7-5/8″ x 7″ Slip Insert for Varco Style Slips | Part 2623
The 7-5/8″ x 7″ Slip Insert is a heavy-duty reduction insert engineered to adapt 7-5/8″ rotary and casing slips for the secure handling of 7″ OD tubulars. Designed for Varco Style high-capacity slips, these inserts feature a 3/4″ thickness profile to ensure perfect circularity and grip. Manufactured from forged alloy steel and heat-treated to API 7K standards, they provide the essential mechanical bite required to support heavy casing strings during makeup and breakout.
Description
Comprehensive Technical Data
Large-Diameter Load Engineering
Supporting a 7-inch casing string requires an insert that can handle massive axial loads without compromising the pipe wall:
Anti-Bottlenecking Design: The tooth profile is precision-machined to distribute radial clamping forces evenly across the larger surface area of the 7″ casing, preventing localized deformation.
Superior Metallurgy: CNC-machined from forged 8620 alloy steel, offering a denser grain structure and higher impact resistance than standard cast alternatives.
Specialized Heat Treatment: Every insert undergoes a rigorous carburization and tempering process, resulting in a surface hardness of 58-62 HRC for long-term wear resistance and a ductile core to prevent brittle fracturing.

Equipment Compatibility
Varco Style Casing Slips: Specifically designed for large-body rotary slips requiring 3/4″ thickness reduction inserts.
Heavy-Duty Drilling Rigs: Ideal for deep-hole casing runs where 7-5/8″ slip bodies are the rig floor standard.
Global Interchangeability: Fits most major brand 7-5/8″ slips requiring 2-3/4″ length inserts for 7″ OD pipe.
Key Performance Advantages
Optimized Grip Consistency: Engineered to penetrate through pipe scale, rust, and heavy drilling mud for a fail-safe mechanical lock.
Enhanced Casing Protection: Controlled tooth penetration ensures a secure hold while preserving the structural integrity of expensive casing strings.
Precision Seating: Machined to exact tolerances to prevent “insert roll” or vibration within the slip body under extreme torque.
Corrosion Defense: Finished with a protective industrial coating to withstand offshore salt spray and high-humidity environments.
