3-1/2″ x 3-1/2″ Slip Insert for Varco Style Slips | Part 20162
The 3-1/2″ x 3-1/2″ Slip Insert (Pan P/N: 20162) is a precision-engineered gripping component designed for the secure handling of 3-1/2″ OD drill pipe and tubing. Optimized for Varco Style RSST (Short) and RSMD (Medium) slips, these inserts are manufactured from high-grade forged alloy steel. Every insert is heat-treated to API 7K standards, providing the ideal combination of surface hardness for a powerful mechanical bite and core toughness to support full string weight.
Description
Comprehensive Technical Data
Balanced Grip Engineering
Handling 3-1/2″ pipe requires a consistent, non-slip interface to prevent localized stress. Our 20162 series is engineered for:
True-Fit Geometry: Precision-machined to 1/2″ thickness to ensure the slip maintains perfect circularity around the pipe, preventing “bottlenecking.”
Advanced Metallurgy: CNC-machined from forged 8620 alloy steel, ensuring superior grain structure and impact resistance compared to standard cast parts.
Controlled Case-Hardening: Surface hardened to 58-62 HRC. This ensures the teeth maintain their aggressive biting edge through thousands of connections while the inner core remains ductile.
