ベンカン Company Overview

Mission: To propose the construction of a reliable lifeline through the development and supply of piping that considers not only the present but also the future.

Since our establishment in 1947 as a manufacturer of welded pipe fittings, we have been involved in piping. Currently, we are advancing our business focused on sustainable piping, with a mission that aligns with the SDGs (Sustainable Development Goals) adopted at the United Nations Summit in 2015. (Mission brand: SUSTAINABLE LIFELINE) Specifically, our business model primarily involves proposing stainless steel piping. Our headquarters and MJ factory are located in Ota City, Gunma Prefecture. We have six sales offices in Sapporo, Sendai, Tokyo, Nagoya, Osaka, and Fukuoka. Additionally, we have a manufacturing base overseas in Benkan Vietnam (100% investment). Together with over 400 employees, we aim to be a company worthy of being called "Benkan of Stainless Steel Piping."

Business Activities

Stainless steel piping is a representative of sustainable piping that excels in durability, hygiene, and toughness. However, traditionally, it required a high level of technical or equipment expertise, resulting in high costs, which prevented its widespread use in general piping. The mechanical joints proposed by Benkan have lowered the level of expertise required for installation and achieved cost reductions, leading to its adoption in general piping. Nowadays, it is widely used not only in facilities where sustainability is particularly required, such as hospitals, police stations, fire stations, government buildings, welfare facilities, and schools, but also in a variety of buildings including hotels, commercial spaces, intelligent buildings, condominiums, and single-family homes for water supply, hot water supply, and air conditioning piping. Furthermore, we are also working on the development of aluminum piping as a new material for the future, not just limited to stainless steel piping.
