    Software for calculation of Insulation of Cryogenic tanks

    Dear iainuts, Thanks for your response. You're right normally cryogenics are below -150 C but here still as the Butene is in liquid form and also maybe client wants to call it so its called as cryogenic. I am looking for a software which can take inputs as parameters related to various...

    Software for calculation of Insulation of Cryogenic tanks

    Hello Everybody, We have a cryogenic tank which is housing BUTENE at -6.4 degree celsius. We have various insulation layers for the tank along with following technical data for the tank. 1. Tank diameter (inside) = 36.00 m 2. Tank height = 10.80 m 3. Liquid level = 10.50 m 4. Storage material =...

    Design and engineering of Perlite concrete blocks for Butene storage Tank

    Dear dhengr, Thanks for your response. Actually we have contacted the supplier but the problem is mostly they are NOT willing to share the design and mixing ratio details as they treat is sort of their own trade secret. They can supply blocks as per requirement but then to replace blocks again...

    HS-20 loading on a 3D space structure bridge grid

    Hi bridgebuster, Actually this project is related to a research project where we are trying to find out optimum usage of space structures as they have lesser weight and are easier to construct / assemble. I just wanted to do analysis to find out main forces and compare with some other models...

    HS-20 loading on a 3D space structure bridge grid

    Hi Bridgebuster, thanks for the response. Width is very less and is 2.4m. Length of one span is 6m. Right now i have modeled the frame elements (i.e. 3D truss) and the actual load will come on slab which will cover the 3d grid. But i am NOT modeling slab right now. So how can i apply the load...

    HS-20 loading on a 3D space structure bridge grid

    Dear All, I am working on a model of 3D space structure for bridge span. The space structure will ultimately support the bridge slab for taking various loadings. Structure is modeled in STAAD and the members are tubular with 2mm wall thickness and 20cm squares in plan. I have attached a model...

    Use of GPR (Ground Penetrating Radar) for buried pipe mapping in O & G Plant

    Thanks LittleInch for your insightful review. Can you please give some more information about CAT Scan and how it is performed? Also any info about supplier is appreciated. For me the major restriction is that it is a LIVE plant and by no means we can afford to do even a slightest mistake. We...

    Use of GPR (Ground Penetrating Radar) for buried pipe mapping in O & G Plant

    Thanks Ron for your quick reply. Actually we have mostly underground buried piping which consists of pipes for various utilities i.e. potable water, sewage water, contaminated water, gas lines, chemical lines etc. Most of these pipes are 6" dia or more and are spaced properly so hopefully...

    STEEL DESIGN

    Hi Kyut, Which version of STAAD are you using? If you're using STAAD.Pro v8i then surely it has a utility of CONNECTION DESIGN and it's really an excellent utility for 3D connection design. It has intuitive interface as well as tutorials in the help menu.

    Underwater Grouting Works - Offshore

    Dear Ingenuity, Thank you very much for sharing your experience. I have one last question before I prepare my final estimation and quotation for client. I'm bit confused regarding exact mix-design. Should I use some proportion of coarse or fine aggregates for my final mix design or is it OK that...

    conc. crack sealing

    If you want to seal wet cracks (leakage injection) then you can use a combination of Nitofill UR63 (70%) / Nitofill WS60 (30%) and both these products are from FOSROC. To seal DRY cracks you can use Nitofill EPLV from Fosroc. Equivalent products in BASF are Concresive 1320 / 1335 for wet cracks...
