CAVINS
“ADVANCE”
SPIDERS
The Cavins “Full Circle” Slips,
(Type “FCR”) with removable inserts
were designed to replace Full Circle
Slips with integral teeth. The “FCR”
Full Circle Slips surround the pipe
360 degrees and exert a uniform grip-
ping power on the pipe to avoid defor-
mation, bottle-necking, or crushing. A
heavy-duty steel pin retains each insert
securely in each slip body segment. The cot-
ter key secures the retaining pin in place.
THREE DISTINCT ADVANTAGES ARE REALIZED WITH THIS NEW DESIGN:
1. It eliminates the purchase of individual slips for every size of tubular goods.
2. The Slip Body is made of tough alloy steel for maximum strength while the
inserts are of case hardened steel for longer wear.
3. Since only a minimum of Slip Bodies are required to cover the range of
tubular goods for each spider, the investment compares less than it would
with the purchase of individual slips for each size pipe.
For the Cavins “Advance” Model “B” Spider, only one type “FCR” Slip
Body is required, with removable inserts, (TYPE “FCI”). One set of (4) inserts
is required for each size of Tubular Goods:
The 2-7/8", Type “FCR” Master Slip Body takes inserts for 2-7/8", 2-
3/8", 2-1/16", 1.900 (1-1/2"), 1.660 (1-1/4"), and 1.315 (1") O.D. tubular
goods.
To handle 3-1/2" O.D. Tubing, it is necessary to use a Type “TD” Slip
Body with either Chevron, (Type “CI”) Replaceable Inserts or button
(Type “CBI”) Replaceable Inserts.
For the Cavins “Advance” Model “C” and “C-HD” Spiders, three (3)
types of “FCR” Slip Bodies are available with Removable Inserts, (Type “FCI”).
