About Utsunomiya Propane cylinder Inspection Factory Co., Ltd.

Utsunomiya Propane cylinder Inspection Factory Co., Ltd. (hereinafter referred to as Utsunomiya Propane Co., Ltd.) was founded 61 years ago as of 2024.
The company's main business is the reinspection of LP gas cylinder, and it is currently providing reinspection and delivery services for LP gas cylinder over a wide area, from Fukushima Prefecture in the north to Kanagawa Prefecture in the south, mainly in the Kanto region. It has also started new businesses, such as the disposal of cylinder valves and the scrapping of bulk storage tanks. The company alsoactively accepts foreign technical intern trainees, and has had 5-6 trainees employed at the company for the past 5 years.

This time, our equipment was selected when the pressure test equipment was updated.

Update contents: Two fully automatic non-tank pressure test equipment (DNS-850), a simple non-tank pressure test equipment (DNJ-220F), and an oil/water vapor recovery tower.
Update date: July 2023

What prompted the update?

Utsunomiya Propane Co., Ltd. not only values meeting delivery deadlines, but also delivering high-quality cylinder that are free of scratches and stains to their customers. They said that delays in operations due to breakdowns and troubleshooting of existing equipment from other manufacturers were hindering the company's philosophy, which was what prompted them to consider updating. Utsunomiya Propane Co., Ltd. also cited securing and training personnel as challenges, and decided to consider updating in order to use the time required for equipment repairs and maintenance for personnel training.

To solve these problems, we proposed the DNS-850 fully automatic non-tank pressure test equipment.

The DNS-850fully automates the processes of water injection, pressure testing, drainage, and drying for two bottles simultaneously. This makes it possible to increase the number of bottles that can be processed in the same space as existing equipment. In addition, because cylinder data and test results are transmitted online to a computer in the office, there is no need to manually input cylinder information and test results, and this also helps prevent human error.

Benefits of Implementation

He cited two major benefits of implementing the system.

①By improving the efficiency of the equipment and utilizing the system, overtime hours can be reduced

②Shorten delivery time by issuing labels in-house

①By improving the efficiency of the equipment and utilizing the system, overtime hours can be reduced

The efficiency of the equipment can be seen in more ways than just increasing the number of bottles processed. Before the upgrade, workers had to check which process cylinder was in (water injection, pressure test, drainage, drying) and move to each process location to operate the switch to start the process. After the upgrade, once the system was started, there was no need to operate each process, and workers had to move around and check things less. In addition, the control panel display clearly shows the work process, making it easy for foreign technical intern trainees to operate. After the upgrade, workers were seen to be more proactive in their work, and it seems that the company's overall problem of lagging behind in training is also moving in the direction of improvement.

In addition, with this new system, we now receive data such as the stamp numbers and tare weights of all cylinder from our customers and register them all at once in the system. As a result, we no longer need to manually register cylinder data one by one, which has led to a significant reduction in overtime hours.

↑Each process of water injection, pressure testing, drainage, and drying is displayed on the display of the equipment control panel.

②Shorten delivery time by issuing labels in-house

Previously, when changing the format of the labels to be affixed to cylinder, we had to order them from an outside company, but now we can customize them in-house.Shorter delivery times and improved customer servicecontributes to.

In addition, at the request of Utsunomiya Propane Co., Ltd., we used the team color pink on the equipment, conveyors, and computer screens. You can see from the photos that the inside of the factory has become brighter compared to before the equipment was introduced. They said that just having a brighter interior changes their motivation to work.
