The shell of the carbon steel tube heat exchanger is a kind of container. The main contents and methods of chemical container structural design are also applicable to the design of cylindrical equipment such as evaporators, towers, and dryers. The basic requirements for its design are as follows:
1,strength
Strength refers to the ability to withstand damage from external forces. The designed container must have some strength to ensure production safety.
2, stiffness
Stiffness refers to the ability of a component to resist deformation due to external forces. The container must have some stiffness to avoid impermissible deformation during installation, transportation, and use. Severe deformation will cause the equipment to be scrapped.
3,stability
Stability is the ability of a grooved piece to maintain its original shape under the action of external forces. If the stability of the carbon steel tube heat exchanger is not good, it will be crushed or wrinkled under the action of external forces.
4, durability
Containers should have a long service life. Durability determines whether the material selection is appropriate, whether the anti-corrosion measures and construction are correct, and the corrosion of the material by the medium.
5, air tightness
Carbon steel tube heat exchangers that are under pressure or handle toxic media should have good air tightness to provide a good working environment and maintain normal operating conditions.
6, save materials, facilitate manufacturing, and facilitate transportation, installation, operation and maintenance.
