9 essential portable machine tools every wellhead maintenance engineer should know about

Posted by Alan Hillier on Oct 12, 2016 9:24:08 AM


There are many reasons why in-situ machining of wellhead components is required. They normally fall into one of three categories: it could be part of a preventative maintenance programme, when corrective action is needed, or if recovering the wellhead as part of a decommissioning project.

Valves and actuators used in a wellhead Christmas tree can fail through seizure and breakage, often caused by a lack of suitable lubrication and long periods of non-operation. Additionally, corrosion and erosion problems arise over a period of time, with hydrocarbons causing issues inside the valves and external components being either sand blasted by the wind, or exposed to corrosive salt-water.

So what portable machining equipment is available to help the on-site team commissioned to solve these problems? 

Below, we’ve listed 9 essential machines we think every wellhead engineer should know about.

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...
