    dished end with small convex

    Perhaps if all fails can you do a proof test to determine its pressure limits?

    MWD/LWD

    Hi just curious- what is an international superintendent? What do you do? The best way is for your friend to introduce/ recommend you for an opening at his company. Why not? In this industry word of mouth matters a bit. Else look out for the job opportunity pages at the oil and gas service...

    Need help becoming a MWD

    MWD= Measurement while drilling, DD= Directional drilling/ driller MWD provide data while the oil well bore hole is being drilled such as direction the drill bit is going as well as depth, pressure, etc. Measurements are done by instruments that are part of the drill string, hence the term...

    Stiffener rings on horizontal vessel

    Hi Bobformoh, Some questions: What load is this and the direction it acts e.g. Blast load acting over a large area or point loads e.g a nozzle load? And how did you impose the load onto vessel for the LP Zick analysis? Thanks.

    pad thickness and material

    My reply is not replying why the re-pad should have the same thickness (local stiffness, etc), but why it is beneficial for the fabricator: I will have less steel wastage, because the pices from a cutting hole for a 24" mayway on the shell, I can use to reinforce a small nozzle on the shell and...

    3 Books a Process Engineer Should Read...

    Hello everyone, This question just comes to mind, because I am starting off as a process engineer in environmental engineering, and I am exposed to a lot of different processes- flue gas processing, steam and condensate circuits, etc. Can more experienced readers share book titles that...

    nozzle repad

    Well on a practical sense, the amount of heat from the weld you need to attach the re-pad can cause some distortion or the base metal to sink.

    pressure fabrication shop design

    A consideration for the future- beyond CS and SS: My previous company also did a study of welding more 'exotic' metals, e.g. titanium, tantulum, etc. For this you need a cleam room design, and we did have some priblems locating a space for it. But it was a no go due to low volume of jobs...

    A typical pressure drop for large silencers... ?

    Hi all, Thanks for reading this, I am a newbie in Silencers, and I hope for some pointers. Is there a 'typical' or rule of thumb value for pressure drop across a large silencer? It will be placed after an ID Fan, before the stack, with a maximum flue gas flow of ~100,000 Nm3/h. It is for a...

    Bag Filter Pulse Cleaning Air Quality

    I need some advice/ operating experiences on deciding the compressed air quality for the pulse-jet cleaning of filter bags that treats flue gases in a municipal solid waste (MSW) plant. The cleaning will be decided on the pressure drop across the bag. When the drop is high, compressed air will...
