Common Failures and Solutions for Sealing Rings in Oil Extraction Equipment

Sealing rings in oil extraction equipment often fail due to aging, chemical corrosion, or improper installation, leading to leaks or system malfunctions.

Common issues include: Hardening/cracking from high-temperature exposure—replace with heat-resistant materials like HNBR or FKM.

Swelling/degradation caused by chemical attack—select chemically inert options such as PTFE or Viton.
Extrusion damage under high pressure—use backup rings or reinforced designs.

Regular inspection, proper lubrication, and adherence to pressure/temperature limits are critical to prolonging service life.
