When searching for a blast hose there are certainly a number of brands out there, however when it is quality and durability you are after, Clemco is the number one choice of all. Clemco uses only the best materials in their hoses, ensuring that you get all that you need in the product that you have purchased.
The rubber inside of your hose can quickly become worn, thanks to the friction against the flow, very similar to what car tires would produce. With Clemco you get high-quality rubber that resists abrasion but it doesn't stop there, as Clemco hoses use reinforced piles of braided strands and a tough outer casing to provide the reliability you are after.
Designed with reinforcing plies that withstand pressure and hold the shape of the hose, the outer casing protects the lies from abrasions and cuts allowing the hoses to stand up to the pressures that they undergo every day.
Along with ensuring that you are purchasing one of the best brands of hoses that are out there, you can also take steps to ensure that you make the life of your hose last much longer. This is easily done with regular inspections of the hose and its couplings. During these inspections you should check for things such as cracks, holes or disintegration of the hose. If damage is discovered it is time to replace the hoses.
Although it may be tempting, do not use tape or similar materials between the couplings. This can cause it to blow off when under pressure, causing serious injury to anyone who is in the way. Screws that do not fit are also a possible cause of injury, causing leaks and wear on the hose. This is possible for screws that are either too long or too short. To ensure the screws get a good grip, insert a dowel for support to the hose as you tighten the screws.
If couplings look cracked or otherwise worn, they should be replaced as quickly as possible. The nozzle holder should also be replaced if the threads begin to show wear. If it is discovered that the couplings and hoses are in good condition you can keep using them as you would.
Hoses should lie in a straight line, facing away from the vehicle traffic as well as chemicals and sharp edges. Ensure that the bends gradual as sharp turns will cause rapid wear; this is the number one cause of hose wear. An experienced contractor will use a short length of flexible whip hose for the last few feet before the nozzle and discard this whip hose when it wears.
In addition you should use a blast hose that is at least 3 to 4 times the ID of the nozzle. This helps control the rate of flow through the hose and ensures that you aren't using a hose that is too close to the nozzle and reducing the amount of wear the hose will sustain. If the hoses run up scaffolding or structures, secure them every 20 feet and install safety cables to keep the weight of the hose from pulling apart couplings.
Once blasting has occurred you should close the metering valve and blow air through the hose to remove any remaining abrasive. Moisture and abrasive that is left inside of the hose through the night may collect in clumps, and those clumps can cause restrictions that increase wear the wear and tear of your hose. It is recommended that the coil be gently pulled to prevent kinks. It also enables a clean, dry area away free of oil, chemicals, and paint. A blast hoses should never be placed on racks for prolonged periods as this can cause kinks and worn spots on the outer casing.
While these steps will ensure that your hose needs replacing less often, it is inevitable that replacement will not be necessary at one point or another. Even taking the required precautions, your blast hose will wear out and eventually need replaced, and when it does, you should ensure that you are using only a high quality replacement hose.
