MD joint for inner and outer coated steel pipes (PD and VD steel pipes)

The MD joint for internally and externally coated steel pipes (PD and VD pipes) is a mechanical joint that does not require disassembly. It can be connected simply by inserting the pipe and tightening the bolt and nut, with no need for pre-treatment such as threading or coating removal.

Internal and external coated steel pipe fittings - Suppon MD joint

No need for coating removal or threading work on the inner and outer coated steel pipes! A convenient mechanical joint that does not require disassembly, featuring a disengagement prevention function and high water tightness.

No disassembly required for connection! Introducing the "Suppon Joint" series, a mechanical joint method that only requires insertion and tightening! The Suppon MD Joint is a mechanical joint characterized by its ability to be installed without removing the outer coating of 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 exceptionally user-friendly. It accommodates internally and externally coated steel pipes with diameters ranging from φ40mm to 150mm. It is also possible to slide along the pipe, making it easy to connect existing and newly installed pipes. This can be utilized for repairs or renovations of aging piping systems at the connection points with existing pipes. There is no need for traditional flange welding or screwing tasks, eliminating the need for conventional flange connection work. Flangeless connections reduce the risk of water leakage from the connection points and are expected to enhance seismic resistance. Additionally, we offer a variety of options for connecting different types of pipes, allowing for a change in pipe type with just one joint. If disassembly is required, it can be easily removed by simply loosening the installed bolts and nuts, making it useful as a fixture for piping tests using water pressure or air.

High-density polyethylene pipe (ISO) × steel pipe Suppon MPX MP-V

Switching pipe types with flange-less connection of steel pipes and high-density polyethylene pipes! No flange processing or welding work required for steel pipes, simplifying construction and reducing costs!

No need for disassembly, easy connection! Introducing the "Suppon Joint" series of mechanical joint methods! The "Suppon MPX MP-V" joint is useful when switching from high-density polyethylene pipes (ISO outer diameter) to steel pipes. On the high-density polyethylene side, there is no need for an in-core, disassembly, or electric fusion work, allowing for smooth construction operations. Since there is no cooling time, water can be passed through immediately, significantly reducing construction time. Additionally, on the steel pipe side, mechanical joining eliminates the need for threading or flange welding. Construction can begin immediately after cutting the steel pipe. Since the pipe type switching section does not involve flange connections, the risk of leakage from the flange area is reduced, enhancing safety in terms of earthquake resistance and other factors. It is also possible to slide along the pipe, making it easy to connect existing and newly installed pipes. This can be utilized for repairs or renovations of aging piping systems at the connection points with existing pipes.

High-density polyethylene pipe (ISO-P) fittings Supon MPX

No need for electric fusion work! Easy installation with just one wrench, even in wet conditions or rain! No need to prepare fusion machines or generators, reducing total costs!

No disassembly required, easy connection! Introducing the "Suppon Joint" series of mechanical joints! Suppon MPX is a mechanical joint that allows for the connection of high-density polyethylene pipes without the need for an inner core or disassembly. The mechanical method involves tightening bolts and nuts with a wrench to connect high-density polyethylene pipes. Since there is no need for electric fusion work and no cooling time required, water can be flowed immediately, significantly reducing construction time. The advantage of the mechanical method in terms of construction is that it can be performed regardless of the location or weather conditions. Even in water areas where groundwater may emerge after excavation or during bad weather when fusion work cannot be done, construction can proceed without these concerns. The elimination of the need for equipment such as fusion machines or generators also leads to cost savings. Additionally, the Suppon MP joint offers a wide range of options. We have various lineups for connecting different types of pipes, allowing for a change in pipe type with just one joint. It is also possible to slide along the pipe, making it easy to connect existing pipes with newly installed ones. This can be utilized in the repair or renovation of aging piping systems at the connection points with existing pipes. Please give it a try when connecting high-density polyethylene pipes.

PVC pipe × coated steel pipe, dissimilar pipe joint, Suppon MD joint

PVC pipes can be connected to coated steel pipes with just one joint! No need for tedious coating removal work, significantly reducing construction time!

No disassembly required for connection! Introducing the "Suppon Joint" series of mechanical connection methods! The product we are introducing this time is the "Suppon MD-V." It is a joint that allows for the connection of PVC pipes and internally and externally coated steel pipes. Since the connection part of the PVC pipe does not use solvents, there is no need for drying or curing, and water can flow immediately after connection. Additionally, it can be installed even if the construction area is wet due to residual water in the existing pipes. The connection part of the internally and externally coated steel pipes (VD pipes and PD pipes) can be installed without removing the external coating. Moreover, it can be joined without disassembly, and installation can be done with just a torque wrench, making it extremely user-friendly. It is also possible to slide along the pipe, making it easy to connect existing and new pipes. This can be utilized for repairs or renovations of aging piping systems when connecting to 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 PVC pipes and internally and externally coated steel pipes.

[New Proposal] Installation of Shut-off Valves and Fire Hydrants - Suppon MPX

Realization of flange-less seismic-resistant piping! Installation of shut-off valves and fire hydrants on high-density polyethylene piping can be done using mechanical methods!!

The Suppon MPX soft seal valve with base is an integrated soft seal partition valve equipped with a mechanical type receiving port. The Suppon MPX MP-TF base for fire hydrants makes it easy to install fire hydrants and air valves, and the base improves stability. Due to the lack of flanges, no joining materials (gaskets, bolts, nuts) are required, leading to cost reduction and a decrease in the risk of leaks by reducing connection points. Thanks to the mechanical receiving port structure, there is no need for specialized fusion machines, clamps, generators, or other equipment, allowing for immediate water flow after installation regardless of site conditions such as water locations or weather, thus shortening construction time. The diameter ranges from 50mm to 200mm, and there is a rich lineup that allows for connections with different types of pipes. There is also a lineup of Suppon MPX MP-BF bases for fire hydrants designed for the ends of pipelines.
