Cast iron pipes and internally and externally coated steel pipes can be connected with just one joint! A convenient, non-dismantling mechanical joint that eliminates the need for coating removal work.

No disassembly required for connection! Introducing the "Suppon Joint" series, a mechanical joint method that simply requires insertion and tightening! The product we are introducing this time is the "Suppon MD-D." It is a joint that can connect cast iron pipes and internally and externally coated steel pipes (VD pipes and PD pipes). The Suppon MD Joint is characterized by its ability to be installed without removing the external coating of the internally and externally coated steel pipes (VD pipes and PD pipes). It allows for connection without disassembly, and installation can be done with just a torque wrench, making it extremely user-friendly. Additionally, the MD Joint can be used to connect cast iron pipes ranging from 75mm to 150mm. Even when connecting cast iron pipes, installation can be done without disassembly, lubricants, or insertion machines. It is also possible to slide along the pipe, making it easy to connect existing pipes with newly installed ones. This can be utilized during repairs or renovations of aging piping systems at the connection points with existing pipes. If removal is necessary, it can be easily detached by simply loosening the installed bolts and nuts. Please give it a try when connecting different types of pipes, such as cast iron pipes and internally and externally coated steel pipes.
