Thanks for the excellent link! I've never heard of that website. I can't ask the client rep - I am the client. Tradesman is a Canadian term for a journeyman who belongs to an indentured trade such as welding or pipefitting.

Try Victaulic Style 90 or 99 Plain end Couplings. I have used these to join ductile iron to carbon steel pipe on a gen-set cooling circuit running ethylene glycol at 200F.

Is anyone aware of a prohibition on the minimum spacing between two adjacent butt-welds in B31.1 Boiler External Piping? Do any of the ASME Codes restrict this spacing? My tradesmen tell me that 1-1/2 diameters is a rule of thumb, but that seems pretty excessive.

Thanks swearingen - I found a used book dealer that has the whole three volume set so I ordered it. I already have the 1983 AISC "detailing for steel construction", but it doesn't have much "detail"!

Here is the link to my image. http://www.imagehoop.com/view_image/8f54f1412/cope figure.bmp

Very Funny. Does the image appear to you? I just see a box with a red X in it. When you right-click the box and select "properties" it shows you the link.

Can anyone identify the manual from which I found this one page?

We have several large condensate storage tanks here at our combined-cycle power plant. They are all steel construction, lined internally with an epoxy coating. Carboline has several good products. Your condensate looks pretty innocuous. Stainless is overkill, and fantastically expensive to...

I once (10 yr ago) used the Richardson manuals for cost estimating process piping installation costs. I did a google search today and can't find any hits for Richardson Engineering Services. Anyone know what happened to them? Is there an alternative manual (other than Means) that people would...

I have searched the entire eng-tips site, and can't find any posts on this. I am reviewing a diesel fuel additive pitch (very skeptically) for a product that supposedly can reduce NOx and PM as well as increase efficiency. It dices, it slices, it makes Julian fries. The dosage rate is very...

I use a Hilti laser rangefinder. It's a little hard to use in bright sunlight but is quite accurate.

Try the "Machinery's Handbook" which should be in Section 621.8 of any decent library.

I would think that deducting the depth of the threads from the nominal wall thickness (minus the 12.5% tolerance) would give you a conservative burst pressure. Since the threads are tapered, the deepest threads are actually at the very ends of the pipe where they are restrained in the radial...

Don't bother with ABSA - their jurisdiction is pressure vessels, not atmospheric storage tanks. For what it's worth, one US Arctic mine I have worked with uses SA516-70 normalized plate for outdoor oil storage tanks. An Arctic Canadian mine specified: "Material shall be in accordance with CSA...

We operate in Canadian winters with steam lines, some 600# and some 100#. Slope steam mains to drain boots which are trapped to the condensate line. We use mineral wool on low pressure, cal sil on high pressure. The condensate lines should be insulated and steam traced with stainless tubing...
