Sandblasting hose is used to convey abrasive materials at high pressure to clean surfaces. This hose is safe and durable and comes in many sizes and configurations.
Unisource’s wear-resistant sandblasting hose is constructed from an extra thick tube of abrasion resistant rubber, textile plies for pressure reinforcement, and a weather and abrasion-resistant cover.

Sandblasting is a process to remove dirt, debris, paint, and other surface contaminants. It is used in a variety of industries and applications including industrial manufacturing, oil/gas, and ship refurbishment. This procedure can improve material properties, part performance, and labor efficiency while reducing environmental impact.
Depending on the blasting media and abrasive used, it can reduce or eliminate corrosion. Some abrasive, such as soda or sodium bicarbonate, can leave a protective film on the surface after blasting, which enhances corrosion resistance and extends the life of the material.
Blasting can also increase fatigue strength and the longevity of machined parts, such as dies, molds and drills, as well as the life expectancy of saw blades, end mills and drills. Blasting also allows for the removal of embedded debris from cutting edges and between teeth.
This type of abrasive blasting uses an abrasive tool with high-carbon steel wire bristles. They are dynamically tuned to contact and dislodge contaminants. This process is less destructive than other abrasive finishing techniques, such as grinding wheels and rotary files.
A wear-resistant sandblasting hose is designed to withstand the abrasive and vibration of blast cleaning media. These hoses are constructed of an extra thick, extremely abrasion resistant tube that extends the life of the hose. Operator fatigue is further reduced by its flexible and kink-resistant design.
precautions for installation of wear-resistant sandblasting hose
Abrasive blasting is an extremely effective method for cleaning and stripping metals. It can remove rust, oxide scale, corrosion grease, dirt, coatings, sealants, carbon deposits and varnish.
It is also excellent for removing mill scale, welding tarnish and oxidation. Compared to other abrasive media, such as discs, flap wheels or wire wheels, it has superior capabilities in removing surface contaminants from areas that are not easily accessible by other methods.
Sandblasting requires the use of protective gear. This includes gloves, clothing, safety footwear, earplugs and OSHA-recommended respiratory equipment.
Sandblasting hoses are an integral part of blasting systems and must be maintained in a safe and efficient manner. It is important to inspect the hose and its fittings for any leaks, soft spots or holes, as well as general wear and tear.
To ensure the best performance, the hose application range is large. It is recommended that each hose be checked before each shift. In addition, check the nozzles for bore wear and damage. Bore wear and damage can decrease the effectiveness of the sandblasting process by increasing the demand for air and thereby reducing the abrasive’s exit velocity. It can also lead to excessive working pressure or kinking of hoses, which eventually will cause them to fail.
Media transported using wear-resistant blasting tubes
Blasting equipment and its parts must withstand extreme pressure, abrasion, vibration. It is important to choose a hose that will not only resist external abuse, but also internal abrasion.
It doesn’t matter if it is a water blasting hose, sandblasting or blast cleaning hose; its abrasion resistance will determine its durability and longevity. The best hoses are made with reinforced layers of cord thread or fabric. This improves the hose’s strength and flexibility.
A blast hose can transport a variety of abrasive media such as sand and steel shot, ceramic beads and abrasive sponge media. Aluminum oxide is the most commonly used blast abrasive in industrial applications. However, there are other types of abrasives.
The appropriate blasting equipment selection will depend on the type of media used for that particular end-use (cleaning and peening, etching. deburring. stripping. surface engineering / residual stresses). For example, aggressive coarse grit is best for bonding thermal spray deposits, high build coatings, and polymeric lining systems. For thinner coatings, paint, or other finishes, a slower profile etching, cleaning or stripping is necessary.
Consider the blasting equipment’s annual operating, maintenance, and consumable costs when evaluating the cost-effectiveness of a blast hose. Choosing an efficient, durable, and long-lasting blasting hose will reduce the system’s total cost of ownership.
