This Standard specifies minimum requirements for the materials and manufacture of buried metal pipe formed using sinusoidal profile strip. The pipe is full circular shape formed by a continuous helical lock-seam that runs helically to the longitudinal axis of the pipe.
Pipe diameters up to and including 3600 mm are covered.
Sinusoidal profiles covered include the following:
(a) S38 (pitch 38 mm).
(b) S68 (pitch 68 mm).
(c) S75 (pitch 75 mm).
(d) S125 (pitch 125 mm).
