Scope This Japanese Industrial Standard specifies corrugated steel pipes and sections, and bolts, nuts, washers and coupli
3、ng bands for joints for the use of water channel, passageway and other various constructions. Remark: The corrugated pipes include those of the spiral type which are made in advance in the form of pipe by the manufacturer and those which are shipped as the sections from the manufacturer and assemble
4、d at the construction site. 2. Class and Symbol The classes and symbols of the corrugated pipes according to combination of sectional shapes and corrugation shapes of the pipes shall be as given in Table 1.

Jointing of the sections is of the lap type both in the axial direction and in the circumferential direction. Spiral
8、pipes are connected by the coupling band. Jointing of the sections is of the lap type both in the axial direction and in the circumferential direction. Remark; When the material contains copper, “Cu“ shall be suffixed to the symbol. Examples: SCP 1 RSCu, SCP 3 RSCu 3. Manufacturing Method The corrug
