DRG is delighted to announce the Fastest modeling tool of piping systems: ISOtracer® v.1.0. Based on isometric drawings, ISOtracer will save the pipe stress engineer up to 50% valuable modeling time and costs. In ISOtracer the user automatically builds a 3D model by clicking along the routing instead of manually inputting every pipe element. The generated 3D piping model can be directly imported in common pipe stress software CAESAR II, Autopipe and Rohr2.

October 5

The importance and methods of assessing unbalanced loads on piping systems related to slug forces and surge/waterhammer events.

Time:4pm CEST (View your local time)
Duration:30 min.
Cost:free
Presenter:ir. Edwin Schimmel (Project Engineer)
  • This field is for validation purposes and should be left unchanged.

Shock loads such as surge/waterhammer, slugs and pressure relief loads can impact a piping system. The pipe stress analysis program CAESAR II has a dedicated Dynamics Module for accurate analysis of stresses due to these load types with inclusion of the dynamics effects. Calculation of the magnitude and time-variation of surge/waterhammer forces can be calculated using the BOSfluids software and directly exported to CAESAR II.

Two popular methods exist for the analysis of shock-type loads. These are the Spectrum Method and the Time-History Method. The webinar will demonstrate the generation of dynamic force input values and the use of both assessment methods and also explain the differences between the two.

Fiberglass versus steel piping: engineering differences and FRP allowable stress envelopes.

  • This field is for validation purposes and should be left unchanged.

This DRG Webinar will cover differences in the engineering process of steel piping systems versus Glass Reinforced Plastic (GRP) piping systems. Both types of material have separate (dis)advantages and properties. For GRP the material properties are also different for the hoop and axial direction. This results in different approaches in the applicable design codes and deviating engineering knowledge is demanded. Also FRP failures manifest differently with respect to steel.

The GRP stress allowable values are provided by a stress envelope (hoop versus axial) rather than a fixed value. The different aspects involved to construct the GRP design envelope according ISO14692:2002 will be provided. Construction of design envelopes for GRP piping often leads to confusion. This is caused by fundamental differences in the piping properties with respect to steel and the different methods provided in codes.

For example, in contrast to the DIN code the ISO code does not apply a constant factor (x6) to obtain the long term envelope from the short term envelope obtained from burst tests. However, it used long term regression testing and qualification to obtain the GRP design envelope. This DRG Webinar will cover both theoretical backgrounds and practical issues related to projects performed by DRG in the past.

December 7

Fatigue assessment according ASME VIII Division 2.

Time:4pm CEST (View your local time)
Duration:30 min.
Cost:free
Presenter:Dr. ir. Frank Bos (Project Engineer)
  • This field is for validation purposes and should be left unchanged.

Pressure vessels like heat exchangers are often subjected to cyclic loading (temperature and pressure). Therefore a proper fatigue assessment according to ASME VIII Division 2 is required. This webinar provides an overview of analysis and design methods for welds subjected to fatigue loading. Special focus was given to welds typically found in pressure vessels and piping.
