What is a flexible connector in the first place?? In simple terms, it is a "soft, stretchable, compressible, and bendable pipe" used for the purpose of "protecting solid objects with its flexibility and supporting smooth movement." 【Where flexible connectors and expansion joints are used】 ◆ Moving parts of machinery ◆ Inlet and outlet of rotating equipment such as pumps that experience vibrations ◆ Inlet and outlet of fragile tanks, chemical tanks, and other tanks with leakage risks ◆ Piping that experiences movement due to thermal stress or water hammer The important thing about flexible connectors and expansion joints is understanding what kind of movement you want to absorb. The main types of displacement (movement) can be broadly categorized into two: "expansion/contraction" and "eccentricity," with "composite displacement" occurring when both happen simultaneously. You must select the "movement" and the corresponding "material" for the fluid, but the most crucial point is to choose and manufacture flexible connectors made from materials that meet the usage conditions (pressure, temperature, fluid) and environmental conditions (exposure, burial, outdoor, gas atmosphere). There are many considerations in the selection process, and data backed by experience and proven results is essential. Our specialized technical sales staff will propose the optimal flexible connector, so please feel free to contact us.

We have renewed our vol.1 catalog, which includes frequently inquired items such as PTFE flare hoses, silicone hoses, ferrule lining pipes, and sanitary lining valves. Although it has only been about two years since the last catalog revision in 2020, approximately 30 new products have been added to the lineup. Additionally, the structure of the catalog has been changed, making it a much more comprehensive catalog with content beyond just products. If you would like a copy of the new catalog, which features many new products, titled "Tōkatsu Techno Product Catalog vol.1 4th Edition 2022," please contact us through the 'Inquiry' section below.

In various regions of Japan, earthquakes are frequently observed, which has heightened awareness of crisis management. However, amid rising prices and a sluggish economy, there are not many companies willing to invest in earthquake countermeasures. Previously, there was an incident in Wakayama where a water bridge collapsed, leading to a water supply disruption. The realization of inconvenience in daily life, where everything operates without issues, fosters a sense of crisis. Particularly, factory piping and infrastructure piping carry a vague risk of "having to do something someday." What can be done to reduce the risk of disasters? The answer lies in our company, "Tōkatsu Techno," which manufactures "flexible joints." "Flex" and "expansion joints" are essential items that enhance the safety of piping carrying hazardous fluids such as chemicals, serving as "cushions and joints for piping" that protect against shaking and vibrations from earthquakes. Our company offers various solutions, especially with our optimal 【Teflon (fluororesin) flex】 for particularly hazardous fluids. If you are looking for flex, hoses, or expansion joints for equipment or systems that are anxious about earthquake countermeasures, please feel free to consult us. Our specialized technical sales staff will provide you with the best proposals.
