NOV MGS-1000 multi-grip slip

Power slips sit in the rotary and hold the drill string when the elevators are open. A multi-grip slip holds more than one pipe diameter without a full slip change, using inserts or a grip range instead of a single-size slip body. The MGS-1000 is NOV’s slip under that name.

It fits the rotary or master bushing it was built for, and the pipe range of its inserts. A public load table for this exact model was not in the onshore section that covers the PS-series slips, so this page does not turn the “1000” into tons. The PS-21, for comparison, publishes load, rotary fit, and operating pressure as separate lines. Ask for those same three on an MGS-1000.

A BX elevator hangs on the links and lifts the string. The slip holds the string in the rotary while the elevator is open. A single-size slip body only fits one pipe OD. The point of a multi-grip slip is that the inserts cover a range. The rotary bowl still has to match. A slip for a 37½-inch table will not drop into a 27½-inch table.

Get the API 7K load rating, the rotary it fits, and the insert range. Look at the inserts. A slip rated for the load, with inserts that do not cover the pipe on the rack, will not hold that string.
