How to Connect Non-Threaded Galvanized Pipe?

You are currently viewing How to Connect Non-Threaded Galvanized Pipe?

Are you struggling to know how to connect non-threaded galvanized pipe? Connecting the non-threaded galvanized pipe jointly utilizing couplings that structure locked joints. You must know the type of coupling that you are using for galvanized non-threaded pipe fittings and also the installation process to avoid pipe leakage. Well, we have to go through the process to connect non-threaded galvanized pipe!

The Process to Connect Non-Threaded Galvanized Pipe

You have to follow the below-mentioned steps to connect non-threaded Galvanized Pipe:

  • First of all, you have to measure each Pipe’s outer diameter, for this, you have to use a tape measure. Then, you have to select a standard coupling in the situation if the diameters match correctly. But if the diameters differ, you have to choose a stepped coupling.
  • In the next step, you have to analyze the pipe’s galvanized surface to specify that is the coating smooth or rough. Then, you have to select a coupling manufactured to adjust rough surface pipes, in situation if the galvanized coating seems and senses textured. So, you have to request for a “rough surface” coupling reasons that these have tolerances uneven pipe surfaces’s all types like concrete and cast iron pipes.
  • Now, in this step, align the level of a carpenter against the non-threaded pipe’s end so that the end is fair and square. After that, by using a power saw or hacksaw, you have to cut the end to a court or square each pipe if your sto end is rosypipe ends have been removed with the pipe end’s rough edges with the help of a metal sander.
  • The next step is to wipe the pipes using a clean cloth and by using a water-based degreaser. You have to do so to remove dust, dirt, and stains on the coupling area. You have to put the pipes end together. Then, you have to center the coupling on the pipe joint, after that, you have to point out a pencil line on each pipe at coupling’s each end.
  • After that, you have to insert the non-threaded galvanized pipe’s one side into the coupling. Now, you have to align the coupling end with a drawn line on the pipe. Now, you have to put in the second pipe into the coupling. Then, you will center the coupling between the two drawn lines.
  • In this last step, you have to tighten or pull the fastening bolts until the coupling simply keeps the galvanized pipes in place. You have to use a torque wrench set at the marked torque requirement of coupling to evenly attach the bolts till the time the wrench clicks off.

Clean Galvanized Steel Pipes

To clean the galvanized steel pipes, you have to follow these steps:

  • Firstly, you have to combine 1-gallon hot water, 1 cup vinegar, and 1/4 cup dishwashing detergent in your bucket.
  • After that, you have to dip a soft brush into some soap solution. And then, you have to scrub the pipe with the help of a small circular swirls.
  • Now, you have to rinse the pipes using some hot water and then dry them.
  • Then, you have to apply metal polish with the help of a lint-free rag in little circular rotations.
  • Now, you have to let the metal be non-threaded then you have a wipe clean.


How to Connect PEX to Galvanized?

For this, you have to install a threaded transition fitting to proceed from galvanized pipe/fitting to PEX tubing. Depending on the type of PEX fittings manipulated, a dielectric union might be required. Unite the PEX tusing to the fitting taking up a compatible procedure. You have to check the connection for precision.

Can Galvanized pipe and PVC be Connected?

Yes, PVC and Galvanized pipes can be connected. For this, you have to require an adapter for the size pipe that you are connecting. There are several choices, but the better option for you is that you should go to a hardware store, or go to a plumbing supply store that deals with people to get what they need.

How to Join a Galvanized Mild Steel Pipe and Fittings?

With the help of bolting (containing friction grip connections), riveting, adhesive bonding, and welding, you can join galvanized articles. In this sense, bolted joints are better completed after galvanizing. And the welded sections require to be reconditioned the procedure will result in any localized crack and damage to the coating.

What Kind of Pipe Joints is Normally Used for Galvanized Steel Pipes?

Normally, to connect steel pipes able fittings can be used. Yet,  you need to use galvanized malleable fittings for galvanized pipe. The most ordinary thing is Malleable iron pipe fittings among malleable fittings. They are also obtainable in multiple different types and different sizes.


Connecting non-threaded galvanized pipe is not very difficult. You just have to follow the above-mentioned process carefully. Hopefully, you have got a lot of information after reading this article!
