In our previous blog post we listed a number of in-situ machining projects relating to power plant maintenance. This time we take a look at one of these in more detail, to and cover the equipment used and the results achieved.

As part of a turbine refurbishment project, Mirage equipment was specified to machine the casing split lines back to the original specification.  A Mirage MR2200 2 axis milling rail was used and mounted onto a Mirage gantry system. Let’s take a look at these in more detail.

When you consider the demands that turbine components in power plants are exposed to, it comes as no surprise that eventually many components will wear out and operate less efficiently. With steam turbine temperatures being of over 500°C, pressures of 4000psi and components rotating at speeds of over 3000rpm, the importance of a well-managed and robust maintenance programme cannot be overstated.  (Find out more about power plant maintenance strategies on our previous blog post).

Mirage orbital milling machines are used across a variety of industry sectors, especially those involving the manufacture of large circular components. The shipbuilding industry is a good example of this and one particular application which has cropped up several times is the machining of ship thruster flanges.

The expression ‘shifting sands’ is used to describe something that is constantly changing, especially unpredictably and that’s something that we’ve all witnessed in the oil and gas industry during recent times.  An example where this occurred literally was when Mirage was asked to help out when a natural shift in the level of sand was interfering with the operation of a wellhead Christmas tree in Kuwait.

Why do oil prices fluctuate?- An insight for oil and gas engineers

Posted by Alan Hillier on Oct 27, 2016 9:14:50 AM

Many of Mirage's customers are on-site engineering service companies, who use our portable on-site machining products for a wide range of oil and gas machining projects.  

The recent collapse in oil prices has made life very tough for these companies. Over production by OPEC (The Organization of the Petroleum Exporting Countries) has played a significant part, but as the infographic below published by Jones Oil shows us, there are many other factors which can also cuase oil prices to fluctuate.
