Hi - have short spools 6 & 8" to be casted from A494 CW6MC with both ends formed into 600# rated flanges. This material is not listed in B31.3, II D, B16.5, B16.34
From ASTM A494 i can get the tensile & yield values but struggling to elevated temperature allowables & P/T ratings.
What options do...
We have a pressurized calibration loop where we want to reduce cost for spool sections. We want to be in compliance with B31.3 generally.
As we need to have inner diameter to a certain dimensions (8" sch 40), we can get 2 or 3mm plate rolled to this ID.
To be in compliance with B31.3, do we...
Hi all. My company builds flowmeters using short pipe lengths (A106, A312 etc). Is there a standard that states the heat number must be transferred between the new pipe from the original pipe section.
Of course common sense should prevail but I’d like to know if there is an international...
Hi – last year a purchased a panel heater but since it has stopped working, I have established that it is the thermal fuse that is gone.
I cannot find on the internet the same fuse, so I need some help to understand these components. Since I cannot find the exact same fuse, I need to figure how...
Hi I’m relatively new to Norsok requirements on oil & gas equipment. My understanding is that material to be used shall come from a Norsok Qualified mill according to M-650. This mill would need to have a QTR certificate for each type of material.
I’m being told that if I get the steel from a...
Scenario: Design Code B31.3. Branch connection to pipe run is hill side.
Code Clause: 304.3.1 (b) (4) “the axis pf the branch intersects the axis of the run”
Problem: B31.3 does not consider hill side branch connections.
Solution: Refer to 304.7.2, but this does not allow calculation to ASME...
Due to space restrictions I wish to design a linear actuator using trapezoidal screw, see attached sketch.
Travel required=730mm
Required time=25sec
Motor Speed=584rpm
Mass=45Kg
l=Screw pitch=3mm
dm=Mean pitch diameter=12.45mm
f=Friction coefficient=0.15
F=Load=441.45N
Calculated torque...
Trying to design a piping system with duplex pipe material S31803 A928 CL1 to ASME B31.3.
B31.3 does not list the stress values for this material.
Is the correct procedure to use a similar material in B31.3, say A790 S31803 or should one refer to ASME II Part D?
Per the example above if one...
Hi,
Our company provides equipment with armooured coaxial cables (RG62 A/U). We have a requirement to supply our equipment into a hazardous area, that is not ATEX but FM/CSA certified.
We can procure CSA certified armoured cable glands, but im not sure if its possible for procure FM/CSA cable...
We have a new vesssel to design. The vessel Contents are deemed to be "highly carcinogenic, which have the ability to penetrate the skn causing serious harm".
Does my vessel fall under UW-2?
Tks

Hello,
Were having a problem in getting a vessel to pass full vacuum. The vessel shell is out of 3mm and we can only fit one stiffening ring due to nozzle placement..
We cannot get the moment of inertia sufficiently with one ring. Is there another way around this?

Hi there.
I've turned my 3 GB switch on, and re-booted using the 3 GB option. When i start INV 2011 > Help > About. It shows that im still only on 2GB. How do i force INV to use 3 GB??
Hello
I'm looking to buy two forged body flanges approx dimensions

Hello,
I'm designing a conventional jacket to ASME VIII, Div 1 and want to calculate the jacket closing ring thinkness. I've looked at App 9-5 and i think this is the correct section to be looking.
I have checked a heat transfer book and this refers to Para UA-104 (ASME Code).
I cannot find...
Hello!
I've to design a vessel that has a body flanged top head (see attachment). There are to be 8 swing bolts that will fix the head to the rest of the vessel for operation. Design conditions are 4/-1 Barg, 180/0 Deg C, 1370mm ID.
I really dont know where to begin with this design. We have...
Hi
I’m designing a silo for storing oil. Shell height is 11500mm, 3800mm internal diameter, internal pressure 490mBarg.
15 Degree Conical tops and bottoms. Supported on a mild steel skirt.
I’ve searched most of the codes but finding it really difficult to find the correct calculation for...
Hi
I'm Trying to create a 3D fillet on a part for a vessel that im designing.
Normally we just draw this detail in 2D cad but now we are changing to Inventor.
From the CAD dwg you can see what I need to create but I cannot for the life of me figure out how to do this in 3D. I have created...
Hi
I’m trying to complete PED classification for a pressure vessel with limpet coil. I cant decide what way I should analysis the jacket, i.e is it a vessel or a pipe?
Any ideas?
Thanks
