Case study: specialised pressure reduction station in Malaysia

A pressure reduction station was installed at a Malaysian plant to reduce the pressure of between 30 and 80 tonnes per hour of steam from 106 to 3,5 bar. Mitech has recently supplied a specialised pressure reduction station for a Malaysian customer. The station is in steam let-down service, dropping between 30 and 80 tonnes […]

Resistance welding applications in electrical engineering, precision mechanics

The growing use of heavy-duty electronic devices and components in motor vehicles has led to increased use of previously unused or only rarely used bonding methods. While soft soldering and crimping were the most frequently used methods until just a few years ago, these methods are today reaching the limits of their possibilities due to […]

Rehabilitation for failing water piping

New to South Africa is a system which rehabilitates the inner infrastructure of deteriorated or failing water piping using an array of cured-in-place epoxy pipe lining solutions. SABMiller’s brewery in Okahandja, Namibia, had a drainpipe failure. The network of pipes affected run beneath epoxy coated 30 MPA concrete floors supporting the plant’s heavy machinery and […]

Case study: remote condition monitoring of London Underground track circuits

Delivering a reliable remote condition monitoring system for the London Underground to enable maintainers to respond to failures before they occur. London Underground serves 1,7-billion passengers per year and the Victoria Line accounts for 213-million of those journeys. The line carries 89,1-million passengers per year in the peak service, offering the most intensive service on […]

Fundamentals of laser welding

  There are two of types of neodymium-doped yttrium aluminium garnet (Nd:YAG) laser welder, continuous wave and pulsed. As the name suggests, continuous wave or CW is either on or off, whereas pulsed lasers create welds by individual pulses. The pulsed laser uses high peak power to create the weld, whereas the CW laser uses […]
