I have horizontal launcher-receiver designed to B31.8, saddle mounted and bolted on skid. Not sure what calculation shall be provided by the trap manufaturer for the saddle. Can not find any reference to saddle calculation in B31.8. Is Zick Analysis (for pressure vessel) acceptable even though...

TD2K, It's a separator, DIV-2 design with DP 1350 psi @ DT 170 F

I have a situation where instrument nozzle on vessel is CS 600#. But specification dictates that level guage flanges should be 316 SS. I can not use 600# SS flange because of lower strength of SS. Is there any duel certified material (or other solution) that I can use instead of upgrading to...

Thank You Metengr. My application is pig launcher for gas line. Launcher material API 5L Gr 65. DP 1467 psi @ DT 150F. I want to check ASTM A694-F65 600# flange rating at 150 F. But can not find it anywhere. What is the procedure?

NozzleTwister, Thanks again. All I need to know is the psi @ 150F for 600# class for ASTM 694 F65. Is it listed in MSS-44 ?

NozzleTwister, Thank you. But I think MSS-44 is for large flanges. Does it apply to small bore flanges (2" to 8") as well?

How do I find out to which material group (or Pressure Temperature rating table) of ASME B16.5 does ASTM A694 F65 belong? I can not find it in B16.5. A reply will be appreciated.

Could someone please tell me the main technical difference between ASME 31.3 & API 14E from piping fabrication & installation point of view. The reason for asking: I have a piping fabrication & installation specification written as per 31.3. Can I use it even if client's intention is API 14E...

Could someone please tell me the main technical difference between ASME 31.3 & API 14E from piping fabrication & installation point of view. The reason for asking: I have a piping fabrication & installation specification written as per 31.3. Can I use it for 14E piping code? Many thanks in...

I have a PID which shows Pig Launcher & Receiver shall be as per B31.8. So, when I write the spec for Launcher & Receiver to which code I shall refer to for fabrication details, 31.8 or ASME BPV, specially for (1) Welding Procedure & Welders Qualification [31.8 or BPV Sec IX ] (2) Heat Treatment...

Thank you gents for your recommendations. Much appreciated.

I want to buy a book on PV (Designer's Handbook type with worked out examples) explaining necessary sections of ASME VIII div 1 in a nut shell. A recommendation (book's name & author) from user's point of view will be appreciated.

Lilliput1: Thank You. I have used your formula for estimation. DrWeig: It's for a new installation. Thank you.

Could someone please help me with the following calculation: How do I calculate the heat generated by the following electrical equipment: a) 2 x UPS units each running at an electrical load of 4kW b) 2 x UPS units each running at an electrical load of 4kW c) 2 x UPS units each running at an...

Why select 316 or 304 for gas vent pipework

Gents, Thank you all.

Metengr, Thank you. So, back cladding and roll bonding are the same thing or different ??

Could some one please explain me (in few lines) or refer to a http link, weld overlay and back cladding procedures (with advan. & disadvan.) for PV application. Many thanks in advance.

Can someone please give me the section number in ASME Code where I can find the allowable nozzle load for a PV.
