How to Connect Galvanized Pipe Without Threads

If you learn the type of coupling you use for galvanized pipe and the fitting procedure, you can ensure that it is leak-free.

Most significantly, this type of pipe comes with a rough or smooth zinc coating. However, the smoothness or toughness depends on the type of zinc and steel heating process.

The majority percent of the galvanized pipes are rough. That is why people find it difficult to seal the two pipes.

Things you need to do this:

1. A measuring tape

2. A Hackshaw

3. A putty knife

4. A wrench

Methods of threadless connections

All methods of connections that don’t require threads are divided into 2 large groups:

a) Welding Methods

Welding methods are classified into some subspecies. These are

1. Fusion welding

2. Pressure welding

B) Non-welding methods without threads

Non-welding methods are categorized into some subspecies like

1. Coupling using couplings

2. Connection using Gebo fitting

3. Flange connection

4. Tension connection

How you connect galvanized pipe without threads?

You might be worried about doing this job securely. Though it is a little bit tougher to set up properly, it’s not an impossible task to do so. Only some steps are to be followed. That’s it.

Step-1.

At the first step, you need to measure each pipe’s outer diameter that you use in your job. You can use tape to measure the pipe.

When the diameters match, then you should choose a standard coupling. On the other hand, if you find that the diameters don’t match, choose the stepped coupling.

Step-2.

To determine coating’s roughness and strength, you can examine the surface area of the galvanized pipe.

You need to choose a coupling that is manufactured to accommodate rough surface pipes if the galvanized coating is textured.

Step 3.

To check whether the pipe is square, the alignment of a carpenter’s level comes opposite to the non-threaded pipe’s end.

To get this job done, you can use a hacksaw or power saw to square each pipe when you find that the end is not flush. Release all the rough edges on the pipe end using a metal sander.

Step-4.

Dirt, greases, and other components can darken the coupling area. A cloth and a water-based degreaser are the perfect options to use to get all these things out. It will ease your work, and you can move much faster and perfectly.

Fix the middle pint of the coupling on the pipe joint, and you can use a pencil to mark the point at each coupling end.

Step-5.

Set an endpoint of the non-threaded galvanized pipe into the coupling. Set the coupling end with the drawn line on the pipe with an aligned mode.

Step-6.

At the last point, you need to tighten the fastening bolts until the coupling gets the galvanized pipes in the right place.

To do this job, you can use a torque wrench set at the coupling’s, which can mark torque requirement to fasten the bolts until the wrench gets off evenly.

Black vs. Galvanized Pipe Fittings

Black vs. Galvanized Pipe Fittings

The pipe market has seen the competition of two different types of pipes, and these are black steel pipe fittings and galvanized steel pipe fittings.

These two are the two most used pipes which are applied to transport liquid and gas. Both black steel pipe and galvanized pipes come with the building of steel. The galvanized pipe comes with a zinc coating; on the other hand, a black pipe does not.

Therefore, we can see that the galvanized pipe is more durable than the black pipe for transportation.

Due to the easy erosion of the black steel pipe, it is fit for carrying gas; on the other hand, galvanized pipe is a good option for carrying water.

Most importantly, We can see the usages of galvanized pipe to supply water to the home and commercial buildings.

Black steel pipe comes with seamlessness, making black steel a better type for gas transportation to industrial factories and big restaurants. This type of pipe prevents fire better compared to the galvanized pipe.

The main difference between the steel pipe and galvanized pipe is found on their surface. Black steel pipe is uncoated and comes without steam, and that is why it is widely used to transport gas like propane and natural gas to residential and commercial buildings.

Advantages of galvanized pipes:

Advantages of galvanized pipes

For the residential building, galvanized pipes are preferable to most of the house owners. It is coated with a layer of zinc, which prevents rust.

Most importantly, this pipe is so much strong and durable. For the transportation of water, this type of pipe is perfect.

Disadvantages of galvanized pipes:

Some people complain that this pipe’s life span is too short compared to other types of pipe. It lasts about 20-50 years.

Over time, mineral build-up inside galvanized pipes tends to get clogs that impede water’s regular flow.

Another negative character of this pipe is that it is very sturdy and heavy as well. Because of this, people find it difficult to work with.

When you find galvanized pipes damaged, the galvanization on the outside is compromised, and it leads the pipe vulnerable to corrosion in a small amount. Therefore, it is sometimes hard to use for users.

FAQ:

Galvanized Pipe

Question-1. Can galvanized pipes cause lead poisoning?

Answer: You can attach lead particles to the surface area of the galvanized pipes. Over time, the particles tend to mix with your drinking water, and it causes elevated lead levels.

Question-2. How long do galvanized water pipes last?

Answer: On average, galvanized water pipes last up to 50 years. However, the typical lifespan of this pipe varies. Sometimes, it could be 40 to 50 years.

Moreover, well-built, well-shaped galvanized pipes last more than the typical lifespan.

Conclusion:

The most important factor is that you need to use the galvanized pipe. When you connect two galvanized pipes without threads, you should go with the congenial steps for you. However, there are a lot of techniques and methods you can use. But remember the fact that you choose only the way you find easier.
