I’m Todd from BlastOne. Today we’re going to go over how to visually inspect your blast hoses to ensure they don’t have too much wear and that they’ll function properly on-site.
You can see on this hose, the aluminum coupling’s diameter matches the inside hose diameter, and the coupling doesn’t overhang. The gasket is also wearing out. The gasket is a wider diameter, and there’s no lip between the aluminum and the blast hose. On this one, there’s a small step where the aluminum coupling overhangs the blast hose, ensuring a proper seal around the lip.
If the aluminum coupling wears down and loses the lip, pinholes can form, allowing abrasive to escape between the gasket, aluminum coupling, and hose. You’ll see abrasive leaking from these spots.
Another issue is the separation between the hose and the aluminum coupling at the bottom, creating a weak point for abrasive to escape. Check that all eight screws in each aluminum coupling are seated tightly and haven’t punctured the hose. If screws puncture the hose, abrasive will force its way out through these holes.
Another sign of wear is the hose’s rigidity. When bending the hose, if it starts to give out on a gradual bend, it indicates the inside diameter is too worn and the hose should be replaced. Abrasive flow will wear down any part of the hose, especially at turns or pivot points.
Watch for hoses becoming more floppy, which indicates wear. This is how to visually inspect your hoses. If you have any more questions, click the link below and we’ll connect you to the right person.
