For special angles (end angles) elbows, please leave it to Benkan Kiko.
A non-standard angle elbow refers to elbows with intermediate angles other than the typical 90° or 45°. In piping design, by manufacturing special intermediate angle elbows such as 85.5° or 37° or 135°, it becomes possible to install and connect piping in spaces that cannot accommodate standard elbows. We can manufacture elbows at the angles requested by our customers and also offer product suggestions to address any challenges you may have. Please feel free to consult with us.
Leave special specification pipe fittings to Benkan Kiko.
The product we are introducing this time is an elbow with a rectifying plate. A rectifying plate is a plate that is installed on the inside of pipe fittings such as elbows, and it serves to streamline the flow of fluid passing through the piping. When welding the rectifying plate, it is necessary to consider the bending radius (angle) of both the elbow and the welding plate, which requires a high level of skill. At Benkan Kiko, we have received high praise from our customers by being able to accommodate special products thanks to our high technical capabilities cultivated over many years. We can manufacture in various materials and sizes, so please feel free to contact us first.

![[Case Study] Power Plant Elbow Piping Replacement Work](https://image.www.ipros.com/public/product/image/211/2000470078/IPROS10386970725550407701.jpeg?w=280&h=280)
We would like to introduce an example of on-site piping replacement work that reduces management burdens!
We received an order for products for the replacement work of elbows with long seam welds, which we supplied several decades ago, for the after-service project at the Nagasaki Plant of Mitsubishi Heavy Industries, Ltd. for their thermal power plant. This project involved the on-site replacement of aging piping used under high temperature and high pressure conditions. However, instead of supplying the same elbows as before, we provided a new product that incorporates many advantages, which was well received. The specifications of the product that were appreciated are as follows: - Seamless elbows to eliminate long seam welds. - To reduce the workload within the engineering manufacturer, a hydraulic pressure test was conducted at Benkan Kiko at a pressure of 1.3 times the design pressure. - To facilitate easy replacement work on-site, lifting fixtures were installed. By conducting the hydraulic pressure test at 1.3 times the design pressure in advance at Benkan Kiko, we can avoid the risk of performing a hydraulic pressure test at 1.3 times the design pressure on aging piping. We have confirmed and experienced effects such as delivery management and workload reduction, and we have received high evaluations, including subsequent orders for after-service projects under the same scheme.
Introducing the large-diameter monaka-style elbow with an outer diameter exceeding 2 meters!! This 80-inch (outer diameter 2032mm) large-diameter elbow is available. Leave the manufacturing of large-diameter elbows to Benkan Kiko.
The name "Monaka" originates from a type of Japanese confectionery called "monaka," which consists of two wafers filled with sweet bean paste. 1. Enhanced facilities enable the production of products tailored to your needs When manufacturing large-diameter elbows, a method may be employed that combines steel pipes known as "maita bends" and "ebi pipes" to create elbow shapes. The Monaka manufacturing process requires molds and high-output pressing machines. Our facilities are well-equipped, allowing us to produce products that meet our customers' requirements. 2. Fewer weld seams reduce the risk of welding defects Due to the manufacturing method of combining steel pipes through welding, maita bends tend to have many weld seams, resulting in increased inspections. Our elbows have only two weld seams along the length, significantly fewer than maita bends, thereby reducing the need for inspections on weld seams and minimizing the quality risks associated with welded joints, allowing for safer usage. 3. Smooth shape minimizes the impact on fluids Maita bends have an angular shape due to the combination of steel pipes, while our formed elbows have a smooth R shape, which minimizes the impact on fluids. We can accommodate various materials (for details, please refer to the section below), so please feel free to contact us.
Connection between PVC pipes and steel pipes is possible 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 fitting that does not require disassembly and can be installed using a short wrench. It is ideal for connecting to existing pipes during renovations in apartments and similar settings. When connecting PVC pipes, no adhesive is used, so there is no need for drying or curing, allowing for immediate water flow after connection. When connecting steel pipes, there is no need for threading the pipes, enabling immediate installation after cutting the pipes. With low tightening torque, it can be installed using short tools like a short wrench, which reduces installation time and allows for work in tight spaces. There is also a rich lineup of fittings available, including diameter-reducing sockets, elbows, tees, male-threaded sockets, and female-threaded sockets.

We will weld a plate to the HT elbow (PVC water pipe) to create a waterproof plate. Due to the characteristics of the material, we will strive to meet your requests regarding tolerances and distortions as closely as possible.
At Takimoto Giken Kogyo, we manufacture waterproof plates by welding plates onto HT elbows (PVC water pipes). While it is a heat-resistant grade, the plates themselves are of standard grade. Materials for the construction industry often require additional processing of PVC water pipe standards, and instructions may vary depending on the site. PVC (polyvinyl chloride) has high chemical resistance but low heat resistance; however, it is inexpensive as a material and can be both glued and welded, making it widely used for safety covers and processed building pipe materials. Using a welding machine (Fuji Impulse), we weld materials such as PVC (polyvinyl chloride), PP (polypropylene), and PE (polyethylene) by applying heat and melting the welding rod. We can produce even "small lots," starting from just one piece. We can also accommodate repeat orders from single items. While we can accept mass-produced items (those with large quantities) that result in a higher total amount, we also handle small lots (those with fewer quantities) that are often difficult to accept elsewhere. In recent years, user requests have diversified, and we are committed to making efforts to meet these demands, so we appreciate your guidance and support. *For more details, please refer to the PDF materials or feel free to contact us.*

It is possible to reduce transportation and construction costs through compactification!
The 3DR elbow is a type of pipe fitting that is commonly used in gas pipelines. It is often manufactured using high-frequency bending, but due to the manufacturing process, an extra length of 1OD (1 outer diameter) is required as a gripping area. However, having this extra length makes it cumbersome during transportation. Additionally, in the case of underground installation, the extra length necessitates deeper excavation during construction, which increases labor costs, including handling. Since many products are used for mainline applications, the impact on costs is considered significant. However, if manufactured using the mandrel method, the absence of extra length improves loading efficiency onto trucks and eliminates the need for deeper excavation during underground installation of the pipeline, making construction easier. Furthermore, the wall thickness of the bend is almost uniform, and the entire elbow undergoes heat treatment, resulting in consistent mechanical properties and high quality, with no discontinuities in wall thickness, making it safe for use in high-pressure conduit mainlines. At Benkan Kiko, we offer 3DR elbows manufactured using the mandrel bending method. We can provide cost-benefit calculations, so please feel free to consult with us.
