Estimated useful life: rubber joint

Estimated useful life: rubber joint

Calculate the estimated useful life based on usage conditions! Please use it as a guideline for regular inspections and replacement timing.

The "rubber joint" is made of organic materials such as rubber and synthetic fibers, so it has a limited lifespan. Additionally, its lifespan can vary significantly depending on the usage conditions. By downloading the PDF document, you can view the "Service Life Coefficient Table" and the "Pressure Unit Conversion Table." Please use these to estimate the expected service life based on your usage conditions, as a guideline for regular inspections and replacement timing. The standard service life is set assuming the fluid is water. *For more details, please refer to the PDF document or feel free to contact us.*

Inner and outer coated steel pipe × cast iron pipe, dissimilar pipe joint, Suppon MD joint.

Inner and outer coated steel pipe × cast iron pipe, dissimilar pipe joint, Suppon MD joint.

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.

High-density polyethylene pipe (ISO) × SUS pipe Supon MPX MP-V

High-density polyethylene pipe (ISO) × SUS pipe Supon MPX MP-V

Flangeless connection of high-density polyethylene pipes and stainless steel pipes reduces the risk of leakage! A mechanical joint that eliminates the need for threading or electric fusion work!

No disassembly required, easily connectable! The mechanical joint series "Suppon Joint"! Suppon MPX is a mechanical joint that allows for pipe connection simply by inserting and tightening high-density polyethylene pipes (ISO outer diameter). It eliminates the need for core drilling, 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 reducing 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 flange-connected, the risk of water leakage from the flange section 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 needed, 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.

PVC pipe × water supply steel pipe dissimilar pipe joint Suppon M joint

PVC pipe × water supply steel pipe dissimilar pipe joint Suppon M joint

PVC pipes and steel pipes can be connected without flanges! No need for flange processing or welding of steel pipes, achieving simplified construction and cost reduction!

No disassembly required, easy connection! Introducing the "Suppon Joint" series of mechanical connection fittings! The product we are introducing this time is the "Suppon MVD." It is a fitting that allows for the connection of PVC pipes and water supply steel pipes. The connection part for the PVC pipe does not require solvents, so there is no need for drying or curing, allowing for immediate water flow after connection. Additionally, it can be installed even if the construction area is wet due to residual water in existing pipes. The connection part for the steel pipe uses mechanical joining, eliminating the need for threading or flange welding. Installation can be done immediately after cutting the steel pipe. Since the pipe type transition section is not a flange connection, the risk of leakage from the flange area is 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 new pipes. This can be utilized when repairing or renovating aging piping systems to connect with existing pipes. If disassembly is needed, it can be easily removed by simply loosening the installed bolts and nuts. Please give it a try when connecting PVC pipes and water supply steel pipes!
