In this blog article we are going to take a closer look at the API Standard 671 which specifies the requirements for special purpose couplings used in the petroleum, petrochemical and natural gas industries. This Standard has been developed by the American Petroleum Institute (API), which is not to be confused with the identical abbreviation used in the IT field (Application Programming Interface). Let's begin with a few details about the institute that gave the name to the API Standard.
When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some of your options specifically for cranes and hoists.
A virtually rotational-symmetrical component may have an unbalance caused by production tolerances or non-homogeneous structure in the material. Such unbalances in a drive system can not only lead to considerable vibrations during operation, but, in the long run, can also lead to failures of individual components or even of the entire drive system. As speed constitutes one of the decisive influences here, balancing is always performed for a certain speed. As a general rule, this is the nominal speed of the drive system.

Measuring processes unconsciously cross our daily paths more often than we are aware. Whether it is about scooping coffee for the coffee maker, the temperature of the coffee or the speedometer in a car - we encounter measurement technology everywhere. But, what is “measuring”?
A well suited definition is given here: “Measurement enables us to make statements about a measured parameter in relation to a unit of measurement”. Measurement technology allows the determination of parameters such as length, mass, temperature etc.
If buildings are shaken by earthquakes this can lead to cracks, instabilities in the support structure and in worst case szenarios to the collapse of the building. To efficiently absorb the enormous forces and thereby protect both, person and material, nowadays sophisticated technologies are available.
Not all damages that a great earthquake will cause can be avoided. However, with Friction Springs there is a very high probability, that the building withstands an earthquake – like those in Christchurch/NZ in 2010 and 2011 – and is still operational and habitable.
Since 1993 the annual exhibition and conference for the European energy industry presents new developments on the topics such as renewable energies, power plant technology as well as distributed energy generation. Since then the Power-Gen is deemed to be the leading trade fair for the power technology and energy industry in Europe, which takes place at changing locations every year. For the 25th issue of this trade visitor fair with its accompanying internationally oriented congress, organisers PennWell (UK) selected Cologne (Germany).
Who has not experienced the following? Arriving at the office in the morning and writing a to-do list, realizing at the end of the day that almost nothing has been finalized. There is always an additional, more important task or a colleague who needs a helping hand – faster, higher, further every day. The piles on the desks are not getting less. With a few tips and with discipline this can be changed. We have collected a few smart productivity hacks:
In a previous article we covered friction springs and their applications. This time we would like to explain the technical properties of a friction spring, how it works and why its features provide a variety of advantages compared to other damping systems.
Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 rpm to 15,000 rpm. Please see below which couplings are typically used and which are the selection criteria.
The presentation for the customer, performing at an exhibition or an internal meeting: again and again engineers have to face the challenge to present their developments. This isn’t everybody’s job. A frequent obstacle: preparing a PowerPoint presentation eats up time – and in the end it does not look that professional in many cases. The following basic tips should change that!
