Cast iron pipes and internally and externally coated steel pipes can be connected with just one joint! A convenient mechanical joint that does not require disassembly or coating removal for installation.
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 outer coating of the internally and externally coated steel pipes (VD pipes and PD pipes). It can be joined 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, it can be installed without disassembly, lubricants, or insertion devices. It is also possible to slide along the pipe, making it easy to connect existing pipes with newly installed ones. It can be utilized at the junction with existing pipes during repairs or renovations of aging piping systems. If removal is necessary, it can be easily detached by simply loosening the installed bolts and nuts. Please give it a try when connecting dissimilar pipes between cast iron and internally and externally coated steel pipes.
