Regarding the question of whether welding is required where the reinforcement ring passes through the weld seam
Thread Content
Hello sea friends! Is it necessary to weld the tank reinforcement ring when it passes through the wall plate girth weld? Also, does the pipe reinforcement ring need to be welded across the pipe weld? Which specification can provide effective theoretical support? Please see the picture, thank you!
From the perspective of the role of the reinforcing ring, it should be welded
OK, thanks for the reply. Is the weld overlap appropriate?
Without closed welding, how to ventilate and check the welding quality of the reinforcing ring?
There is a problem with the design of this reinforcement ring. The design layout at least does not take into account this reinforcement ring. Generally, the radius of the reinforcement ring can be increased, and then the welds can be staggered. If it is a general storage tank, the welds can be covered, but remember the requirements before covering: 1. 100% radiographic inspection 2. Polishing
Your answer is very comprehensive. It is indeed possible to weld, but there are prerequisites. At present, the circumferential weld has not been subjected to non-destructive testing or smoothing, which is embarrassing. It is difficult to decide whether it should be welded or not. This storage tank is a chilled water storage tank, the detection ratio is not high, and the detection does not cover this area. The storage tank will need to be kept cold later.
Cover the weld and pass the non-destructive test, the surface is smoothed, and the reinforcing ring weld needs to be welded!
The reinforcing ring has no leak detection holes, the fit of the reinforcing ring is not good, and the welding seam at the covered position of the cylinder is not smoothed... As for the coverage of the fillet weld and the circumferential seam, the circumferential seam is the main weld, and theoretically the welding seam should not be covered on it.
I misread it. There seems to be a leak detection hole, but it's just not at the lowest point, right?
