Hello, I would recommend to post your thread in the HVAC/R engineering group if haven't done yet. Good luck.

RVAmeche, Thanks for the reply. I am on the Vendor side and not EPC. That's an easy fix to my problem. My question is mostly on the technical side and need an opinion on my understanding of bolting requirements as per B31.1. Is this Client asking for something beyond code requirements or is he...

Hello and Good Day, I am working on a power plant project (ASME B31.1), and the client is asking to use High Strength Stainless Steel Boltings (SA-453) for all raised face welding neck Stainless Steel flanges and spiral wound gaskets. My problem: Table 112 of ASME B31.1, as per my...

Thanks to All for sharing their comments.

Dear pennpiper, the socket is 20 mm diameter with 10 mm depth and then it reduces to 13 mm, in order for a 0.5" pipe to be inserted. The drip ring has come as 1.5" width and 5.75" diameter. It can't be welded to a SOL as space is not enough. Thanks.

Hello Folks, We bought a few drip rings, 3", 600#, with 1/2" tap. They all came in 1.5" thickness. They all also have a socket shape inside them, please see attached sketch. Our Client is insisting to weld a Sockolet on the tap (3" x 1/2") and proceed with welding the nipple and valve. The...

Hello Folks and thanks for all the feed backs. My apology as I was not clear about the application which is Hydro Testing of piping systems.

Hello and Good Day Folks, Our contractor has asked us using windshield washer fluid as the test media as we are entering the cold season instead of water-glycol solution mixture. I understand that the windshield washer fluid contains Methanol. Has anyone had experience doing this? Is there...

Sorry XL83NL, it won't happen again.

Each weld creates a Heat Affected Zone or HAZ, the ideal case is not to have the two HAZ intefered. Determining the HAZ is not an easy task. I think (but not sure) that you should have at least 2 inch or 50 mm space between the two welds. Take care.

Hello Folks, I am running C2 2013 R1 and got stars instead of digits in my displacement report. Any idea of the reason. Thanks in advance for help.

Hello LittleInch, I elevated the concern to higher management and they are all agreed with your comments. After showing these numbers to the Client, we are going to change the design to a system with proper vent and drain. Thanks a lot, Frank

Thanks a lot for your feedbacka. V=50 m/s Slug Density= 984 Kg/m^3 Slug Length= 118 meter

This plant is existing and there is no proper drain/ vent system. We already asked the Client to modify their system but no success. The velocity and density are coming from Process engineering. The one parameter that process has a problem to provide us is the slug length. We used F=p.A.V^2...

Hi Aladin5020, Would you be able to provide more info on this anti-water hammer like vendor website,brand etc.... Can we use them in Industrial applications? Thanks in advance, Frank
