40、ding from end to end of each length of pipe. As there are important differences in the structuralcharacteristics of annular, riveted pipe versus helical pipe, it is important for the purchaser to stipulate, for Type I and Type II pipe,the method of fabrication desired. If the method of fabrication i

41、s not stated in the ordering information, the fabrication method shallbe at the option of the fabricator.7.1.2 Type IApipe shall be fabricated with a smooth liner and helically corrugated shell integrally attached at helical lock seamsextending from end to end of each length of pipe. The shell shall

42、 have corrugations of nominal 223 (or 3 in. 68 or 75 mm 75 mmpitch.7.1.3 Type IR pipe shall be fabricated with helical ribs projecting outward with a continuous lock seam extending from end toend of each length of pipe.7.2 CorrugationsThe corrugations shall be either annular or helical as provided i

43、n 7.1. The direction of the crests and valleysof helical corrugations shall not be less than 60 from the axis of the pipe for pipe diameters larger than 21 in. 525 mm, 525 mm,and not less than 45 from the axis for pipe diameters of 21 in. 525 mm 525 mm and smaller.7.2.1 For Type I and IA pipe, corru

The dimensions of thecorrugations shall be in accordance with Table 1 for the size indicated in the order.B745/B745M 1537.2.2 For Type IR pipe, the corrugations shall be essentially rectangular ribs projecting outward from the pipe wall. Thed

45、imensions and spacings of the ribs shall be in accordance with Table 2 for the size indicated in the order. See also Fig. 1. Forthe 1112 in. 292 mm rib spacing, a stiffener shall be included midway between the ribs, if the sheet between the ribs does notinclude a lock seam. This stiffener shall have

46、 a nominal radius of 0.25 in. 6.4 mm and a minimum height of 0.20 in. 5.1 mm5.1 mm toward the outside of the pipe.NOTE 1The nominal dimensions and properties for smooth corrugations and for ribs are given in Practice B790/B790M.7.3 Riveted SeamsThe longitudinal seams shall be staggered to the extent

47、 that no more than three thicknesses of sheet arefastened by any rivet. Pipe to be reformed into pipe-arch shape shall also meet the longitudinal seam requirement of 8.2.2.NOTE 2Fabrication of pipe without longitudinal seams in 120 of arc, so that the pipe may be installed without longitudinal seams
