STRAUB SQUARE-FLEX
Straub connects square pipes easily, quickly and reliably with STRAUB-SQUARE-FLEX. The main application area of STRAUB-SQUARE-FLEX is piping in water treatment plants for biological waste water purification. Straub Square Flex is used on square pipes in aeration basins.
STRAUB pipe couplings designated with FLEX are axially flexible (non axial restraint)
If STRAUB-FLEX pipe couplings are used, it must be ensured that occurring axial change in each pipe section is not greater than the compensation capability of the used STRAUB-FLEX pipe coupling. A fixed point and a sliding pipe restrain are required for each pipe section.
