The pipe stress is slightly higher at ratio of 1.05 times the allowable in sustained case. Since the factor of safety is 3 in B31.3 piping code, is this wrong way to analyze the pipe? Due to constraints in space, it is really difficult to input any supports and the cause is due to low axial...
Pressure in pipes during operating condition is full vacuum. How do we input the pressure value for pipe stress analysis? Should it be zero Mpa or we should use atmospheric pressure?
Hi,
Good day.
I'm currently searching for standard dimensions of an insulated pipe support, like U-band support over the polyurethane insulated pipes. But I cannot find it at all. Most of the dimensions I get are from the Japanese manufacturers only, which is not useful to me. I do not know...
Dear everybody,
I've been working in a company for more than 2 years as a piping engineer in Japan.
My company does EPC works of incineration plants.
Most of my works is to do pipe stress analysis. But the incineration plant only has around 12-13 lines. Over the time I have learned how to use...
Can anyone explain what is the meaning of tie rod gaps provided by the manufacturers?
What happens when there is no gap in either one of forward or backward direction?
What happens when there is no gaps at all? If there is no gap, will it help the piping system in reducing axial load? and how...
Hello Everybody,
I want to know the difference between elbows and bends.
I have found information like strength, friction, pressure drop, etc of using them but I want to know from manufacturing point of view and cost wise, which one is more economical?
If space is not a problem, is using bends...
