DESCRIPTION

This CCPA standard specifies the classification and marking, general regulations, technical requirements, testing, inspection rules, identification, packaging, transportation and storage, and product qualification certificate of base shaped reinforced concrete pipes.

This CCPA standard is applicable to base shaped reinforced concrete pipes used for gravity flow pipelines such as rainwater, sewage, water diversion, and farmland drainage and irrigation that use slotted construction. The production of base shaped reinforced concrete pipes for other purposes (such as comprehensive pipe galleries, underground pipeline tunnels, etc.) can be carried out according to this standard.
