How It's Done – Hose Assembly Inspection
Hose assemblies are produced one at a time, and with each new assembly comes the possibility that the components have been put together in a slightly different way than the previous assembly. These differences will have virtually no bearing on the hose assembly's performance, but because each one is custom made, they are often all inspected.
A hose assembly order can consist of one hose assembly or one hundred. But even a single hose assembly must meet a number of specifications such as:
- Hose size (I.D. x O.D.) and length
- Fitting size and style
- Collar size
- Overall hose assembly length
- Proper fitting and collar attachment
- Appropriate pressure or vacuum capabilities
In addition to transferring liquids, some assemblies are also intended for static grounding, meaning that a metal wire (typically stainless steel) within the hose's layers must stay in contact with a metal crimped-on collar. Improper grounding could have disastrous results.
Quality inspectors may examine all hose assemblies in a customer's order or a predetermined sampling, such as every fifth hose in an order of fifty. When an order contains multiple assemblies, inspectors look for consistency between assemblies in addition to the individual specifications.
Because NewAge Industries makes hose assemblies for industrial uses (waste fluid discharge, pneumatic operations and petroleum product feeds, for example) and for clean applications through our AdvantaPure® high purity products division (pharmaceutical processing, pure water transfer, food conveyance), the company's inspectors are trained in the specific requirements of different industries. For instance, when an inspector examines hose assemblies for use in clean applications (like biopharmaceutical product transfer), they must consider items such as gamma irradiation requirements, certifications and proper double bagging and packaging. Conversely, when an inspector examines hose assemblies for industrial uses, they need to "turn off" those clean application aspects.
