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.
