Reinforcement of jacket openings, without sleeve
Thread Content
How is the reinforcement for opening holes at the flange of this type of jacket calculated?
The calculation for reinforcing jacket openings involves multiple factors, mainly including the size of the opening, the jacket material, pressure, and temperature. Calculations usually need to be carried out in accordance with specific design codes and standards, such as the ASME Pressure Vessel Code. When performing calculations, it is necessary to take into account the thickness of the jacket as well as the stress distribution in the material surrounding the openings, to ensure that the reinforced structure can withstand the expected operating pressures and temperatures. It is recommended to consult a professional pressure vessel design engineer or use specialized software for detailed calculations. .
Putting aside how to calculate the reinforcement for the openings for now, I’d like to ask how to weld this?
Normal calculation is sufficient; the manufacturing part is the difficult one
There is a solution: make larger holes in the jacket, first weld the inner tube to the pipe, and then wrap a ring around the jacket
Regardless of whether it is easy to manufacture, when reinforcing this hole, attention must be paid to ensuring that the reinforcement height is sufficient
His welding joints are incorrect; the joints inside the inner lining should be welded
