The SIA Wb joint primarily includes the bell, spigot, and retaining ring. The end of the bell extends radially inward to form a complete annular wall, and the end of the spigot is equipped with a spigot projection (welding ring). The retaining ring consists of multiple rings and rubber supports.

The end of the bell extends radially inward to form a complete annular wall, and the end of the spigot is equipped with a spigot projection (welding ring). The retaining ring consists of multiple rings and rubber supports. The retaining ring has fixed holes to secure the rubber supports. The SIA Wb joint ductile iron pipe is a slip-in flexible self-anchored joint ductile iron pipe, with a self-anchoring chamber and a sealing chamber in the bell, and a welding ring at the spigot end. This joint pipe achieves self-anchoring by bearing axial forces. The pipe's specification range is from DN300 to DN1200.
