Dear all,
In a ruuning plant, we would like to determine the actual loads imposed by the piping system on the nozzles of one pump. We do have a piping stress model (Caesar) but are interested in measuring the actual loads during operation, not using simulation, FEA, etc.
Any of you is aware...
Dear all,
I'm involved in the checking of a pipe cross of 60"x48" in a cooling wáter line subject to B31.1. The intention is to fabricate it as direct branch connection with or without reinforcing pad. The thing is that in the past I've used B31.1 indications (section 104.3) for TEE...
Dear all,
I need to perform a calculation of the flow by gravity in a not full pipe. I used in the past Manning equation for that purpose with water pipes, but this time the fluid is diesel oil. I am not sure of the correction to be done in Manning equation, since I guess that diesel viscosity...
Dear all,
This issue has been previously discussed in this forum (thread794-212082) but there is something not clear to me
In B31.1 Appendix A, Note 1 indicates that "THIS MATERIAL IS NOT ACCEPTABLE FOR CONSTRUCTION OF PRESSURE RETAINING PARTS OF BOILER EXTERNAL PIPING — SEE FIGS.100.1.2(A)...
Hello,
I am trying to find some guidelines about the required analysis of the makeup water to boilers.
I know ASME or ABMA ones but they refer to the boiler feedwater or the boiler water, but not to the makeup water. Additionally I use EPRI TR-113692, but it doesn't make any difference for the...
Dear all,
I'd like to get your kind advice about the installation of suction heaters vs heat tracing in the following case:
It is a 24000 m3 LDO tank, whose pour point is -9ºC and it must get to the transfer pumps at a minimum temperature of 10ºC. The minimum ambient design temperature is...
Dear all,
I am trying to determine whether a water pipe in a cold climate can freeze even if the line is in operation continuously.
I understand that the water in a pipe not in operation (no movement) gets frozen quicker than the water in a pipe in operation (it's circulating) but I can't find...
