Was there a reason in div2 class vessel removed the 1.43 multiplying factor from the hydrotest and only uses 1.25 for 2019? I could not find the reason they changed this. I dont have 2017 in front of me, but im pretty sure 1.43 was an option in the table 4.1.3.
thanks

I believe Im going to make a block with a milled slot (shaped like a U) with a hole in it for the bolt threads clearance. The nut is on the bottom side. A removable pin should keep it from wiggling its way out, but can be removed to replace the nut when required. We can always hope there is...
I want to fix several high strength nuts to a structure so they do not get lost when in the field and will not require a second wrench to hold (when removing/installing the bolt)the nut since the nut is in an awkward location. It is an application where a unit is bolted down for hauling, then...
I was trying to find out what the pressure rating is at 250F. It is currently in a 120F (10m rated for 10,000psi) design, but we were wanting to increase the temp to 250F. It sounds like we may be in good shape then. I will see what I can find in API TR 6AF1 to verify and document.
Thanks for...
I am trying to determine the pressure ratings for a given temp(chart or curve) for API 6A flanges. I have found a unofficial chart, but cannot seem to find anything trustworthy. Hopefully this is posted in the correct category.

We are moving into the world of div2. I am currently using Compress to design our Div 1 vessels. I have a PE that will check our design as required on the Div2 vessel. I am wanting to do as much of the design as possible while I am simultaneously learning Div2. We have the Compress Div 2...
We have a 60" x 120" that we are going to have local PWHT. I have never tried this method, but find a HT company that specializes in this, and they can take care of you. I believe they use heat blankets. What is the wall thickness thickness of the vessel?

Does anyone use routing to do complex welded piping? The routing library consists of only flanges and pipe. I am curious if there are users that have built up libraries of parts and believes that routing is a good tool. Cadworx is great and has a full library, but it is not compatible with...
Are you referring to the tap drill size? A tap size chart is fairly simple to find. Machinerys Handbook has a section on npt threads and minor dia of threads for a given depth. Good luck.

sNtmAN,
I'm surprised there isn't a corner radius requirement. Thank you Sir for your response.

I have a weld neck flange that will need to butt weld to a nozzle that is thicker. I am simply trying to determine the required and simplest method of making the transition. UW-9(2) and Figure UW-9-2 states that "The cl of the butt weld attaching a component(flange)to a thickened neck nozzle...
They are from the routing piping library. Im not sure what im trying to do will work. I can insert it it, then flip the flange around and change the mates, but it still is not what I want. Again, all of the tutorials show finished tanks with all of the flanges and welded fittings already on...
Im new to routing for asme vessel flanges and pipe runs. Ive got the hang of it when the tanks already have the flanges welded on the tanks. My question is this.....when designing new tanks, what is the best way to add the flanges, olets and other fittings to the tank? They will be welded of...
I went on a job interview yesterday and they also wanted me to do a quick solidworks test. No biggie. Ive worked with SW for 9 years up to version 2015. Well, the colors were totally different and some of the icons changed. Nothing too dramatic, but just enough to be an irritation. I was...
"If you try AutoCAD 3D now, with your SW background, you will need a rubber room after about 1/2 hour"
This is so true. Drawing a 3d model in acad is painful. I stopped using acad 2d around 2006. I downloaded the 30 day trial of 2016. It started coming back to me fairly quick. Im old school and...
I used acad for years, then switched to solidworks for the last 10 years. Long story short, I am looking into changing industries due to the oil and gas industry being crippled. I see many jobs for autocad 3d requirements. Well, I thought maybe autocad had really changed and must be practical...
I was laid off after doing downhole wireline logging tool design for 18 years. THe dfw area only had a handful of places that did this type of work, but Baker Hughes and Weatherford both shut down their facilities and moved to Houston. THe company I worked for may or may not survive. Who knows...
