Sandblasting hoses are one of the key elements in any blast system, and selecting an effective one can significantly boost productivity.Blast hoses come in varying ply constructions; the higher its ply count, the more durable its construction. Ply thickness also impacts its resistance to wear caused by materials on site or dragging, as well as to being easily compressed when not in use.
Tube
A sandblast hose is one of the cornerstones of any abrasive blasting system, as it allows blast media to be delivered under pressure directly to surfaces being cleaned or prepped. The quality of this component directly impacts efficiency, safety and results of any sandblasting operation.
Sandblasting hoses are specially constructed to withstand the wear and tear that is associated with abrasive blasting, typically comprising rubber and high tensile strength fabric materials. Furthermore, their tubes offer protection from chemicals as well as weather elements – making them suitable for industrial uses.
Parker’s Series 7244 Sandblast Hose was engineered to deliver heavy duty service across a range of medium pressure blasting and transfer applications, from medium blasting pressures up to 250 PSI. Featuring a thick rubber tube with advanced resistance to abrasion and the capacity to manage high pressures, its cover material consists of black smooth, nonconductive NR blend abrasion resistant material that features static dissipating properties to ensure operator safety.
For effective abrasive blasting operations, we advise using a hose with an inside diameter that is three times greater than that of your nozzle orifice size. This will extend its lifespan while maintaining adequate pressure at your nozzle.
Sandblast hoses must not only be resistant to abrasion but also flexible enough to withstand kinking. We offer an assortment of lengths and sizes so you can find the ideal sandblasting hose for your application.
No matter which abrasive blasting hose you choose, it is vital to inspect it regularly for signs of wear and tear. If any cracks or cuts occur in the tube, replace immediately; also look out for leaks or air bubbles which could compromise its integrity, replacing as soon as possible in order to protect your investment and maximize performance with your abrasive blasting equipment. This will safeguard its integrity as well as maximize return from its usage.
Cover
Sandblasting hoses are specially designed to facilitate the high-velocity transfer of abrasive materials such as steel shot, sand and grit for cleaning metal parts, stones and glass surfaces, derusting concrete slabs like bridges and tunnels, conditioning strip cement in industrial applications like bridges and tunnels and cleaning agricultural machinery such as tractors or farm equipment.
These hoses feature a black smooth, conductive NR blend cover that is abrasion resistant and static dissipating. With heavy duty 4-ply construction and rated to work at 290 psi working pressure, they can withstand light vehicle traffic without collapsing, as well as general wear and tear in your blast facility. Plus they accept industry standard couplings and nozzle holders!
Blast hoses should be chosen carefully to reduce unnecessary wear and maintain optimal air pressure in your blast system. Hoses that are too small may quickly wear out while those that are too big may lose pressure along the middle – Blue Dog advises selecting a hose which is three or four times larger than your nozzle’s inside diameter for best results.
Sandblast hoses come in many different lengths to suit every project. When selecting the ideal length for you, take into account factors like proximity to your work site and whether or not you will use other equipment, like a blast gun. Maintaining your hoses away from vehicle traffic, chemicals and sharp edges is key to prolonging their lifespan. When possible, try keeping them straight while making gradual bends for optimal performance. If you need to run hoses up scaffolding or other structures, make sure they are secured with safety cables to avoid their weight ripping apart the couplings. Hoses exposed to the elements should also be regularly checked for signs of wear and tear; any signs such as cuts, punctures or abrasions must be repaired immediately as these can penetrate to cause internal damage to a hose and require immediate repair work.
Ply
A sandblasting hose is used to transport abrasive materials like sand, grit and shot during the blasting process. As this heavy-duty hose must withstand high pressure and the materials it transports, durability is of the utmost importance as well as flexibility to withstand repeated use without kinking. Inner tubes typically consist of abrasion-resistant rubber while outer layers typically boast weatherproof covers for protection from weather elements and buildup of static electricity build-up.
2 ply sandblasting hoses are ideal for light to moderate abrasive-blasting jobs and typically lighter than 4-ply ones. Withstanding considerable pressure, 2-ply hoses can easily work with all common blast media while being easy to maneuver for faster work efficiency. 2-ply hoses also make great “whip hoses,” the final 10-15 feet that connect your blast gun or cabinet directly.
This thicker and sturdier 4-ply sandblasting hose was specifically created for industrial environments in which external abrasion is likely. Perfect for blasting on ships, railyards or facilities where it will be dragged around by light vehicles without collapsing, it has two liners: four layers of natural rubber abrasive-resistant natural rubber as well as high-tensile textile cord reinforced liners to withstand external abrasion.
An efficient sandblasting process relies on having access to quality blast hose. This enables operators to control how much media is blasted while maintaining consistent pressure throughout its length. Furthermore, making sure you purchase one suited for your application helps prevent overly pressurized or restricted media flow.
excellent sandblast hose comes equipped with a 150 psi working pressure rating and can accommodate a variety of blast media types. Temperature range for use: -40 to 180 degree Fahrenheit and burst ratio is 3:11:00, meaning this durable hose can handle even harsh environments with ease. Furthermore, its thick wall construction means it’s designed to withstand high-pressure applications without fail.
Safety
The blast hose is an integral component of any sandblasting machine, providing fast delivery of high-pressure air to the blast nozzle. However, improper maintenance and misuse can result in dangerous accidents which cause serious injury or death; for this reason it is vital that workers in blasting areas wear PPE while working with this hose and adhere to safety protocols when doing so.
Blast hoses are usually constructed of sturdy and resilient materials capable of withstanding the forces and abrasion associated with sandblasting. Regular tests should be conducted on these hoses to ensure they meet all required parameters for their intended application, and ensure proper storage, handling and disposal to mitigate potential risks.
Sandblasting hoses typically consist of an inner tube and outer casing crafted from durable material such as SBR rubber treated with static-dissipating agents, while their outer casing may feature black heavy duty synthetic rubber that has been pinpricked to prevent air pockets forming in between them.
Sandblast hose service life depends heavily on operating conditions, hours of use and type of media being transported. Therefore, it is crucial that they be checked regularly and replaced as needed to ensure safe functioning.
Proper maintenance involves more than simply changing out sandblasting hoses; it requires also making sure that the entire blasting area is safe from potential hazards, including containment structures for any potentially hazardous materials that might escape into the environment. Regularly checking hose couplings and whip checks to make sure that they remain undamaged is also key to effective performance.
Maintaining an adequate ventilation system in the blasting area is also necessary, since the use of sandblasting equipment produces large quantities of dust which could be dangerous if inhaled. Workers should wear heavy-duty gloves to protect their hands from abrasion and full face respirators for additional protection from inhaling toxic dust particles and airborne particles.
Proper electrical grounding is key to avoiding static electricity build-up that could spark and ignite dry abrasive particles, as well as extinguish all open flames or smoke near the blasting area. Furthermore, it should be noted that any modifications or gerry-rigging of equipment could compromise both its safety and performance.
