PREMIUM Sandblast SM2 DN32 1 1/4" 15 bar sandblasting hose

The PREMIUM Sandblast SM2 DN32 1 1/4" hose is a specialized conduit for transporting highly abrasive materials used during sandblasting and abrasive blasting processes. The DN32 variant has an internal diameter of 32 mm, an external diameter of 48 mm, and a maximum working pressure of 15 bar. The antistatic design and abrasion-resistant inner layer allow it to work with media such as quartz sand, steel shot, corundum, or glass.

DN32 for installations with higher flow

The DN32 size provides a large internal cross-section, which is why this variant is ideal for sandblasting installations requiring efficient transport of air and abrasive material over longer sections. The 1 1/4" diameter can be particularly beneficial for larger sandblasting equipment and industrial applications.

However, the choice of diameter should be linked to the compressor efficiency, nozzle diameter, hose length, and the required flow rate. A larger hose alone will not increase system performance if another element of the installation remains a bottleneck.

Abrasion-resistant inner layer

The most stressed part of a sandblasting hose is its internal surface. The abrasive stream acts on it throughout the entire operation, particularly intensely on bends and at points of direction change.

In the Sandblast SM2, the inner layer is made of an NR/BR/SBR mixture. It is black, smooth, antistatic, and abrasion-resistant. The average abrasion loss is 60 mm³ according to DIN ISO 4649:2021.

For transporting sand, shot, corundum, and glass

The datasheet indicates the use of the hose with highly abrasive materials such as quartz sand, steel shot, corundum, and glass. As a result, it can be used in sandblasting workshops, industrial plants, and during the cleaning of steel structures.

Antistatic hose design

The flow of dry abrasive material can cause the buildup of electrostatic charges. For this reason, the Sandblast SM2 has an antistatic construction that limits their accumulation during operation.

The antistatic properties apply to both the inner and outer layers, which is crucial when using the conduit in sandblasting processes.

Construction of the PREMIUM Sandblast SM2 DN32 hose

The inner layer is made of an NR/BR/SBR blend. The reinforcement consists of two textile layers that stabilize the conduit's structure during operation.

The outer layer made of SBR is black, antistatic, and resistant to ozone and weather conditions. The surface has a characteristic fabric impression.

15 bar and safety factor 3.5:1

The maximum working pressure for the DN32 variant is 15 bar. The safety factor specified in the documentation is 3.5:1.

These parameters refer to the hose itself. A complete sandblasting kit should be evaluated as a whole, so couplings, clamps, and other components must also be selected for the required operating pressure.

Bending radius 320 mm

The minimum bending radius for the Sandblast SM2 DN32 is 320 mm. For such a large conduit, this parameter is particularly important for the correct layout of the installation.

Bending it too tightly can lead to cross-section deformation, flow restriction, and localized increase in internal wall wear. The hose should also not be kinked directly at the coupling.

External diameter 48 mm and coupling selection

When selecting fittings, clamps, and accessories, one must consider not only the nominal diameter of 1 1/4" but also the actual external diameter of the hose, which is 48 mm.

This is especially important in systems where the mounting method depends on the external diameter or wall thickness of the conduit.

SM2 DN32 and operational intensity

The SM2 is a classic sandblasting hose with very good internal layer wear resistance. The construction with two textile layers ensures hose stability while maintaining the flexibility needed during work.

For very intensive applications, it is worth comparing different series not only in terms of the number of layers but also abrasion resistance, diameter, bending radius, and the parameters of the entire installation.

Operating temperature range

The hose can operate in temperatures from -35°C up to +80°C. This range allows it to be used both for outdoor work and in typical industrial conditions.

Wear control during operation

Sandblasting hoses wear out mainly from the inside, so a good condition of the outer layer does not always mean the conduit has retained its full wall thickness.

The manufacturer recommends regular inspection of the conduit and its replacement in case of damage to the outer layer or the appearance of unusual signs of wear.

What to check before purchasing?

whether the required size is DN32 / 1 1/4",
whether the installation pressure does not exceed 15 bar,
whether it is possible to maintain a minimum bending radius of 320 mm,
whether the couplings fit the external diameter of 48 mm,
whether the compressor efficiency corresponds to the diameter of the hose and nozzle,
whether the conduit will be used with materials intended for transport in sandblasting hoses.

For professional sandblasting installations

The PREMIUM Sandblast SM2 DN32 1 1/4" is a good choice for sandblasting workshops, industrial plants, and field work where a large conduit cross-section, abrasion resistance, and stable operation with abrasive material are required.
