Hi
I have a question about where to take the water for desuperheater purpose. Attached you will find a schematic of 3 level control strategy for a water tube boiler and it is shown 2 cases:
Case 1
I take the water for desuperhetaer after the FT and FV for boiler feed water
Case 2
I take the...
Hi
To r6155. There were problems with the machine during the forming of the head. And problably will add some welding to the head to solve it but it will be so much welding additional
To david339933, the requirement as per client is 38mm. Values like 35 to 37 mm were taken. The manufacturer...
Dear georgeverghese
We have the flaretot.....relative to radiation height determinatio and so on, there are no problems. The thing is the detailed design of the SONIC FLARE TIP. I mean, how many exit points, mix air-gas for the best mix combustion issue, etc.....Once we win the contract, I...
Hi!
Currently where I´m working, I have already calculated the minimum thickness required as per ASME VIII DIV 1 and the minimum thickness is 38 mm and the plate thickness was for head forming was purchased in 1.625inches (41.275 mm). After forming, we checked thicknesses on the formed head and...
Hi!
I am looking for a engineer to contract as external supplier for the procesos design of a Sonic Flare tip (ir is for an elevated Flare) with múltiple exit points and variable capacity, I mean, a wide range of high pressure low flow to high pressure high flow.
Thanks

Hi!
I´m performing some static analysis on SOLIDWORKS SIMULATION but I have the following problem:
1.- The item is a section of a vessel and is going to be only under internal pressure. The problem I have is that if I use ASTM A36 (material precharged in solidworks library) I have results that...
Hi!
I have a Waste Heat Boiler with a steam production of 50,000 kg/h of saturated steam. I´m choosing to install 2 PSVs on steam drum. Regarding flow capacity, I cannot find the support of ASME CODE where indicates me that, I found on PG-67 BOILER, PG-67.1, the following:

Hi!
I try to understand one point from a UOP specification about FIRED HEATERS. We have a project for supplying 2 connected Fired Heaters (Fired Heater No.1 radiation box at the top will have a duct which will be connected to the duct of the Fired Heater No.2 but this connection is below of...
Hi!
I´m trying to calculate how much gas is required to burn 100% and destroy H2S from an acid gas. I do not know what considerations are required...I mean, if I need to achieve some temperature to destroy H2S or only having a combination of acid gas + helping gas and achieves a LHV of more...
Hi!
I have the following problem:
1.- I have an horizontal cylindrical vessel with following thicknesses in body and heads and nozzles: 3/4", 1-1/2", 2". Material: SA-516-70 Killed. This equipment will be PWHT performed. The vessel is completely welded (circumferential and longitudinal welds...
Hi!
Currently I`m trying to make an analysis in FLUENT 15.0 where I have a pipe with one inlet (12in diameter), a length of the total pipe of 10 ft, and at the end the pipe it has 4 pipes with a diameter of 4in. The fluid is air and I know flow and also I know the pressure at pipe inlet. The...
Hi!
I have already searched in ASTM the properties (Yield Strength, Yield point, etc) in order to see if a tubing of ASTM A513 can be used as support part in an enviroment where air is 220°C (428°F) but no results I found. As not only this tubing will serve as support but also as a road for a...
Hi!
I have the following situation:
-In the company where I am, It manufactures head vessels. I have a client that sent us a Purchase Order of manufacturing 30 tank heads (diameter of the head is 122.25 inches). The client supplied all material (plates of 1/2" thickness - 8ft x 40ft ASTM 572...
Hi!
I have the following situation:
I have a pilot which we added a flame rod (kanthal material)for detection flame. The flame rod is crown rod and the flame relay is the fireye MBPF-1001. The problem that I have is when we connect (belden wire) the MBPF-1001 to the flame rod "spark plug or...
Hi EdStainless,
According to drawing, it does not mention any particular composition. If the tubing meets standard carbon steel is OK. It is required just 2 items of 21ft more or less .
Thanks

Hi!
I´m trying to find a COLD DRAWN SEAMLESS STEEL TUBING for 2-7/8" O.D. 3/16" wall but no success. The USA suppliers that I have found, have just offered me the same size of tubing in DOM (DRAWN OVER MANDREL).
Can you give me a list of USA suppliers where I can get the CD SEAMLESS STEEL...
Hi!
bimr and LittleInch thank you very much for your answers.
@bimr and @ LittleInch
Attached you will find more details of dimensions, section cross áreas and cases. It is supposed that when you have the cap or plug totally opened, the Exit Q of wáter will be 20000 kg/hr.
As I close the cap...
Hi!
I have the following problema (see attached file)
On figure 1.0, you can see the system that is formed by two ítems, one of the is like a cap where it is going to be opened due to wáter comes to the system (see figure 2.0)
In external part of cap, it is a pressure of 2 kg/cm2g that has to...
