PTFE Tapes & Sealents - Where to use and avoid in Oil & Gas Offshore Industries?
PTFE Tapes & Sealents - Where to use and avoid in Oil & Gas Offshore Industries? In offshore oil and gas operations, PTFE (Polytetrafluoroethylene) tape and sealants are not outright banned , but their use is highly regulated and often restricted depending on the application, pressure class, and safety requirements . Here's a breakdown of the considerations: ✅ When PTFE Tape/Sealants Are Allowed Low-pressure, non-critical systems : PTFE tape is commonly used for threaded joints in low-pressure hydraulic or pneumatic systems. Non-hydrocarbon services : Such as water or inert gas lines. Temporary installations : Where ease of disassembly is prioritized. ❌ When PTFE Tape/Sealants Are Restricted or Prohibited High-pressure systems PTFE tape can shred during installation, leading to blockages in valves or orifices , which is dangerous in high-pressure environments. Hydraulic and control systems Offshore platforms often prohibit PTFE tape in hydraulic control lines (e.g., fo...
