Agree, the elbow fitting is altered; hence, it needs to be qualified. Yes, i have observed locations where fittings are altered, whether or not the fitting was qualified, i have no idea. Fyi, elbolets are made for this purpose.

pencwo, do not duplicate your postings, a site policy. best to keep posting in "gas compression" forum.

agree w/ LI. you won't find a code. consider this reference as a guide: https://wbdg.org/FFC/DOD/UFGS/UFGS%2023%2005%2048.19.pdf

are blowers in parallel operation with equal resistances in piping? if parallel operation, and pipe resistances/lengths to common outlet pipe are not the same, the motor with greater resistance may need the additional amps to overcome the increase head.

"pipeline has no gas flow. Hence pigging is planned by venting the gas at receiver end. . ." not feeding gas into pipeline at location where pig is inserted, your method will not work as there is likely insufficient gas to expand to push pig along the pipe.

"I'm sure the pipeline companies are going to reevaluate how they secure these valve stations near populated areas." Agree! in early 90's, my employer did this evaluation and resulted in some locations with block walls & others with bollards. In my travels about the usa, i have seen several...

"Has anyone else encountered F316L flanges with copper content?" NO any MTR that i reviewed and did not comply with the standard was rejected. "Is this a known issue with certain suppliers or manufacturers, and how have others in the industry handled similar situations?" Not that I'm aware...

all you need is steam temperature, pipe size, pipe length, & pipe wall thickness to determine heat loss. personal protection is more important; hence, insulation is applied.

to supplement LI post, i'm thinking something like a cyclone separator that is mounted in boiler steam drums. this would allow the "slag" material to fall out and allow steam to vent to atmosphere. however, this cyclone separator does not have a "target" per se. the "slag" material will...

to supplement previous posts, be sure of the appropriate pipe code. for gas pipeline transmission, B31.8 is the appropriate code.

sure . . . in a column, the tank level is the variable. in the adjacent column, the tank heat loss is determined. in the rows below the first tank level value, have the same formula in column for tank heat loss using the tank level in same row. continue calc for as many rows as needed.

after spending 8+ years in operations, i joined an EPC firm and never regretted it. my fellow engrs were outstanding and competent in their field of expertise. Yes, there was a lot to learn, but that is life. i made several site visits to resolve construction and initial operating issues. I...

the 2nd link works great. Thank you!

please verify the link . . . I get "Incorrect file path. Please check back to the site".

if there was a construction loan, the financial institution is liable. a construction loan should not be issued without the proposed survey/plot plan showing ownership. the financial institution, developer, construction company, etc. (all parties) should have obtained a proposed survey, plot...

replace tube. signs of excessive heat possibly due to poor circulation of fluid or direct flame.

Good observation! i suspect this is a typo and the ASME committee should be notified. Refer to page viii for interpretations. fyi, I've seen this before in AGA documentation which really baffled me for a month or so before i figured what transpired.

if you find an error, please report it to the appropriate ASME Committee as listed here: https://cstools.asme.org/BPVErrataAndSpecialNotice.cfm Thank you.

try posting in "Engineering Language/Grammar Skills" forum. not sure of organization, but student exchange programs are available.
