Can the PUSH-IN polyamide hose for lubricating products TB 66 be used continuously at +60Â°C, and how should its maximum working pressure be adjusted using the correction factor?

Yes. The PUSH-IN polyamide hose for lubricating products TB 66 can be used continuously at +60Â°C, because its operating temperature range is 0Â°C to +100Â°C. However, its maximum working pressure must be reduced using the correction factor for +60Â°C, which is 0.58. To obtain the allowable working pressure at +60Â°C, multiply the hoseâs rated maximum working pressure at +20Â°C by 0.58 (i.e., corrected pressure = rated pressure Ã 0.58).

Can the PUSH-IN polyamide hose for lubricating products TB 66 safely operate at +80Â°C, and how does the correction factor change its maximum working pressure?

Yes - the PUSH-IN polyamide hose for lubricating products TB 66 can operate at +80Â°C (its material and spec allow 0Â°C to +100Â°C). However, its maximum working pressure must be reduced by the correction factor for +80Â°C, which is 0.47. That means the allowable working pressure at +80Â°C = nominal maximum working pressure Ã 0.47.

Is the PUSH-IN polyamide hose for lubricating products TB 66 rated for intermittent use at +100Â°C and how is pressure corrected?

The PUSH-IN polyamide hose for lubricating products TB 66 Format is specified with an operating temperature range from 0Â°C to +100Â°C, so it is rated for use up to +100Â°C. However, for operating temperatures above +20Â°C the maximum working pressure must be reduced using the given correction factors. To correct pressure, multiply the nominal maximum working pressure (specified at +20Â°C) by the factor corresponding to the actual operating temperature: - +20Â°C â factor 1.00 - +30Â°C â factor 0.83 - +40Â°C â factor 0.72 - +50Â°C â factor 0.64 - +60Â°C â factor 0.58 - +70Â°C â factor 0.52 - +80Â°C â factor 0.47 Example: if the hoseâs max working pressure at +20Â°C is Pmax, at +100Â°C the product is still within the stated operating range but no correction factor is provided above +80Â°C in the data; therefore you must not extrapolate beyond +80Â°C using the given table. For temperatures between listed points interpolate conservatively or consult the manufacturer.
