At what PSI does a plastic soda bottle explode? (home CO2 carbonation)

This tire volume calculator works better: http://www.club80-90syncro.co.uk/Syn...calculator.htm My P225/55R16 Traction=A, Temperature=A, Treadwear=480 car tires calculate to 14.76 liters each (60 liters for four tires). So a four-foot manifold with eight 2L Coke bottles hanging down would completely fill one tire. |

From: Coca-Cola Support Thank you for contacting The Coca-Cola Company. We appreciate your interest in our Company and our brands. As you know, the amount of PSIs (pounds of pressure per square inch) that a package is able to withstand depends on the volume of carbonation and is based on the product as much as the package. At lower temperatures, the pressure is lower, and at higher temperatures, the pressure is higher. Carbonation is measured in "volumes." One volume of CO2 is equal to one liter of carbon dioxide dissolved in one liter of liquid at standard temperature and pressure. Two volumes are equal to two liters of gas in one liter of liquid, etc. The amount of CO2 absorbed by the liquid is a function of temperature and pressure. The colder the liquid and the higher the pressure, the more CO2 it absorbs. One volume is equal to 14.7 lbs. per square inch (psi) pressure at sea level and at 60º F. All PET packages can withstand 150 PSIs - the industry standard. However, some of our PET packaging can withstand 250 PSIs. Unfortunately, we will not be able to provide a list of which ones can withstand 250 PSIs. We certainly appreciate your interest in our production processes for our brands. However, in order for us to remain competitive in our industry, some information is considered proprietary, and we are unable to share it with the public. We hope this information is helpful. Please feel free to contact us again should you have any other questions or comments. Sincerely, Johnetta Industry & Consumer Affairs The Coca-Cola Company |

That horn was really too loud and now I can attenuate it so the target doesn't die of a heart attack. It gets so messy when that happens. I have to attach it to my new bike. I don't bother using it during the winter because there aren't that many joggers clogging the bike lanes. Now they're out in full force. |

I hydrostatically tested one at 150 psi (a cheap thin one) and it was
just fine. HTH :-) Bob |

For just the rubber tire assembly, the total volume p × (5 dm ¸ 2)2 × 1.5 dm = 29 cubic decimeters (i.e., 29 liters). The volume difference is just 10 liters (which means that the air in the tire will mass about 26 grams).

This volume calculation puts a car tire at 1 to 2 cubic feet of air: http://mgaguru.com/mgtech/tools/ar104.htm BTW, what happens to the mass if we use a different gas than air, like carbon dioxide? Many people are using nitrogen in their tires now and paying a premium for it. The benefits are not so from the physical qualities of the gas, but the fact that the gas contains absolutely no water. So the tire pressure changes less due to temperature changes. |

Many people are using nitrogen in their tires now and paying a premium for it. The benefits are not so from the physical qualities of the gas, but the fact that the gas contains absolutely no water. So the tire pressure changes less due to temperature changes. Some of the benefits most certainly are from the physical properties of the gas. Aside from the benefits due simply to lack of water vapor, the hydrogen migrates less thru the tire structure and that makes the tire pressure stay up longer then when you use plain old air. In addition, the nitrogen does not oxidize the tire materials the way the oxygen in plain old air does and that also is beneficial to tire life. All that said, for most people the benefits of nitrogen are relatively small and if you pay much for it you may not recover that extra cost. For truckers the benefits are much greater,particularly the benefits of the tire components not being oxidized since they will retread a truck tire many times over it's carcass life. And with nitrogen the carcass will last longer. |

I've heard that you can use metal lamp connector rods that are threaded on both ends. Apparently someone did that with water bottle rockets. http://h2orocket.com/water-rockets/lamp-rod-rockets/

When I was stationed in California, back in the 80's, I used to belong to the "Soda Butler" service. Monthly they'd bring a new CO2 cylinder, the soda syrups of your desire, and new 2 liter bottles, if need be. The regulator was set to 5psi. You'd add syrup to a line, fill with filtered water, unless you liked chlorine tainted soda, place the special cap on the bottle, (which had a heavy duty schrader valve) connect the hose to the bottle cap valve, and shake, shake, shake. I found that the longer you shaked the more CO2 would "scrub" into the liquid, so I could control the amount of fizz. It was a great system as I never had any flat soda, no matter how long it was left in the fridge, just scrub (shake) more CO2 into the liquid and like magic, fresh fizzy soda. Shaking was mandatory to scrub CO2 into the liquid at 5 psi! Hope this helps! -- for full context, visit https://www.homeownershub.com/mainte...ca-434649-.htm |

At 150 PSI, they would be useful as expansion tanks for air compressors. Now, someone to make a manifold so we can string together a bunch of two or three liter bottles. Watch. Harbor Freight will have them next week.
============================== Careful! If the plastic bottles are right off the compressor the air will be hot and that's a game changer for the plastic bottle specifications. It may work if the bottle storage was well down stream, and away from the heated air, maybe at the point of use. While It may be tempting to reuse bottle caps for a DIY manifold, I wonder if the cap 'seals' are for tamper proofing or do they aid in securing the cap with higher pressures? I don't know but it could be exciting to find out! I think metal, or solid plastic caps are available online that would be more suitable. I use 2L bottles, pressurized to about 50 PSI to dispense lubricant to a CNC router cutter when machining aluminum. So far there's been no problem at that pressure and I reused a cap. The lube is water based and there's been no plastic reactions either. Might be a worthwhile idea idea to put the 'air bottle' in a PVC tube just in case there is a problem. I have my 'dispenser' bottle in a PVC pipe with a glued bottom cap and a slip fit top cap to allow pressure release and changing, yet still provide fluid containment which should help any embarrassing Uh Oh's ! Good luck, and post your success. Remember that there are 'no failures'. They are just a long list of things that don't work! -- For full context, visit https://www.homeownershub.com/mainte...ca-434649-.htm |

Elmo,To say at what P.S.I a plastic soda bottle will rupture is not possible due to the numerous manufactures that produce soda bottles at a non-standard thickness or grade of material. WHOLY SH^T Elmo! 150 PSI??!! DUDE BE CAREFUL! you can loose a finger with that much PSI. Check out this expierment. m

That looked like a lousy bottle, and the bottle never broke. It was the cap that did, every time. Drilling holes in the cap does not help it's strength. I've had bottles of cider that naturally fermented that were rock hard. It took me days of frequent slow bleeding by loosening the cap a tiny bit to get them down to where I could open them to drink. I have never had one break. 2L bottles. |
