Sorry smart one, but if you were on a so called “science team,” you wouldn’t be giving incorrect information about schedule 40 and schedule 80 PVC piping on a flamethrower thread. Schedule 40 and 80 have a multitude of different PSI ratings depending on the nominal pipe size and whether it is schedule 40 or schedule 80. The maximum operating pressure (depending on the size) can be anywhere from well below 150psi to well above 150psi. Those are safety ratings. All of the sizes do have a required minimum burst pressure that is anywhere from around 400psi to around 2500psi depending on the size of the pipe and whether it is schedule 40 or 80.

now first things first sch 40 pvc and sch 80 can be used with pressure up to 150psi. also the only thing that would weaken pvc is paint lacquer me and my science team specialize in this kind of stuff.

I with a friend made one of these and it exploded just like I thought it would 50 lbs pressure. I am going to make another one but only to shoot insecticide only. Adults, kids whatever do not use it for a flame thrower trust me on this. If I ever made a flame thrower it would be made out of steel. On the pvc it tells you plain as day not for pressure. Plain as I can say it do not make one. Ray

Can anybody say what PSI pressure is being used in this flame thrower? I am trying to make it but i am not sure of the psi.

try filling it with paint fill, and leaving the whole, “flaming/exploding/death” part out

yes military use napalm-that s disolved polystyren in gasoline

This is a 100% instruction to blow yourself up.

Alcohol and gas combined with pressurized air is hihgly explosive.
(No military guy would use that)

You have no commercial-grade back-safety nozzles in the circuit, your system is built from plastic, you must build it from metal and without pressure in the main tank, do not use AIR as pressurizer, etc…

Once the tank is empty, and full of vaporized gas, you WILL blow yourself up eventually. No question on that.

thanx brother, i made a similar thing but much smaller and fixed it in our remote controlled robo car, and everyone in the robo fight contest were f***ed up, we fried their a** to stone age

keep up the good work bro

better ideas:
Use a powerwasher gun instead of the metal pipe thing.
Add some check valves in case the flame siphons back into the tank (blowing it up)

damn this thing looks like a great model, all the other stuff is made out of squirt guns

Military models use a sticky “jellied” mixture that adheres to whatever it contacts until the fuel runs out. Nice effort, however…
