Me high pressure fuel pipe safties.

High pressure fuel pipes is drown with a rigid protection (jacketed pipe), which is practically a second pipe, even if it’s thicker than the one inside, and it replaces the flexible girdle. the space
between the inner and the external pipe must never interrupt, in order to allow flowing of the leakages.The leakages will be of very low pressure and a method for detection must be provided.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
