Supposedly soda bottles fail at around 150psi. They're over-engineered as regular pressure from the carbonation is around 50psi. If you leave one in a hot car it can reach 100psi. 5kg/cm2 converts to about 71psi which is fairly close to the standard working load they're under at the bottling plant so I wouldn't worry about that too much. Now, the psi that Chinese-made setup can handle is another matter but I wouldn't worry about the bottle exploding.
