Welded Bow Spring Centralizer

Hinged Welded Semi-Rigid Bow Spring Centralizer

EOT’s Hinged Welded Semi-Rigid Bow Spring Centralizers are designed to enhance the efficiency of casing operations, especially in challenging wellbore conditions. With a robust welded construction, these centralizers offer higher restoring force compared to non-welded variants, ensuring superior performance in maintaining centralization during cementing operations.

Features:

• Welded Bow Springs: Double-crested bow springs are strongly welded to the end collars using low-hydrogen-coated electrodes for exceptional strength and uniformity.
• High Restoring Force: Welded design provides greater restoring force, improving stand-off in deviated and horizontal wells.
• Integral Hinge Design: The folded hinges remain intact under extreme stress, enhancing durability.
• Reinforced End Collars: End collars are stamped with a reinforcing rib for maximum structural toughness and reliability.
• Corrosion Resistance: Treated with iron phosphate coating and finished with a durable polyester powder coating to prevent rust and corrosion.
• Efficient Shipping: Shipped in a half-assembled condition to reduce shipping and storage costs.
• Bow Configuration Options: Available with a choice of four standard bow heights for optimal starting and restoring force.

Options:

• Size Range: Available in all sizes from 2 7/8″ to 30″, with custom sizes or combinations available upon request.

EOT’s Hinged Welded Semi-Rigid Bow Spring Centralizers are a reliable choice for maintaining optimal centralization in both vertical and horizontal wells. Their durable design, high restoring force, and corrosion-resistant features make them a cost-effective solution for demanding casing operations.

Hinged Welded Bow Spring Turbolizer

EOT’s Hinged Welded Bow Spring Turbolizer is engineered to optimize cement displacement by inducing a spiral flow pattern in the slurry, enhancing overall efficiency and wellbore cleanliness.

Key Features:

• Turbulence Induction: Deflector blades on the bow springs create a spiral flow for improved displacement and cement slurry distribution.
• Durable Welded Construction: Bow springs are welded to the end collars using extra-low hydrogen-coated electrodes, ensuring uniform strength and durability.
• Reinforced End Collars: Designed with a stamped reinforcing rib for superior structural toughness, ensuring reliability in challenging conditions.
• Flexible Spring Blades: Heat-treated spring steel blades minimize damage during downhole movement while improving drilling fluid cleaning action.
• Built-in Stop Device: Prevents over-extension and ensures precise positioning on the casing.
• Rust and Corrosion Resistance: Treated with an iron phosphate coating followed by a polyester powder coating for long-term durability.

Applications:

• Suitable for vertical, deviated, and horizontal wells.
• Enhances cementing operations by improving fluid flow and preventing channeling.

Size Availability:

• Available in sizes ranging from 2 7/8″ to 30″.
• Custom sizes and configurations can be manufactured upon request.

EOT’s Hinged Welded Bow Spring Turbolizer combines robust design with advanced functionality, ensuring reliable performance and optimal cementing outcomes.
