Help - thickness of pipe

[braham0793]

Mistakenly buy 9 tubes of six meters in sch 40 de 2" in ASTM A106, when I had to be in sch 80 - astm a106, on this stretch of pipeline will flow water and is designed to operate at 10.3 barg. Meetings are threaded.
I wonder if I can work with these tubes or I have to be refused, considering in turn possess 10 tubes in sch 80 of the same law.

In all I need 19 tubes 80 sch.

Quisiera saber si puedo trabajar con estos tubos o los tengo que desechar,considerar a su vez poseo 10 tubos en sch 80 de la misma norma.

En total necesito 19 tubos en sch 80. "

Seems like a very thick wall for only 10.5 Barg. What's up with that?

 

[braham0793]

The process that is performing this piece of pipe is reverse osmosis, I think I can work with thicknesses of tube 2, are saying?

 

[BigInch]

I didn't run the calcs, but if pressure is the only concern, there is a lot of extra wall thickness for that pressure. Be careful as the designer may have believed that high mechanical forces would require thicker wall than that need for pressure alone.

 

[braham0793]

Good temperature is designed to operate at 65 °C.

 

[BigInch]

That temperature would not reduce the pipe's allowable pressure very much at all.

Maybe it is OK.

Please tell us:
Design Code
Design pressure
Allowance for threading
Any other allowance (corrosion, manufacturing)
Any other forces?
Is it buried or above ground?
What are support distances?


Why was Sch 80 chosen?

Sch 40 is a bit low for 2" to resist mechanical dmage ( people)


Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Becouse of the threaded join must be sch 80 considerin thickness reduction a thread.

If treading is the problem, weld all the joints.
