“ULTRAFLUSH™ Centralizer Sub

Expro’s Exclusive ULTRAFLUSH™ Centralizer Sub

Expro’s ULTRAFLUSH™ Centralizer Sub design offers a unique solution for centralizing and cementing casing and tubing ranging from 4-1/2” to 22” in diameter. This centralizer can pass through the most restricted sections thanks to its bows that can be fully compressed against the tool body. The ULTRAFLUSH™ Centralizer Sub provides full rotation capability, optimizing performance in both tight-hole and underreamed wellbore conditions. All models and sizes feature a rotating design, enabling the casing or tubing to be rotated to bottom or during cementing operations. The continuous welded construction between the end bands and the bows ensures durability and reliability, allowing operators to efficiently reach the planned setting depth.

Features and Benefits

  • Rounded Bow Design: Bows are compressed tightly against the tool body, allowing the centralizer to pass smoothly through narrow restrictions while improving formation-to-formation separation.

  • Proprietary Machined End Bands: Facilitate easy running in and pulling out of the wellbore, reducing the risk of casing sticking and avoiding significant costs associated with fishing operations.

  • Lubrication Port: Integrated lubrication port ensures smooth rotation and prevents corrosion between the body and end bands.

  • API 10D-Compliant Bows: Proprietary design meets or exceeds API 10D standards, enhancing centralization performance in underreamed holes and reducing the risks and costs related to remedial cementing operations.

  • Full-ID Centralizer Body: Maintains the internal diameter (ID) requirements of the current casing string and previous casing strings, while meeting or exceeding burst and collapse ratings, ensuring the structural integrity of the casing string.
