DB stands for various terms. Discover the full forms, meanings, and possible interpretations of DB across different fields and industries.
Double Bell (DB) refers to a specific type of pipe connection where both ends of a pipe segment are flared or expanded, resembling bells. These bell-shaped ends are designed to accommodate spigot ends of adjacent pipe sections, allowing for a secure, push-fit connection using gaskets or sealing rings. Double bell pipes are commonly used in the installation of ductile iron, PVC, and concrete pipelines for water, sewage, and drainage systems. This design eliminates the need for additional couplings, making installation faster and reducing material costs.
The DB configuration is particularly favored in long pipeline runs where multiple segments must be joined efficiently and with minimal leakage risk. The symmetrical structure also allows for versatile installation, as either end can receive a standard spigot pipe. These connections offer a reliable seal under pressure and are often used in buried applications where long-term durability and leak prevention are critical.
