PART NUMBER ANALYSIS

To properly select or replace this material

Composition and Mechanical Properties

SF 5000 is a non-asbestos sheet composed of carbon and aramid fibres bonded with NBR. The presence of carbon should not be confused with an expanded graphite gasket. The specification table indicates 440°C and 140 bar as distinct maximum limits, with 7.5% compressibility and 64% recovery. A catalogue density of 1.6 g/cm³ situates this material within the standard compressed fibre sheet range.

Sheet Applications

The manufacturer specifies this grade notably for caustic liquors and other concentrated alkalis, subject to chemical compatibility and operating temperatures. Gasket thickness and bolt loading must be evaluated under actual service conditions.

Material Selection and Replacement

For alkaline liquor service, verify the concentration, continuous operating temperature, cleaning cycles, and flange specifications. Compare with an alternative carbon/NBR sheet only after thorough chemical validation. The specified maximum pressures and temperatures are not inherently cumulative, particularly during severe thermal cycling.
