Hi I would like to know is there any part in the Div 1 code that specifies when single bevel butt weld can be used to weld head to shell? I mean by single bevel butt weld: that a pipe will be butt-welded to a SE head. The head has bevel 37.5 but the pipe is plain end has no bevel. Both the head...

We used B7 zinc plated and they rust

Can S/S B8 studs and S/S SA194 Nuts be used on Carbon steel A105 Flanges ? I have an application that the external environment is corrosive and from experience the Studs and nuts are always corroded after few months. However the flanges don't corrode because they are painted with special...

Think about: - Galvanized pipes which are not that expensive - Plastic pipes suitable for your fluid - Carbon steel with thick wall to be good for x years

It's not a good practice to install piping directly on rod bars, however you may weld a plate to your rod bars and install your piping on it. Ensure that your piping will not fall down from the rod bar... so you can drill 2 holes in the plates to install a U-bolt. Finally, ensure that your rod...

For such case, I would model it in Caesar. However if you need a rule of thumb use table 121.5 in the B31.1

I believe friction force (axial) is important in the design of supports. If you have a steel on steel (friction coeff = 0.8), the friction force = 0.8 x Fy Fy = weight + vertical load due to thermal With a 10" pipe filled of water insulated and cladded, you can have easily friction force >2000...

So the system curve will still the same but the operating point will change as the flow rate will increase .. Is that right ?

The question in other words... Does the operating point of a pump will be affected if new parallel lines are added ? These new lines have lower pressure drop than the existing ones. 00000 -------------------------- existing line Pump -------------------------- existing line 000000...

Hi... A simple question but I cannot remember it I have closed loop consisting of : - a circulating pump. - 5 loads in parallel I know the system resistance curve and the pump curve .. and I know the operating point... My question is I will add another load in parallel with small pipe run and...

B31.3

According to ASME B31.1 you have to use seamless carbon steel pipe

Hello Is it possible to have ASME rated elbows with non standard angles like 25 Deg - 55 Deg - 75 Deg ... for 10 " diameter ?

Thanks JohnBreen for your post, If the thickness is not standard, so what's the difference between reducer schedule 40 and reducer schedule 80 ? What type of test should be done ? hydraulic test ? Can I order a reducer with a custom thickness ?

Hello I need to buy a Carbon steel concentric reducer 10/12" flanged. My pipes are XS. I need to have the same inner diameter. What type of reducer should I buy XS or SCH 80 ? Does anyone have the dimension table of reducers XS & SCH 80 which shows the inner diameter ? Thanks
