Container
treatment describe step by step for five different types of repairs very common
to all steel components Container. Here we discuss about straightening method
which is the most economical method of repair.
Types of repairs
is most important:
When
determining which type of repair is appropriate for a component requiring
repair, should remember that what kind of repair methods are recommended.
Following terms of repair here (Marine Container Repair Procedure).
STRAIGHTENING:
Remember
that any dents or distortions whenever decided to straighten, repairer should
use hydraulic jack or mechanical means without heat. Sometimes it is need to
applying heat. When must be applying heat, the steel should only be heated in
the damaged area and corresponding to approximately 650°C (1200°F).
Never use any sharp or round head hammer to straighten. The complete repair must be cosmetically acceptable.
When straighten panel,
including side, front, roof, and door panels, following precautions should be
observed...
Tools used for straightening:
*Flat hammer *Hydraulic
jack *Mechanical jack *Backing plate etc.
Straightening with
a jack:
During use a jack on the side panels, the opposite side of the container is normally used to support the jack. The base of the jack placed on a board of sufficient size and thickness across several corrugations to spread the load and to reduce the pressure in a area. This will prevent damage to the opposite side during the repair process.
Straightening with a flat hammer:
If a flat hammer and backing plate are used, the concave side (General Damage Measurement Concave) of the dent should be supported by the backing plate. The convex side of the dent is forced back into the flat surface of the backing plate using the flat hammer.
