Hot tapping into water lines using a LPHT Hot Tapping Machine

Posted by Alan Hillier on Mar 16, 2018 6:36:00 AM


The Mirage LPHT is a low pressure hot tapping machine, making it ideal for use on utility pipelines, such as water and gas lines requiring where holes from 3” up to 12”. This compact and portable machine is available with a choice of pneumatic and hydraulic drive motors used to rotate the cutter. The feed on this machine is advanced manually using a hand wheel up to a maximum stroke capacity of 30”.

Lens ring flange joints and how they are machined

Posted by Alan Hillier on Mar 6, 2018 4:03:37 PM


The Lens ring type of flange joint is used to create a seal in high temperature and high pressure piping systems. This joint differs from the standard raised face flange joint (which has a ‘flat’ sealing face), by having a sealing face angled at 20° down towards the centre of the bore. This type of joint is not used on very large flanges, with typical outside diameters of the lens ring gaskets ranging from 20mm up to 385mm.

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.

In Focus: VHT gate valve drilling machines

Posted by Alan Hillier on Feb 15, 2018 11:04:00 AM


The VHT series of machines has been designed for wellhead machining applications, such as when gate valves are seized. When this happens, one solution is to fit a new valve on top of the defective one and to machine a hole through the seized slab gate, allowing the product to flow through.
