It is a most commonly used and highly-constructable joining device that places a watertight gasket around the outer surface end of recorrugated steel pipe and covers it with a coupling band by bolt-joining
It is a joining device for corrugated steel pipes with small nominal diameters such as 0RS and ORS perforated pipes. It is a simple connection device that inserts the sleeve into the inner diameter of the steel pipe end that has not been recorrugated and joins the outer surface with heat shrinkable tape.
It is a flange-type joining device mainly used in unique environments that require high watertightness. After joining the flange around the outer surface end of the steel pipe that has not been recorrugated with bolts, it is secured by inserting a watertight ring into the inner diameter.
It consists of a flange body and a sleeve, and the details are as follows.
It is a connecting component used in sections where connecting diameter between corrugated steel pipes changes, branch pipe is built, etc.
The angle of connecting pipe and branch pipe, the nominal diameter and length of main pipe and branch pipe are manufactured in consultation with clients.
