In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
