Why Do You Need A Pipe Threading Machine?

With a pipe threading machine, especially an automatic one, you can increase your productivity of several operations related to pipes, such as cutting and threading.

To give you a better idea of this machine’s worth, you can go through the below-mentioned advantages:

• Symmetry – With an automatic pipe threading machine, you can quickly get a symmetrical custom design. Moreover, the string outlines on the pipes look cleaner.
• Productivity – Automatic pipe threaders have the efficiency to cut, thread, and ream pipes at a much faster rate than manual ones. That makes them more efficient for commercial purposes.
• Accuracy – These threading machines can create the most tedious threads accurately, and that too – on both ends of the pipe.
• Portable – These machines, both manual and automatic ones, can be carried around by just one person. The automatic ones might be heavier, but still portable.
• Simple to use – You do not have to learn many technical details to use these. That makes it more accessible and efficient to use.

How Does A Pipe Threading Machine Work?

Pipe threading machines are divided into two types – manual and automatic. Despite the classes, the fundamental technique implemented by a pipe threader is the same. The primary difference is the list of features.

To thread a pipe, you will first need to select the desired tube. To get a suitable length for the pipeline, you might have to cut it first. Most automatic pipe threading machines have this feature.

On the other hand, a manual pipe threader might not necessarily cut the pipe. Once the tube is cut as required, it can be placed in the vise jaw of the automatic threader.

If you are using a manual one, then you might need to lock the pipe in place using an external vise. Now, depending upon the diameter of the pipe, you will need to use the relevant threading die.

For the automatic threading machine, you need to switch on the motor to let the pipe be threaded to the desired length. Whereas, for the manual one, you need to use its ratchet-based mechanism to rotate the die over the pipe’s head.

The high-end ridges on the threading die apply pressure over the pipe’s end to create the threads efficiently. 

Things You Need To Consider When Buying a Pipe Threader

Whether you are threading a virgin material or repairing a damaged thread, there are certain factors to look into when purchasing a pipe threader. This will help you produce the best job with least extent of wear and tear on your tooling.

Threading is divided into two: internal and external. Internal threading requires a tool called TAP while external requires a DIE. Most projects require both tools applied to a given diameter of rod.

Also, consider the given pitch and size of threads you intend to cut. Both tap and dies may be used in cutting new or damaged threads.

Dies come in various materials and configurations. The most common is high speed steel for soft materials and cobalt for harder materials like stainless steel. Some materials may be coated to increase the cutting ability of the die making it easy for you.

Major Factors to Consider

1. Quality

When it comes to quality, you buy what you get. Cheap quality may cost you more. It is better to pay a little more to get a reliable tool. An economical set may be able to fill your present and future needs, saving you on money.

In order for the dies to cut, they ought to be harder than the material they are cutting. It is best you use a good quality tool to avoid breakage at all costs. The low quality ones may put stress on the tool while working on a project, causing it to go off center or break.

A threading machine is composed of units like a bed, apron and saddle. So, when purchasing the one that you require, it is important you ascertain that they are fabricated using materials that are of high quality to offer extended durability for reliability in the long run.

2. Thread Type

There are many different types available that are meant for different tasks. Hand threading dies are available in two types: round and hex die nuts. The Hex die nuts may be used with regular hand tools while round types are designed to fit into a T-handle

Hex die nuts are mostly used as chaser to repair existing threads while round dies are the best choice when it comes to cutting new threads. The hex die nuts do not require a handle to use while the round dies require a holder.

3. Thread Size

It is important for you to understand the size you need to get the job done. Standard thread sets are measured in threads per inch. There are two pitches for each diameter of threads. There are those tools that can thread a pipe to a given inch. Select one according to the requirements of your project.

Many of the tools will indicate the inches it will be able to thread, helping you to make the right choice. Also, you ought to know the required size drill bit for the hole you should drill. Using the ideal size hole is very crucial on two instances.

If the hole is too small, it may cause the tap to bind and even break as it cuts too much material. If the hole is excessively large, the root of the threads may be too shallow and insufficient, hence can strip out or fail.

4. Manual or Electrical

You have to consider whether you want the manual and electric types. The project to be completed determines the type of threader you should buy. Manual types are favorable for easy operations especially at home, workshop or other simple tasks.

The electric types come in handy for industrial and mining operations. For the electric types, ensure that the production speed per given hour is apt and the machine will not consume excess power than is actually required.

5. Other Considerations

Another aspect you ought to keep in mind when selecting a pipe threader is the features and difference of specifications it has. Make sure that the tool can be availed with varying threading capacities, spindle speed ranges and saddle movements.

Look for a machine that you can easily get spare parts for replacement. Instead of buying a new unit when the die wears off, all you have to do is replace. The guides and die should be interchangeable to save on cash. This also applies to other power tools you may have, including Best Electric Die Grinders.
