Hydrostatic Pressure Testing: The Ins & Outs

Hydrostatic testing is one of several testing methods based around pressure to ensure the functionality of any pipes or industrial hoses and the safety of employees who work in the vicinity of these pipes and hoses on a daily basis. If one of these pipes or hoses fails during the working day it can become incredibly detrimental to business and productivity. Ensuring the reliability, durability and detection of leaks, cracks and irregular bends will provide a certain level of security to productivity, efficiency and safety.

The responsibility of pressure testing for efficiency and safety is down to heads of the company, with assistance and leading from pressure testing professionals. The results collected by these individuals provides detailed information on exactly how reliable the pipe or hose is, and if it may be worthwhile to replace them before an accident occurs.

The commonly used hydrostatic pressure testing method uses completely clean water to apply pressure inside the gas pipes and hoses. After the test is completed and the results are collected, the pipes are then dried thoroughly and eventually a decision will be made as to whether to pipe or hose is still fit for purpose.

It is incredibly important to have a sharp focus on health and safety when performing these tests. Despite the beneficial purpose of hydrostatic testing, it is still a method that uses pressurisation, which can cause harm to those performing the test and to those in the vicinity. Below are some basic health and safety points to keep an eye out for.

Ensure the gauges are all functioning correctly and are in an easy-to-read area to provide an accurate reading.
Make sure any personnel who are not required to be in the test are removed from the test area before starting.
Make sure the pressure test tools have also been tested beforehand to ensure an accurate reading.
It is vital that a safety relief valve or safety feature is correctly installed for emergencies.
When pressurising hoses it is essential to tie down any hoses to avoid any accidents.
Wear the correct pressure testing clothing and safety equipment.

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 ...
