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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES CP PE 457 EC hoses for customers throughout Malaysia requiring an electrically conductive polyethylene clamp profile hose for flexible ducting of gases, dust, powder and fibres.

NORRES CP PE 457 EC is an electrically conductive polyethylene clamp profile hose, also known as a clip hose. Its CP construction uses a galvanised steel clamp-profile supporting spiral together with an electrically conductive polyethylene wall.

The external clamp profile provides abrasion protection, while the hose wall is securely clamped within the clamp profile. NORRES officially lists CP PE 457 EC as highly flexible and compressible 4:1.

NORRES officially lists this model for flexible hose and ducting for gases, dust, powder and fibres. Listed applications include extraction arms, chemical vapours, vapour return hoses at loading arms, paint steam and spray mist extraction, as well as use in explosion-hazard areas.

NORRES specifies an electrically conductive wall with electrical and surface resistance below 10³ Ω. The official product information also states compliance with ATEX 2014/34/EU, 1999/92/EC and German TRGS 727 for the listed applications and operating zones.

NORRES lists good resistance to alkalis and acids together with extremely good resistance to chemicals. The official operating temperature range is -35°C to 80°C. The standard hose colour is black, while stainless steel INOX clamp-profile versions are available as a delivery variant.

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 CP PE 457 EC?
A: NORRES CP PE 457 EC is an electrically conductive polyethylene clamp profile hose, also described as a clip hose, for flexible ducting applications.

Q: What applications are officially listed for CP PE 457 EC?
A: NORRES lists flexible ducting for gases, dust, powder and fibres. Official applications also include extraction arms, chemical vapours, vapour return hoses at loading arms, paint steam and spray mist extraction.

Q: Is CP PE 457 EC electrically conductive?
A: Yes. NORRES specifies an electrically conductive hose wall with electrical and surface resistance below 10³ Ω. NORRES also references NFPA 652 with a value below 10⁶ Ω.

Q: Is CP PE 457 EC suitable for explosion-hazard areas?
A: NORRES states that this model is in accordance with ATEX 2014/34/EU, 1999/92/EC and German TRGS 727 for specified applications. These include aspiration of combustible dusts in Zone 22 inside, use in Zone 1 and Zone 2 for gases, and use in Zone 0 for gases. The complete system and installation requirements must still be checked before use.

Q: What is the hose construction?
A: The official CP construction uses a galvanised steel clamp-profile supporting spiral and an electrically conductive polyethylene wall.

Q: Is CP PE 457 EC flexible and compressible?
A: Yes. NORRES officially lists CP PE 457 EC as highly flexible and compressible 4:1.

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

Q: Is CP PE 457 EC resistant to acids, alkalis and chemicals?
A: NORRES lists good resistance to alkalis and acids together with extremely good resistance to chemicals. Actual suitability must still be checked against the specific chemical, concentration, temperature and duration of exposure.

Q: Can CP PE 457 EC be used under pressure or vacuum?
A: NORRES provides size-specific recommended overpressure and underpressure values. The permitted pressure, vacuum and bending-radius values vary by hose diameter and must be checked against the official technical table before final selection.

Q: How should the correct CP PE 457 EC size be selected?
A: Select according to the required airflow, conveyed material, hose diameter, pressure, vacuum, temperature, bending radius, installation layout and required hose length. NORRES lists standard inner diameters from 50 mm to 800 mm, with further diameters and lengths available on request.
