EXTERNALLY PRESSURISED EXPANSION JOINTS's TECHNICAL INFORMATIONS.
Odcedite
Da bi se izognili koroziji, je morda zaželeno imeti možnost odvajanja medija, ki obdaja zunanje tlačne raztezne spoje. To je mogoče s to zasnovo dilatacije.
Pokrov
Externally pressurised expansion joints's cover is often subject to relatively high stresses through the combination of diameter and pressure with the choice of material for the cover being based on the operating conditions.
V nekaterih primerih lahko jeklo visoke trdnosti zmanjša skupno težo enote v primerjavi z običajnimi vrstami jekla.
Ker so zavoji zunanjih tlačnih razteznih spojev dobro zaščiteni pod pokrovom, je malo verjetno, da bi prišlo do transportnih poškodb na zvitkih, najpomembnejše pa je, da pokrov nudi maksimalno zaščito pred puščanjem meha ali okvaro meha.
Zunanji tlačno uravnotežen valoviti kompenzator je vrsta opreme, ki v osnovi rešuje problem potiska sile slepe plošče na fiksno oporo, poenostavlja načrtovanje in konstrukcijo fiksne podpore ter zmanjšuje stroške projekta.
Zunanje tlačni raztezni spoji so popolna rešitev, ko morajo dilatacijski spoji pod visokim pritiskom absorbirati zelo velike aksialne premike. Načeloma ni omejitev glede velikosti aksialnega gibanja, ki ga lahko absorbira ta vrsta dilatacije.
Zunanji tlačno uravnotežen valoviti kompenzator lahko kompenzira aksialni premik v cevovodnem sistemu, zunanji tlačni potisk pa je samouravnotežen. Konstrukcijo je mogoče uporabiti v cevovodu visokega položaja objekta, kjer fiksna podpora ni primerna.
In externally pressurised expansion joints, the bellows element(s) is arranged so that the media flow is on the external side of the bellows, while the inside part of the bellows is only subjected to atmospheric pressure with this side being in direct connection with the atmosphere. External pressurising of the bellows eliminates pressure instability as a design limitation and permits the absorption of large axial compression. Where an internally pressurised bellows will become unstable and buckle due to internal pressure, the pressure around an externally pressurised bellows will have a stabilising effect on the bellows. This makes it possible to achieve a construction of externally pressurised expansion joints with great flexibility for large axial compensation. With only the outside of the bellows subjected to pressure and the convolutions packed under a cover, the perfect conditions for external insulation or underground installation can be achieved.
