Anyone who believes that a hose is a trivial C product is mistaken. Even the construction is complex. Learn more about our hose designs.
Industrial hoses are complexly constructed products made of a wide variety of materials or material combinations. The reason for this diversity is the equally diverse applications of technical hoses.
In general, a hose consists of the following three elements: core, liner and cover.
The core refers to the material layer that lines the inside of the hose. This means that all pumped media come into contact with it exclusively. The quality of the inner component is therefore crucial for safe and high durability of the hose. The medium to be conveyed determines the selection of the core.
In order for a hose to become an industrial hose and withstand the various, often simultaneous, stresses such as temperature, overpressure or underpressure, flow velocity and permeation of the medium being conveyed, etc., for as long as possible, the optimum combination of material and hose design must be found for the respective application.
Here are the different hose constructions from our product range:
Tension-resistant connection between hose material and external material spiral (clip) by special clamping method.
Universal processing and combination possibilities for a wide variety of hose materials.
Extruded plastic profile with cast-in spring steel wire resistant to twisting and displacement.
Foils or fabric strips - helical, overlapping welded, with embedded support helix made of spring steel wire.
Foil and fabric strips - helically, overlapping welded, with attached support helix made of plastic or sheathed spring steel wire.
Overlapping wound vulcanized fabric strips with internally exposed or embedded spring steel support helix and additional external glass fiber cord fixation, for NEO 1/2 and SIL 1/2 hose types.
Inline and Performance Hoses
The manufacturing process of an inline or performance hose is the same as that of a standard profile hose except for the lining. First, a plastic granulate is melted and extruded into a plastic profile. In the process, a spring steel wire is cast into a plastic profile to prevent twisting and displacement. The hose is then helically and overlappingly welded to give it its final shape. Shortly after welding, the hose is filled from the inside with a cold-cast elastomer. The rotation of the hose creates the smooth inner layer in the hose. Our Master-PUR Performance has a wall thickness of 2.5 mm, whereas the Master-PUR Inline has a wall thickness of 5.5 mm.
Our Miniflex hoses, unlike our other hoses, do not have a potted spiral. The spiral is exposed on the inside of the hose. During production, a spring steel spiral is seamlessly coated from the outside with a thin TPU layer. The layer thickness is between 0.3 and 1.2 mm, depending on the wall thickness.
