What You'll Learn
Using flange designs with set screw couplers
Flange designs with set screw couplers are a common solution for mounting conduit to a flat surface. This combination provides a secure mounting point for EMT conduit, making it suitable for lightweight, non-structural projects.
The set screw couplers can be easily sourced from local hardware stores and come in two varieties: threaded and compression fittings. The threaded type has threads on one side that can be screwed into the flange, while the compression fittings have a nut that tightens the pipe into the fitting.
To install, simply thread the set screw coupler into the flange. Then, insert the conduit into the other end of the coupler and tighten the set screw to secure the conduit in place. For an even more secure connection, you can remove the set screw and use a self-tapping screw instead.
Additionally, you can enhance the security of the setup by adopting techniques such as using a galvanized steel pipe nipple, drilling through the pipe to add a nut and bolt, or inserting a threaded pipe insert into the conduit. These methods can be used individually or in combination to achieve the desired level of security for your project.

Threading EMT conduit directly into cast iron flanges
One of the most common challenges in building projects is figuring out how to mount conduit to a flat surface. One solution is to use flanges, which can be purchased at your local hardware store in either 1/2" or 3/4" threads. These flanges are typically made of cast iron and come in black or silver.
You can achieve a decent flange connection by threading EMT conduit directly into these flanges. However, it is important to note that this method is not suitable for all applications. It is best suited for lightweight, non-structural projects.
To begin the process, select the appropriate flange size and thread the EMT conduit into the flange. You can then add the conduit into the other end and tighten it with a set screw until it is securely fastened.
Another option is to use compression fittings, which function similarly to set screw couplers. One end threads into the flange, while the other end has a nut that secures the pipe as you tighten it.
It is worth noting that some sources suggest that EMT conduit is too thin to thread effectively and may not provide sufficient strength for certain applications. However, with the right materials and techniques, it is possible to create a secure connection by threading EMT conduit directly into cast iron flanges for lightweight projects.

Using compression fittings with flanges
Compression fittings are used to connect tubing to threaded components like valves and tools. They are commonly used in hydraulic, gas, and water systems. They are especially useful when occasional disassembly or maintenance is required, as they can be easily broken and remade without affecting the integrity of the joint. Compression fittings are also ideal for situations where a heat source is prohibited or where it is difficult to remove water from inside the pipe.
There are two types of compression fittings: standard (British type-A/non-manipulative) and flare fittings (British type-B/manipulative). Standard fittings require no modifications to the tubing, while flare fittings require tubing modification with a special tool. Standard fittings are typically used for water, hydraulic, and compressed air connections, while flare fittings are used for gas and high-pressure lines.
When using compression fittings with flanges, there are several methods that can be employed. One method involves threading the compression fitting into the flange, and then securing the pipe into the fitting by tightening a nut on the other end. This type of fitting is known as a flareless compression fitting and is commonly used in hydraulic systems to create a leak-free connection.
Another method involves using a set screw coupler, which has threads on one side that can be threaded into the flange. The conduit or pipe is then inserted into the other end of the coupler and secured by tightening a set screw. This method provides a decent connection and is suitable for lightweight, non-structural projects.
To ensure the integrity of the compression fitting, it is important to avoid over-tightening the nut. Overtightening can compromise the joint and is the most common cause of leaks. Instead, it is recommended to tighten the nut first by hand and then use a wrench to tighten it further. The amount of tightening required varies with the size of the fitting. Testing and adjusting the fitting can help prevent leaks.

Using a pipe nipple and hammering a conduit on the other end
Mounting a pipe flange to an electrical conduit can be a challenging task. One method to do this is by using a pipe nipple and hammering a conduit on the other end.
A pipe nipple is a fitting commonly used in industrial pipeline connections. They come in various types, including common screw nipples, tubing nipples, and casing nipples. In this method, a galvanized steel pipe nipple is threaded into the flange, and a piece of conduit is hammered on the other end. This creates a secure connection.
To start, you will need to gather the necessary materials and tools, including a galvanized steel pipe nipple, an EMT conduit, a flange, and tools for hammering and threading. Ensure you have the appropriate size and type of pipe nipple and conduit for your specific application.
Next, you will need to thread the pipe nipple into the flange. This involves screwing the pipe nipple into the threaded portion of the flange until it is securely attached. Make sure the threads are aligned correctly and that the pipe nipple is tight and secure within the flange.
Once the pipe nipple is securely threaded into the flange, you can proceed to hammer the conduit on the other end. Place the conduit over the end of the pipe nipple and use a hammer to gently tap it into place. Ensure that the conduit is securely seated and does not move or wobble.
For added security, you can follow the method described by Aksel, a community member who shared a video on his YouTube channel. After hammering the conduit into place, drill through both the pipe and the nipple. Then, insert a bolt and secure it with a nut that runs through the drilled hole. This additional step will provide more stability and ensure that the connection is secure.

Using a threaded pipe insert to secure the pipe and flange
Firstly, you will need to source the correct flange for your project. Flanges are commonly available in either 1/2" or 3/4" threads and are typically made of cast iron, with black or silver colour options. These can be purchased at your local hardware store.
Once you have the flange, you can begin the process of securing it to the pipe. The first step is to thread the flange onto the pipe. This is done by twisting the flange onto the pipe, ensuring that the threads of the flange and pipe are aligned correctly.
Next, you will add a threaded pipe insert into the pipe. This is done by hammering the insert into the pipe until it is securely in place. The insert will add extra security to the connection by providing more surface area for the pipe and flange to grip onto.
After the insert is in place, you can further secure the connection by using a set screw coupler. One side of the coupler has threads that will twist into the flange, while the other side will hold the pipe in place. Tighten the set screw until the pipe is firmly secured.
Finally, you can add a fender washer and a countersunk bolt to the bottom of the flange for additional security. When you tighten the bolt, it will pull the conduit into the flange, creating a strong and secure connection.
