on contents in the drum.

Appropriate torque is essential while screwing drum plug, excess or lack of
torque will lead to leaking risks of the container. After both drum flange and
plug are properly installed, it forms a sealing system for drum.

maintenance or replacement of insertion die is necessary to keep riveting

after riveting, need to be checked if problems occur.
