The oil and gas industry plays a very important role in the global energy supply as well as the world economy. Many technologies are crucial to the existence and functioning of this multi-billion dollar industry. One of these is welding.
The oil and gas industry utilizes various highly complex infrastructure such as rigs, pipelines, platforms, plants, and facilities. The majority of these infrastructures are created using welding technologies. Welding is critical in oil and gas operations both for the construction of new projects and for the maintenance of existing facilities.
Applications of Welding in Oil and Gas
The oil and gas industry is divided into three major stages of operation. These, which can be referred to as sectors, are Upstream, Midstream, and Downstream. Welding is widely used across all these sectors and its applications can be classified accordingly.
Whether you’re working in the petrochemical, manufacturing or food and beverage industry, plant shutdowns are inevitable. Plant maintenance is vital to optimizing peak performance of a facility to ensure profitability, safety and regulatory compliance.
From a routine plant shutdown and maintenance period, metrics such as quality, schedule and cost can be measured and planned in advance. However, exceptions such as the global outbreak of COVID-19 global pandemic can pave the way for unexpected maintenance opportunities. In a move to contain the virus spread, companies close up shop temporarily to follow government mandates, protect their employees and take advantage of the opportunity to perform deep-cleaning routines using technologies like dry ice blasting on their factories simultaneously.
Pre-weld and post-weld heat treating is critical for many welding operations. Without proper thermal manipulation, welds and heat affected zones can have mechanical properties that are undesirable. Worse yet, inadequate heat treatment can result in cracks and devastating weld failures. While temperature and time are the primary concerns when heat treating a weld, the heating method should also be considered diligently when selecting a process. Induction heating is one of the most popular types of heat treating methods, and rightfully so. The benefits of induction heating are many, and Red-D-Arc has the equipment you need to successfully implement an induction heat treating operation for your projects.
Inspection, Surface Prep and Non-destructive Testing
Are you in the oil & gas industry? Are you involved in non-destructive testing, inspection, or surface preparation? How about maintenance of pipelines, heat exchangers, or pressure vessels? If you deal with these or similar operations, proper cleaning of surfaces might well be a process you regularly undertake.
Cleaning Delicate Equipment Safely
What is the best way to clean surfaces of such equipment? While there is no one best way for every circumstance, dry ice cleaning is a state-of-the-art method that can save time and money. It uses recycled CO2 in the form of solid dry ice particles as the cleaning media. Dry ice is soft and non-abrasive to most surfaces and can thus be used around delicate components, including electronics, that would be damaged by water or solvents. As the blasting equipment is portable it can be used in place, thus minimizing disassembly and other preparation time. Lastly, dry ice turns to a gas after contact with the surface being cleaned — cleanup time is rock bottom minimum, there is nothing to dispose of, contamination of moving parts is not an issue.
To begin, let’s establish what exactly we’re talking about when we say “biodiesel.” ASTM (American Society for Testing and Materials) has published a standard, D6751-07b, that defines what biodiesel is. We’re not talking about used cooking grease, or even commercially produced biodiesel, if it doesn’t meet this standard.
Also, the word “biodiesel” is often used to describe what is actually a blend of biodiesel and diesel fuel. (The diesel fuel sold for on-road use in the U.S. is Ultra Low Sulfur Diesel fuel, or ULSD.) The term “BX” designates the blend ratio, where “X” stands for the percentage of biodiesel in the blend. So B100 means 100%, or pure, biodiesel, while B20 means 20% biodiesel mixed with 80% ULSD.
Additionally, this article doesn’t address OEM recommendations or warranty limitations. We’re simply looking at the question from a mechanical standpoint.
So now, with all that out of the way, what’s the bottom line?
