3、 pipe and pipe-arches,ribbed and composite ribbed steelpipe,ribbed pipe with metallic-coated inserts,closed rib steelpipe,composite corrugated steel pipe,and steel structural platepipe,pipe-arches,and underpasses for use as storm sewers andsanitary sewers,and other buried applications.Ribbed andcomp
4、osite ribbed steel pipe,ribbed pipe with metallic-coatedinserts,closed rib steel pipe,and composite corrugated steelpipe shall be of helical fabrication having a continuouslockseam.This practice is for pipe installed in a trench orembankment and subjected to earth loads and live loads.Itmust be reco
5、gnized that a buried corrugated steel pipe is acomposite structure made up of the steel ring and the soilenvelope,and both elements play a vital part in the structuraldesign of this type of structure.This practice applies tostructures installed in accordance with Practice A798/A798Mor A807/A807M.1.2
6、 Corrugated steel pipe and pipe-arches shall be of annu-lar fabrication using riveted or spot-welded seams,or of helicalfabrication having a continuous lockseam or welded seam.1.3 Structural plate pipe,pipe-arches,underpasses,andarches are fabricated in separate plates that,when assembled atthe job
