Look at adding gussets perpendicular to the lug for reducing the stress on the "lug". If the hole size of the clevis pin is of concern add a pad plate to lug. Use a clevis through the clevis of the lug to reduce the moment on the weak axis of the lug. Can you describe how you calcualted the...
Hi TGS4,
Thanks for your information and clarification.
I understand the ASME Code and your point. I was not trying to answer the ASME Sec VIII code but rather what would work if your outside of the code rules already?
Why was the clip under designed per ASME Code Sec VIII in first place...
Here are a few suggestions:
1) Check your material certificates for your 304 plate and see what the actual tensile strength is. You can use this as your value.
2) Check the strain at your calculated stress and see if its less then 2%. If it is your probably ok.
3) What stress is high, primary...
Ok I will check out the California Building Code and make sure the current amendments are included. I will also call the building department for their requirements. Thanks!
If I am going to put a 2 inch hole in a the wall of a CMU block building built to 1965 code do I have to redesign or modify the entire building to current day standards because it was modified? I understand the local building departments involvement and I greatly appreciate your response cvg. I...
I want to know what Code requires design retrofit for buildings in the state of California. I am modifying a small building that was built in 1965 and I want to know if the entire building needs to be upgraded and what code allows/exempts required changes.
I am curious in understanding what makes 302 Stainless Steel bleach compatible. I have made experiments with small springs made from 302 SS that have not corroded.
Is the 302 steel resistant to oxidation from hypochlorite (OCl-) or is it resistant to the hydroxide (OH-)? How is 302 steel...
Compositepro, sorry, I meant to say higher temperature to lower temperature. I just wrote it wrong. Thanks for correcting me.
To all, even though the temperature is rising for the cooler material and is still less then T high. I am sure there is a conduction within the object at T low absorbing...
Great information and insight but are you talking about temperatures below the heat supply temperature and probably not perfectly insulated from other cooling/heating source like radiation or convection, if possible? I still think the heated object temperature (object at lower temperature) can...
I am in agreement with your statements about older installations and vent calculations are documented that way in NFPA 68 2007 also.
Good chat and I appreciate the help.
About the calculation, if the methods for determineing required vent area have changed from the new NFPA 68 2007 edition is it realistic to say that the old calculation is no longer valid?
Would it be fair to compare the new calcualted vent area vs an existing vent area that may have been...
I agree that Silos indoors need to be vented per NFPA 68 2007 but do the Silos outdoors away from personnel need to be vented as well?
NFPA says, all combustible dust enclosures should be located outdoors. If they are indoors they should have vent protection as per the standard. It "NFPA" does...
Hi Expert Help,
So, a material when heated (properties willing) can reach the same temperature of the heat source and can never exceed the temperature of the higher temperature heat source?
This assumes the higher temperature source has an infinite supply of energy to remain constant.
( I...
