    Slug Catcher Design Companies

    Anyone have suggestions on a good company for engineering slug catchers? We have a slug catcher made by a company which is not working for our operating conditions. The manufacturer for it seems unwilling to help, so we want to have another company review the design and give modification...

    pump pressure variables

    Does anyone have ideas on how to reduce pump outlet pressure? We recently installed a pair of pumps (primary & backup up operation) which are delivering 80 psig pressure where we were expecting about 50-60 psig. I'm not sure why it's building that much pressure, but need to know ways/ideas on...

    Online Source for Equivalent Lengths of Pipe Fittings

    Does anyone know a good source on the web for accurate equivalent lengths of pipe fittings. I have searched & located several sites, but they all seem to vary significantly & especially compared to sample values in my mechanical engineering reference manual. I especially want to know the...

    WPHY meaning

    Does anyone know what the acronym "WPHY" stands for in regards to pipe fittings? From my research it appears the the "HY" stands for high yield (strength). If that is true, then what about the "WP"?

    GE Frame 3 Starter

    Has anyone ever replaced the starter for a GE Frame 3? We have several of these units at a couple of facilities. They were initially installed with Elliott Steam turbine starters (circa 1960's). Some of those steam starters were replaced with Coppus gas turbine starters in the 90's. We are...

    Regulator Trim

    Really basic question here: can someone please explain what "trim" refers to with regards to regulators? And, is it the same as the percent capacity?

    Typical EGT for I.C.E.'s

    can anyone tell me what typical exhaust temperatures (at the header) would be for a 4-cylinder normally aspirated, gas-fired engine. secondly, what about that same engine with a factory turbo installed? (e.g. mitsubishi eclipses 1990 - 1999 models, lancers,.. ) would there be a dramatic temp...

    wall height for SPCC

    Does anyone know if there is a minimum height requirement for a concrete wall secondary containment for AGHST's? I have read that the containment volume should be adequate to contain the volume of the largest tank plus have sufficient freeboard for a 100 year storm event (for a 24 hr period?) &...

    fire code issues with UL 142 tank

    I recently placed an order with a tank manufacturer for a UL-142 AGHST with a site glass. In replying with the shop drawing (for approval) he wrote the below message: "we did not list any openings for a sight gauge on this shop drawing. It is not recommended to have openings below the liquid...

    L.O. Tank internal coating

    does anyone know if a horizontal, aboveground, lube oil tank at atmospheric pressure needs an internal coating? or is this something that is done as a "best practice"? is there a spec which requires this coating (or corrosion allowance)? if so can someone tell me what it states? thanks, kgj

    need help determining height for elevated tank

    i plan to install an above-ground, lube oil storage tank. the client wants this tank to be elevated high enough to tie into an existing oil header line without using a pump (i.e. gravity-fed). The planned setup is: a 2000 gallon tank will be located outside; approximately 40 feet of 1"...

    determining pressure drop across valve

    i need to determine the max volume (capacity) of nat gas across a couple of valves. this seemed simple enough, get the valve constant from mfg and plug into eqn: Cv = (Q/1360) * [(2*G*T)/(deltaP*(P1-P2))]^0.5 i contacted one mfg and got their valve constant, but the other mfg (Grove) told me...

    Help with Relief Valve Capacity Calculation

    how would i calculate the capacity for a piece of equipment which has a MOP of 800# and it's MAWP is 110% of that - 880#. the relief valve is set for 850#. from API 520, the total relieving pressure equals set pressure + 10% of set pressure + atmospheric, then obviously it would exceed the...
