Fittings for high-density polyethylene pipes (ISO outer diameter) for SKXISO-P.

Fittings for high-density polyethylene pipes (ISO outer diameter) for SKXISO-P.

Significant reduction in construction time is possible with mechanical construction methods! No electric fusion work required, making it easy to install joints in wet areas and tight spaces!

SKX is the industry's first joint that does not require disassembly and can be installed using a short wrench. It is ideal for connecting to existing pipes in renovation work for buildings such as apartments. The connection of high-density polyethylene pipes is a mechanical connection rather than a fusion connection, significantly reducing installation time. Since it can be installed with fewer tools, total costs can also be reduced. Water can be run immediately after connection. The low tightening torque allows for installation with short tools like a short wrench, enabling time savings and installation in tight spaces. It can also be installed in sites with water accumulation, such as spring water, as electric fusion work is not required. There is also a rich lineup of products including diameter-differing sockets, elbows, tees, male-threaded sockets, and female-threaded sockets.

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

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. If removal is necessary, it can be easily done by simply loosening the installed bolts and nuts. Please give it a try when connecting dissimilar pipes between high-density polyethylene pipes (ISO outer diameter) and steel pipes.

Fluid equipment piping components pipe fittings

Fluid equipment piping components pipe fittings

"Connecting thoughts, changing the flow" – possibilities expand from just one joint!

The fittings mainly referred to as elbows serve the purpose of changing the direction of fluid (gas or liquid) flow. Depending on the usage, they are classified into three types based on the angle of bend: 45°, 90°, and 180°. Additionally, fittings known as tees and wyes have the function of branching or merging the flow of fluid. Nipples and sockets are used to connect fittings of the same diameter or to extend lengths, while reducers and bushings connect fittings of different diameters, allowing for the expansion or reduction of pipe size. Fittings such as caps and plugs function to stop the flow of fluid by sealing the ends of pipes. Fittings also have other roles, such as transmitting mechanical power and absorbing vibrations or thermal expansion.
