No because its not rated for AIR lines and plus if you were to use it and something damaged the pipe it would explode. Most people use copper or iron pipe for air lines.
On commercal and other air line installations black pipe is the normal material to be used , depending on a the working pressure then one would choose the schedule of the piping and fitting rating
water line? half inch or three quarters
The answer depends on the flow rate or the water pressure, not just the pipe size.
line segment to the nearest half inch is measured using the distance formula.
Depending what you are wanting to supply. Basin, shower, toilet, bidet, kitchen can be fed with a half inch line Main line and bath can be fed with a three quarter inch line
By the use of Flagg Flow T.P Fitting adapters and Cx M or C x F adapters attached to the T.P fitting T.P = threadless pipe
I would use 3 inch for that.
This problem lies with your pipe sizes. If the pipes size of your main line does not equal the supply for demand this will result in the current problem. For example, if your whole house is fed with half inch piping and you open two taps the volume of water has to be shared from the half inch pipe, thus causing a drop in pressure. Whereas if one installed three quarter inch main line "t-ing" off to half inch, because the three quarter inch will hold a higher volume of water when two taps are opened and the water shared, the drop in pressure will be hardly noticeable.
A handheld bandsaw or a cutting torch, along a straight line made by a wraparound pipe marker. our company has the steel pipe machine and you can cut it in 4 inch-haihao pipe fitting group sales@haihaogroup.com
about a half an inch
In Tulsa Oklahoma you can, but i would still use 4 in.
Most of the time it is 4 inch.
a 3 inch pipe
