Re: working with spiral pipe

 

Just as a point of clarification, when discussing sheet metal or wire ¡°gauge¡±, the lower the number the larger (thickness, diameter, etc) the dimension. For example, for bare sheet metal 16ga is about .060¡±, 10ga is about .135¡±. The values change for brass, aluminum and other alloys and also for wire but the concept stays the same, lower number = larger dimension. For sheet metal the best I have been able to determine is that for a fixed volume, say 12¡±x12¡±x12¡±, the number of 12¡±x12¡± plies needed to stack up to 12¡± is smaller for thicker material and larger for thinner material. The methodology used to determine the seemingly random gauge thicknesses is still a mystery to me.

?Air Handling is a good supplier of spiral goods: Airhand.com.? They have the straight section joint pieces I mentioned.

CarolinaAirSystems.com is my favorite snap lock supplier.??

Hi Bird,

¡°Maybe I¡¯ll try something lighter gauge as you suggest, Imran.¡±

If by that you mean HVAC fitting to connect then yes. If you mean spiral pipe than that is not what I suggested. I like the heavy gauge pipe I got from Rockler. Like others have suggested just screw or rivet. I also used AL tape to seal and yes, it is hard to remove.

Definitely pre drill. I even connected some cast AL blast gates to spiral pipe with screws.
