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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES PROTAPE® PE 322 EC (XLD) hoses for customers in Malaysia requiring an electrically conductive polyethylene hose for flexible ducting of gases and for dust, powder and fibre extraction applications.

PROTAPE® PE 322 EC (XLD) is a PROTAPE® tape hose with a spring steel wire integrated in the hose wall. The wall is made from electrically conductive polyethylene (PE) and has an approximate wall thickness of 0.3 mm.

NORRES officially describes this model as light, lightweight, highly flexible and compressible. The hose has good resistance to alkalis and acids, extremely good resistance to chemicals, and an electrically conductive wall with electrical and surface resistance below 10³ Ω.

Official NORRES applications include flexible hose and ducting for gases, dust, powder and fibres; extraction arms; galvanic extraction; chemical vapour extraction; vapour-return hose use at loading arms; paint-steam and spray-mist extraction; as well as ventilation and methane extraction for coal mines, mines and tunnelling applications.

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.

FAQ

Q: What is NORRES PROTAPE® PE 322 EC (XLD)?
A: It is an electrically conductive polyethylene hose from NORRES. The official product description classifies it as light and lists it for flexible ducting of gases and for dust, powder and fibre applications.

Q: Is PROTAPE® PE 322 EC made from polyurethane?
A: No. NORRES specifies that the hose wall is made from electrically conductive polyethylene (PE), not polyurethane.

Q: What is the hose construction?
A: It is a PROTAPE® tape hose with a spring steel wire integrated in the wall. The wall is electrically conductive polyethylene with an approximate wall thickness of 0.3 mm.

Q: Is this hose electrically conductive?
A: Yes. NORRES specifies an electrically conductive wall with electrical and surface resistance below 10³ Ω. NORRES also states a value below 10⁶ Ω according to NFPA 652.

Q: Can PROTAPE® PE 322 EC (XLD) be used in explosion-hazard areas?
A: NORRES lists defined uses in accordance with ATEX 2014/34/EU, 1999/92/EC and German TRGS 727. These include pneumatic transport of flammable dusts and bulk materials in Zones 20, 21 and 22, aspiration of combustible dusts in Zone 22, and defined conveying applications involving flammable liquids, non-flammable liquids and gases. The complete system and installation conditions must be assessed before use.

Q: Is this hose suitable for chemical vapour extraction?
A: NORRES officially lists chemical vapours, vapour-return hose use at loading arms, paint steam and spray-mist extraction among the applications. NORRES also states extremely good resistance to chemicals. Actual suitability must still be checked against the specific chemical, concentration, temperature and operating condition.

Q: What duty level does this hose have?
A: NORRES describes PROTAPE® PE 322 EC (XLD) as light and lightweight. It should not be described as medium-heavy, heavy-duty or super-heavy duty.

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

Q: What hose diameters are available?
A: The official technical table lists standard inner diameters from 40 mm to 250 mm. Pressure, vacuum and bending-radius values vary by hose diameter and must be checked against the official technical table before use.

Q: What is the standard hose colour?
A: NORRES lists black as the standard delivery version for PROTAPE® PE 322 EC (XLD).
