Scope

This standard specifies the terms and definitions, classification and code, size, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certification of hot-dip coated steel sheets and strips for bellows (hereinafter referred to as steel sheets and strips). Book. This standard is applicable to corrugated steel structures with a thickness of 0.7 mm to 10 mm for hot-dip coated steel plates and steel plates used in the manufacture of pipe networks, culverts, underground water storage tanks, pedestrian passages, automobile underpasses, public pipe galleries and structures of special shapes installed on site. bring. Note: Under various service conditions, the bellows corrugation type, steel plate thickness and strength, foundation and backfill type, factory manufacturing control and installation, etc. should be reasonably designed according to the bearing load of various bellows. For corrugated steel pipes in different use environments, the type of coating and the weight or thickness of the coating should be reasonably selected according to the actual environment and service life requirements.
