;
• Has high restoring force and low starting and running force;
• Be capable to pass through narrow hole sections and expand in the targeted locations.
