A close-tolerance threadform with shouldering pin noses that eliminate the open “J” area
TEC-LOCK™ BTC-S connection system is a close-tolerance threadform with shouldering pin noses that eliminate the open “J” area
It creates a flush ID for turbulent free flow and reduced tool hang ups.
The integral shoulder is excellent for rotating casing downhole and enhancing connection integrity while eliminating coupling rotation on the mill-end. Ideal for extended reach horizontal applications requiring high bending, compressive and torsional resistance.
Available in sizes ranging from 4.500 in. to 13.375 in.
