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.

Our Blast Hose Manufacturing Process

Today we’re going to explain to you the blast hose manufacturing process.

It all starts right here in the Banbury. This is the Banbury that mixes all 13 ingredients that makes up the rubber compound that blast hose is made out of.

Here at BlastOne we specify that we have the highest quality materials and buy from the best vendors. This is one of the key parts that separates the BlastOne blast hose from other competitors.

What comes out of the Banbury is rubber sheets. Once the rubber sheets come out of the Banbury, it’s very important that we batch them, and every single batch we take a sample of that rubber sheet and we send it to
the lab.

There’s two main tests needed. Test with the briometer, you test the properties of  that rubber puck that’s come off that sheet. Then we also do a test on abrasion resistance. First of all, you weigh the sample then you put it in the abrader and you send it 40 meters on that 60 grit sandpaper… and then you measure the weight of it after the abrasion test has been done. And you measure that in cubic millimeters of abrasion lost. So how much has been lost in that test and all of our blast hose is manufactured to a standard of… to be no more than 50 cubic mm (1.95in). Some blast hoses are made to 70 or even 100. That’s because they use lower quality products and don’t have the manufacturing process to ensure that you can always have a consistent product.

Here we are in the Calendar. You can see we have the palette of sheets here that we’re putting into the calendar to mix it one more time so it mixes it all together to make it more homogeneous and to make sure that we have a very consistent material. And we cover in a small dusting of zinc stearate to roll it out without it sticking together and causing its inconsistencies. And it’s very critical that we have to maintain tolerances to ensure that we get our high quality blast hose.

So here we have the Textile Calendar. This is where we’re putting the fly cord (textile fabric) and meshing it together with the rubber. This is the reinforced fabric that gives the pressure rating to each hose… so it gets embedded in the rubber so that we can then put that out onto the mandrel.

All blast hose is made on a Mandrel. So you have the mandrel which is a certain thickness that you want the inner diameter of the blast hose, and put them on the mandrel carriage and the carriage goes up and down putting the exact amount of rubber. One of the important parts of blast hose manufacturing process is that you add a copper wire so that it’s static dissipating. Now that we’ve done the copper wire we’re putting another layer of the textile fabric on and this is, this is very very strong, very pressure resistant and then you put on some more rubber on the outside, and the last thing you do before you put it in the vulcanizer is you wrap it in a wrapping tape which helps keep it compressed and make sure that it all vulcanizes and combines together homogeneously.

So here we are at the Vulkanizer. This is where we knot together all that products on the mandrel. We put it in there at 150 degrees Celsius (302 F) at 60 PSI and it goes in there for 70 minutes and that gives it enough time to melt together, homogenize together, and then you pull it out let it cool down and then we go take it off the mandrel. After we have come out of the vulcanator let me pull it out and we roll it up.

Welcome to the blast hose manufacturing process.

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.
