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

NORRES AIRDUC® PUR 351 HT (MD) is a medium-heavy high-temperature hose. NORRES specifies an AIRDUC® profile hose with a spring steel wire firmly embedded in the wall. The hose wall is made from patented special premium high-temperature polyurethane HT-PUR (Pre-PUR®) with an approximate wall thickness of 1.0 mm.

NORRES states that AIRDUC® PUR 351 HT (MD) is highly abrasion resistant and provides very good heat resistance compared with comparable TPE and Neoprene. The official product information also states good resistance to oil, gasoline and chemicals, as well as very good low-temperature flexibility.

Official NORRES applications include flexible ducting for high throughput of warm abrasive powder, bulk material, granulate and warm gases. NORRES also lists film blowing machine cooling air at the extrusion tool, offset printing machine air supply and air supply cabinets, UV dryer and IR dryer air supply, textile-industry steam soaking equipment, 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.

NORRES lists black as the standard delivery variant. 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.
