Clamp profile hoses (CP)

Construction description

The CP construction combines single-, double- or multi-layered strip materials in a clamping profile. An embedded wire holds the strip firmly in the clamping profile and prevents it from slipping out under pressure or dynamic load. The clamping profile itself has a special drop-shaped geometry with a round inner edge and rounded ends — that geometry is what makes the construction distinctive.

The drop-shaped clamping profile gives a high geometric moment of inertia, translating into high compression strength and high vacuum load capacity. The round inner edge distributes the clamping force evenly around the strip material and avoids point stress peaks that would weaken the seal. The rounded ends act as a protective baffle around the strip material and give the construction high dynamic load and high overpressure capacity. The result is a hose that withstands both positive and negative pressure without losing its shape — while supporting a high-performance strip material that does not slip or deform.

Variants

Single-layer CP

The simplest CP construction: one strip material clamped in the profile. Suited when a single core property is critical — for example chemical resistance, thermal resistance or high flexibility. The drop-shaped clamping profile gives the construction its high vacuum capacity and compression strength independently of the number of layers.

Single-layer

Multi-layer

HYP / ARAMID PROTECT

Multi-layer CP

The multi-layer construction combines multiple strip materials in the same hose. It allows you to choose properties layer by layer: an outer layer for external abrasion resistance, an inner layer for chemical resistance, an intermediate layer for thermal or acoustic insulation. The multi-layer variant typically gives better internal impermeability than single-layer, and is the preferred construction when several properties must be achieved in the same hose.

CP HYP 450 PROTECT and CP ARAMID 461 PROTECT

The PROTECT variants add an outer protective profile in elastic material — an extra geometry on top of the clamping profile itself. The protective profile provides impact resistance and elevated abrasion resistance when the hose is dragged across floor, chain or machine surfaces. The specially developed protected geometry secures firm clamping against slippage, and a beading at the end of the profile provides additional resistance to slippage.

CP HYP 450 PROTECT uses HYP (hypalon/CSM) as the strip material — chemically and UV resistant. CP ARAMID 461 PROTECT uses aramid fibre — high thermal and mechanical stability. The protective profile can be supplied in any colour.

Properties

• High external abrasion resistanceThe clamping profile sits outermost and takes the wear first — the strip material itself is protected.
• High compression strengthThe drop-shaped clamping profile provides a high geometric moment of inertia.
• High vacuum load capacityThe same drop-shaped geometry provides good vacuum capacity — particularly in the multi-layer variant.
• Even clamping force distributionThe round inner edge of the clamping profile ensures no spot gets a point stress peak.
• High dynamic loadThe rounded clamping profile ends protect the strip material and provide high resistance to repeated loads.
• Selective adjustment of propertiesThe multi-layer variant lets each layer be dedicated to a specific property — chemical, thermal, acoustic.
• Improved impermeability (multi-layer)Multiple layers increase sealing security — important when the medium must be contained without leakage.
• Thermal and acoustic insulation (multi-layer)The layered structure can be used to dampen heat and sound transmission through the wall.

Applications

The CP construction is typically chosen wherever a hose must withstand high external wear, handle large positive and negative pressure swings, or combine multiple material properties in one hose. Concrete application areas include high-temperature extraction, chemical transport where a particularly resistant liner must be combined with a mechanically robust outer construction, and demanding industrial applications where the hose is dragged across the floor or chain during operation.

The HYP and ARAMID PROTECT variants are reserved for situations where wear and chemicals or heat are simultaneous challenges — for example chemical loading, high-temperature exhaust and processes where impact loading is expected.
