The Blast Hose is an integral part of any abrasive blasting system.

That is why high quality blast hoses should be selected and insisted on instead of poorly designed ones constructed with poor quality materials.

Cheap blast hoses which seem a good bargain at the time are easily available, but when the true quality begins to show, the reality is you have paid too much for an inferior product! If cheaper blast hose was made from recycled rubber, the probable life of the hose could be as meager as 150-200 hours. With a high quality blast hose, the expectant life is 400-500 hours depending on the abrasive used. You would be better off paying for a good quality, well constructed blast hose.

It’s not only quality, cost and how long it lasts – but will it protect you adequately from electric shock? The safety factor should come into the equation when making this important purchase.

BlastOne SupaLife blast hose is manufactured using virgin natural rubber with carbon black graphite. This has anti-static qualities to eliminate the problem by dissipating the static electricity through the wall of the blast hose.

BlastOne’s high quality SupaLife blast hose is constructed using a 2-ply or 4-ply arrangement – highly woven cord linings which are place in a cross ply pattern to add strength, but still allow the blast hose the flexibility that it requires.

Bull Hoses

Use a large internal diameter (ID) size. Running large ID lines (1.5” or 2”) from your compressor to your blast pot reduces the friction pressure
loss caused in smaller, more restrictive sizes. Air pressure drops have a large impact on production.

Blast Hoses

Make sure your blast hose is large enough to make the most of your nozzle. To get the highest, fastest production you need to run the largest
blast nozzle that your air source can support. It won’t do you much good to run a small blast hose to a large nozzle or vice versa.

WHIP HOSE (aka Supa, Supahose)

If an operator finds the standard blast hose too heavy to work with all day, a short length of flexible, lighter weight, blast hose – called a “whip”
– can be used near the nozzle. However, be careful of undersizing this hose. By decreasing the internal diameter (ID) you can increase friction
which slows the abrasive and air and decreases productivity.

Common Issues With Blast Hoses

The biggest issue that contractors face with blast hose is premature internal wear or external cracking causing the blast hose to fail and blow apart. This is a serious safety concern and blast hoses should be checked regularly to ensure they are safe. Any sign of ‘softness’ in the hose or visible external cracking, they should be replaced immediately.

Frequently Asked Questions

  • How Long Should Your Blast Hoses Be?

    Shorter is better!

    Keep you air hose and blast hose lengths short. Put your compressor as close to the blast pot as possible, and keep you pot near your blasters to shorten the distance the air has to travel and keep pressure drops to a minimum. It’s especially helpful to keep blast hose length short since pressure drops are even greater than in air hose because your pushing abrasive and compressed air through the line.

  • What makes a good blast hose?

    Blast hoses are make from compounds of rubber and carbon which is then wrapped around a long mandrill and oven cooked to set. it is the quality of the rubber compound that makes the difference. as blast hose manufacturers, you choose the quality rubber that you want to use in blast hose, typically there are 3 levels that apply to blast hoses measured by a DIN rating (which you can google elsewhere). BlastOne chooses to make our hoses out of the highest quality rubber, as they last longer, are more flexible and gives increased safety.

  • When Should I Replace My Blast Hose?

    1. When it is worn! You can test it by squeezing the hose with your hand, or stepping on it with your foot. If you are able to compress the hose, it is worn.
    2. A blast hose will give you some warning that it is preparing to blow. Often the outer liner will start to bubble, telling you that there is a pin prick hole. When you see this, the hose needs to be replaced immediately.

  • How Often Should I Replace My Blast Hose?

    It depends on the internal and external wear. Hoses can look beat up and still be perfectly safe to use. In a blastroom situation you can predict from failure analysis when a blast hose will need to be replaced.

  • How Can I Fix Premature Blast Hose Wear In A Blastroom?

    Blast hose often wears first within the initial 8ft of the hose. This is often where it has its first bend. This is common in blast rooms where the hose goes through the room wall, and bends inside the booth.

    It is best practice in a blast room, and a lot of field applications, to run a larger size hose, typically 2″, for the first 8ft-10ft, then couple down to a 1.5″ extension hose. This additional internal space in the hose will fix a lot of premature wear issues.
