FluoroLine PFA tubing pressure ratings were established using ASTM D2837. This test exposes the tubing to long-term, constant pressures at various temperature settings. Our test took 22 months to complete. From the analysis, a hydrostatic design basis (HDB) value is multiplied by a safety design factor to obtain a hydrostatic design stress. The HDB value is used to determine the tubing operating parameters. FluoroLine PFA tubing completed this extensive testing.
All FluoroLine tubing products are fully characterized and all performance ratings are derived from quantifiable data. Our design and process expertise allow you to confidently design your fluid systems reliably and safely.
