PTFE IMPREGNATED WIRE MESH FOR SUPERIOR ANTI-EXTRUSION

Patented Sintermesh® material was specifically designed for oilfield applications where downhole packers are deployed to seal an annular space between pipes and liners with often large extrusion gaps. This concept, however, can be used in a variety of industries where large anti-extrusion devices are needed. It is an anti-extrusion ring made by compressing wire mesh into the desired density. This wire mesh can be impregnated with a variety of compounds depending on the requirements of the application to further prevent the migration of seal material through the porosity of the mesh at very high pressures. Sintermesh rings can be made of separate components in a packer assembly, or they can be molded into elastomeric components to create unitized anti-extrusion packers.

Service applications include:

  •  -300°F to +650°F
  • High-pressure
  • Large extrusion gaps
