About fl**ge bolt load under internal pressure

Most engineers believe that the bolt load will increase if internal pressure is applied to a fl**ge assembly with an internal bolt circle gasket.

This video demonstrates that it can be the opposite, the blue elastic bands are representing the bolt (load): https://vimeo.com/340844165

The first part shows the misunderstanding, the second part shows the interaction of the result of applying the internal pressure and the flexibility of the fl**ge hub with fl**ge ring. This gives a different meaning to the m and y factors used in the Taylor Forge method and a different view on the effect of the loads during assembly, test and operation/design conditions.

If you are in doubt of the leak tightness of your standard or custom fl**ge assembly, use the EN 1591-1 calculation code, or contact us, or red-bag.com.

Most of us think that due to internal pressure the bolt load will go up. However it is the other way around. Due to rotation around the gasket the bolt load will…

Online Master's Degree on Rotating Machinery (5th Edition)
We are delighted to announce the fifth edition of the online Rotating Machinery Master’s Degree organized by InIPED from September 2018 to July 2019.
The previous editions of the program attracted a lot of attention involving together more than 100 participants from all over the world.

The most relevant features of this program are:
- The teaching methodology employed is "problem based learning", which places great emphasis on learning by applying the theory to solve a real-life problem related to turbomachinery.
- We make extensive use of web conferences to give the students the chance to interact with the instructors.
- The instructors have been carefully selected from different backgrounds: industry, university and manufacturers. This guarantees real world study cases and up-to-date knowledge coming from people who are working in this field.

The program is mainly aimed at:
- Rotating equipment engineers
- Maintenance equipment engineers
- Mechanical Engineers or other specialities focused on turbomachinery
- Graduates interested in getting deep knowledge in Rotating Equipment.

Application is open until March 31st, 2018.

Turbocharger vs. HPRT: energy recovery applications in Oil&Gas Industry

Teijeiro, Beatriz

In the past, most of the Oil&Gas industries used conventional pressure reducing valves to suit to downstream process conditions. Therefore, a big amount of hydraulic energy was dissipated and wasted. Hydraulic Power Recovery Turbines (HPRT) were developed in order to convert this pressure into mechanical shaft energy and increase the overall process efficiency as first step in the energy use area. Nowadays, HPRTs are being substituted by turbochargers. This new rotating machinery is mainly used in Chemical Plants and they are under development by several manufacturers in the Oil&Gas Industry. The main goal of this workshop is to follow selection criteria of these machines (either HPRTs or Turbochargers) highlighting advantages and disadvantages of both options in the same process application.

Engineering procedures in Hazardous Atmospheres in Power Plants
Rubio Martínez, Ana

Hazardous atmospheres are one of the non-visible components of a facility. Dealing with them in the right way is not easy because of their physical and chemical properties and the needed of knowledge about their extension and location in an early stage of the project. The presentation shows some deadlines and strategies of some working procedures to help to optimize costs and avoid safety problems.

Evolution of Gas Turbine Combustion Systems to DLE Extending Fuel Flexibility

De la Fuente Ortiz, Jesús

Demand for higher gas turbine fuel flexibility with reliable combustion systems is becoming a decission making factor in several applications accross the power generation and Oil and Gas Industry when selecting turbomachinery. During this exciting workshop I will share the latest developments in dry low emission technology with non standard gaseus fuels and dive into specific cases where burning process gas helps refinery, petrochemical or upstream operators avoid flaring and capitalize such gases generating power, while matching highly stringent emission requirements.

Thermoplastic labyrinth seals to reduce leakage in centrifugal compressors

Metz, Kolja

Thermoplastic labyrinth seals offer the possibility to reduce the internal leakage flow over the cover disc of closed impellers in centrifugal compressors. The efficiency gain compared to traditional metallic labyrinth seals mainly depends on differential pressure and sealing clearance. The presentation shows the results of development and testing of thermoplastic labyrinth seals, which are fully interchangeable with previous metallic seals. A seal design for integrally geared centrifugal compressors is introduced and the calculation of optimized sealing clearances for different operation conditions is shown.
