Steve,
I can't find anything in the code (B31.3) regarding the dimension I am looking for. Most of the reference that I've found on this matter pertain to the thickness (height) of the pad. The SIF calculation in Caesar is the same. Only the thickness is entered.
The one reference in B31.3...
I am trying to determine the required length of a repad that I have requested to be added to a stub-in tee (12" run and branch dia). I concluded that I needed some reinforcement on tee during the pipe stress analysis.
There is not enough room to fit a better quality fitting (welding tee)...
Does any body have any experience with the use of mono-flange valves in use for crude oil systems? I am looking at using a mono flange double block and bleed valve but I am worried that the crude may have a tendency to plug up the small ports/passageways integral to these mono flange valves...
I need to know the physical dimensions of an 18" x 16" B16.9 concentric reducer. That is, what is the length of the 18" portion up to the transition and, conversely from the other end, how long is the 16" portion up to the transition section. Any body know where I can find this information...
We need suction cups to be used during the installation of the window pane to fit in place. We need to use a scaffold to lower the window in place and then fit in place to allow for installation as per maufacturers instructions. The recommendation of the use of some sort of suction cups came...
I have a job at my facility where we are planning on installing a new window at high elevation. The recommended installation plan called for the use of 'suction cups' to install the window pane in place. The window pane itself is 650 lbs. I am in the process of checking with Vendor...
well that is the approach that I am hoping to take... if it ain't broke don't fix it...
I have been in consultation with a valve vendor for a particular type of valve that reduces emulsion of produced water in our crude on the separation train of our facility. The vendor's recommendation was...
what difference does concentric versus eccentric reducers have on the flow profile through each? I have been told that eccentric reducers create a higher turbulent flow. I can understand why this is so because of the geometry but I haven't been able to find any documentation supporting this...
Can anybody tell me the difference between a Class A and a Class B type of spacer. I need to order a 26", 150# spade for one of my jobs. Apparently I need to specifiy either A or B. Can any one shed some light onto this or show me where I may find the information I need.
