When the pressure vessel is a product of the pressure vessel, we should make the welding test board. This requirement is not very strict, so the basic reason is that the domestic standard requirements for the ring test board is not strict

When there is a need to test the impact of the product board, the ring can not be linked to the words to do. All conditions can be exempted

Longitudinal weld force is two times of the force of the ring:

R- cylinder radius
L- cylinder length
P- container pressure
A- cylinder wall
