Bladder Tank Installation & System Design Information The Chemguard Bladder Tank is one component in a balanced pressure foam proportioning fire protection system. It requires no external power other than water pressure to ensure correct operation. The bladder tanks are designed and constructed in accordance with the latest revisions
8 sty 2019 · The bladder tanks are designed and constructed in accordance with the latest revisions to ASME Code, section VIII for unfired pressure vessels with a working pressure of 175 psi and are tested to one and one half times this pressure. INSTALLATION.
The Viking bladder tank is a carbon steel pressure vessel (stainless steel construction optional) containing an elastomeric separation bladder between the water and foam concentrate. The bladder permits water pressure to be transferred to the foam concentrate without the two fl uids mixing together. A Viking ratio controller, as
1 lut 2018 · The bladder tanks are designed and constructed in accordance with the latest revisions of european community`s pressure equipment direction (PED) and carry the CE marking with a working pressure of 175 psi (12 bar) and tested to 228 psi (15.7 bar) pressure.
The vertical and horizontal bladder tanks are designed and construct- ed in accordance with the latest revisions to ASME code, Section VIII for unfired pressure vessels with a working pressure of 175 psi and tested to 1.3 times this pressure.
The Bladder Tank Proportioning System employs water to pressurize the bladder and force foam concentrate to the ratio controller. The water supply simultaneously feeds the ratio controller and the bladder tank. As water flows through the ratio controller the level of pressure reduction increases, thereby affecting a corresponding pressure drop
Bladder Surge Tanks. Water hammer and surge protection for potable water, sea water and wastewater systems. The bladder surge tank serves as an important component of combined surge protection systems protecting against both positive and negative pressure surges.
