BTS®-4
Integral, Upset, Premium, Production Tubing
The BTS®‑4 is a gas‑tight, two‑step integral joint connection designed for 4.500″ to 5.500″ OD tubulars. Optimized for high‑pressure/high‑temperature operations, it provides high tensile efficiency and robust metal‑to‑metal sealing.

Key Features
- 4‑pitch threads and larger shoulder area (versus BTS®‑6) provide higher torques for extended‑reach operations.
- Non‑interference threadform eliminates galling during multiple make‑and‑breaks.
- Two‑step design with internal and mid‑wall torque shoulders allows deep stabbing and fast running.
- Integral connection design reduces leak paths and eliminates couplings.
- Metal‑to‑metal seal is stronger than the pipe body and proven >100 % gas tight through deviated wells.
