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).

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.

Teflon hose in polypropylene braid HYPERLINE V (VISIFLON)

Q: 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.

The HYPERLINE V (VISIFLON) hose features an inner layer made of high-quality corrugated PTFE, providing exceptional flexibility and vibration resistance. It has a polypropylene fiber braid characterized by low weight and high chemical resistance. At operating temperatures above +80°C, the maximum working pressure should be reduced by 5% for each 1°C increase in temperature. For example, at a temperature of 90ºC, the maximum working pressure for the hose AF-VFPB-19 is: 16 bar – (90°C-80°C) x 5 = 16 bar – 50% = 8 bar. There is an option to order a version with a black polymer braid (version PBB), with similar characteristics to version PB, for applications where bright colors cannot be used. Available versions: standard (orange) and antistatic (black). The antistatic Teflon of version AS contains evenly distributed carbon in the PTFE and has a resistance R <10⁸ Ω (according to ISO 8031 annex A). This ensures the dissipation and dispersion of electric charges. Hose material: spiral corrugated PTFE (Teflon). Reinforcement: polypropylene braid. Working pressure: from 12.5 bar to 30 bar – depending on the hose diameter. Operating temperature: from -30°C to +100°C. Resistant to full vacuum up to a temperature of: +80°C.
