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 351 EC (MD) hose for flexible ducting of abrasive powder, bulk material, granulate and gases. NORRES officially lists this electrically conductive polyurethane hose for industrial vacuum cleaners, vacuum cleaners, explosion hazard area applications, coal mines, mining and tunnelling ventilation, and methane extraction.
NORRES AIRDUC® PUR 351 EC (MD) is a medium-heavy AIRDUC® profile hose. Its official construction includes a spring steel wire firmly embedded in the wall and an electrically conductive premium ester-polyurethane Pre-PUR® wall with an approximate wall thickness of 0.7 mm.
NORRES specifies this model as highly abrasion resistant with good resistance to oil, gasoline and chemicals, as well as 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.
NORRES states that AIRDUC® PUR 351 EC (MD) is in accordance with ATEX 2014/34/EU and German TRGS 727 for pneumatic transport of flammable dusts and bulk materials in Zone 20, Zone 21 and Zone 22 inside the hose, aspiration of combustible dusts in Zone 22 inside the hose, conveying flammable liquids in Zone 0, Zone 1 and Zone 2 inside the hose, conveying non-flammable liquids, and use in Zone 0, Zone 1 and Zone 2 for gases. The complete system design and actual installation requirements must be assessed before use.
The official operating temperature range is from -40°C to +90°C.
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.
