Varco Style 2626 Button Die for 18-5/8″ CMS-XL Slips | Pan P/N 20226
The Varco Style 2626 Button Die (Pan P/N: 20226) is a specialized circular gripping insert engineered for the unique curvature and load requirements of 18-5/8″ OD casing. Installed in high-capacity CMS-XL (Extra Long) Casing Slips, these buttons provide a multi-point mechanical lock necessary for supporting massive axial loads. Manufactured from forged 8620 alloy steel, the 2626 series is the industry standard for durability and casing wall protection during intermediate well-section construction.
Description
Technical & Engineering Data
Engineered for Massive Casing Strings
Handling 18-5/8″ casing involves managing immense vertical pressure. Pan 2626 buttons are designed for performance under these extreme conditions:
High-Capacity Load Distribution: The 1/2-inch thickness profile is precision-ground to ensure all 300 buttons in a standard CMS-XL assembly engage the pipe simultaneously. This prevents localized stress risers that can lead to casing deformation.
Deep-Case Carburization: Surface-hardened to 58-62 HRC, the pyramid tooth geometry maintains its “bite” even when encountering heavy mill scale or hardened protective coatings on the casing surface.
Structural Resilience: While the biting surface is ultra-hard, the core remains ductile to absorb the impact of the slips “setting” under a hundreds-of-tons load, preventing button-shatter.
