Can anyone tell if PV ELITE considers pipe undertolerance while performing WRC calculations for nozzles?
When I run the analysis, it does take the pipe undertolerance while performing internal pressure calculations for nozzle, but for WRC, I saw in the report that the software has mentioned...

Can you please elaborate on the problem of inspection and ultrasonic testing in case of skirt support on a small diameter cylinder @r6155
thread794-274496
Does anyone have an idea what does briggs mean??
This is a std dwg of a reinforcement pad in which there is coupling coming out of a reinforcing pad and it says that this arrangement is reqd only in case of insulated vessel
At the top of there is a 1/4" npt and at bottom there is a 1/2 coupling...
I was reviewing calculations for vertical vessel on skirt support.
In its report generated from PV ELITE software, in the summary table, for the skirt, it lists required thickness of skirt as "No calc"
Although the thickness used in calcs for skirt is 10mm
Does PV ELITE not calculate the...
Can cladding (316L) be applied on SA 105N flange or is weld overlay of 316L a better option??
There is a cladded vessel and the vendor is taking cladded plate for the shell(material SA 516 70) but for flange of SA 105N, vendor is applying a weld overlay of 316L.
So, is cladding possible of a...
Can anyone elaborate this clause of UCS-56
"Above 800°F (425°C), the rate78 of heating shall
be not more than 400°F/hr (222°C/h) divided by the
maximum metal thickness of the shell or head plate in
inches"
What does it mean by "divided by the
maximum metal thickness of the shell or head plate...
There is a vertical vessel supported on leg supports
This vessel is a tall vertical vessel and its height is about 11 ft – 8” diameter. This is made of 8” pipe. It is supported on 3 legs made of angle iron. (Total vessel height 3 meters and legs height 1.5 meters)
The vessel under strength...
Hi everyone
I am writing this post with regards to a problem being encountered with one of the safety gaskets in automatic hot rolling mill stands.
Are there any rolling mill engineers here so that I may explain the issue in detail??
Hello,
I am writing this thread regarding a problem I am facing at my work. I am working in a steel rolling mill. Our quick release couplings being used for air oil distributor on rolling stands are made of stainless steel. These stands are water cooled for avoiding the roll pass from excessive...
Hello,
Can anyone here guide me regarding material of a vertical submersible centrifugal pump required to handle sour water service (H2S and NH3. The following are the process conditions
Capacity rated: 25 GPM
Suction pressure Max/rated: 10/0.01 PSIG
Discharge pressure: 27 PSIG
Discharge head...
Hello,
I just want to ask any process engineer as to what would be an appropriate sizing for a horizontal pressure vessel, to be put in a pit, having a nominal volume of 6.7 cubic meters.
Operating pressure : 5 Kpa
Design pressure : 3500 Kpa
Corrosion allowance : 5 mm
Specific gravity of...
Hi all,
Can anyone tell how do the statuary regulations govern the design or fabrication of static equipment like heat exchangers and pressure vessels?
Hi all,
As per UCS 66 (b)(3) "When the minimum design metal temperature is colder than −55°F (−48°C) and no colder than −155(−105°C), and the coincident ratio defined in Figure UCS-66.1 is less than or equal to 0.35, impact testing is
not required".
My question in this matter is that, if for...

Hi everyone,
Please tell a thumb rule for the selection of a roof type (self supported, rafter supported, rafter+column and dome) based on the diameter of a storage tank being designed in accordance with API 650
As i have read, the storage tank guide book by Bob Long gives the following...

Hi,
I am reviewing a quote from vendor wherein he has mentioned the following two types of materials for the "plate" of a plate heat exchanger.
(1) Ti Gr1 SB265 easy clip
(2) Titanium ASTM B265 grade 1 paraclip
The sevice of both is "vat liqor".
I want to know what is "easy clip" and "Paralcip"
Hi all,
The thickness of a skirt supported is only checked in compression against the induced wind moments and not against tension. But, the side of the base plate, which will be in tension, will try to overturn, which will be resisted by the anchor bolt. But, then, we need to evaluate the...
