Type C Full Circle Spider Inserts | 82.5-Ton Tubing Protection | Pan Industries
The Pan Industries Type C Full Circle Insert (FCI) is engineered for the precision handling of production tubing and small-diameter drill pipe. Designed for use in Model C Pneumatic and Manual Spiders, these inserts provide a continuous 360-degree radial grip around the tubular. Unlike standard slips that can cause “point-loading,” the Pan FCI design distributes the 82.5-ton (165,000 lbs) hook load evenly, virtually eliminating the risk of “bottlenecking” or crushing thin-walled tubing strings during workover and well-servicing operations.
Description
Technical & Engineering Data
Why “Full Circle” Grip Defeats Standard Slips
In modern well completions, tubing integrity is paramount. Pan Type C inserts offer a mechanical advantage:
Uniform Load Distribution: The circular geometry ensures 100% contact area. This is critical when handling J-55, L-80, or P-110 grade tubing where localized stress risers can lead to premature string failure.
Forged 8620 Metallurgy: Every insert is CNC-machined from forged alloy steel, providing superior grain flow and impact resistance compared to cast alternatives.
Advanced Case-Hardening: Heat-treated to 58-62 HRC with a controlled depth, ensuring the pyramid teeth maintain an aggressive “bite” through heavy paraffin, scale, and drilling fluids.
Interchangeability: 100% compatible with Cavins “Advance” Model C spider bodies and equivalent slip-type spider
