Mar 12, 2009· First of all the main reason there is a reducer in a pump suction line or a pump discharge line is because the pipe line size is different from the pump nozzle size. The process engineer determines what line size is required for all lines to perform the function of the process. This is true for both the suction and the discharge lines for pumps.

Mar 03, 2019· 1) The "compressor suction low pressure alarm" of A0101 and A0102 caused by the wrong connection of signal cable. 2) System vacuum is not clean, caused the discharge pressure is higher when A0101, A0102, A0103 are working and stop. 3) A0103 running suction pressure is lower, caused by the blocked system pipe.
AC corrosion is unpredictable for AC current densities between 20 to 100 A/m 2; (~ 1.86 A/ft 2 to 9.3 A/ft 2) AC corrosion typically occurs at AC current densities greater than 100 A/m 2; (~9.3 A/ft 2) Highest corrosion rates occur at coating defects with surface areas between 1 and 3 cm 2 ( 0.16 in 2 – 0.47 in 2) AC Corrosion
Dec 04, 2009· One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube. The capillary tube is made up of copper and it has very small diameter ranging from 0.5 to 2.28 mm (0.020 to 0.09 inches). Capillary tube used as the throttling device in the domestic refrigerators, deep freezers, water coolers and air conditioners.
loss of the whole system. For the suction side, you can also use the same size pipe as the pump suction connection, often one size bigger is used (ref. tutorial3.htm). A typical velocity range used for sizing pipes on the discharge side of the pump is 9-12 ft/s and for the suction side 3-6 ft/s. 13. Pressure at high point of system
Jul 02, 2013· As promised (I’m back from vaion), this post will discuss Liquid Lines. But before I do, I forgot to mention something during the discussion on suction lines that also applies to liquid lines. When we talk about pipe sizes like 1-5/8 inch or 2-1/8 inch or 3/8 or 5/8 we are always talking outside diameter of the pipe.. I’ll give you this little way of how to remeer this and …
suction delivery hose. The suction delivery hose is suitable for conveying powder, grain, water and oil, etc. in the industry, agriculture, irrigation and civil engineering. It is the ideal alternative for rubber hose and metal pipe. To be light in weight with good resistance to the hard weather conditions and minus pressure, and small bending

Oct 13, 2008· Page 1 of 2 - Pump Suction Piping Rating - posted in ChE Plus Forum: Dear All,In many projects the piping class (Rating) of pump suction (especially from pump suction block valve to suction) is the same as pump discharge line.1- What is the reason?2- Does any criteria exist for this matter or we should do the same for all systems?Regards,Mehdi Orojlu
Jan 15, 2018· The suction line consists of Lt=15 m of straight tube with 8 long radius elbows while the discharge line consists of 15 m with 10 standard elbows. Then, determine the lines’ sizes if the condensation temperature becomes 50 °C. Suction From Figure 2, 191.84 kW capacity in 54 mm OD suction line results in a 0.04 K m-1. Thus, from Figure 3, a 50 mm long radius …
Side Suction Side discharge pump piping-“Arrangement K1”. “Arrangement K1” is for Side suction and side discharge pumps. If the line size is bigger the elbow on vertical can be omitted and the whole valves can be arranged in ground level, this helps in supporting also. The routing for vertical pumps is shown in below “Arrangement L1”.
Suction pipeline design The root cause of many pump problems and failures can be traced to poor upstream, suction-side, pipeline design. Common problems to avoid are: Insufficient fluid pressure leading to cavitation within the pump. Narrow pipes and constrictions producing noise, turbulence and friction losses.
