Non-ferrous metal aluminum pipe fittings

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, making it particularly vulnerable to chloride ions and 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 maintained 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 shaping and welding technologies through years of accumulated expertise and know-how, enabling us to manufacture with delicate materials like aluminum. Additionally, based on our extensive experience and numerous 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)

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 worried about strength and heat effects, so I don't want to attach them directly to the pipe fitting body. 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 pipe fitting are produced separately through plastic processing, but welding them together so that they fit perfectly requires the very challenging task of modifying the PAD shape. 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 we made it possible to manufacture PAD-equipped pipe fittings, which were considered technically difficult during the planning stage, by pooling wisdom and technology across factories. Although the PAD (backing plate) equipped welded pipe fittings are custom-made and unique, please contact Benkan Kiko when considering them.

Welded pipe fittings finished with buff polishing.

Welded pipe fittings finished with buff polishing.

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

There are cases where "polishing" is applied as a surface finish specification requirement for welded pipe fittings, and particularly for stainless steel products, there is a smooth, glossy finish 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 abrasive material, to smooth the surface, especially when a mirror finish is required. Buff polishing has classifications of "roughness," expressed as a specific number finish. Generally, the larger the number, the higher the grade, resulting in a glossier product surface. At Benkan Kiko, regardless of buff polishing finish, we accommodate surface grade specifications not only with abrasive particle sizes but also with surface roughness parameters (Ra, Rmax, etc.), roughness symbols, evaluations using comparison test pieces, and assessments using surface roughness gauges, allowing us to meet surface grade requirements tailored to specific applications. If polishing is required for welded pipe fittings in your piping design, please feel free to contact us. <Varieties> - Elbows, T-pieces, reducers, caps, stub ends <Materials> - We can accommodate various materials including SUS304, SUS304L, SUS316, SUS316L, and others.

[Case Study] Large-Diameter Plated Products for Air Conditioning Equipment Piping in Architecture

[Case Study] Large-Diameter Plated Products for Air Conditioning Equipment Piping in Architecture

As a manufacturing example, we would like to introduce large-diameter plated products (hot-dip galvanized) produced for air conditioning equipment piping.

The details of the product we are introducing this time are as follows: JIS (Coating) Type: 90E(S) Material: PY400 Size: 1500A (60 inches) Thickness: 7.9mm This is a coated large-diameter welded pipe fitting as specified by the customer. In particular, processing of hot-dip galvanized products such as 1500A (60 inches) is not easy and is a high-difficulty product. Benkan Kiko also manufactures large-diameter products. 《Manufacturing Range》 Size: up to 2000A (80 inches) Thickness: up to 120mm *Please note that this varies by type, so for details, please contact us. Pipe fittings made from steel pipes as raw materials can be difficult to obtain depending on the size, making them unsuitable for manufacturing large-diameter products. The production of large-diameter pipe fittings can be achieved by forming and welding from steel plates.
