Abstract

1285309 Sprinkler pipes SCHAUBSTAHL WERKE 21 July 1971 [29 July 1970] 34173/71 Heading F2P A sprinkler pipe which is perforated by pairs of elongate holes 5, 8 formed by pressing out, but not removing web 6, 9 of the pipe wall between parallel slits, has successive longitudinal portions 10, 7, 4 in which the elongate holes extend alternately in the axial direction and in the circumferential direction. Preferably the portion having circumferentially extending holes comprises from one to six parallel rows of holes and the holes in adjacent rows may be in off-set relationship e.g. by half a hole. The pipe may have screwed portions or flanges at its ends for connecting purposes (Figs. 1 and 2, not shown).
