OCTG, ordinary and general structural purpose pipe which are produced with the best
technology, with a diameter ranging form
1/2” to 8”, are precisely formed, welded
with high-frequency electric resistance and
cooled by Kumkang Kind’s advanced computerized system and they are inspected
rigorously through various test such as highpressure and non-destructive tests. This is
why we can say Kumkang Kind stands as the
reference in the steel pipe industry!

KUMKANG KIND STEEL PIPE
PRODUCT DESCRIPTION
Exporting
Hot
Galvanized
As Kumkang Kind steel pipes are exported to various countries
around the world, we conduct rigorous quality control on our pipes,
This is why Kumkang Kind is renowned for its accurate delivery of
quality steel pipes.
Used for ordinary piping, pressure service, fuel gas piping or general structural piping, its zinc galvanized coating gives it an elegant
external finish and a strong rustproof effect.
Black
Steel Pipe
Used for ordinary piping, pressure service, fuel gas piping or general structural piping, it is very effective for industrial water, vessels, transportation of oil, fire hydrant pipes and structural parts
of cars, machines, public works, steel towers and props.
Conduit
Pipe
Used to protect electric wires, the hot dipped galvanized conduit
pipe’s durability has been drastically extended and, because of the
sockets at each extremity, the work at the job site is easier than
ever.
Steel
Square
Primer
Coated
Kumkang Kind has a special steel square production line that produces various sizes and satisfies the most stringent customer demands for their structural pipes for construction.
The primer coated pipes are coated with rust-proof material which
provides excellent durability. Very easy to work with at the job site,
it reduces labor and production costs and is widely used to reinforce the interior and exterior of buildings and also for parking
facilities.
