Product Features
* High corrosion resistance and Heat
Resistance
- High corrosion resistance and heat
resistance make the stainless steel
pipes usable under many different working
conditions in chemical plants.
* Consistent Quality
- Stainless steel pipes are produced
using TIG and plasma welding up to 400A,
which is not available at other plants
in Korea. Large-diameter steel pipes
of 450A~1200A are produced by the roll
bender system.
* Superior internal bead treatment
- The cold rolled system, which is the
most advanced system to date, is used
to eliminate inner beads, thereby improving
the microstructure of welded areas.
* Advanced Technologies
- U-tubes for nuclear power, which had
previously always been imported, were
successfully developed by SeAH, and
are now being distributed to KEPCO and
other customers.
* Strict Quality Control System
- Pipe production facilities specially
designed by SeAH and its computer-aided
cutting system are contributors to the
manufacturing of high-precision products.
