I need to measure the negative strain after autofrettage (60,000 psi) of a thick walled vessel.
In the past, I have used special sealing glands to connect the strain gauges to the outside where I could record my data. However, these were expensive and prone to problems.
Would it be viable to...
Question:
I am doing a demonstration vessel with 8" sch 80 pipe (1/2" wall), a 8" pipe cap and flange at opposite ends. I intend on putting a thread-o-let on the side of the vessel.
I have all my materials on hand and now I see in my design calc's that UW-16 (3)(a)(1) is limiting me to 3/8"...
Background:
I am designing an ASME Div.1, -20 to 100, MAWP 150 psi, water filter. It is constructed of 42" dia pipe (~26 long), with a welded head on the bottom, 10" inlets and 10" outlet come thru the bottom, the top head is constructed of a head welded into a ring and is made for easy...
Concerning the rules in Sect. VIII, Div. 2: for torispherical heads.
Step 2 page 4-50
0.7 <=L/D<=1.0 (eq. 4.3.5) or go to Part 5.
I am designing a vessel out of 8 inch pipe with torispherical heads.
The D=7.625 in and the L=8.625.
Because the inside crown radius equals the outside diameter...
I am guessing this is the proper forum for this question, but I am unsure.
In the state of Texas, the PE’s firm must be registered with the State as providing engineering services if the PE is practicing engineering.
I am a partner in a manufacturing company. We are going through the process...
I am trying to use my library features, which are API 6A flanges. They will typically insert with no problems as long as I do not deviate from the orientation from which they are created. However, if I want to use a flange on each end of a part, then one side will work and the other side will...
I need a jump start on old fluid equations.
I have a piping manifold as follows:
14 inch header pipe with two 35 foot parallel branches (8 inch pipe) coming off one side. On each 35 foot pipe I have discharge flanges (4" 150#) set in pairs at 5 locations (10 discharge locations on each run of...
Several years back API listed a NPT thread called long line pipe - basically the start of taper is smaller and the diameter at the hand tight plane is the same. The L1 dimension is longer than a standard NPT.
Does anyone have the old copy of API - I'm guessing it was published in the 1970's...
Question:
Some years back (guessing about 1970) API 5B had a variant of Line Pipe threads - called long line pipe.
The primary thing different is the L1 dimension which is longer and basically extends the length of the thread. The E1 is still the same.
Can anyone tell me what the increase...
Question:
Can you induction harden stainless steel - such as a 410 or 440 grade?
Is there any other reasonably low cost material where a good corrosion resistance and hardenability to RC40 to 50?
