To provide a method for restoring and correcting a closed type drum can so that it can be used for a long time, which is characterized by restoring deformation such as a concave shape and correcting it to a normal shape to extend its life.

かに補修して、両用に適する状態とし度い次第である。``Conventional technology'' Conventionally, many drum cans were made of iron, which were cheap and had a short service life, and the body side often suffered concave deformations due to impact against other objects during use. In such cases, the oven-type drum can must be repaired by inserting a device inside and manually hammering it back.The closed-type drum can cannot easily be repaired, and the iron-made one is cheaper and has a shorter service life. However, recently stainless steel drums have come into widespread use, and as they have a service life of up to 15 years and are expensive, they are prone to colliding with other objects during use. If it is deformed into a concave shape, it is important to repair it as soon as possible and make it suitable for both uses.

This is to restore and repair deformations such as.

This method rapidly injects water under pressure of approximately g/cnl, and as a result of this, the concave and deformed parts of the body plate, etc., receive stronger pressure than other parts, are pressed, and can be restored to shape. Small-sized deformations in the shape of proximal concave and convex portions are also restored in association at the same time, so that they are correctly restored to their original shape.

The service life of the drum is approximately 15 years, but the repair according to the present invention extends the service life by an additional five years, which is particularly effective for expensive stainless steel drum cans.
