Petrochemical Applications

Oil drilling is very demanding because seals have to work under extreme conditions. If a seal fails, the resulting repairs and production stoppages are very costly.

Seals in drilling equipment can be exposed to harsh chemicals and gases — different hydrocarbons (including sulfonated ones), superheated steam, hydrogen sulfide (H₂S), carbon dioxide, methane, and amine-based corrosion inhibitors — plus very low or very high temperatures (below 0°C up to over 200°C) and high pressures.

To cope with so aggressive and diversified combinations the following features must be granted at the same time:

  • chemical resistance
  • outstanding physical properties
  • elasticity in a wide range of temperatures
  • resistance against explosive decompression (AED)

We have many years of experience fixing tough sealing problems in the Oil & Gas industry.

We’ve successfully provided sealing solutions for equipment such as:

  • Ball valves, gate valves, butterfly valves, regulating valves, plug valves, seat valves, check valves, metering valves, control valves

  • Valve actuators, blowout preventers (BOP), couplings for flexible pipes

  • Xmas trees, drill drives, marine cranes

anyseals offers a wide range of O-rings, rubber gaskets, and standard PTFE seals in sizes up to Ø 2300 mm (≈ 90 inches).
