What are spiral wound gaskets?

Posted by Alan Hillier on Jun 11, 2018 4:48:00 PM

what-are-spiral-wound-gasketsThe spiral wound gasket was developed in the early 20th century to meet the increasingly demanding conditions encountered in oil refinery operations. This type of gasket is commonly used with flange surface finishes created using Mirage flange facing machines, which is why we decided to put together this simple overview as an introductory guide for the on-site machinist.

2 examples of on-site applications for Mirage Flange Facing Machines

Posted by Alan Hillier on May 10, 2018 4:01:00 PM


Since we started this blog back in 2013 we've covered many different topics, including,  industry news, machine specifications, infographics, machining tips and much more. Wherever possible, we've tried to include bespoke projects and real life applications and these have been well received,

When it comes to flange facing projects, these are usually simple 'quick-fix' tasks, which on their own, haven't warranted the creation of 'in-depth' articles. Our flange facers are so easy to set up and operate, which means there's not a great deal of scope for detailed case studies. So how can we demonstrate they perform to expectations out in the field? 

Here's two very simple real life applications where Mirage Flange Facing Machines were used to repair damaged flanges within a tight timescale.

On-site machining opportunities: Nuclear power plant project list

Posted by Alan Hillier on Feb 20, 2018 9:04:00 AM


Considering the negative media coverage over the past few years, you’d be forgiven for thinking that nuclear power is out of favour and is in a state of terminal decline. Whilst this may be the case in some countries, for many others, the ‘pros’ of reducing greenhouse gases and other emissions from fossil fuels outweighs the ‘cons’ of potential nuclear accidents.

This continued demand for new nuclear power plants combined with the need for decommissioning of older nuclear installations presents attractive on-site machining opportunities for contractors, large and small.  Using information sourced from the EIC (Energy and Industries Council), we’ve listed some sizeable nuclear power projects you may be interested in.

Using dial indicators for flange facer set up

Posted by Alan Hillier on Jan 23, 2018 11:53:58 AM


Overview: The Dial Indicator

The dial indicator is a must-have item for the on-site machinist. They accurately indicate small distances and angles and ‘amplify’ them, making them easy to read. Typical applications for the in-situ machinist include flatness and ‘run-out’ on items before and after machining, or as part of the machine set up process.
