Nowla construction method is inserting loose
flange to the pipe and, by using "tsubadashi" flanging
method, a next-generation flanging (processing the pipe edge
to the shape of brim), without changing the tube end of the
material of our original mother tube and join by bolt and nut.
Stability of quality, shortening the term of
works, and reduction in cost can be achieved as compared with
a current welding pipe connection method.
