At Daihan Anchor Chain Mfg Co Ltd, each employee is dedicated to making the very
product possible through technological competitiveness
and strict quality management.
ΆΓ Flash butt welding
Regular calibration of high-quality welding machine(ESAB)
and standardization of optimum welding conditions have contributed
to quality enhancement on the welding line. The results of
welding operations for chain cables are automatically recorded on
the computer zip drive for perfect product traceability.
The continuous quenching/tempering furnace uses an automatic
PID method to maintain temperatures at optimum levels.
During quenching, water temperature is maintained below the
fixed level by strong agitation, and sufficient tempering
improves product quality.
ΆΓ Fatigue life test
Because of the long functional life of chain, especially offshore
mooring chain, its fatigue life span is critical to its performance.
In order to make effective improvements in chain's fatigue
life, Daihan Anchor Chain Mfg Co Ltd, in cooperation with KIMM, performs a full-scale
fatigue test for evaluation of each chain life..
ΆΓ Corrosion test
In cooperation with steel manufacturers and research institutes,
we are also performing a cooperative study on the effect of
seawater on corrosion of offshore mooring chain ΆΓ NDT Method
DaiHan Anchor Chain Mfg Co Ltd continues to make technical developments for the NDT-line
through collaboration with NDT makers and research institutes
to obtain product reliability for our customers..
ΆΓ Studless Chain
Studless link chain meets the same stringent quality standards
as stud chain in terms of proof & breaking strength, mechanical
properties, and fatigue life. Since tasks of stud inserting
and stud welding are excluded from its manufacturing process,
less stress is generated and life span is prolonged.
