What is rubber sandblast hose

The inside of the sandblasting hose is made of natural rubber, which has a considerable resistance to abrasion. The outer layer is made of a polymeric material. There is reinforcement, which acts as a double textile braid.
From sandblasting to choose the right hose is directly dependent on the speed and quality of sandblasting and abrasive consumption.
The standard length of the blast hose: - 20 and 40 meters.
1. The sleeve fits (steel shot, silica sand, glass, corundum, kupershlak, grenades and so forth. Can be used) for sandblasting
2. Antistatic internal layer protects from the appearance of electrostatic discharge
3. The inner layer is made of natural rubber with high resistance to abrasion
4. Working pressure: 12 bar
5. Burst pressure: 36 bar
6. Sleeve working loads at different temperatures from -35 to +80 degrees
Wear abrasive blasting sleeve inside leads to the loss of pressure during transport of air-abrasive mixture, as a consequence of reduced cleaning rate and increased consumption of abrasive material. Therefore, the savings on sandblasting hose price may be questionable and lead to higher costs in the production of sandblasting work.
Sandblasting (abrasive) sleeve has a high resistance to abrasive particles. Used in systems and plants and sand blasting different surfaces and parts. With these sleeves, by means of compressed air supply is made of steel shot, quartz sand, corundum and other materials used for cleaning. Sandblasting sleeve widely used in the construction industry for supplying different solutions (cement, gypsum, etc.), as well as concrete mixtures using concrete pumps. Products at work do not accumulate static electricity, which ensures their safe use. The use of wear-resistant materials for the production of hoses for long life of their operation, and to enhance the strength of reinforcement is carried out using a tissue winding. All products meet international standards system DIN ISO 4649: 2006. Allowed to operate at temperatures from -35 o C to +80 o C.
With sand-blasting method can achieve varying degrees of purification. When cleaning, can be divided into metal surfaces purity 4 following groups:
1. Sandblasting effect reminiscent of cleaning with a wire brush.
Routine cleaning of surfaces without a mirror shine effect.
Clean metal surface almost to perfection.
2. Clean the surface of the metal to full brightness.
The choice of treatment should be determined in advance depending on which coating was applied to the metal surface: corrosion, enamel, primer, zinc or plastic coating, etc.
• Blasting hose is designed for supply of abrasive materials and is used in jet engines and installations blast cleaning surfaces with structures serving quartz sand, steel shot, sliced, corundum, nikelshlaka, kupershlak etc;
• very high life expectancy abrasion resistant inner layer. In the production of sandblasting hose is used only high-abrasion rubber that allows to obtain high-quality sandblasting hose with a lifetime of about 3-5 times higher than that of many Chinese and Russian counterparts sandblasting hose;
As practice shows, from how sandblasting sleeve is always directly dependent on the quality of the device is selected correctly, jet speed, abrasive consumption. It is very important to consider that this structural element is always exposed to increased wear and require particularly careful choice in quality and durability.
In order to determine the condition of the hose it is recommended to periodically use a special gauge. If the pressure in it is reduced at 1 atm., Recommended replacement. Quickly wear out the air hose does not allow the installation to fully operate. This leads to a loss of pressure reduction purification rate of volume increase sacrificial abrasive. As a result, savings in the cost of the hose leads to a significant increase in operating costs.
In order to determine the diameter of the blasting hose is sufficient to multiply the inner diameter of the nozzle at the 3. Select hose with a margin on the length are not recommended, as it will lead to the senseless loss of pressure.
Before starting work, always check the outlet pressure. If you have recorded a loss of pressure even by 1 bar compared with a new hose, replace it. Failure to replace the blast hose can rupture the hose, that is unsafe.
When purchasing a sandblasting hose, you have to understand that it is not necessary to save, because here it is necessary to use a hose with an inner diameter as large as possible. The pipeline for the air supply may not be large enough. The larger internal diameter of the blasting hose, the less friction loss.
In order to choose the right sandblasting sleeve, determine the diameter of a blast nozzle you want to use. For correct operation, the hose diameter should be 4 times higher. Buy sandblasting sleeve is only required length, unjustified increase in length will lead to pressure loss.
Generally, not all of the same sleeve sandblasting quality. Choosing a quality sleeve for sandblasting, you will provide a continuous speed, the quality of treatment and reduce the consumption of abrasive material transmitted through the hose.
