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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES AIRDUC® PE 362 EC (MD) hoses for customers throughout Malaysia requiring an electrically conductive polyethylene hose for flexible ducting of gases and for dust powder and fibres.

NORRES AIRDUC® PE 362 EC (MD) is an electrically conductive polyethylene hose with a medium-heavy duty construction. Its AIRDUC® profile hose design uses a spring steel wire firmly embedded in an electrically conductive polyethylene PE wall with an approximate wall thickness of 0.8 mm.

NORRES officially lists this model for flexible hose and ducting involving gases dust powder and fibres. Listed applications include chemical vapours vapour return hoses at loading arms paint steam spray mist extraction and selected coal mine mine and tunnelling applications for ventilation and methane extraction.

The hose wall is electrically conductive with electrical and surface resistance below 10³ Ω. NORRES also lists the product as having good resistance to alkalis and acids together with extremely good resistance to chemicals. The official operating temperature range is -35°C to 80°C.

NORRES states that AIRDUC® PE 362 EC (MD) is in accordance with ATEX 2014/34/EU 1999/92/EC and German TRGS 727 for its specifically listed hazardous-area conveying and extraction applications. The full hose system including fittings grounding installation and operating conditions must always be checked 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. The permitted pressure, vacuum and bending-radius values vary by hose size and must be checked against the official technical table before use.

Q: What applications are officially listed for this hose?
A: NORRES lists flexible ducting for gases and for dust powder and fibres. Other listed applications include chemical vapours vapour return hoses at loading arms paint steam spray mist extraction and selected mining and tunnelling ventilation applications.

Q: Is this hose suitable for explosion-hazard applications?
A: NORRES states that this model is in accordance with ATEX 2014/34/EU 1999/92/EC and German TRGS 727 for specifically listed applications. These include pneumatic transport of flammable dusts and bulk materials in Zones 20 21 and 22 inside as well as aspiration of combustible dusts in Zone 22 inside. The complete system must be assessed before installation and use.

Q: Can it be used with flammable liquids or gases?
A: NORRES lists defined applications for conveying flammable liquids in Zones 0 1 and 2 inside and use in Zones 0 1 and 2 for gases. These statements apply only when the full system including fittings grounding installation and operating conditions meets the applicable requirements.

Q: What is the hose construction?
A: NORRES specifies an AIRDUC® profile hose with a spring steel wire firmly embedded in an electrically conductive polyethylene PE wall. The wall thickness is approximately 0.8 mm.

Q: What is the operating temperature range?
A: The official NORRES operating temperature range is -35°C to 80°C.

Q: Is AIRDUC® PE 362 EC (MD) resistant to acids alkalis and chemicals?
A: NORRES lists good resistance to alkalis and acids together with extremely good resistance to chemicals. Final suitability must still be checked against the actual chemical concentration temperature and exposure duration.

Q: Can this hose be used under pressure or vacuum?
A: NORRES provides recommended threshold overpressure and underpressure values for each hose diameter. The permitted pressure vacuum and bending-radius values vary by hose size and must be checked against the official technical table before selection.

Q: Is AIRDUC® PE 362 EC (MD) food-grade?
A: The official NORRES product information for AIRDUC® PE 362 EC (MD) does not state a food-contact approval. It should not be selected for food-contact applications unless the applicable food-contact requirement has been separately confirmed.
