I am looking for standard torque values for U-bolts, used to support pipe, ranging from 1" to 6" pipe. Does anyone have a nice torque table or chart that I could use as reference for this application?
I've been told that you can't get a CSA rated globe valve. I need a 1" CL150 flanged globe valve for low temp service (-45 deg C), medium = natural (sweet) gas.
Has anyone heard of any globes valves like this that are CSA rated? Our preferred vendors are saying no but I thought I would reach...
I have a 3" pipe spool with a carbon steel WN RF CL150 flange (ASTM A105) and it needs to be bolted to a mating CL150 flange made of stainless steel (ASTM A182).
Are there any practices that I should be aware of, to prevent galvanic corrosion, when bolting the two dissimilar flanges together...
This might be a silly question...
I am aware of normal temp (min temp. = -29 deg C) vs. low temp (min temp. = -45 deg C) CARBON steel pipe and fittings, but is there a similar relationship between different types of stainless steels?
From what I see in table A-1 in B31.3, most stainless steels...
I am looking for an NPS 1-1/4" x NPS 1/2" threaded reducing tee avaible in Class 3000? I know that they are available in class 125, 150, 300, etc. (as per Anvil International catalogue), but I haven't found one in Class 3000. Do they exist?
I also ask because they are not listed within the ASME...
Does anyone know the distance you need to be away from a road or railroad right of way when hydrostatic testing untested pipe in the field?
Clause 8.7.1.4 of CSA Z662 states that the road or railway needs to be closed during pressure testing for pipe installed at a road/railway crossing. But at...
Does anyone know the minimum separation distance between the edge of a pipe bend and a hot tap saddle? And also the same for between a circumferential weld and a hot tap saddle?

Why do we have to specify both the pressure class and the material grade of a butt-welded flange (in particular, a WNRF flange)? It seems redundant to me to call out the pressure class (ex. PN 100) if I'm already specifying the material grade of a flange as well as the matching grade & wall...
