Bowls / Slips
If you’re working in the oil industry, you know just how important bowls and slips are to the drilling process. These components work hand-in-hand to support and secure drill pipe during every stage of your operation, helping keep your crew safe and your project on track.
Bowls
The bowl is a tapered, funnel-shaped device you’ll find in the rotary table or on the rig floor. Here’s what sets it apart:
- Features a conical internal profile with a tapered inner surface
- Constructed from hardened steel to handle the extreme weights and forces encountered on site
- Specifically designed to house and activate the slips
Slips
Slips are wedge-shaped devices that fit perfectly into the bowl. Here’s what you can expect from them:
- Segmented into 3-4 pieces, making it easy to place them around the drill pipe
- Equipped with teeth or dies on the inner surface for a secure grip on the pipe
- Tapered outer surface to match the bowl’s internal profile
How They Work Together
When you insert the slips into the bowl around the drill pipe and let them move downward, the tapered design creates a wedging action. As the slips slide down the bowl’s surface, they’re pushed inward against the pipe. The heavier the pipe, the tighter the grip—giving you confidence that your equipment is secure.
Primary Uses
- Supporting the drill string weight during connections
- Holding the pipe steady while adding or removing sections
- Preventing the drill string from dropping into the wellbore
- Securing the pipe throughout various drilling operations
- Providing a stable platform for tasks like makeup and breakout of connections
This system plays a vital role in safe drilling operations. It holds pipe strings weighing hundreds of thousands of pounds, all while allowing your crew to handle pipe efficiently and with confidence.
