3/4 in. x 48 in. Black Steel Pipe

Hi John, this was calculated using several variables: Inner Diameter, Outer Diameter, velocity, temperature and pressure. This flow rate of 16.6 GPM is based on a 3/4-in pipe transporting water at 72-degrees Fahrenheit. This can change based on the medium being transported as well as temperature and pressure. We hope this helps with your project.

Hi Ron, we recommend using alternative piping methods for water applications as water will begin oxidizing upon contact. If you check local plumbing code, you should be able to identify several alternative project materials for your need. We hope this helps with your project.

Hi Jim, for this type of application we recommend checking local codes for recommended materials & installation guides. We hope this helps with your purchase.

This is pretty stiff. A cinder block on a 48in pipe won't deflect it much. I use them for furniture clamps (HD sells the clamp kits if you are interested)

The outside diameter of black steel pipe is not controlled closely enough to use inside a pillow block. It would either not fit, or be sloppy. You could turn the end smaller (using a lathe), but you should plan to use a different product where the OD has a closer tolerance and is designed to be used as an axle shaft.

1.05" O.D.

Yes, That's the reason I bought this product.

No, there will be a small ID bead. 2" and above has the bead scarfed out

Yes, I'm using this for my pipe clamps.

Yes 700 P.S.I.
