Rotary joint

Ultra-high pressure 200 MPa rotary joint

This is a super high-pressure swivel joint with a maximum operating pressure of 200 MPa. There are two types: the PF type, which can rotate 360° under pressure, and the PL type, which does not rotate when pressurized. Its compact design allows for use similar to standard fittings, contributing to reduced workload in high-pressure cleaning and lowering the risk of hose kinking.

Please let us know if you have any issues with non-standard, special, or unique specifications!

Benkan Kiko will take on your troubles and "wish list" regarding welded pipe fittings!

At Benkan Kiko, based on our expertise in manufacturing welded pipe fittings, which includes "plastic processing," "welding," "machining," and "handling various materials," we value feedback from our customers and strive to develop new products according to their requests. We are committed to collaborating with our customers to explore ideas that may not be found anywhere else, asking, "Can you make something like this?" 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 fitting guide for piping - Bar and sleeve T (tee)

Introducing the guide bar sleeve T-shirt.

In the field of plants where piping is installed, welding of pipe fittings to pipes and welding of pipe fittings to pipe fittings must often 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 pipe 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 parts of sleeves and guide bars, so please feel free to contact us first.

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, enabling space-saving designs. In the case of stainless steel, the weight of the piping can be reduced by about 70% compared to carbon steel, making its strength and space-saving benefits easy to understand. This also brings advantages in reducing on-site labor costs. Benkan Kiko's pipe fittings (Su fittings) are approved for use under fire protection laws and have obtained JIS certification (JIS B 2309). The trusted brand Benkan Kiko, which is 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 ordinance revising part of the "Ordinance on Water Quality Standards" was promulgated, which revised the amount of hexavalent chromium compounds. Our company has conducted leaching performance tests under the new standards, and 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 skills!

It is a joint that makes you think it could be a sculpture, finished to a stunning degree. This is made by "cutting out," which means it is created by machining from forged material, not through 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 pulling steel materials). For such requests, we manufacture by cutting from forged materials rather than using conventional plastic processing. The shapes mainly include Y-PIECE, which branches at the same angle from one direction; LATERAL, which branches at an angle like a branch from one direction; and T-PIECE, which branches 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. Not only do the shapes need to fit, but we also conduct UT tests on the materials, tensile tests, impact tests, hardness tests, and penetration tests on the products, and we provide the final products only after all tests are cleared.

Welded pipe fittings for piping [non-ferrous metals]

Benkan Kiko also manufactures welded pipe fittings made from non-ferrous metals.

"Non-ferrous metals" refer to metals that are different from "carbon steel," "alloy steel," and "stainless steel," and include types such as "aluminum alloys" and "nickel alloys." Benkan Kiko manufactures welded pipe fittings made from "non-ferrous metals," which are difficult to control in shaping, utilizing the metal plastic processing technology cultivated over many years, and has a wealth of delivery achievements. Additionally, by leveraging various material procurement sources developed over time, we have established a system that can support customers' piping designs by accommodating a wide variety of steel types. We can also handle many other materials, including "Inconel," "Hastelloy," and "Monel," so please contact us for more details. We also introduce "non-ferrous metals" on the Benkan Kiko blog, so please take a look.

Welded pipe fittings with hot-dip galvanized coating

Due to cutting processing, the step of removing the zinc plating adhered to the bevel area is unnecessary!

The product we are introducing this time is the NBG joint, which has undergone cutting processing on its zinc plating. When performing the peeling work of the zinc plating attached to the groove section, leaving any residue and then proceeding with welding can lead to the generation of harmful substances due to the heat effects during welding. Therefore, there is a concern about the generation of harmful substances, and the peeling work creates a burden and hassle on-site. The NBG joint is a welded pipe joint from which the zinc plating attached to the groove section has already been removed through cutting processing. As a result, it eliminates the need for the peeling work process before performing the surrounding welding, alleviating concerns during the welding process and improving work efficiency. The NBG joint is primarily used in air conditioning equipment that creates a comfortable living environment and is active in various fields such as large building facilities and commercial establishments. Please consider the NBG joint, which can eliminate the peeling process and reduce concerns about harmful substance generation as well as the burden and hassle of peeling work. NBG stands for "Non Bevel Galvanized," a unique expression of Benkan Kiko.
