There will be no great disparity between the thickness of the tube and the tube: the tube details show that the pressure is relatively low, and it is strengthened with a reinforcing ring; For medium and heavy plates, reinforcing rings or forged tubes can be used. There is no specific limitation on the thickness of the forged pipe. Of course, this does not refer to the specific thickness. Designers will consider whether to increase the thickness of the cylinder or the thickness of the forged pipe according to experience.

Of course, the welding of the thick nozzle and the thin cylinder adopts plug-in structure, and the internal groove is used as far as possible to prevent the welding from falling down.
