But, in the long run, it may be cheaper and simpler to use Class 600 flanges.
Suggestion: Can the 57 barg design pressure be better defined ?
Is this a "peak pressure" that the system will only see ~1% of the time ?
Is there a...
Thank you saplanti
Is Pall= Allowable pressure? I have seen that it fails but I think if a more percise calculation will be done the flange has no problem. That is why I want to use cases 1 to 6 and I think case 3 and case 6 produce the bigest allowable stresses on the flange.
Even in your...
Hi and thanks for your time
a)They are part of a piping sytem
b) Yes ASME B16.5, Class 400
c) I think ASTM A105 but must get back to you for that
d) No external forces. I am even thinking of requesting for a new pipe srtess analysis with new pipe supports with all external forces mimimum as...
I am in a situation investigating if #400 flanges are adequate for 272 Celsius and 57barg. We have the design drawing of the flange. So I am thinking of asking a calculation of it's strength from an engineering consultant company. I am not sure what exactly to ask for. From what I have found on...
Hi guys
Many times I am asked to Buy a valve so I have to evaluate the bidders. What documentation shall I ask from them?
I usually ask CE0036, ISO9001, EN10204 3.1 for the raw materials, valve curves, calculations for operation point, certificate for tests and inspections, period of warranty...
Nope it must be FM approved.. FM obliges us to use indicators
Anyway I will call a supplier tomorrow. Thank you for time
Is it right to refer to the housing of the indicators as Post Indicator or Indicator Post? I have seen it both ways
When installing telescopic extension spindles the cap should be over the ground level? I can't see any other way to mount a Post Indicator on them only if their length is enough so the cap is over ground level .If the length isn't enough and ta cap of the telescopic extension spindle is...
Thank you for your response
The installation guide dosn't show how to fasten the length of the telescopic mechanism. Does it fasten??
If not how can we secure a joint with the stem of a Post Indicator ?
We have installed AVK Telescopic Extension Spindles for buried water valves. How does the length of the extension spindle lock at a desired point??I can't find any installation guide.
