Welded pipe fittings clad steel Benkan Kiko

We manufacture welded pipe fittings from clad steel plates made by bonding two types of materials to meet your requirements.

Large-diameter welded pipe fittings are typically manufactured from carbon steel plates, alloy steel plates, and stainless steel plates, each from their respective materials. What we would like to introduce this time is a T (tee) welded pipe fitting made from a plate that has a thin steel plate of UNS8825 bonded to WPHY60 steel plate on the inside. In addition to general carbon steel and stainless steel, it is possible to manufacture from a variety of materials, including low alloy steel, high alloy steel, duplex stainless steel, super stainless steel, aluminum, nickel, and high-strength steel. Among these diverse materials, it is also possible to manufacture from clad steel plates, which combine two types of materials. Furthermore, production is also possible from seamless materials or overlay materials that are not steel plates.

[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 held detailed discussions to propose products that our company could provide. As a result, our extensive delivery track record to power plants, along with our quality and inspection system, as well as our ability to create documentation, were highly evaluated, 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, and thickness 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 locations.

Non-ferrous metal aluminum pipe fittings

Benkan Kiko also manufactures aluminum pipe fittings.

At Benkan Kiko, we have a wealth of experience in the manufacturing of aluminum and aluminum alloy pipe fittings. Characteristics of Aluminum: - It is lightweight and easy to process, but has low strength. - It has good thermal conductivity. - Its toughness does not decrease at low temperatures, making it suitable for use in extremely low temperatures such as liquid hydrogen at -252.7°C. - It has excellent weather resistance due to the formation of an oxide film when it reacts with oxygen in the atmosphere; however, this oxide film can be destroyed in acidic or alkaline environments, particularly in the presence of chloride ions or alkaline conditions. Due to these characteristics, aluminum is a material that is difficult to shape and weld. However, it offers significant advantages such as corrosion resistance and maintaining toughness at low temperatures, making it suitable for piping in harsh corrosive environments like seawater, as well as for extremely low-temperature piping and tanks for liquefied natural gas and liquid hydrogen. At Benkan Kiko, we have established molding and welding techniques through years of accumulated technology and know-how, enabling us to manufacture with delicate materials like aluminum. Additionally, based on our extensive experience and achievements, we can flexibly address various problem-solving needs. Please feel free to consult or request our services with confidence.

Welded pipe fittings with PAD (backing plate)

If you want to attach a PAD (backing plate) to a pipe fitting, please consult Benkan Kiko!

"I want to join the pipe fittings and support materials, but I'm concerned about strength and thermal effects, so I don't want to attach them to the main body of the pipe fitting. Welding and attaching a PAD (backing plate) to the pipe fitting on-site is cumbersome." In such cases, please do not hesitate to contact Benkan Kiko. By attaching a PAD (backing plate) to the necessary parts in piping support structures (horizontal and vertical loads), we can enable the joining of the PAD section and the support material. However, manufacturing pipe fittings with PADs is not easy. The PAD and the pipe fitting are produced separately through plastic processing, but welding them together so that they fit perfectly requires a very difficult task known as PAD shape correction. Benkan Kiko has three domestic factories (five locations) and various know-how accumulated by skilled craftsmen who hone their skills there. There have been cases where pipe fittings with PADs, which were deemed technically difficult during the consideration stage, were made possible by pooling wisdom and technology across factories. Although the PAD (backing plate) attached welded pipe fittings are custom-made and unique, please consider contacting Benkan Kiko when you are evaluating your options.

Welded pipe fittings finished with buffing polish.

For welded pipe fittings with buff finish polishing, please consult Benkan Kiko.

There are cases where "polishing" is required for the surface finish specifications of welded pipe fittings, and particularly for stainless steel products, a glossy and smooth finish is achieved through "buff polishing." "Buff polishing" is a method that uses a polishing tool equipped with cotton, felt, or wool called a "buff," along with a paste-like polishing material, to smooth the surface, especially when a mirror finish is required. Buff polishing has classifications of "roughness," expressed as a certain grade number. Generally, the larger the number, the higher the grade, resulting in a glossier surface on the product. At Benkan Kiko, regardless of buff polishing finish, we accommodate surface grade specifications not only with the polishing material grade but also with surface roughness parameters (Ra, Rmax, etc.), roughness symbols, evaluations using comparison test pieces, and evaluations using surface roughness gauges, allowing us to meet surface grade requirements tailored to specific applications. If polishing is necessary for welded pipe fittings in piping design, please feel free to contact us. <Varieties> - Elbows, T, reducers, caps, stub ends <Materials> - We can accommodate various materials including SUS304, SUS304L, SUS316, SUS316L, and others.

Low-pressure bellows-type expansion joint "Hinged single type HS / double type HD"

The pressure is 0.2MPa to 0.8MPa! A bellows-type expansion joint that can also be combined with a gimbal type.

The "Hinged Type Single HS/Dual HD" is a bellows-type expansion joint that can absorb large displacements caused by earthquakes and other factors through its combination. The hinged type restrains internal pressure thrust with a hinge arm attached to the side of the bellows and a central pin, allowing it to bend the bellows around the pin to absorb angular displacement. By combining two or three hinged types, it can absorb larger displacements than a universal type. 【Features】 ■ Capable of absorbing large displacements from earthquakes and other factors through combinations ■ Absorbs angular displacement by bending the bellows around the pin ■ By extending the intermediate pipe, larger lateral displacement Y can be achieved ■ Can be combined with gimbal types ■ Pressure: 0.2MPa to 0.8MPa *For more details, please refer to the PDF document or feel free to contact us.
