What is a flexible joint, to begin with? 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 to use flexible joints and expansion joints】 ◆ Moving parts of machinery ◆ Inlets and outlets of rotating equipment such as pumps that experience vibrations ◆ Inlets and outlets of fragile tanks, chemical tanks, and other tanks with leakage risks ◆ Piping that experiences movement due to thermal stress or water hammer The important question regarding flexible joints and expansion joints is: what kind of movement do 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 "material" that corresponds to the fluid, but the most crucial point is to choose and manufacture a flexible joint made of a material that matches the usage conditions (pressure, temperature, fluid) and environmental conditions (exposure, burial, outdoor, gas atmosphere). There are numerous considerations in the selection process, and data backed by experience and proven results is essential.
