Hi Gents Load is vertically down. A panel will be bolted to a cross beam welded to the vertical stand.

Thanks you mate. Appreciate the help. Just for my further understanding, which source / book do you obtain the formula.

Hi All This may sound very simple to many. Not exactly my field. I wanted to bolt up (4 bolts) from a vertical plate to an existing beam. Please see my attached sketch. I intend to mount a panel on the stand which is about 80kg (including the the stand weight) Bolt/stud is M16 grade 8.8 or...

You need to consult the material specialist for the appropriate material for the tubes. My Amine (sour) service HE uses ASTM249-304L. Seems okay for our process. For the shell, I think CS with the appropriate coating would do the job. We uses AS1548 but with 409 overlay on one of the nozzles...

Hi All Has anyone in this forum had used polyuria on a oil tank? Any pitfalls or drawback? Fixed roof and/or floating roof. I have used them before on a Sandfilter tank (water). They are generally very good is applies properly Thx in advance

Hi All We normally used Aluminium (or Aluminum) Bronze for the bushing of our cooling water (sea) butterfly valve. We have a proposal from a manufacturer using Copper instead. The EPDM seat separate the service product from the bushing. Just want to get any feedback from users out there who...

Hi All Thanks for the prompt reply. We will break and remove the refractory inside the vessel where the shell shall be cut. FYI, anchors are welded onto the shell to hold the refractory. (After the new shell welded, will reinstate refractory). I have attached another diagram below. From my...

HI All I am planning to do a shell repair on a refractory lined furnace. Bottom section of the furnace will have the refractory removed and shell cut out. My concern is that do I need some kind of temporary structural support when the shell is cut out. Mind you - Refractory on the other part...

The only time I had to replaced a valve with the valve open was a water line. It had a about 20 meters of head (residual). Too much pressure on one side, though it can be operated. But not easy to pull out the valve. Didn't want to drain the whole header as well (would take about 1 hr from...

I would think that valve sizing (including relief) is more of the Process Engineer role?

Hi All I know a bit about corrosion but I am no expert. This one has been troubling me a bit. While I was working in a mining site many years back, I had encounter a problem with galvanic corrosion in a filtration tank. It was repaired but I still trying to understand the corrosion process...

Hi All I;ve attached a schematic of it.http://files.engineering.com/getfile.aspx?folder=2c9c44bd-abcf-4572-8f01-60d19bbcc98c&file=Gap_between_pipe.pdf

Hi All I am doing a line stop on a 10" low pressure steam line. Steam pressure of 200 - 300 kPa. Temperature of 150 degC. I will need to weld in a split tee to accommodate the line stop equipment. It will be an encasement of the pipe by the split tee. It will be hot tap to allow for insertion...

Hi I would have thought that the process safety engineer would provide that answer. From my experience, they would weigh against the criticality of the chemical or fluid in used, and pressure of the system.

Some power plants have water treatment facility and chemical processes plant to support it The one I've work before uses B31.1 for the main plant. But B31.3 for the chemical plant.
