Proposal for Prefabricated Piping for Nuclear Power.

Proposal for Prefabricated Piping for Nuclear Power.

Benkan Kiko provides piping materials that meet the requirements of nuclear power management.

Benkan Kiko has a wealth of delivery experience in welded pipe fittings for all nuclear power plants in Japan. Utilizing our expertise in stringent quality control for nuclear applications, as well as the management of documentation and quality records, and the technology for long and circumferential welds on items subject to inspection by welding contractors, we manufacture not only items subject to such inspections but also prefabricated piping that requires nuclear management, which has a significant track record for the necessary remedial work for the recent restart of nuclear power plants. In particular, we produce and deliver prefabricated piping that combines fittings, flanges, nozzles, and nipples for fire protection piping, which traditionally does not require nuclear management, and we also conduct strength calculations for these flanges, nozzles, and nipples based on JSME (Japan Society of Mechanical Engineers) standards. We can manufacture using both stainless steel and carbon steel (galvanized), and we also respond to various other requests.

Welded pipe fittings made from clad steel

Welded pipe fittings made from clad steel

Clad steel generates benefits in various cases, such as reducing overall piping costs and accommodating materials that can only be purchased in rare materials or thin plates.

Clad steel refers to a composite material that uses carbon steel, high-strength steel, low-alloy steel, etc., as the base material, and combines it with a different type of steel on one side through processes such as hot rolling (bonding), welding, or explosive bonding. By enabling the joining of dissimilar metals, it can create functions that cannot be achieved with a single type of metal. By combining materials with good corrosion resistance or by using less expensive metals in combination with more expensive ones, it is also possible to reduce the overall cost of piping. This type of steel offers advantages in various cases, such as accommodating rare materials or materials that can only be purchased in thin sheets. *The photo shows a cross-section of clad steel, where the combination of dissimilar metals can be seen.

Special Item: Welded Pipe Fitting "Cross"

Special Item: Welded Pipe Fitting "Cross"

Instead of machining, we can reduce costs by manufacturing from seamless pipes!

In the variety of welded pipe fittings, elbows, Ts, and reducers are common, but fittings that have branches on the top and bottom resembling a T are referred to as crosses due to their cross-shaped design. This type of pipe fitting is not specified in JIS standards and is mostly manufactured by machining from forged materials. However, Benkan Kiko is capable of producing them using the bulging method (hydraulic forming) from seamless pipes. The machining method tends to result in heavier weights and often produces angular shapes, which can make welding at construction sites difficult. Additionally, the method of machining from a solid block requires a significant amount of material, leading to higher material costs and increased processing costs. Manufacturing through shaping from seamless pipes allows for smooth shapes, uniform wall thickness, and lighter product weights, while also achieving cost reductions. This cost advantage becomes more pronounced with high-cost materials such as stainless steel and non-ferrous metals like nickel, resulting in significant benefits. For more details, please feel free to consult our sales office.

Benkan Kiko Special Coating Pipe Fittings

Benkan Kiko Special Coating Pipe Fittings

Special coating application for pipe fittings is available according to customer requests.

Steel products are easily corroded when left uncoated in the atmosphere, and rust occurs electrochemically due to oxygen and moisture in the air. It is possible to protect the products from corrosion and aging conditions by applying paint. Steel products used in plants and pipelines are particularly often painted, and at Benkan Kiko, we can supply products that have been painted or coated with customer-specified paints, thereby reducing the need for on-site painting work. For products that do not have special painting instructions, we apply temporary rust prevention that suppresses rust for about six months during indoor storage.

[Case Study] Welded Pipe Fittings Made of Stainless Steel for General Piping in Hydroelectric Power Plants

[Case Study] Welded Pipe Fittings Made of Stainless Steel for General Piping in Hydroelectric Power Plants

You have adopted welded pipe fittings made of stainless steel with excellent corrosion resistance.

The river water around the Yonago River No. 1 Power Plant in Suzaka City, Nagano Prefecture, has a strong acidity with a pH of 3.23, making it unsuitable for agricultural use and as a habitat for fish. However, in order to effectively utilize resources and contribute to the community while ensuring environmental conservation through profit return, the establishment of a hydroelectric power plant was initiated. In this context, we were approached through the Ipros site, and we had the opportunity to visit the site. We had detailed discussions to propose products that our company could assist with. As a result, we were evaluated positively for our extensive delivery track record to power plants, quality and inspection systems, and our ability to create documentation, leading to our adoption. The welded pipe fittings we supplied this time are made of stainless steel, model 90-45EL, material SUS304W, sizes 600A and 400A, with a thickness of S10S. We believe that stainless steel, which is highly resistant to corrosion, is essential for the river water with strong acidity used in hydroelectric power plants. In this way, Benkan Kiko's welded pipe fittings are used in various places.
