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 355 HT (HD) heavy-duty high-temperature polyurethane hoses for flexible ducting of warm abrasive powder, bulk material, granulate and warm gases.

NORRES AIRDUC® PUR 355 HT (HD) is a heavy high-temperature hose. Its official design is an AIRDUC® profile hose with a spring steel wire firmly embedded in the wall. The wall is made from patented special premium high-temperature polyurethane HT-PUR (Pre-PUR®) with an approximate wall thickness of 1.4 to 1.5 mm.

NORRES lists this model as heavy duty and highly abrasion resistant. The official product information also states very good heat resistance compared with comparable TPE and Neoprene, increased pressure and vacuum resistance, very good low-temperature flexibility, and good resistance to oil, gasoline and chemicals. NORRES lists AIRDUC® PUR 355 HT (HD) according to DIN 26057 Type 3.

Official NORRES applications include plastic-industry conveying of granulates and powders in granulate conveying equipment, vacuum hoppers, suction conveyors, dosing systems, bulk-bag charging and discharging systems, shredders, mills, extruders and injection moulding machines. NORRES also lists cooling air at film blowing machine extrusion tools, air supply for offset printing machines, textile-industry steam soaking equipment, raw-material conveying of powders, granulates, sand, quartz, gravel, shards and chips or shavings, as well as use with compressors, side channel blowers, vacuum pumps, pressure pumps and pumps.

The official temperature range is -40°C to 125°C, with short-time operation up to 150°C.

Current NORRES delivery variants include black and transparent hose versions. Further diameters and lengths are available on request according to NORRES.

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.

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