On the design of fittings with jackets

When designing a jacketed fitting, the following key points should be considered: 1. Fitting bending radius: The bending radius of the fitting should be greater than or equal to three times the diameter of the fitting, which ensures smooth flow of fluid within the pipe and reduces pressure losses. 2. Welding method: A full weld is typically used between the pipe fitting and the tank body to ensure the sealing of the connection as well as the stability of the structure. The welds must be welded evenly to avoid welding defects such as pores and cracks. 3. Inspection: After welding is completed, non-destructive testing such as X-ray inspection or ultrasonic testing should be carried out to ensure that the welds are free of defects such as cracks and pores. At the same time, a hydrostatic test is conducted on the piping system to verify its pressure resistance and sealing performance. 4. Jacket section: Ensure that the jacket fits well with the main pipeline, and the inlet and outlet of the jacket should be positioned appropriately to facilitate the entry, exit, and circulation of the medium. The design of the jacket should also take into account the effects of thermal expansion and contraction on the pipes and the tank body. The above are the basic requirements for the design of jackets on piping. For specific design work, detailed design and calculations must be carried out based on actual operating conditions and usage requirements. .
