Creating a safe environment for workers

Over the last fifteen years, the innovative Just Flare Piping System from Nissyo Techno Co., Ltd. has made a major change in the construction industry. The groundbreaking device has improved efficiency in the piping process, an essential element in construction.

In most situations, pipe-welding is performed by professional welders using heat, gas and/or electricity. Not only does this process require a tremendous amount of labor, time and skill, but it also puts the worker at risk, as harmful zinc fumes are produced in the welding process. Despite this difficult situation, a large team and a tight construction schedule is generally required.

Established 48 years ago, Nissyo Techno once had their own team of welders, but they felt an urgent need to change the working environment that posed health hazards to their employees. Seeking an alternative to the conventional system, they bought and installed a flanging machine, a five-ton device-the only kind available in the market at that time. Though it helped the situation, the bulky size and weight as well as complex operation of the device caused inefficiency. One way to solve this problem was to create a flanging machine of their own, which led to the development of the Just Flare JF-350, a light, compact device that weighs only 1.5 tons. Without welding or heat, the machine flare-forms the pipe end into a flange, resulting in a lap-joint shape. These pipes are then joined easily and securely by loose flanges with a gasket in between. Thus, a safer working environment is created while increasing productivity exponentially.

A productive and ecological solution

The Just Flare JF-350 is a perfected flanging machine. The compact body can be transported on a two-ton truck, making it possible for use on-site at all times. It performs well with larger pipes, which can be the most burdensome for welders. Making only minimal noise, within a minute and 20 seconds, the pipe end is formed into a flange to create a reliable connection.

The machine can produce what a person would in one-fifteenth of the time, and since it involves no heat or flame, it eliminates the danger of zinc fumes and accidents commonly associated with the process if done manually. The high quality performance is constant, which also eliminates such risks as leakages from poor welding jobs or corrosion on welded joints. The goal of improving the working conditions for company workers has not only led to a reduction in health risks but also time and costs to a large degree. The new technology has had environmental benefits as well, due to significantly less electricity use and resultant carbon dioxide emissions.

Flanging machines of the future

The strength and durability of the Just Flare JF-350 piping system is supported by a long track record of major construction projects throughout the country, from manufacturing plants to public establishments. Fukushima Prefecture, where the company is based, suffered severe damage from the 2011 Tohoku Earthquake. Nevertheless, it was reported that the piping systems installed in the region with the Just Flare, except for those that completely collapsed, showed no signs of leakages.

The Just Flare innovation is changing the working environment for people in Japan and around the world. An additional version of the Just Flare system is being developed, to be presented in 2014.
