It is undeniable that choosing the right materials and / or polymers for use as gaskets; hydraulic seals and rubber O-rings is essential for the success of any industrial process. However, of equal importance is ensuring that the coupling mechanism employed is equally compatible. In essence, getting the hose and fittings fitted guarantees that the hose can accommodate the degree of pressure that the fluid generates as well as ensuring that leaks and failures are kept to a minimum.
Assembling the hose
Any fitting that is attached to the end of a tube is known as an assembly. Most assemblies consist of a stem and a ferrule. The ferrule is a component (typically metal or a composite) that is set to grip and / or cover the hose. If a softer material is necessary, this will be attached to a hose by a metal clip. The stem refers to the fitting that is attached to the tube, whatever it may actually be or the use of the assembly itself. The stem almost always has a design that enables it to attach to a given set of ports, taps or adaptors. As if to underplay the importance of hose and fittings assembly, most manufacturers are continually striving to improve the quality and utility of the fittings that are attached to the hose. This means that the producers of these devices have purpose built research and development centres where engineers, technicians, chemists and metallurgists are employed to develop and improve the necessary materials.
Selecting hose and fittings materials
Choosing the right material for a given application is steered within a context of established industry standards with a healthy portion of sound judgment mixed with experience of what works in real settings. The factors to consider when selecting materials increases in line with the complexity of the process. For instance, avoiding corrosion requires that that the coupling equipment and piping are made of compatible material.
Hose and coupling application
The point, at which the hose and the assembly couple into the overall process, for example, the piping moving a fluid, is where the stress is going to be greatest. It is here that tiny leaks and blow-offs can occur and under any circumstances of high pressure they can be exceptionally dangerous. Imagine a corrosive alkali or concentrated precursor chemical being ejected from a system operating at hundreds of Psi and the thoroughly undesirable picture becomes apparent. Therefore, one parameter is to ensure that low-pressure couplings are never attached to high-pressure hoses. The use to which the hose and fittings are to be applied determines the way in which it will be operated in the production system as a whole. Here variables such as temperature, pressure, frequency of use, vibration from sound waves, motion of fluids, are integrated into the whole operating system. This means that if the material being handled is highly volatile or flammable then the material would need to be highly impermeable and chemically unreactive. In addition to these considerations it must be remembered that the relative temperature of the external and internal environment (i.e. the difference) can have a significant impact on the physical and chemical properties as well as the electrical conductivity of many materials.
Overall it is simply not enough to consider the material used in a particular production process. It is equally as important to consider how the whole mechanism is constructed and how materials are moved and transported within it.
