We would like to introduce a case study of an in-house manufactured can tank that we handled. We received a request from a nearby customer for the replacement of two aging cone-roof tanks. Essentially, it was a replacement project with the same specifications (materials, dimensions, etc.) as the existing tanks. However, due to the lack of detailed drawings for the tanks and their supports, we created manufacturing drawings using 3D scanning. Since we were able to accurately create the drawings and manufacture the tanks, the connections to the existing piping and walkways were almost seamless, resulting in a shortened construction period. [Case Overview] ■ Manufacturing Period: Approximately 2.5 months after material procurement ■ Material: SS400 ■ Size: IDΦ2330×4900L ■ Applicable Regulations: None ■ Total Capacity: 20.25m3 ■ Contents: Crude Oil *For more details, please refer to the PDF document or feel free to contact us.

Please feel free to contact us if you have any requests. 【Process Flow】 ■STEP 1: Specifications ■STEP 2: Design (Creating drawings while consulting with the customer) ■STEP 3: Manufacturing (Manufacturing parts and assembly based on production drawings, conducting trial runs in-house) ■STEP 4: Installation (Installing and handing over to the customer) *For more details, please refer to the related links or feel free to contact us.

Starting in 2023, our company has introduced a mobile three-dimensional measuring machine capable of measuring large objects up to 25 meters in size. Previously, we used a stationary three-dimensional measuring machine for measuring the dimensions of parts, but now we can also perform three-dimensional measurements of tanks and similar objects. Using an infrared probe, we can remotely measure parameters such as the height and flatness of nozzles. The position and angle of nozzles, which were previously difficult to measure, can now be accurately and easily measured, and the circumference of tank bodies, which required two people using a tape measure, can now be measured by one person. *For detailed information, please refer to the related links. For more information, please check the PDF materials or feel free to contact us.

We would like to introduce a case study of the skid equipment we have handled. The drawings were provided by the customer, but they appreciated the advantage of our ability to carry out everything from tank fabrication to piping and operational confirmation in a consistent manner. The drawings in the customer's possession were only old hand-drawn plans, and there were few people who understood the technology of that time, making production very difficult. However, despite this situation, our company had previous experience with the same project, and by utilizing our manufacturing know-how, we were able to respond creatively, which was well received. [Case Overview] ■ Production Period: 4 months ■ Material: SS400 ■ Size: 3000mm x 5000mm *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the microfilter unit we produced. It features an interior surface finish of #400 buff and is part of a pharmaceutical manufacturing line. Since it was equipment for pharmaceuticals, there were many documents and necessary inspection items to submit. To obtain material certifications for the piping and gaskets, we closely coordinated with the technical and manufacturing departments. Additionally, we paid extra attention to the surface treatment of the inner piping and the welding beads. 【Case Overview】 ■ Production Period: 3 months ■ Material: SUS304 *For more details, please refer to the PDF document or feel free to contact us.

There are detailed regulations, but to put it simply, it is a container that generates steam in various ways regardless of its size, and holds a liquid that exceeds atmospheric pressure or the boiling point at atmospheric pressure inside. *Due to the high risk associated with tank failure, structural inspections and welding inspections are mandatory. Our company manufactures tanks after undergoing a pressure inspection by the Japan Boiler Association and obtaining permission.
