HUPLONG INDUSTRIES (M) SDN BHD is the authorized distributor of NORRES industrial hoses in Malaysia.

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES AIRDUC® PUR 356 EC (XHD) hose for high-throughput conveying and ducting of extremely abrasive bulk material, granulate and stone. NORRES officially lists this electrically conductive polyurethane hose for vacuum trucks, suction vehicles, dry suction trucks, industrial cleaning, furnace cleaning, silos, tankers and raw-material conveying applications.

NORRES AIRDUC® PUR 356 EC (XHD) is a super-heavy AIRDUC® profile hose. Its official construction includes a spring steel wire firmly embedded in the wall, an electrically conductive premium ester-polyurethane Pre-PUR® wall, an approximate wall thickness of 2.0 mm to 2.5 mm and reinforcement of the primary abrasion areas.

NORRES specifies this model as extremely abrasion-resistant with reinforcement underneath the wire and a narrow hose pitch. The hose also has good resistance to oil, gasoline and chemicals, together with very good low-temperature flexibility.

The electrically conductive wall has electrical and surface resistance below 10³ Ω. NORRES also references a value below 10⁶ Ω according to NFPA 652. The official operating temperature range is from -40°C to +90°C.

NORRES officially lists AIRDUC® PUR 356 EC (XHD) for coal mines, mines and tunnelling applications involving ventilation and methane extraction. Other listed uses include conveying powders, granulates, sand, quartz, gravel, shards and chips or shavings, as well as silo charging and silo discharging.

NORRES states that this model is in accordance with ATEX 2014/34/EU and German TRGS 727 for the specific flammable dust, bulk-material, flammable-liquid, non-flammable-liquid and gas-zone scenarios stated in the official product information. The complete system design, grounding arrangement and actual installation requirements must be assessed before use.

The permitted pressure, vacuum and bending radius values vary by hose size and must be checked against the official technical table before use.

Our team can assist customers throughout Malaysia with NORRES hose selection based on hose diameter, conveyed material, operating temperature, airflow, vacuum condition, installation length and quantity requirement.
