Stress Orientated Hydrogen Induced Cracking (SOHIC) is a potential problem found in steel pressure vessels, boilers and pipes deployed in sour service, primarily within the oil and gas industry. So what exactly is SOHIC, what damage can it cause and what measures can be taken to avoid it happening in the first place?
SOHIC Explained
Stress orientated hydrogen induced cracking occurs in sour service installations. Sour service is a working environment where there are significant levels of hydrogen sulphide present, and such environments are common in the oil and gas industry. Steel boilers and pressure vessels used in sour service can corrode from the inside due to the build up of hydrogen sulphide. Similar to hydrogen induced cracking (HIC), stress orientated hydrogen induced cracking is different due to the fact that it effects the heat affected zone (HAZ) of welds since this is the weak point in the pressure vessel or pipe. Failure to detect corrosion in this area could cause the pipe of pressure vessel to fail with potentially dangerous consequences.
It is therefore important that the steel procured has been tested for susceptibility to the effects of hydrogen sulphide corrosion in some way. Whilst a specific SOHIC susceptibility test has not been standardised within the industry as of yet, HIC testing is available for particular steel grades used in this instance.
The testing procedure essentially involves the evaluation of resistance of pressure vessel, boiler and  pipework steels to hydrogen induced cracking caused by hydrogen absorption from aqueous sulfide corrosion. An unstressed steel sample is exposed to a solution at ambient temperature and pressure. After a designated period, the sample is removed and assessed. The results of this test determines the materials suitability for the purpose intended. This will provide the customer with confidence as to how long the material is likely to last before replacement is required.
Steel grades of this type can be tested by the mill, by a UKAS approved testing agency or a specific test criteria can be provided by the customer.

CO2 emissions are continuously making headlines in today's media. Yet, with all the hype, it's difficult to get a grasp of what it's all about. What is the link between all this CO2 and me? If I can answer that question, then maybe I can begin to understand how I can help.
The four biggest causes of CO2 emissions in the UK are Power Plants (27.5%), Industry (24%), Transportation (24%) and Residential (17%). *approximations are taken from UK Energy Predictions (UEP)
Power plants burn fossil fuels to produce electricity to power Britain. Emissions from the industrial sector are due to processes like cement, lime, iron and steel production. Transportation is the third major cause of CO2 and residential homes are the fourth, through electricity usage and the direct combustion of fossil fuels for heating.
So, the biggest cause of CO2 emissions in the UK is the generation of electricity in power plants. If I can cut down my use of electricity, both directly and indirectly, then this will help reduce power plant emissions. How do I do this? Well, the UK's national grid powers 3 main areas; industry, the domestic sector and the services & agricultural industries.
Firstly, I can help reduce the amount of electricity needed in the Industrial sector. I can stop contributing to consumer demand and try to live more within my means. I can sit down with my calculator and work out how much I spend on consumables or goods each month and then decide what I can cut out. Not only will I save money, I'll be saving the planet too!
Secondly, I can cut down on the amount of electricity I use in the home. I can unplug electrical appliances when I'm not using them, I can buy energy efficient light bulbs etc.
Thirdly, I can help reduce electricity usage in the services and agricultural industries. When leaving my workplace, I can make sure I unplug my computer and printer and turn off lights when I leave a room. I can grow more of my own produce and buy organic to reduce the amount of industrial machinery needed in agriculture. The other major contributors to CO2 are industry, transportation and the residential sector. I've already started on reducing the impact from the residential sector - I could probably be a bit more economical with my gas central heating as well as electricity. Throwing on a couple of extra layers instead of cranking on the heat, putting an extra blanket on the bed etc. There's not so much I can do about the industrial sector as far as cement, lime, iron and steel production are concerned. But I can certainly help reduce the carbon footprint of transportation... that's just a matter of getting on my bike! I can start cycling and walking instead of driving, wherever possible.
This way, I'll reduce CO2 emissions from transportation and get some much needed exercise at the same time. By understanding the direct and indirect links between our own everyday lives and CO2 emissions, we can all start to grasp how and where we can help. It is reported that if everyone in the UK installed just one energy saving light bulb, we'd save enough CO2 to fill the Albert Hall over 1,900 times!! We don't need to have a complete lifestyle overhaul, we don't need to turn ourselves into the 'Good Life' and become completely self-sufficient (though that is sounding more appealing by the day!) Small and simple steps can make a huge difference. It's easy when you know how.

Best Stainless Steel Toasters
This article will guide you to the best of the stainless steel toasters and their features. We say, understanding the toasters is as easy as enjoying the crispy toast on the breakfast table. Moreover understanding the toaster will help you in using your toaster in a better way if you already have one or buy the best one if you are going in for a new toaster. In most ways an electric toaster is not a complex device, but if you look at it closely you will find much things happening beneath your toaster cover. All we know is the basic principle of bread getting in the toaster slot, then due to the heating elements the slots get hot, and once the toast is ready the slot pops it out. Lets understand the working of a stainless steel toaster.
In the stainless toaster a rider present in the slot grips the bread. It carries down the bread right into the slot as soon as the toaster’s handle is depressed. To toast the bread, the grates close around to center it and an electromagnet holds the rider down until the timer is triggered. This is how any basic stainless steel toaster works. But to buy the best stainless toaster you should require at some more important and functional areas of the stainless steel toaster. It is better to look for some important features that are very essential while choosing the best from the rest. Features in a stainless steel toaster may vary but some of them are really essential for a hassle free toaster.
Some of the must have features in any stainless steel toaster are listed for your information. Looking at the quantum of toasts you require every morning you can choose from the two slice toaster or the four slice stainless steel toaster. If the toaster offers some extra wide slots then it is much better option to look for. Any stainless steel toaster should be handy when it comes to cleaning. Not only the outer shell but also the crumb tray should be removable for easy cleaning. Many stainless steel toasters offer the defrost function that helps unfreeze the frozen bread. A toaster is not only used for breads but many of you may also use it for toasting bagels, so look for this feature as well. For more flexibility many of the stainless steel toasters also offer reheating of the toast without browning it. In fact some do also have the browning control feature to give you the desired browning on any toast. Many of the toasters also feature self-centering bread racks for even toasting. Another interesting and important feature for the maintenance of the toaster is the toaster cover which keeps the device clean when not in use. Simple but important the cancel switch stops toasting immediately if you wish for it. With all these features, the stainless steel toasters are definite to give you a lasting service and many evenly toasted breads.
