Tongue And Groove Cement Pipe Mold

A tongue-and-groove joint uses a curved tongue on one pipe end running into a matching groove on the next, which distributes load around the circumference better than a flat face and allows the joint to flex slightly under settlement. This mold forms the tongue and the groove to one joint drawing, including flexible tongue-and-groove versions where the profile carries a sealing element. On the same tooling family the workshop also produces box culvert molds, which use the same shell-and-end-ring logic for rectangular sections. Pipe diameter, length and profile are To Be Confirmed per specification.

We machine the tongue radius and groove depth to the joint drawing you confirm and fit them to shells cut to the pipe drawing, so the curve is set by the drawing rather than by an operator's hand. Flexible-joint pipe keeps the same working gap from set to set.
