Just for information , the pipeline will be underground.

And ifit is considered as pipeline (since it can cross a non company proporety) , can i say that when the material undergo tests according to KD10 of ASME DIV3 , then we can consider working with higher pressure ( more than 3000psi) Note (a) Table GR-2.1.1-2 (PL) Thank you again for your advices

Ok thank you again but what about the note that states that when the material undergo tests according to KD10 of ASME DIV3 , then we can consider working with higher pressure ( more than 3000psi) Note (a) Table GR-2.1.1-2

The pipeline is 4inch & 300m of lengh.( it is a flowline NOT really a pipeline...)

@1503-44 : Thank you for your response. However, concerning the note under the table GR-2.1.1-2, it appears that it does allow us to use the specified materials at pressures exceeding 3000 psi if they have undergone testing according to KD10. Your guidance on this matter would be greatly...

Hello, I'm currently involved in a hydrogen pipeline project where the design pressure is 350 barg. According to ASME B31.12, this pressure level is excluded for pipeline design. However, in Table GR-2.1.1-2, there's a note that states: "The maximum operating pressure (MOP) shall not exceed 21...

thank you for your advice please check if it is deleted ^^"

I am currently preparing a piping class. For the calculation of wall thickness, I will utilize the formulas provided by ASME B31.3. As for the determination of allowable stress and joint efficiency, I will select the more stringent requirements between PED and ASME B31.3. Please let me know if...

What is the formula for calculating the thickness in compliance with both ASME B31.3 and the European Pressure Equipment Directive (PED)? While ASME B31.3 has more conservative allowable stresses for carbon steel materials compared to PED, the guidelines for austenitic materials are not as clear.
