Flangeless connection of high-density polyethylene pipes and stainless steel pipes reduces the risk of leaks! A mechanical joint that eliminates the need for threading or electric fusion work!
No disassembly required, easy connection! The mechanical joint series "Suppon Joint"! Suppon MPX is a mechanical joint that allows pipe connection simply by inserting and tightening high-density polyethylene pipes (ISO outer diameter). It eliminates the need for an in-core, disassembly, and electric fusion work, enabling smooth construction operations. When switching from high-density polyethylene pipes (ISO outer diameter) to stainless steel pipes is necessary, the "Suppon MPX MP-V (for SUS)" comes in handy. On the high-density polyethylene side, there is no need for electric fusion work, allowing for immediate water flow and a reduction in construction time. On the stainless steel pipe side, there are no threading or flange welding tasks due to mechanical joining. Since the pipe type switching section is not a flange connection, the risk of water leakage from the flange area is also reduced, making it excellent for safety aspects such as earthquake resistance. It is also possible to slide along the pipe, making it easy to connect existing and newly installed pipes. If disassembly is required, it can be easily removed by simply loosening the installed bolts and nuts. Please give it a try when connecting different types of pipes, such as high-density polyethylene pipes (ISO outer diameter) and stainless steel pipes.
