Unthreaded galvanized pipes can be difficult to connect. To put it another way, you can’t just screw two pipes together to seal them. But doesn’t that imply that connecting them is impossible? There are numerous methods for connecting galvanized pipes without threads.
To connect two pipes, screw them together or use pipe thread tape. Another option is to weld the pipes together or use couplings to connect them.
This post will have an expert guide on how to connect galvanized pipes without threads.
Tools You Will Require:

How to Connect Galvanized Pipe Without Threads: Step-by-Step Instructions:
To connect galvanized pipe without threads, you need a stainless steel coupling that tightly seals the connection or you can do it by using galvanized Pipe fittings. As a result, proper coupling is required to keep pipes from leaking.
Due to the zinc coating and rough surface of galvanized pipes, joining two pipes together can be difficult.
Connecting non-threaded galvanized steel pipes let’s get started.
Step 1: Determine the Diameter of the Pipe:
Using a tape measure, determine the outer diameter of each unthreaded galvanized pipe. If the two pipe diameters are the same, use a standard coupling. If there is a diameter difference, use a stepped coupling.
Step 2: Determine the Pipes’ Smoothness:
Examine the pipe’s Galvanized Coating to see if the coating is rough or smooth. There are two kinds of galvanized clutches available: rough surface coupling and smooth coupling. Choose a more textured grip if you have uneven pipe surfaces.
Step 3: Examine the Pipe’s Squareness:
Check the squareness of the non-threaded galvanized pipe with a level. If not, use a hacksaw to cut it flat. After that, use a metal grinder to smooth out any rough edges on the pipe.
Step 4: Cleaning the Galvanized Pipe:
Use water-based degreasers and pipes to clean non-threaded galvanized pipes. This will aid in the removal of dirt and grime from the clutch area. Align the pipe ends and place the coupling in the center of the pipe joint. Draw a line where the coupling ends on each pipe with a pencil.
Step 5: Install the Unthreaded Galvanized Pipes:
Insert one end of the non-threaded galvanized pipes into the coupler. Align the hitch’s end with the line drawn in step 4 above. Insert the second pipe into the coupler and align it with the two lines you drew earlier.
Step 6: Tighten the Fastening Bolts:
Tighten the fastening bolts until the coupler is securely fastened to the non-threaded galvanized pipes. Tighten all of these bolts evenly to the torque rating marked on the clutch with a torque wrench until you hear the wrench click.
Various Threadless Connection Methods:
Non-threaded connection methods are classified into two types: welded processes and non-welded processes. Fusion and pressure welding are two processes ideal for heavier gauge galvanized tubing.
Couplings (described above), flange joints, pull joints, and Gebo fittings are non-welded methods of joining galvanized steel without threads.
Considerations When Connecting Non-Threaded Galvanized Pipe:
Connecting galvanized pipe without a step is a process that necessitates some important considerations.
When connecting non-threaded galvanized pipe, the following factors should be considered.
The diameter of the pipe is an important factor in determining the type of coupling that can be used. Use a standard coupler if the two pipes are the same galvanized 3/4 diameter or another common pipe size. A stepped coupling is required if one pipe is larger in diameter than the other.
The Galvanized Surface Texture:
Galvanized steel pipe can have a smooth or rough surface. The texture of the coupling should be consistent with the texture of the pipe. Smooth pipe works well with smooth joints, while rough pipe works well with rough joints.
Pipe End Squareness:
Pipes with right angles must have their ends aligned to form a joint that joins the pipes seamlessly and without gaps. If not, I recommend using a hacksaw to align the tubes properly.
Another critical factor to consider is the method of connectivity. Depending on the situation, one of the above welding or non-welding techniques can be used.
It should be easier to deal with emergencies around the house now that you know how to connect galvanized pipe without threads.
There are several methods for doing this, including welded and non-welded methods. This means you can select the most convenient method for you while still producing effective results.
The most common method used by homeowners is couplers. We have already provided a step-by-step guide for the method above. There’s no doubt that after reading this guide, you’ll be able to create a reliable seal between these unthreaded galvanized pipes easily.
1. How does one connect a galvanized water pipe?
They can either temporarily or permanently plug galvanized pipes.
Galvanized pipe fittings, such as plastic caps, can be used to make a temporary plug. Is necessary. There is also a metal cap available. Solder the ends of the tube you want to cap if you want long-lasting results.
2. How do you repair a rusted galvanized pipe?
It is simple to repair a broken galvanized pipe; simply replace the damaged part. This means you can use your preferred method to connect two pipes by creating two connections.
3. Can compression fittings be used on the galvanized pipe?
Yes. Conditioner couplings and other compression fittings work with galvanized pipe. Connects threaded and non-threaded pipes.
4. How do you join galvanized and copper pipes?
Soldering can be used to connect galvanized pipes to copper pipes. Smooth out the joint with sandpaper once it’s clean.
