SIMULASI PENGENDALIAN KUALITAS PENGARUH DEFORMASI MATERIAL CONDENSER TUBE TERHADAP PROSES TUBE EXPANDING WATERBOX CONDENSER (STUDI KASUS DI PT. BBI PASURUAN)
ABSTRACT: Leakage tube after
tube expanding process is still occurred in PT. BBI Pasuruan due to imperfect
material deformation. Material deformation cause by a change in material form
due to external forces such as temperature, friction force, compressive force,
and the torque style. Deform 3D was used in this investigation to determine the
material deformation processes. Taguchi method design of experiment was also
used to minimize the bad cause of the poor performance is also influenced by
several variables or factors on the characteristics of the desired quality. The
results shows that the combination to prevent deformation of the material in
the condenser tube are the friction between the tool and the tube expander of
0.787 inch, the material used is stainless steel ASTM A 249 grade 2, tube
expanding process temperature optimum of 89.6 F, and expander velocity of 0.708
inches per second.
