I went to local hardware store and found tons of pipe and pipe fittings.a)Whats the difference between galvanzied pipe and black pipe? Are the threads different? Applications?b)I was looking at the thickness of the walls for 1/2 vs 3/4 vs 1& vs 1.25&, etc. etc. Is there some site that shows the I.D and O.D and wall thickness for the standard pipe sizes above?c)Comparing 1& pipe vs 1& Nipples, I noticed that the Nipples have much thinner walls. Any idea or do you know of a site that lists load limis for certain diameters / spans of pipe?d) For galvanized pipe and/or black pipe, do all threads taper inwards regardless?e) Last question, TY so much for helping. If I drill a 1/4& hole smack in the middle of a 45 or a 90 or a T, does this dramatically affect the structural integrity of the fitting. Assume 1'TY
why would you want to light insects on fire?! thats soo mean but if it makes you happy then GO FOR IT!!!!
Try it there is only one way to find out.
No it wouldn't. In fact, not only will the speed bumps be ineffective against slowing the cars down, it would affect the handling of the cars. it would make the sport a little more unsafe.
I don't have any statistics, but if you're in a city surrounded by tall buildings, the lightning would be much more likely to strike one of the buildings rather than a person on the ground.
yes u can but if the smoke become too hot and the ceiling heats up then the alarm will go off, its not do by the heaviness of smoke its by heat., so yea u can i do every day
