PREMIUM Sandblast SM1 hose DN20 3/4" 15bar

The PREMIUM Sandblast SM1 DN20 3/4" sandblasting hose is a specialized conduit designed for transporting highly abrasive materials used in sandblasting, shot blasting, and abrasive blasting processes. The SM1 version stands out with its reinforced 4-layer textile construction, very high abrasion resistance of the inner layer, and antistatic design that limits the buildup of electrostatic charges during operation.

Standards: TS 5928 EN ISO 3861, EN ISO 3861, ISO 1307

SM1 variant for intensive work with abrasives

The SM1 series was developed for demanding applications where the hose is constantly exposed to contact with aggressive abrasive material. The manufacturer indicates use with, among others, quartz sand, steel shot, corundum, and glass.

Compared to lighter designs, SM1 uses four reinforcement layers, which improves the conduit's resistance to kinking and helps maintain stability during intensive operation.

Abrasion resistance 36 mm³

One of the key parameters of the Sandblast SM1 hose is the wear resistance of the inner layer. The average wear is 36 mm³ according to DIN ISO 4649:2021.

In practice, this means very high resistance to the action of abrasive materials flowing inside the conduit. This is directly significant for the durability of the hose and limiting the frequency of its replacement during intensive sandblasting.

Antistatic construction for sandblasting

During the flow of dry abrasive, electrostatic charges may build up. For this reason, the inner and outer layers of the SM1 hose have antistatic properties.

Such a construction limits the buildup of electrostatic charges during the transport of the abrasive medium and is an essential element of conduits intended for professional sandblasting.

Construction of the PREMIUM Sandblast SM1 hose

The inner layer is made of an NR/BR/SBR blend. It is smooth, black, abrasion-resistant, and electrically conductive. As a result, it is responsible for direct contact with the transported abrasive.

The reinforcement consists of four textile layers, while the outer SBR layer is resistant to ozone and atmospheric conditions.

DN20 3/4" for which installations?

The DN20 / 3/4" size is a popular variant in sandblasting installations requiring a good balance between abrasive flow and the convenience of handling the conduit.

When choosing, however, the entire system must be considered: compressor efficiency, nozzle type, conduit length, and required airflow. The hose diameter itself should not be selected in isolation from the other elements of the installation.

15 bar maximum working pressure

The variant offered at HYDRON is intended for operation at a maximum pressure of 15 bar. This value should not be exceeded during use.

A complete sandblasting kit should be evaluated as a whole. Couplings, clamps, nozzles, and other elements must also have parameters suitable for the working conditions.

Operating temperature from -35°C to +80°C

The SM1 hose can work in a wide temperature range from -35°C to +80°C. This allows it to be used both in cold outdoor conditions and in typical industrial applications.

Why is it worth checking the hose from the inside?

In sandblasting conduits, wear occurs primarily on the inner side. The outer surface may look correct even though the working layer has already been partially worn away by the abrasive.

Therefore, during periodic inspections, it is worth paying attention not only to external cracks and damage, but also to unusual softening, local deformations, or changes in cross-section.

SM1 vs SM2-how do these series differ?

SM1 is a more complex variant in terms of reinforcement construction. This family uses four textile layers and an inner layer with an average wear of 36 mm³, which predisposes it to intensive work.

SM2 is a more classic solution, also intended for sandblasting, but with a different construction and wear parameters. When choosing, one should therefore consider not only the diameter, but also the predicted intensity of use.

Typical applications

sandblasting of steel structures,
shot blasting of metal components,
cleaning surfaces of corrosion and coatings,
transport of quartz sand,
transport of steel shot,
transport of corundum,
transport of glass and other abrasive materials.

What to pay attention to during use?

do not exceed the maximum pressure of 12 bar,
avoid sharp kinks in the conduit,
regularly check the wear level,
check the condition of the outer rubber layer,
use properly selected couplings and clamps,
replace the conduit if damage affecting work safety is found.

Hose for professional sandblasting

PREMIUM Sandblast SM1 DN20 3/4" is a solution designed for users who need a conduit with high abrasion resistance and an extensive reinforcement construction. It works well in sandblasting workshops, industrial plants, and during field work.
