Does the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) require reduced working pressure above +80Â°C, and how is it calculated?

Yes. For the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) the maximum working pressure must be reduced for temperatures above +80Â°C. The reduction is 5% of the working pressure for each 1Â°C above +80Â°C. Calculation method: Reduced pressure = nominal working pressure Ã (1 â 0.05 Ã (T â 80Â°C)) Example (given): for AF-VFPB-19 with nominal 16 bar at T = 90Â°C: Reduction = (90â80) Ã 5% = 50% â Reduced pressure = 16 bar Ã (1 â 0.50) = 8 bar. Notes: - Operating temperature range: â30Â°C to +100Â°C; resistant to full vacuum up to +80Â°C. - Working pressure values depend on hose diameter (12.5â30 bar nominal).

How does the antistatic version of the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) achieve electrical dissipation?

The antistatic version of the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) achieves electrical dissipation by using PTFE (Teflon) with evenly distributed carbon additives in the inner corrugated layer. This modified PTFE (version AS) yields a bulk resistance R < 10^8 Î© (per ISO 8031 annex A), allowing accumulated electric charges to be conducted away and dispersed, preventing charge buildup. The hose retains the same polypropylene braid reinforcement and operating characteristics, while the carbon-filled PTFE provides the antistatic path.

Can the PBB (black) version of the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) be used in the same chemical environments as the standard PB?

Yes. the PBB (black polymer braid) version of the Teflon hose in polypropylene braid HYPERLINE V (VISIFLON) can be used in the same chemical environments as the standard PB braid. The product description states the black braid option has similar characteristics to the standard PB and is offered for applications where bright colors are not acceptable. Core construction (spiral corrugated PTFE) and polypropylene braid chemistry remain the same, so chemical resistance is equivalent. Note operational limits and special cases: temperature range â30Â°C to +100Â°C, vacuum resistance up to +80Â°C, and reduction of maximum working pressure above +80Â°C (reduce by 5% per Â°C). If antistatic properties are required, choose the AS version (carbon-loaded PTFE, R < 10^8 Î©) rather than PBB.
