    Can we have Nested Loop IF, have more than 7 times?

    Thank you very much people, you are all very helpful. I was devastated by the Katrina hurricane so I couldn't reply anyone on time to thank for your time. I will now face again another disaster, Rita. God Bless!

    Can we have Nested Loop IF, have more than 7 times?

    Nesting level limits indicated a formula can contain up to seven levels of nested functions. Is there anyway I can loop more than 10 times because I am calculating a loop for 10 different sizes of pipeline for the gas loss calculation. Can someone please help because this is very critical to be...

    Estimate methods for Major Refinery Turnaround

    Wow, thank you my friend for sharing opinion. Let me ask anyone who read this post. How would you break down a project estimate manhours. Would that be best like this: Engineer hours (mech/e&i) Design hours (piping/e&i) Project Management hours Construction supervision hours Please give me...

    Estimate methods for Major Refinery Turnaround

    Dear friends, My boss threw at me a huge projects and told me to do an estimate. What should I do now, go and get drunk or start to do work breakdown structure into disciplines? What would your best approach to quickly start on this Fluid Catalytic Cracking Unit Turnaround estimate prepared for...

    ASME SECTION VIII Div. 1

    You offered very sincere helps. You are right about the repad, the 10" nozzle already had its repad. If we have to remove that repad and replace with 12" repad, that will be very difficult but the vessel engineer told me that the 12" nozzle with LRFWN won't need a repad so I don't know if we...

    ASME SECTION VIII Div. 1

    Brian, Thank you so much for your advice. I am trying to do the nozzle calculation but how about the hoop pressure since we are enlarging our opening from 10" to 12", is that means we are going to lose some metal and weaken the drum? Again, thank you for your time and concern.

    ASME SECTION VIII Div. 1

    If anyone can assist me to determine what UG for reference and I can look up ASME Section VIII for calculation, I just want to make sure by opening the inlet from 10" to 12" on the specs given would still within codes, and it needs to show on calculation. Thank you very much.

    ASME SECTION VIII Div. 1

    Dear Gentlemen, This drum is service for Fuel Gas, called a Fuel Gas Knockout Drum. The material is Carbon Steel (A-53). The drum is horizontal type and our goal is to reduce the inlet flow which located on the top near the end and the inlet located the bottom of the opposite end. Does anyone...

    ASME SECTION VIII Div. 1

    I have an old Drum (1943): Dia = 8'ID Length = 30' Test Press =195psi Op Press = 70psi Temp = 100F Corrosion Allow = 3/16 Thickness of Head =13/16, Horizontal Cap = 12,000 Gal. According to our calculation, I have pV2 = 9,000, we are trying to reduce less 2,700. Process Engineering recommended...

    Expansion Joint Calculation for Oil Refinery Piping Process

    I was hoping you would have something in Br. Units instead of Metric. Thank you.

    HOW TO Reduce flow on the inlet?

    To make my question sample, I would like to ask you: would converting from 10" Nozzle to 12" Nozzle on the above specs affected the Drum's Vessel Code? Thank you.

    Expansion Joint Calculation for Oil Refinery Piping Process

    Thank you very much, I am reviewing the website you indicated and read them carefully. I just hope you might have information on slip on also. Is the bellow type more useful in refinery application? Thank you.

    Challenge: A216 Gr WCB to meet Stainless Steel ?

    Groberts, That is the exact answer I am looking for. Thank you very much. You are on the right track, but could you be more specific about MRO1975. Stanweld, Thank you for your explanation about the welding procedures for heat treatment.

    Challenge: A216 Gr WCB to meet Stainless Steel ?

    Can we heat treat A216 Gr WCB to meet Stainless Steel NACE requirement? If we could heat treat, what type of heat treatment or temperature do we require to perform? Please give me a detail answer. Give me an oppotunity for this rookie to shine herself...hihihi....
