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

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

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

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.

Welded pipe fittings for piping [non-ferrous metals]

Welded pipe fittings for piping [non-ferrous metals]

At Benkan Kiko, we also manufacture 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," including types such as "aluminum alloys" and "nickel alloys." At Benkan Kiko, we manufacture welded pipe fittings using "non-ferrous metals," which are difficult to control in shaping, thanks to our long-established metal plastic processing technology, and we have a wealth of delivery achievements. Additionally, by utilizing various material purchasing sources we have developed over the years, we are equipped to support our 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

Welded pipe fittings with hot-dip galvanized coating

Due to cutting processing, the process of removing the zinc plating adhered to the bevel section is unnecessary!

The product we would like to introduce this time is the NBG joint, which has undergone cutting processing with zinc plating. When performing the peeling work of the zinc plating attached to the bevel area, conducting welding while leaving some plating can lead to the generation of harmful substances due to the thermal 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 bevel area has already been removed through cutting processing. As a result, it eliminates the process of peeling the plating before performing the surrounding welding work, removes concerns during the surrounding welding, and improves work efficiency. The NBG joint is mainly 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," which is a unique expression of Benkan Kiko.

General piping stainless steel welded pipe fittings - Benkan Kiko

General piping stainless steel welded pipe fittings - Benkan Kiko

With Su pipe fittings, it is possible to reduce the weight and cost of piping.

Su (Esu Yuu) pipe fittings are thin-walled stainless steel butt-welded pipe fittings (JIS B 2309) that have been reduced in thickness to a level suitable for general piping stainless steel pipes (JIS G 3448 TPD). This thinning has achieved a reduction in the weight of the piping and a decrease in costs, which has led to a reduction in on-site construction burdens and has received positive feedback. The material used is often [SUS304WD] since it is for general piping, but in special environments such as buried corrosion resistance, [SUS316WD] may be used. Our company can accommodate both options. The maximum specification pressure is 2.0 MPa.

Large-diameter welded pipe fittings - branch pipes

Large-diameter welded pipe fittings - branch pipes

Benkan Kiko's large-diameter lateral pipes reduce on-site welding work!

The photo shows a lateral pipe where the branch pipe is connected diagonally to the main pipe. The connection of the branch pipe requires saddle welding on a curved surface, and since the branch pipe is connected at an angle rather than at a right angle, the connection surface becomes elliptical, which demands a very high level of skill from the welder. Additionally, a backing plate (pad) is welded to the main pipe using fillet welding. The backing plate is applied to reinforce the piping branch, and when performing prefabrication or on-site piping, there are concerns that directly welding support materials or foot materials to the product may affect the quality of the main pipe and the qualifications of the welders performing that welding. Therefore, the backing plate is used to address such concerns. The manufacturing of this backing plate also requires high forming skills to match the curved shape of the main pipe, but Benkan Kiko is capable of handling this. At Benkan Kiko, we can supply high-quality products through excellent welding technology and precise forming techniques.
