Helium in Vacuum Testing

At its most basic, vacuum testing is a process applied to industrial hose assemblies in order to detect signs of stress or leaks, and to ensure that the hose will remain sturdy during its daily operation. One of the more beneficial means of detecting signs of stress or leaks during a vacuum test is to use helium. Helium is ideal for collecting clear results in order to figure out the size of a leak and where it is located.

Here we will go into more detail about vacuum testing and exactly how helium can make the process much easier.

Firstly, and most importantly, helium is an incredibly safe way to detect leaks within industrial hose assemblies. Helium is a dormant gas that is also non-toxic - unless exposed to large amounts which can cause asphyxiation; however, this is highly unlikely to occur during a vacuum test. Another rather important “safety feature” of helium is the fact that it is inflammable. In an active working environment with various machinery and moving parts, an inflammable chemical is absolute necessity.

The presence of helium in our atmosphere is virtually undetectable, (within a testing environment of course), making the helium used purposefully within a vacuum test highly noticeable when collecting results. Helium also happens to be the smallest molecule other than hydrogen, (hydrogen being highly reactive and flammable), making it capable of detecting even the tiniest of leaks due to its significantly lower molecular weight

As you can clearly see, the use of helium in vacuum testing is incredibly beneficial for any and all industries looking to carry out industrial hose assembly tests on a regular basis. The results obtained are clearer and far superior when compared to other methods of vacuum testing, and provides a safer means to ensure the efficiency of manufacturing and production within the various industries.

Oil And Gas Prices Review: Bloated Supply Finally Clearing

In 2015, Oil and Gas Prices were at a historic 10 year low, through Saudi Arabia and Russia – both very oil rich countries – refusing to comply with OPEC instructions on maximum oil production. Crude oil, like all resources throughout the world – is subject to supply and demand – and both countries have pushed down global oil and gas pricing through overproduction throughout 2015. This has been catastrophic for the industry, as hedges of crude oil have become more of a burden to banks and governments due to lack of demand, low pricing due to competition of cheap Russian and Saudi oil, and has also meant that the hedges themselves are costing money, due to the costs of keeping them. The slump in prices has also meant that countries and banks have been unable to sell these hedges, as they are in negative equity – worth far less than already paid. As 2016 passed, the oil and gas industry buckled down and prepared for rough times, with oil and gas exploration and production at an ...

Understanding Hydraulic Testing

A hydraulic testing method is required to be carried out in a systematic manner, alongside a basic understand of the hydraulic system in question and its functions. Before the testing procedure begins, it is important to find the hydraulic schematic and the serial number for the system being tested. Here we will discuss further the importance of testing your system and how it can benefit you in the long term. If you have experienced the failure of a hydraulic component during a time that you can least afford it, or at an inconvenient time during daily production, then you are sure to benefit from testing your hydraulic system. A failure in your hydraulic system is an expensive circumstance. Every moment that your system is down and oil is spilling out at your feet is costing you money. It is essential to immediately identify the problem with your system in order to fix it; this is where a hydraulic test comes in. Hydraulic testing will allow you to easily and safely simulat...

How to Choose the Right Refrigerated Courier Service

Have you ever tried shipping fresh seafood or a life-saving vaccine across the country? Ensuring temperature-sensitive products remain in optimal condition during transit is crucial. The right refrigerated transport service can make all the difference, preventing spoilage and maintaining product integrity from pickup to delivery. The Risks of Choosing the Wrong Service Selecting the wrong courier can lead to serious issues: Spoilage and Waste – If goods aren’t kept at the right temperature, entire shipments can be lost, resulting in financial and operational setbacks. Safety Concerns – Food and pharmaceuticals that fall outside safe temperature ranges can pose serious health risks. Reputation Damage – Customers expect reliability. Poor delivery service can harm long-term trust and business relationships. What to Look for in a Refrigerated Courier Service 1. Temperature Control Capabilities Accurate Temperature Ranges – Whether transporting frozen food, chilled pharmaceu...
