KURO Fitting

KURO Fitting

This is a plug-in welded joint developed for small diameter sizes. By minimizing the tolerance with the tube and creating a WELD LINE that allows anyone to easily and reliably perform welding, it enables the construction of a leak-free (after passing leak tests) and clean piping system using TIG to weld the WELD LINE without the need for welding rods. It is particularly suitable for high-purity piping for toxic, flammable, semiconductor gases, vacuum, fuel cells, and scientific instruments, where tightening methods may not provide sufficient safety. It is undoubtedly helpful in reducing piping time. Product shapes: elbow, tee, cross, sleeve, cap, reducer sleeve, reducer tee, reducer elbow, etc. Dimensions: 3.18 mm to 25.4 mm Minimum order quantity: from 1 piece *We ship anywhere in the country! (We also ship overseas)

Please let us know your concerns regarding non-standard, special, or unique specifications!

Benkan Kiko will take on your troubles and wishes regarding welded pipe fittings!

At Benkan Kiko, based on our expertise in manufacturing welded pipe fittings, including "plastic processing," "welding," "machining," and "handling various materials," we value your feedback and strive to develop new products according to customer requests. We think together with our customers about ideas that are not found anywhere else, asking, "Can you make something like this?" and bring them to life. For example... - We would like you to weld a steel pipe (single pipe) to an elbow and deliver it. - A T (tee) with a complex shape, and we are unsure if it can be manufactured. - We don't know which manufacturer to ask. *In the "Applications/Examples of Achievements" section below, we introduce some of the products we have manufactured so far!

Welded pipe fittings for plants - PT test

For the quality of welded pipe fittings (welded joints), trust Benkan Kiko.

The photo shows the PT test (penetrant testing) being conducted on welded pipe fittings. Penetrant testing is a type of non-destructive testing that is performed without causing physical damage to the product or test piece, and it is used to detect defects that are difficult to see visually on the surface of the product. (This testing method only targets the detection of surface-open defects.) *The coloration in the photo below (detailed information section) is a sample.

Welded pipe fittings guide for piping - Bar and sleeve T (tee)

Introducing the guide bar sleeve T-shirt.

At the construction site of a plant where piping is installed, welding of pipe fittings to pipes and welding of pipe fittings to pipe fittings often must be carried out using approved welding methods (welding construction methods) based on regulations such as the Gas Business Act. Since there are many types of welding construction methods depending on the material of the pipes and the welding method, it is not always possible to accommodate all sites. Therefore, by pre-welding short pipes at Benkan Kiko, it becomes possible to align with the welding construction methods that can be used on-site. Benkan Kiko has obtained many welding construction methods based on regulatory requirements such as the Gas Business Act and the Electric Utility Act, allowing us to respond to various cases. Additionally, we can accommodate various shapes for guide bar installation according to customer requests, and we also offer the option to purchase materials for guide bars and sleeves from our company. We are qualified to conduct various tests and inspections on the welded joints of sleeves and guide bars, so please feel free to contact us.

Firefighting piping fittings (Su fittings) Benkan Kiko

Using stainless steel piping for fire protection systems offers many advantages!

Are you thinking, 'It's impossible because stainless steel piping is too expensive'? By using stainless steel for fire protection piping, you can extend the lifespan of the piping system due to the corrosion resistance characteristic of stainless steel compared to carbon steel. Additionally, the strength of stainless steel allows for thinner piping, making it possible to save space. In the case of stainless steel, the weight of the piping can be reduced to about 70% of that of carbon steel, so you can easily understand its strength and space-saving benefits. This also leads to reduced labor costs on-site. Benkan Kiko's pipe fittings (Su fittings) are approved for use under the Fire Service Act and have obtained JIS standard certification (JIS B 2309). The trusted brand Benkan Kiko's Su fittings, used not only for fire protection systems but also for general piping stainless steel, will assist you in converting fire protection piping to stainless steel. In March 2020, the amount of hexavalent chromium compounds was revised in the "Ordinance to Partially Amend the Ordinance on Water Quality Standards," and our company has conducted leaching performance tests under the new standards, ensuring that our Su fittings meet the revised water quality standards.

Forged steel fittings for thermal power plants

We can respond to the special shapes of welded pipe fittings used in boiler applications with high technical skill!

It is a joint that makes one think of a sculpture, finished to an impressive degree. This is made by "machining," which involves cutting from forged material rather than plastic processing. Among the welded pipe joints used in boiler-related applications at thermal power plants, there are products with large and special shapes that cannot be made through plastic processing (stretching, compressing, bending, or drawing steel materials). For such requests, we manufacture by cutting from forged material instead of using standard plastic processing. In terms of shape, there are mainly Y-PIECES that branch at the same angle from one direction, laterals that branch at an angle like a single branch from one direction, and T-PIECES that branch in a T shape. The diameters primarily range from 400 to 800 mm, with some larger ones weighing around 10 tons. Since these products are used under extremely harsh conditions, the specifications include strict component regulations for the materials used and heat treatment conditions based on the technical standards for power generation thermal equipment. We not only ensure that the shape is correct but also conduct UT tests on the materials, tensile tests on the products, impact tests, hardness tests, and penetration tests, and only provide the final product after all these tests are cleared.
