7″ x 7″ Slip Insert for Varco Style Slips | Part 20173
The 7″ x 7″ Slip Insert (Pan P/N: 20173) is a precision-engineered gripping component designed for heavy-duty casing operations. Specifically manufactured for 7″ Slips handling 7″ OD Casing, these inserts are the industry standard for Varco Style RSLG and compatible rotary slips. Forged from high-grade alloy steel and heat-treated to API 7K specifications, they provide the critical balance of surface hardness and core toughness required to support heavy casing strings.
Description
Technical & Engineering Data
Advanced Load-Bearing Design
Casing inserts face immense axial loads. Our 7″ inserts are engineered to prevent pipe damage while maintaining a fail-safe grip:
Uniform Tooth Profile: The precision-machined teeth are designed to provide maximum surface contact, preventing “bottlenecking” or crushing of the casing wall.
Metallurgical Excellence: CNC-machined from forged 8620 alloy steel and case-hardened to 58-62 HRC. This ensures the teeth remain sharp under thousands of tons of vertical pressure.
Impact Resistance: A specialized tempering process ensures the insert core remains ductile, allowing it to absorb the “shock” when slips are set without cracking or shattering.
