Drainage joint for buried pipes in bathroom slabs

Abstract

This item is a drain joint connected to a drain pipe buried in a bathroom slab. It is an insert-type drain joint (drain joint) that allows for the connection of existing iron pipes buried in the concrete slab used as bathroom drains in old housing complexes and old reinforced concrete houses to currently commonly used polyvinyl chloride (PVC) pipes. As shown in the "Reference Top Perspective View Showing the Names of Each Part," this item consists of a thin pipe, a thick pipe, and a flange. As shown in "Reference Diagram 1 Showing Instructions for Use" and Figure 2, the thick pipe of this item is designed to be inserted into an existing iron pipe, while the thin pipe allows a PVC pipe to be directly inserted. The PVC pipe is bonded to the thin pipe, and the flange is also fixed to the floor with glue, ensuring a secure connection and stable retention.
