Flexible Hoses: What You Need to Know About Installation


Using a flexible metal hose correctly is of vital importance as the health and safety of employees is vitally important, alongside the continuous workflow of daily production. There are various precautionary measures to take before even thinking about the hose installation process.

The first precautionary measure to take is to check that the hose is the correct application for the job at hand, as having the right material, pressure rating, chemical resistance and temperature sustainability is vital for the performance of your hose and machinery. Thoroughly examine the hose for any noticeable or obvious signs of damage. Common signs of damage can include the fraying of wire braiding, dents or crushing that may result in a reduction of the hoses lifespan or pressure rating.

The movement of a flexible metal hose should be limited to a single plane. There should also be a restriction to the amount of twisting that can potentially occur, as pushing the bend of a hose to an extreme will almost certainly cause a limitation in transferring workflow and become detrimental to the hoses lifespan and health and safety.

When installing your flexible metal hose make sure to never go below the minimum bend radius as the radius is set to each specific hose during the manufacturing process. It may be obvious to some that forcing the hose beyond its bend radius can be incredibly detrimental; however, failing to maintain the minimum bend radius can be just as detrimental if not more.

Using elbows that are specifically designed to reduce severe bending can prevent overstressing the hose assembly and material, which will inevitably cause the hose to fail. If you need to bring the hose to a bend that could be classed as severe then make sure to use those elbows to completely remove the chance of failure caused by overstress.

The installation process for flexible metal hoses is incredibly complex and failing to carry out each action correctly can result in severe failure. Contacting reliable industry specialists in your area for advice and information on the right products and techniques is an absolute must.

Industrial Hose Reels & Their Conveniences

Wear and tear can occur if your hose is simply left out for extended periods of time in a hectic, possibly dangerous, working environment. Industrial hoses on a reel keep everything within the application in top condition, removing the chances of unnecessary damage that will require a replacement and subsequently a large cost. The organisation of several industrial hoses in one business can be an absolute nightmare. The space that is required when storing a regular hose can become quite detrimental, so utilising the space saving benefits of a hose reel can save on space and provide a storage area for so much more. Retractable hose reels are designed with features that allow them to be easily mounted on to walls and ceilings, leaving you to utilise the maximum amount of storage and work space as possible. Other reels are designed to be mounted on trucks and heavy duty vans, so if you happen to have a fleet of vehicles that are capable of having reels fixed to them, you can com...

The Basics Behind Industrial Hoses

Industrial hoses are an incredibly useful tool in a variety of manufacturing and production processes. Their characteristics and accessories can be equally variable, so it is vitally important that you know the basics of an industrial hose and how they can benefit the efficiency of workflow within your industry sector. Here we will look at the precise specifications that contribute to industrial hoses. An industrial hose is a flexible container that takes a shape similar to a pipe, and is quite often made of rubber. These “pipes” are used to transport liquids, gases and certain solids from one part of a machine to another, or even a completely different area of the building. Household hoses that a majority of people are familiar with will usually include the common garden hose; however, industrial hoses are used when larger volumes of substances are in need of transportation. Hoses transport those substances via their water-tight lining made of plastic or rubber, which is als...

Chemical Analysis, NAP XPS

NAP XPS is a less traditional form of XPS (x-ray photoelectron spectroscopy), it allows for samples to be analysed at relatively high pressures. Through using the NAP XPS, the XPS can efficiently and effectively probe biological samples, porous materials, moderately volatile liquids or even polymeric materials that outgas significantly.  Chemical analysis is the act of decomposing a substance into its constituent elements. Chemical analysis, which heavily relies on the use of accurate measurements, is divided into two categories depending on the manner in which the assays (the process of determining proportions of metals) are conducted. Classical analysis, also known as wet chemical analysis, is made up of analytical techniques which require no mechanical or electronic instruments other than a balance. This method usually relies on chemical reactions between the material being analysed and a reagent that is added to the material. Wet techniques often depend on the ...
