A cleaning process consists in shooting cleaning projectiles with compressed air through a hose and then sealing the ends of a complete hose assely with heat-shrink capsules. Cleaning the hydraulic hose asselies allows for obtaining hydraulic oil cleanliness class of 18/16/13 according to ISO 4406 standard (hydraulic oil cleanliness is determined on the basis of the nuer of particulate
Measuring hydraulic cleanliness is not straight forward, consequently various standards exist on this subject - see our page on Hydraulic Fluid Cleanliness for a review of the 2 most common. Share | The ISO Cleanliness Code, ISO 4406, 1987 is the perhaps the most widely used International standard however the dated NAS 1638 standard is still widely quoted by industries involved in UK North Sea.

Hydraulic systems demand the highest standards regarding the cleanliness of hose and pipe asselies. However, abrasion during the cutting and crimping of hoses causes the formation of chips or scales, which must not be present, as specified in ISO 4406 and NAS 1638. Therefore, in addition to its hose crimpers, UNIFLEX also offers special cleaning […]
