Dear All, Can anyone inform me on available level sensing devices in the market, acceptable to TDP-1 that can be used on drain pots at high temperature&pressure applications . I understand float type level switches may not work for 1800 psig, 1050 deg F high pressure steam for example. Is...

Dear all, I would like to get your comments to the following: ASME B31.1 mandates that downstream of a pressure reducing valve shall be protected either by i)designing the low pressure side same as high pressure side ii)or by installing a pressure relief valve with sufficient capacity. Now...

Dear All, I would appreciate if anyone can shed some light on the following issue: We are designing boiler external piping and non-boiler external piping per ASME B31.1 code. In this code there is reference to ASME B16.34 as the only applicable valve standard. However in the market most valve...

Hi all, Can anyone point me in the right direction as to how I should approach below problem I am facing: I am designing a pumping system where condensate transfer pump discharges water directly to boiler feedwater pump in a power plant with no tank in between. (My condenser is deaerating...

Dear All, Can anyone submit comments to my original thread1203-200194 posted in Safety Relief Valve Engineering forum. Regards ProcessEngineer

Dear All, I am in the process of developing a spreadsheet and would appreciate help on the following topic: In case of a high pressure safety valve, say boiler superheater PSV, the flow is choked at vent exit as well as at PSV nozzle opening just like in the example given in Nonmandatory...

Hi everyone, Can anybody shed some light on why no API 5L pipe material is allowed in boiler external piping? Thanks

Hi, I would appreciate if anyone can clear up my confusion about the following subject: We know that during the transformation of austenite to pearlite, nucleation and growth of alternate plates of cementite and ferrite occur within austenite grain boundaries. Are the cementite and ferrite...

Dear All, When sizing the safety valve vents in power plants, I use the equations given in ASME B31.1 Appendix II. According to the calculations, it seems that for 99% of steam safety valves common in the market, the valve exit pressure is too much (since the SV nozzle as well as the vent tip...
