How to specify gas struts accurately | Engineer Live
WEBMar 28, 2019 — Gas Spring Force (F1) = Mass of lid x Centre of Gravity / Radius of Force x Number of Springs. Closing Force Calculation. Similarly, the force required to close the lid (F2) can be calculated using the formula: Closing Force F2 = Number of Springs x Spring Force F1 x Radius of Force / Lid Length. Calculation of the opening and closing forces ...
What is a smart material? - Engineer Live
WEBMar 9, 2020 — A smart material is an object that holds a property that is susceptible to change with the introduction of an external stimulus. This change must be either tangible or visible for the material to qualify for ‘smart’ status. These changes can include: Electrical. Chemical. Thermal. Mechanical.
An Expert Guide To Sonic Drilling - Engineer Live
WEBMay 1, 2020 — Sonic drilling is a more efficient method of drilling by using high-frequency resonance to create a smoother path of travel for the drill by reducing or even eliminating any frictional resistance from subsurface materials being encountered. The high frequency resonance results in a vibrating head that is being both pushed up and down by the ...
A specifier’s guide to choosing the right filled PTFE material
WEBSep 13, 2016 — A specifier’s guide to choosing the right filled PTFE material. Phillip Charlton explores the main types of filled PTFE compounds, detailing the enhanced properties delivered by some key material combinations. The seldom rivalled hydrophobic, low-friction and corrosion-resistant properties of Polytetrafluoroethylene (PTFE) make it a highly ...
Positive displacement meters: pros, cons and selection
WEBFeb 21, 2013 — All PD meters require clean fluid so a filtration level of 100µm is usual. Some meters can actually block the flow if a larger particle is trapped in the wrong place. Many meters are not made in high specification materials and therefore corrosion can be a concern. An all plastic or all 316SS meter is the exception rather than the rule.

Front-end engineering and design: your best estimate
WEBApr 5, 2016 — Front-end engineering and design (FEED) is the phase of a project during which a percentage of the overall engineering required for a project is completed, with the purpose of developing a sanction estimate. Capital cost has a major bearing on return on investment, so the sanction estimate is an important part of the investment decision.
The move to electric boilers - Engineer Live
WEBDec 10, 2021 — Presser adds, “The move toward using industrial electric boilers is more than just an economic argument today. It is a significant, concrete way to meet corporate CSR commitments that move the company toward becoming carbon neutral in alignment with COP26 UN Climate Change Conference targets.

Pitting repairs in process vessels - Engineer Live
WEBAug 6, 2015 — Once pitting occurs a solution is then required, which should be able to satisfy three basic needs: (1) quick repair, (2) ease of application, and (3) rapid return to service. Additionally, the maintenance solution would ideally withstand service conditions for a considerable amount of time. Welding. Localised corrosion in the form of deep pits ...
What challenges are ahead for electrical engineering?
WEBOct 7, 2019 — Here, Steve Hughes, managing director of power quality specialist Reo UK, outlines some of the biggest challenges electrical engineers will face in the coming years. In 2018, we saw global EV sales surpass two million units for the first time; twice the amount sold in 2017. With the possible threats of catastrophic climate change and resource ...
