Understanding Flexible Metal Components

A flexible metal hose is used to transfer media under varying pressures and temperatures. These metal hoses must be incredibly resilient to these pressures and temperatures in order to successfully transport the media from one part of the machinery to another. A flexible metal hose must be able to resist the working environment that surrounds the hose such as severe vibrations and potentially damaging materials that may leak from other components. Here we will look further into these components to fully understand the uses of a flexible metal hose.

A metal hose assembly will consist of a corrugated hose that is both leak-proof and resilient to varying pressures. These hoses will often be braided in order to absorb as much damage and force as possible, to prevent any severe damage to the hose assembly that could cause disruption to daily workflow. It is common to attach a PTFE liner that increases the stability of the hose, establishing further resistance to chemicals and other media that may result in a loss of pressure, media, or workflow.

A corrugated metal hose is a thin-walled, cylindrical component that forms a corrugated surface area. There are two types of corrugation used; annular and coil. An annular corrugated metal hose will have a large amount of corrugations that are equally spaced and parallel to one another. A helical hose will have a predominantly right handed helix that runs through the entire length of the metal hose. An annular hose is often the preferred choice due to their ability to withstand a sudden increase in pressure.

The pressure resistance and flexibility of a corrugated metal hose makes them perfect for an extensive range of industries and working environments. Their leak proof attributes and robust nature are often used in the following applications: 
  • For transporting liquids, gases, and chemicals under varying pressures
  • As a vacuum pipe
  • As a flexible contention that absorbs vibrations and movements, alongside expansion from heat.

Should you require further insight into the attributes and benefits of a flexible metal hose, do not hesitate to contact your local hose management company. They can provide a wealth of knowledge and experience to help you understand why almost all industries use metal hoses during daily production.

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 ...
