In-Line Sock Filters and Mesh Strainers NZ

HD Process supplies in-line sock filters for removing particulate matter from hygienic liquid process pipelines. These mesh filter elements mount within a Tri-clamp connection and provide a longer filtration surface than flat screen gaskets.

Filter Sizes and Materials

• Typical line sizes from 1" to 4".
• Standard filter lengths of 40 mm and 150 mm.
• Elastomer options normally include EPDM, nitrile and PTFE.
• Retention options from 2 mm down to 40 µm.
• Mesh ratings from approximately 10 to 325 mesh.

Inspection and Replacement

Sock filters should be inspected regularly for blockage and mesh damage. They use relatively lightweight filter material and may rupture if excessive differential pressure develops from accumulated solids.

Installation within an in-line sight glass can assist with visual inspection. These elements are best treated as consumables rather than permanent filtration screens.
