Hi,
Can someone tell me when it's recommended the use of RTJ flange?
I have seen in many projects that for high pressures (i.e. over 600# or 900#) it is always used RTJ in process gas applications. Now I'm facing one in which RF is applied until 1500#, which is surprising for me.
I have read...
Hi all,
I am recieving from the engineering company some data confusing to me. For a carbon steel pipe with approx. 100°C op. temp. and 300#, in some cases we have to do 100% radiography to the welds and in other cases only 33%, in prefabrication.
I have check the code (344.5 of B31.3, which...
Hi all,
When thickness of a pipe is calculated, it is used the design pressure.
On the other hand, the test pressure is 1.5 times the design pressure (forget about temperature corrections).
1. What would happen if the commercial thickness chosen was so close to the theoretical design pressure...
Hi all,
I'm wondering if the B31.3 code can be used for vacuum pipes. In the exclusions of the scope (para 300.1.3) it is said:
"
This Code excludes the following:
(a) piping systems designed for internal gage pressures at or above zero but less than 105 kPa (15 psi), provided the fluid...
