Hello Pipe Enthusiasts!
As a vital part of energy infrastructure, steel pipes serve in exploration, structural support, casing, production, transmission, and distribution of oil and gas. PT Bakrie Pipe Industries (BPI) provides a range of welded steel pipes tailored to technical needs in this sector, from high-pressure systems to structural support for drilling operations.
Main Functions of Steel Pipes in Oil & Gas
- Flowline & Gathering Line
Used to transport crude oil or gas from wells to initial processing facilities.
- Transmission Pipeline
Used for long-distance transport (interconnecting production facilities to refineries or export terminals). Requires large diameter and high-strength pipes.
- Process Piping
Installed in refinery or plant areas, carrying process fluids (high-pressure, extreme temperatures, sometimes corrosive).
- Casing & Conductor Pipe
Used to support drilling structures, ground casing, and protect wells from formation collapse.
- Structural Pipe for Offshore & Onshore Facility
As pipe bridge columns, platform legs, offshore production support structures, and subsea construction components.
