Thanks for all answers.
bimr,
This is the reason, NFP 24 show forces only for PVC and ductile iron, since its connections are bell or spigot?

Hi msquared48
The system, I need to evaluate is a 16" diam, GRE pipe.
To join the pipe, we use a socket union, like socketweld, but with special resine, it is also necessary for aboveground systems, the thrust blocks?
Thanks for the help.
B. regards
Luis
Hello friends:
According NFPA 24, each change direction in a pipe route needs an anchor block, for thrust pressure.
It is necessary for each change direction, aboveground and underground?
According construction department of the Company, they never see this anchor blocks, in any firefighting...
Hi everyone
I need to evaluate a piping system, there is pipe way, for almost 8-10 lines. 2 pipe DIAM 18" A333 GR 3 and 6 pipe DIAM 8" A106 GR B. the pipes go from ground coast to pier. Between sleepers (two piles each one) and pier, there is a transversal movement 1 1/4" innches. Also...
Dear Folks:
I am going to begin the design of steel plant, so I need to define the codes for apply.
Do you know what piping codes can I apply for design?
ASME B31.1 Power Plant, motion fluid, generally for electric generation, like steam.
ASME B31.3 Process Piping. Is there some place of...
Now I understand your question, so it is neccessary to calculate the stress for a specific condition, like span between footholds, allowable stress can be assumed like 2750 psi as Kellogg, and then calculate the deflection nad then angle of deflection. In an excel you can make fast and easy...
Thanks every body
I am going to use A333 Gr 9 or Gr 9 for CO2 -60F. Now I have one more question about welding, hardness test, heat treatment after welding.
Somebody can help or some guidelines about it.
B regards.

Hi npao:
Deflection as I know is a dimension, not angle, you can calculate the deflection angle when you know deflection and the span of pipe. Now, the angle = arctan (deflection)/(span/2). For max defelction you have some criterias, for power piping B31.1 0.1 inches & for process piping as...
Dear syedfarhanali
Thanks for your help. Now I have a better idea about selection of material, now I have another question, how about other super alloys, like Inconel or Monel? This page doesn´t have info about them.

Hi:
I want to select material piping for CO2 service -60°F@100 psig, liquid. Searchig some information, I found in "Pressure Vessel Handbook" from Megyesy a table, with Chemical Resistance of Metals. With a recomendation that CS is "fair" for use in CO2 (dry) & "Caution" with CO2 (wet). This...
Hi:
I have some troubles defining mainline block valves, ASME B31.4 refers to "major river", but how to define it, how depth?, width? flow rate?. The pipeline has 27 km, and cross at least 4 rivers and 15 marshes and swamps.
How many mainline block valves I have to put on it?
Best Regards...

Here in South america, there are few people who makes pipe stress analysis, ans in Ecuador less, actually I do some analysis, but I studied some books for mysef, and reading papers and help of Caesar II, I also take the basic course of Caesar II with a modelosoft instructor.
If you can guide me...
Hi:
Anyone knows where is the official forum of Caesar II. I try to enter it for severl times but, it appears offline.
Someone knows when is it back online?

Hi:
I need help, about how to input data for a pipe stress analysis in a buried pipe, 12", with casing and inside of another pipe (16"). This is for a pipeline, crossing a river about 45 ft & underground like a 9ft under a bottom of river.
I have all the info of ground for the module of...
