Two Basic Types

Swab Mandrels from Oil States are available for use with wire or "all-rubber" type swab cups. Wire type tubing and drill pipe swab cups
(1-1/4" through 3-1/2") can be used on the "all-rubber" type mandrels by utilizing sleeves available from Oil States.

Maximum Fluid By-Pass

Tubing and drill pipe mandrels are fluted, allowing maximum fluid by-pass while lowering the mandrel to swabbing depth. Steel mandrels are either machined or drop forged from high strength alloy steel. All mandrels exceed strength requirements for wire rope sizes recommended for use with mandrels.
