Dear Zafar,  Here my recommendations: Define the schedule of the pipe, define the length of the span for the flushing, and define the test time. Secure the pipe anchors and supports. Check that it does not generate induced vibration towards static equipment nozzles, as it can generate cracking of the weld. And most of all, be cautious.

As an additional note, I am referring to submerged arc welding for horizontal seams and wonder if there is a limit on the shell plate thickness which requires 2-side welding.  Patrick On Wed, 20 Oct 2021 at 11:25, Ying Piu Ng < ngyingpiu@gmail.com > wrote: Dear Experts, I am working on the construction of aboveground circular steel water storage tank.

Hi,  There's one option in B31.3,- U341.4.1. A weld coupon examination in accordance with para. U344.8 May be used in lieu of 5% random radiography/ultrasonic examination required in para. 341.4.1(b)(1) when the following  are employed in fabrication. 1. Autogenous automatic welding  2. Automatic orbital welding with the use of consumable insert rings. There is no option for hydrostatic in lieu of RT.
