Can you mix black pipe with copper pipe on same low pressure system?
Andypad
It is not the type of pipe that is important, it is what you are putting through it. Copper is commonly hooked to black pipe for gas lines. Black pipe for natural gas or propane and galvanized for water. Either can have copper attached to them.
Due to the electrolytic decay caused by attaching dissimilar metals, you would need to use a dielectric union to connect galvanized steel to a copper pipe; otherwise the joint will rot away in a few years, assuming there is any moisture around the joint. Properly dried gases may not have this problem.

In air conditioner units is the larger copper refrigerant pipe the low or high pressure side of the system?
it is the low pressure side
Are there any problems connecting copper pipe to brass tee from pressure tank?
none whatsoever, the metals are related. just do not use black metal pipe
How do you repair a pinhole in copper pipe?
Use a lead-free silver solder. It is the only thing that can handle the pressure and bond with the copper pipe.
Will methane gas turn copper pipe black?
no
How much air pressure can copper pipe hold?
2000 Psi
How much water pressure in a copper pipe?
up to 2.300 PSI
What is the maximum pressure of a 1.250 pipe?
depends on the pipe like if its copper its rated at 300 psi 200 degree F pvc is rated at 200 psi schedule 40 if its black poly it would be 200 psi most all pipes have it on the side of the pipe ,pressure and degrees.
How do you know if you have copper or steel drinking water pipes?
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
Can a 2.5 galvanized dielectric union be used to connect black pipe to copper pipe?
Yes
Can you use brass as a dialectric union between copper and black iron pipe?
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
Can pex pipe be used for propane?
No, it is made for water only. Black iron pipe or copper are only allowed and a special plastic coated copper for underground installations.
What is the flow rate for 28mm copper pipe?
To provide an answer to this question the pressure of the fluid applied at the input end of the pipe must be provided.
