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, 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)

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.

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.

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

The details of the product we are introducing this time are as follows: JIS (Plating) Type: 90E(S) Material: PY400 Size: 1500A (60 inches) Thickness: 7.9mm This is a plated product of a 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 the material 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.
