Hi, Assume that the entity (A) is operating a gas pipelines grid of 900 km long at 50 kg/cm2. Gas is transferred to Another entity (B) at Dispatch terminal (DT), where B has compresser to take gas, at 50 kg/cm2, B transfers the gas to their pipeline network of 2000 km.. Flow is 120000 MMBTU...

Find the schedule number (40/80/XS...) required as per the design pressure/MAOP. Find the thickness of pipes in reducer in ASME B 16.10.

Thank you all for your replies. The pipeline is kept idle. But integrity assessment is need to be done. So we are going to do the ILI with gas venting. can anyone share me the excel file with formula & data input.

We have a 20 inch, 41 km of natural gas pipeline, which needs to be pigged by ILI tool. The pipeline has no gas flow. Hence pigging is planned by venting the gas at receiver end. The ILI vendor informed that the pipeline shall be filled to 15 bar, before launching the PIG. venting is planned by...

Hi all, I am working in Gas pipeline transportation, has cross country pipelines and terminals. I have below doubts 1) Is there any way to find the terminal pipe grade? any survey . Because in old terminals, pipe/bend materials used are of different thickness than the A333 or A106 Gr B. Also...

Thank you all for your response.

@Stressguy: Actually the pipeline was handling wet gas. Hence we wanted to do Integrity Assessment of this pipeline. @littleinch: It's CP protected. In 2019, DA Direct Assessment done. Found no external corrosion in ECDA. 04 locations dig verification done with metal loss of 6% in ICDA. MAOP...

Hi all, We have natural gas Pipeline laid in 1997. Pigging is done quarterly. API 5L X46 PIPE. Wall thickness= 4.36 mm. We have done the hydrotest of 4'' 2.61 km long in service natural gas pipeline. The test pressure kept as 15 kg/cm2. But the pressure started dropping, to reach 10.8 kg/cm2. I...

Hi Pumpsonly, We give the input speed in PLC, to get the required flow. 3 seperate VSD for each pump.

Thank you.

We are operating cross country LPG pipeline system. We have PRV, to reduce the pressure of LPG from 20 Kg/cm2 to 9 kg/cm2. But i feel that we can replace the PRV with Turbine expander, which will letdown the pr & produce electricity. Does my idea work...? Can someone help me in turbineexpander...

Thank you.

Hi BigInch, We have 2 filters(1+1)A & B, If filter-A DP is high, then take the filter-B in line.Isolate filter-A, and empty the LPG(@ 20 Kg/cm2, 1.5 MT qty) by flaring, thru blowdown line. I need a solution to extract this LPG from filter. Now my doubt is, can we push this LPG by high pr. water...

Thank you BigInch.

Hi SNORGY, In your idea, we have to input the flow & head to develop the curve using that CURVE EXPRT. am i right...? Hi BigInch, can i get the curve using PLC data...? if so, how..?
