    Piping Design after Superheater Header - ASME B31.1 Power Piping

    Hi All, I want to know your opionions/suggestions for my case. A supercritical boiler operating operates 260 kg/cm2; 570 C at SH outlet header, and we have 2 permanent steam blowing lines tapped from SH outlet header ends. Each steam blowing line is designed with 2 block valves (V1, V2)from...

    Permanent Steam Blowing design - Supercritical Coal fired boiler

    Hi, if one company decides to install permanent steam blowing line (blowoff line) to the atmosphere for Supercritical coal fired boiler (of course the steam blow pressure will not be the same as boiler operating pressure, the steam blow pressure would be 20% from boiler operating press). The...

    Permanent Steam Blowing design - Supercritical Coal fired boiler

    thanks Duwe, but i dont think so because it is blowdown/blowoff, what i am looking is the steam blowing. Shall i considered as steam piping (Boiler external piping, b31.1) since it is connected to the SH oulet header and the piping will have 2 block valves with piping and the block valves have...

    Permanent Steam Blowing design - Supercritical Coal fired boiler

    Hi, if one company decides to install permanent steam blowing line (blowoff line) to the atmosphere for Supercritical coal fired boiler. The installation is done by modifying the superheater header at each side. what are the related clauses for this steam blow line in asme section 1. thanks.

    ASME section 1, year 2011, table PW-11 volumetric examination, interpretation

    Hi All, Please share your opinion. can UT replace RT for tubes subject to furnace radiant heat with diameter below NPS 4 (DN 100) and thickness below 0.5 in. (13 mm). ASME Section I, 2011, table PW-11, general notes (g), requires thickness below 0.5 in shall be RT, while in the table for tubes...

    centrifugal pump code and standard

    @mical , i think all my questions i threw were in a polite sentence , and i said thanks to everyone for all the answers. Im a new member and considered my self as junior. I am sorry if my question is considered too easy or vague to you or artisi but i never force anyone to answer me. I think it...

    centrifugal pump code and standard

    I have tried google before ur comment. I think you are a cocky and not a "right to the point" person. If you dont have it just say you dont have it or just dont reply.

    centrifugal pump code and standard

    P@ artisi and everyeone , could you please share links free download hydraulic institute code for centrifugal pumps , and blowers and compressor. I only have API 610 , and i always use that. Thanks

    centrifugal pump code and standard

    Thanks All , @Artisi , the reason is that before project , contract shall be produced which may contain code and standard. Codes affect project cost.

    Pump cyclic applications

    Thank you all for sharing your opinions.. I think the motor S1 duty type is suitable for this kind of operation. I see same examples and the motor are still in good condition.

    Pump cyclic applications

    Hi thanks for responding , basically im asking can i run a pump cyclic with the conditions and specifications bove without really affect the pump motor life time? I see examples in industries that service water from service water tank that supply to service water pump and directed to the...

    Generator, PF, and reactive power

    hi All, I want to have your opinions about PF, and reactive power: 1) why does generator with PF 0.85 lag to 0.9 lead have better flexibility in the Grid than PF 0.9 lag to 0.9 lead? is it because they can work in lower grid voltage? 2) our grid regulating body requires power plant to have...
