Hi, The client has asked for a thermal bowing analysis for a thin walled insulated steam line. The client wants to investigate if thermal bowing occurs and if it is occurs what stress are developed in the pipe when the line is warmed up during the winter time, when the ambient temperatures can...

Hi, I have run a structural analysis to investigate the Circumferential, Radial & Axial Stresses in a pipe wall. In the stresses output results, there are listed several types of stresses(Von Mises Stresss, Principal Stresses and Tensor Stresses). Which of these do I need to look for in order...

I have to determine the thermal stresses in the wall of pipe, during the start up/warm up of 18 inches and 12 inches with 8 inch and 7.5 inch insulation thickness steam lines. The length of the lines is about 190 feet and consists of a few bends, two Wye Tee fittings, pipe and insulation. These...

Hi, Are centrifugal pump nozzle loads solved for the operating temperature or are they solved for the design temperature? In my piping stress model I have defined the design parameters as T1 & P1, and the operatin parameters as T2 & P2. The pump is a centrifugal In-Line Vertical pump. Any...

Hi, I have run a pipe stress analysis for a piping system which carries condensate to a condenser. Two of the lines (NPS 4 & NPS 6) are piped to a surface condenser. The lines run through the condenser shell(3/4" thickness). They are welded on both sides of the surface condenser and run a few...

Boghi1990 (Mechanical) 9 Dec 11 1:30 Hi davefitz, I have several drain lines piped to a flash vessel. The drains are collected into 4 manifolds. Superheated steam flows through these drains. Sonic velocity(choking) occurs at the end of the drains. I am trying now to size the manifolds. I was...

Hi, I am trying to size a flash tank. There are 19 drain lines (sizes varying from 3/4" to 10") coming into the flash tank. From the flash tank there are a 3" line and a 6" line running to a condenser(pressure in the condenser is 1.5Hg inch, vacuum). Is anybody out there who knows what...

Hi, Why the suction and discharge lines have to be one or two sizes larger than the pump connection nozzles? What could happen if the suction or discharge lines are larger than the pump suction or pump discharge nozzles? I would appreciate if anyone can help me with an answer to this topic...

Hi, I do not have too much experience in piping design.I would appreciate if there is anyone out there who could give some advice on the following questions. Regards, One Point "When the centrifugal pump is supported by piping, pipe supports should be installed on both sides of the pump as...

Hi, A 24 feet dia, and 40 feet cone shaped roof uninsulated storage tank, filled with 80% crude oil. The fluid in the tank is stationary and the tank is exposed to ambient air. The intial mean temperature of the crude oil in the tank is 20C.The data available is the daily min. and max...

Hi GBor(Mechanical), Is there any basic guideline which can give an idea on what would be the appropiate mesh size when one starts meshing a CAD model imported into Algor? The same question if the mesh is created manually in Algor FEA editor ? Is the mesh size dependent of the actual...

Hello, I am seeking for some material/documentation which can help me to set up a list of procedures and guidelines for Algor modeling and analysis. Looking forward to getting some tips and advices. Kind Regards, One Point
