What is the design pressure of the pipeline?- 65 barg
What is your role? The inspection company should be able to address your questions surely.-
We have already requested the inspection company for feedback. I thought of finding an answer meanwhile.
Is it in a very corroded state?- its a new...
Thank you LittleInch for the feedback. I had this same doubt whether the pipeline such long behaves like a pressure vessel. But the query came from client. And yes, I am learning and do not have wide experience with pipelines.
We are planning to do pipeline inline inspection pigging using pneumatic pressure of 20 Bar. Pipeline length is 20",16km, with a total volume of 3060m3. I performed Stored energy and safe distance calculation as per ASME PCC-2 part 5 article 5.1. The value is very high with a safe distance of...
"Mitered bends are prohibited". This is a statement seen in some of the client specifications related to High Pressure Gas Pipelines. What would be the reason's for this.
Please advice.
Thank you @littleInch. We have already done the cold bending with 1.5m tangent length. Because of alignment issues at one location at site we have to cut down the straight length. Best way as you said would be to get the deviation discussed and approved with client. But prior to that, i wanted...
Thank you everyone for the responses. To add, our client has specified that the start or end of the bend shall not be any closer than 1.5 m from the pipe end or within 1 m of a girth weld. Means there should be minimum 1m from the bend portion to the weld.
Is there any specific code reference...
For an 8” 2500# pipeline (API 5L X60), we have made cold bends of 40D. For bending we have considered min 1.5m straight length at the start and end of bends during bending.
However due to site alignment requirement, we will have to cut the 1.5m straight length and weld the cold bends directly at...
