expansion joint

1. Does selecting a standard expansion joint include shaped thinning? For example, if DN300 has a δ of 4 mm, how thick should the material cut be? 2. When selecting a standard expansion joint to meet the design requirements, should one choose one with a higher stiffness value or not?
It’s not enough to make a choice based on standards; actual calculations are necessary to know for sure. The minimum thickness after molding can be determined only after calculation. The feeding thickness and the nominal thickness specified in the drawings are determined based on the amount of thinning, which should ideally be established based on the experience of the expansion joint manufacturer.
Choose a standard expansion joint with a thickness of 4 mm; is it necessary to use software to calculate the minimum thickness as well?
The key is whether all the parameters of your equipment, such as pressure, temperature, and materials, meet the standards If the requirements are met, the standard thickness is generally considered to be a lower value; you need to take into account that the actual thickness used in manufacturing will certainly not be 4 mm.
1. Includes thinning thickness. 2. Choose the lower one.
