General piping stainless steel welded pipe fittings - Benkan Kiko

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

Su (Syu) 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 allows for lighter piping and cost reduction, leading to a decrease in on-site construction burdens, which 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

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 skill level 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.

T-shirt with guide bar

It is something that is indispensable for gas pipelines.

The pipeline has not only straight sections but also bends and branching parts. The guide plate that allows the pig to pass smoothly through the branching section without getting caught on the branch side is called a guide bar (pig bar). At Benkan Kiko, we manufacture elbows used in the bending parts of pipelines and T (tee) fittings used in branching parts, but the T fitting with a bar attached to the branching part is referred to as a T fitting with a guide bar. Regarding the guide bar, there are various know-how related to its shape and installation method, and welding to the T fitting body often needs to be performed using a welding method (welding construction method) approved based on regulations such as the Gas Business Act. 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. In addition to being able to accommodate various shapes of guide bar installations according to customer requests, we can also procure the materials for the guide bars ourselves. Furthermore, we are qualified to conduct various tests and inspections on the welding parts of the guide bars. Source of pig photo: JFE Engineering Corporation.

There are such differences between the PT370 and PG370 pipe fittings.

Among the welded pipe fittings manufactured by Benkan Kiko, the ones with material codes "PG370" and "PT370" are particularly produced in large quantities. We receive many inquiries from customers regarding the differences between "PG370" and "PT370." Pipe fitting "PG370" ... is a pipe fitting for pressure piping. - It connects to the steel pipe STPG370 according to JIS G 3454. - It is mainly used for pressure piping at temperatures below approximately 350°C (excluding high-temperature applications). - The maximum operating pressure is typically below 10MPa. Pipe fitting "PT370" ... is a pipe fitting for high-temperature piping. - It connects to the steel pipe STPT370 according to JIS G 3456. - It is mainly used for high-temperature piping at temperatures exceeding 350°C (up to approximately 450°C). - The maximum operating pressure is typically below 20MPa. These are the differences.

The "ES Free-Form Single" is a bellows-type expansion joint that absorbs axial thermal displacement of low-pressure piping and vibrations from low-pressure pump blowers. Ground subsidence can cause misalignment, and vibrations from pumps or compressors can transmit through the piping, potentially causing unexpected issues with equipment or buildings. In such cases, this product demonstrates excellent effectiveness. 【Features】 ■ Simple shape in the basic form ■ Absorbs axial thermal displacement of low-pressure piping and vibrations from low-pressure pump blowers ■ Pipes expand and contract due to changes in fluid temperature or ambient temperature *For more details, please refer to the PDF document or feel free to contact us.
