TEC-LOCKTM BTC connection system is a close-tolerance threadform with shouldering pin noses that eliminate the open “J” area, creating a flush ID for turbulent free flow and reduced tool hang ups. The pin-to-pin contact is excellent for rotating casing downhole and enhancing connection integrity. Ideal for extended reach horizontal applications requiring high bending, compressive and torsional resistance.
