The medium is toxic, flammable, and corrosive; can reinforcement rings still be used for opening reinforcement?

The last edit to this post was made by jizhanwei22 on 2016-6-12 at 08:59. Whether a pressure vessel can be strengthened using reinforcement rings depends mainly on the following factors: 1. The material of the vessel’s main body； (High-strength steel and CrMo steel do not allow reinforcement using gussets.) 2. The thickness of the gusset must be more than 1.5 times the wall thickness of the container shell ； (Not allowed) 3. Wall thickness of the container shell ≥ 38 mm ； (Not allowed) 4. The toxicity level of the medium in the container is extremely high and hazardous ； (Not allowed) 5. Class III pressure vessels with a design pressure of ≥4 Mpa ； (Not allowed) 6. Fatigued container ； (Not allowed) The original poster did not provide detailed parameters, so a detailed answer cannot be given. But the original poster can refer to the above points to determine whether reinforcement rings can be used for reinforcement.

In addition to the three conditions strictly specified in GB150, the scope of application for reinforcement rings should also be considered comprehensively, taking into account factors such as material, temperature, pressure, and structural design. There are many questions similar to the one posed by the original poster. Sometimes, we designers refer to the standards; if the reviewers suggest eliminating the reinforcement ring structure, we designers will ask, \"Which provision in the standards prohibits its use?\" ”Wait, what really needs to be done is a comprehensive consideration; the standards represent only minimum requirements, and they cannot be applied in their entirety. For propylene as the medium, I’m not sure if there is hydrogen sulfide present, and whether post-weld heat treatment is required In some facilities, the use of reinforcing rings is heavily restricted; for example, it is best not to use reinforcing ring structures in heat treatment equipment.
