I know of an expert who has handled 10 such storage planning commissioning deccommissioning in India. He may be of some help. you may try to contact for some useful tips. I am also trying to contact him, but he is in Doha Qatar for training programs on a relevant topic, Hazardous Chemical...
There shall be no problem even if you increase the pipe flow velocity to around 5 ft/sec. Rather, it helps to avoid any solids deposition. If the pipe length is small you may increase to 7ft/sec if you had faced the solids deposition as your operating problem. Do not oversize the pipe for such...
I had worked in a process plant which used sea water extensively as cooling water and then the process plant was salt based plant producing Soda Ash ( Sodium Bicarbonate).
We had measured the corrosion rates on Cast Iron and Steels. The sea water had around +28000 ppm chlorides. The atmospheric...
Try to use the PlantFLOW software by Bentley. You may visit www.bentley.com and see the list of software under plant engineering analysis. I have used this software extensively for similar work and for analysing fire water system of big process plant. My interest was also sizing the suitable...
If you mean the software used for modelling of plant P&I Diagram generation, layout, piping layout, etc then there are many competing ones like AutoPLANT, PDS, PDMS, EPLANT, etc.
You may visit few of their websites for more details
www.bentley.com, www.e-eplant.com,
Hope it helps.

I agree that the FEA is the choice when you do not have a proven design and stress analysis theoretical methods. FEA assumes lot of conditions and then arrives to the best stress distribution in the area of concern. However, it is prudent that we cross check such FEA with experimental stress...
I had worked in a Soda Ash plant and the liquids we handled were of similar characteristics as mentioned by you. Peoplew in the plan were using cast iron plug, ball and butterfly valves but with lot of maintenance problems. We started experimenting with Butterfly valve, nitrile rubber lined...
Have you heard of EPLANT- Piping, P&ID and STH for 3D plant design. this product is developed by RELSOFT Argentina? You may visit their site www.e-eplant.com for more details. The product is copmatible with AutoCAD 2000 and other recent issues. I am told that it costs reasonable. Give a try and...
Interesting. The replies of the experts indicate that for sea water carbon steel or lined carbon steel, stainless steel, FRP, PP, superaustenitic stainless steels, cupronickels etc are all used at one or the other place. Who says that SS 316 or 316L is not used in sea water service. All RO...
All the current and good software on PV design have the calculations done for you. You may try COMPRESS for the purpose and gives you all the calculation process in the reports so generated for the design of large openings in the vessels as per the ASME Sec VIII Code App. 1-7

The good engineering practice for petrochemical and chemical plants indicate that the deflection of the tall verticla vessel shall remain within 5 mm per meter which works out 6 inches for 100 ft. All good consultants for project engineering follow this criteria and it appears in their tech...
There are efforts specifically for the same purposes to refresh or help engineers to appreciate the salient points of pressure vessel design as per ASME Code Sec VIII Div 1. Some good correspond course through email issues are now available. you may visit the www.charismaglobal.com and view the...
Your boss can keep an evaluation mode MS Project valid for 60 days and use it for his viewing and if the activity is to prolong for more than that, he may purchase a license, which will not cost more than 600 US $.

The best and most acceptable material shall be carbon steel, and the pipe to specification ASTM A106 Grade A or B. I presuem that schedule 40 will be safe to be used.

I hope that the flow quantity is more related to the allowed velocity in the pipe. A water velocity of upto 10ft/sec in noncritical application shall give you the flow.
Generally discharge lines to pumps are designed with 6-8 ft per sec velocity for long distance transfer of water. Your inlet...
Interesting problem. It has been raised number of times and the same answer that shell become an indterminate structure once supported on more than 2 saddles. But cant we analyse the cylindrical structure supported on multiple supports? The calculation for stresses at mid section of the shell...
RT had been used since long as acceptable NDT for fabricated pressure vessels. UT was always used as complimentary technique to furthe investigate the defect sizes. The recent developments have brought UT at the forefront as the most reliable technique for defect evaluation. If you are aware...
Coming back to more authentic and detailed analysis, which is not easily possible manually, one may try WinNozl ( again Paulin software, marketted by Bentley, earlier Rebis). I have myself demonstrated the use in such trunion support cases and even for vertivcal vessel supported by pipe legs...
There is another very useful software which takes care of the buried pipeline. It is AutoPIPE Plus now licensed by Bentley ( earlier with rebis USA). The analysis takes care of the earth pressure, frictional longitudinal stresses imposed on the buries pipeline as it tries to expand due to...
May I get the contact website for procuring Australian Pressure Vessel and heat exchanger, Tank and process piping and pipeline standards. A similar help is needed for New Zealand Pressure Vessel and Piping standards
