Piperack or Bridge design flow chart The process of designing a piperack or bridge involves a lot of consideration and co-ordination between different groups in the project. The major groups involve in the development of the piperack or bridge is layout, stress & structural. The initial study begins with layout group which gives the input in the form of 2D ...

Mass Flowmeter THERMAL MASS FLOWMETER CORIOLIS MASS FLOWMETER THERMAL MASS FLOWMETER Operates by monitoring the cooling effect of a gas stream as it passes over a heated transducer. Gas flow passes over two PT100 RTD transducers.  The temperature transducer monitors the actual gas process temperature, whilst the self-heated transducer is maintained at a constant differential temperature by varying the current ...

Flow meter is an instrument used for the measurement of the amount of liquid, gas or vapor that passes through them. In some flow meter the flow is measured as the amount of fluid passing through the flow meter during a time period (such as 100 liters per minute) whereas other flow meters measure the totalized amount of fluid that ...

<< Nozzle loads part 1 1.1         Proprietary Equipment Various Mechanical equipments like Pumps, Compressors, Expanders, Plate-fin heat exchanger, Air cooled Heat Exchanger etc. are classified under this category. Allowable loads for the nozzles of these equipments are generally available from equipment supplier. However, some of the proprietary equipment are designed and constructed as per International codes with standard set of allowable ...
