Do you know when your blast hose needs replacing?

Do you know the visual and physical signs of wear that will indicate when your blast hose needs to be replaced?

What are the signs of wear?

Integrity of the hose wall

The integrity of the hose wall is an important aspect of blast hose safety. It is essential to check the internal wall of the hose as this carries the high speed abrasive.

A sign that the internal wall of the hose has been worn away and the hose is getting towards the end of it's life, can be identified if depression (squeezing) of the hose is easy. The hose should be checked about every 20cm along the length hose.

Blasting radius

If an operator has been blasting with the hose bent at a severe radius (eg, over their shoulder) the hose can wear prematurely in that area. This is extremely unsafe as the wear point is close to the operator.

To prevent this, operators should maintain a wide radius of the blast hose when blasting. This includes the whole length of hose from the blast pot right up to the operator.

Visual damage

Check the blast hose for holes, cracks, splits or any other erosion on the outer wall.

Safety tip

Cutting the hose

When a hose has been cut to attach a fitting, always make sure that it is cut evenly and neat so that when the hose is pushed into the fitting, it goes all the way to the ferrule in the back of the fitting.

Inserting screws to the hose

When inserting screws to the hose, ensure that they do not penetrate the hose wall. This can cause the abrasive to come up through the hole of the screw. The screws are to secure the fitting to the hose, but also require a secondary adhesive for a secure connection.
