PVC pipe × steel pipe dissimilar pipe elbow SKX
It is possible to connect PVC pipes and steel pipes with an elbow! Achieve easy installation without the need for adhesive application (for PVC pipes) or threading work (for steel pipes)!!
SKX is the industry's first hybrid pipe joint that does not require disassembly for installation and can be installed using a short wrench. When connecting PVC pipes, there is no odor generated since no solvents are used, and curing such as drying is unnecessary. Therefore, water can be passed through immediately after connection, allowing for a reduction in construction time. When connecting steel pipes, there is no need for threading the pipes, so installation can be done immediately after cutting the pipes. The low tightening torque allows for installation with short tools like a short wrench, enabling reduced construction time and work in tight spaces. It is equipped with a standard expansion and contraction flexible disengagement prevention feature, which absorbs vibrations in the piping around pumps. It is possible to connect different types of pipes, such as PVC and steel pipes, using elbows and tees, and there is a wide range of lineups and sizes available, including diameter-reducing sockets, male-threaded sockets, and female-threaded sockets.

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, 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 those concerns. The elimination of the need for equipment such as fusion machines and 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 and new pipes. This can be utilized for repairs or renovations of aging piping systems at the connection points with existing pipes. Please give it a try when connecting high-density polyethylene pipes.

Different types of aluminum joining methods
Very high fastening strength in one step! Fastening different aluminum materials that are difficult to weld without pre-drilling. No heat is generated, and it can be easily used by anyone.
Generally, it is said that welding aluminum plates of different types is difficult. Due to the differing properties of the 5000 series and 6000 series aluminum, welding is not easy. However, we will introduce a method that allows for easy fastening even under such conditions. 1. 'RIVSET' is a high-strength, reliable self-piercing rivet. It mechanically joins different types of materials easily without the need for a pre-drilled hole. It is also possible to fasten three or more materials. This product penetrates the upper base material and expands at the tip due to the shape of the die within the lower base material. 2. In the context of the need to reduce CO2 emissions, the fastening method RIVCLINCH, which uses only air as a power source, does not generate heat and does not require auxiliary materials like rivets. By applying multiple points, it can achieve equivalent strength compared to spot welding and SPR in shear strength comparisons. 3. 'RIVTAC' can fasten high-strength materials at high speed without the need for a pre-drilled hole. It can be used for profile structures with access from one side, and it is also possible to fasten dissimilar materials or use adhesives in conjunction.
