The structural design of chemical container design involves the factors of chemical process, material, manufacture and corrosion protection, etc., harmonic shG-32-50-2UH in chemical container manufacturing, and the structural analysis is carried out only from the Angle of stress and strength. From the perspective of stress and strength, it is necessary to consider how to reduce local stress. The larger the volume of the container is, the higher the pressure is, the more careful consideration should be given to reduce local stress in structural design. Even destroy the entire equipment.

The principle measures to reduce local stress in structural design are as follows:



C1) Transition as smoothly as possible at structural discontinuities. And should avoid the weld.



(2) where there is local load, it should be properly damped, such as lining plate to reduce local stress. The discontinuous stress always exists at the tangent line of the connection between the head and the cylinder of the disc, oval or spherical head
