New joint is first of its kind to allow for
curved steel trenchless installation.
VANCOUVER, Wash., Nov. 15,
2022 /PRNewswire/ -- Northwest Pipe Company (Nasdaq:
NWPX), a leading manufacturer of water-related
infrastructure including engineered pipeline systems and
precast products, has developed the
Permalok® Radial Bending Joint (RBJ) that enables
steel pipe to be installed in a curved radius in
microtunneling applications.
This patent-pending technology is a ground-breaking advancement
in trenchless microtunneling construction. The Northwest Pipe
Company team developed the proprietary joint design to meet a
target radius curve of 800 feet during trenchless installation.
Permalok® steel pipe is most often used as a
casing pipe for utilities and excels in trenchless jacking
applications including microtunneling, pipe jacking, auger boring,
and pipe ramming. The press-fit machined joints reduce field time
by eliminating butt-weld joints and result in a shortened install
duration and reduced field costs. To solidify the joint's validity,
the Permalok® RBJ has undergone Finite Element
Analysis at the University of Thessaly Department of Mechanical
Engineering.
"This joint changes the way we have all thought of
microtunneling construction," states Scott Montross, President and Chief Executive
Officer of Northwest Pipe Company. "We have developed a solution
that enables steel pipe to curve during trenchless construction,
which makes microtunneling even more feasible in constrictive or
challenging environments. For years, trenchless applications have
been limited by a straight installation path—but not anymore."
The Company manufactures Permalok® RBJ in pipe
diameters varying from 30 to 156 inches. The actual curve radius is
dependent on site conditions as well as the pipe diameter and
length.
