CP HYP 450 INOX
CP HYP 450 INOX is the version of CP HYP 450 with a stainless steel supporting spiral instead of galvanised steel. The hose is highly flexible and compresses in a 4:1 ratio. The manufacturer states a normal temperature range from −40 to +170°C. It is used for gas and dust and is supplied in 11 standard sizes from inner Ø 45 to 325 mm.
- −40 to +170°C
- Stainless steel spiral
- Highly flexible, compressible 4:1
- Gas and dust
- HYP wall with clamp profile
- Cut to length
Why this hose?
CP HYP 450 INOX has the same HYP wall and clamp profile as CP HYP 450; the difference is the supporting spiral, which here is stainless steel. It is the version for installations where galvanised steel in the hose is to be avoided.
The hose is highly flexible and compresses in a 4:1 ratio, which makes it easy to route through tight installations and to store. The manufacturer states a normal temperature range from −40 to +170°C.
Where it is used
The hose is used for extraction of hot and cold gases and of dust where the supporting spiral must be stainless steel.
The formal name is CP HYP 450 INOX. In daily use: "the HYP hose with stainless spiral".

Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.
Standards and compliance
The hose is certified or documented to the following standards:
- REACH (EC 1907/2006) and RoHS 2011/65/EU. The manufacturer holds declarations of compliance, available under Documentation.
The manufacturer states no electrical resistance for the hose, so it must not be used for combustible dust.

Help with material selection
Even though this hose is not ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:
Industries that use it
The hose is used where gas and dust are extracted:
In the chemical industry and in extraction and filtration systems it is used for gas and dust.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies.
We offer guidance on material choice, coupling system and grounding, so the hose fits correctly into the overall system. If there is any doubt about zone classification or resistance requirements, a short conversation before ordering is well worth the time.
Frequently asked questions
What is the difference between CP HYP 450 INOX and CP HYP 450?
The difference is the supporting spiral: stainless steel on CP HYP 450 INOX, galvanised steel on CP HYP 450. Both have a HYP wall and clamp profile. Which one fits depends on the process and the surroundings; ask us if in doubt.
How do I order the hose, and where do you deliver?
The hose is ordered through Particulair (Karlslunde, Denmark). We deliver to Denmark, the EU and selected third countries such as Norway and Switzerland. Standard dimensions can typically be delivered in 1-2 weeks; custom assemblies and larger volumes require slightly longer lead time.
What is the hose's expected service life?
Service life depends on operating conditions: loading, temperature, chemical exposure, UV and mechanical movement. In standard industrial use, expected life is 3-7 years. Aggressive conditions (high temperatures, continuous flexing, chemical vapours) reduce service life. We recommend regular visual inspection for cracks, deformation or discolouration.
How is the hose best stored before use?
Store the hose dry, at room temperature (15-25°C) and out of direct sunlight. Avoid contact with ozone-generating equipment (welding equipment, engines). If stored on a reel, the bend must be larger than the specified minimum radius to avoid permanent deformation. Proper storage significantly extends shelf life.
What is the minimum bend radius, and what happens if I go below it?
Minimum bend radius is the smallest radius the hose can be bent to without permanent deformation or internal damage. The table above shows specific values for each dimension. Bending the hose below this limit can collapse the wall, kink the spiral or damage the inner coating. The result is reduced flow, increased pressure loss and shorter service life. Always use bend radius as a design constraint in installation.
Which chemicals is the hose resistant to?
Specific chemical resistance depends on material selection, concentration and temperature. The manufacturer maintains an extensive chemical resistance table showing compatibility for hundreds of chemicals. It can be downloaded from the Documentation section above. If in doubt about a specific chemical or mixture, contact Particulair — we can advise based on your concrete process.
Does temperature affect the hose's chemical resistance?
Yes, significantly. Higher temperatures accelerate chemical attack and reduce the material's resistance. A hose fully compatible with a chemical at 20°C may be underrated at 60°C. The manufacturer's chemical resistance table typically lists values at 20°C; at higher operating temperatures, compatibility must be reassessed. We always recommend a consultation before choosing a hose for chemical transport at elevated temperatures.
