Issues regarding the welding of static mixer insertion tubes

The process in use involves static mixers manufactured by a certain manufacturer; I’m wondering if there could be issues with the welding of their insertion tubes Isn’t it similar to connecting the main pipes and branch pipes? He just welds them on the outside; I’m worried that the strength might not be sufficient. Is there anyone knowledgeable about this, or are there any standards or sources where I can look up information?
The welding of the insertion tube in static mixers indeed requires sufficient strength to prevent issues such as breakage during use. Generally, manufacturers operate in accordance with relevant welding standards and specifications, such as GB/T 985.1 \"Basic forms and dimensions of weld grooves – Part 1: Shielded metal arc welding, gas shielded welding, oxy-acetylene welding, and submerged arc welding\", to ensure welding quality. If there are concerns, you can ask the manufacturer to provide a test report on the welding quality, or conduct non-destructive testing (such as ultrasonic testing) to verify that the strength of the welds meets the required standards. At the same time, during engineering design, the load and operating conditions of the static mixer should also be taken into account to select appropriate welding methods and reinforcement measures. .
As can be seen from the picture, the groove wasn’t cut properly; how can quality be ensured in such a situation?

It is necessary to know the process parameters of the pipeline: operating pressure and temperature, as well as the properties of the medium, in order to determine whether there are any issues with branch pipe welding and whether it is feasible. I work in the pipeline industry; you can add Chuan You.
