Earlier this year we posted an article covering the benefits and applications of compact flanges. This time we take a closer look at the equipment and kits you need to carry out machining on the flange sealing faces of a compact flange.

But first, a reminder about what makes compact flanges different to standard raised face flanges...

Are lead times for portable machine tools causing you problems?

Posted by Alan Hillier on Sep 21, 2016 11:29:53 AM




So you’ve done your research, you’ve found the right in-situ machine and the price is well within your budget.  Now you just want to get your hands on your shiny new kit and get your machining project underway as soon as possible.

So what’s the problem? – don’t all portable machine tool suppliers keep products in stock ready for despatch?    

Unfortunately, not. The feedback we’ve gained from new Mirage customers and our global distributors is that some companies are choosing to make their standard machines to order - resulting in lengthy lead times of around 14 weeks. In the worst cases this even applies to spares and accessories!

Let's find out how you can get what you need without waiting an unreasonable amount of time...

Choosing the right flange surface finish. An overview of ASME, ESF and FSA guidelines

Posted by Alan Hillier on Sep 7, 2016 9:30:00 AM




The flange surface finish for the sealing area is commonly represented by the symbol Ra. Irregularities in the surface can impact upon the effectiveness of the gasket’s ability to close potential leak paths and the friction values needed to keep the gasket in position.

Those new to this field of engineering are liable to incorrectly assume that a smoother finish will provide a better seal. But this isn’t necessarily the case. This subject has been debated over many years and the optimum flange surface finish really depends upon each individual application.

How to identify and repair flange face corrosion

Posted by Alan Hillier on Aug 25, 2016 9:36:48 AM



The problem of flange face corrosion

Piping systems in petrochemical refineries and oil & gas installations rely on hundreds of bolted joints which are exposed to corrosive conditions.

To ensure safe operation at these plants it is vital to carry out regular inspection to assure joint integrity is maintained. Until recently, the normal procedure to do this was to physically disassemble each flange joint to check on its condition. Using this method was costly as it required shutdown and in many cases is entirely unnecessary. Before we look at the alternatives lets first take a look at the different types of flange corrosion.
