Threading on pipes – methods and tools

To keep your home comfortable and cut down on energy expenses, make sure your insulation and heating system are operating efficiently. The correct installation and upkeep of pipes—which transport hot water or steam for heating—is a crucial component of this. Knowing the different threading pipe techniques and tools is crucial whether you’re starting a new construction project or updating your current setup.

The process of threading pipes entails making threads or grooves all the way around the pipe to enable safe connections with fittings and other parts. This procedure is essential to guaranteeing your heating system operates without leaks and at peak efficiency. For threading pipes, there are various techniques and instruments available, each with unique benefits and uses.

Using a pipe threading machine is one typical technique for threading pipes. These devices, which thread pipes rapidly and effectively, are usually powered by electricity or pneumatics. For larger-scale projects or professional use, where accuracy and speed are crucial, they are perfect. Pipe threading machines are available in multiple sizes to suit a range of pipe diameters and materials.

A more affordable option for smaller-scale projects or infrequent use are manual pipe threading tools. These devices, which include ratcheting and handheld pipe threaders, enable users to manually thread pipes without the use of power sources. Manual tools are appropriate for do-it-yourself projects or minor repairs, even though they might take more time and effort than machine threading.

Utilizing threadless pipe connectors, such as press-fit or push-fit fittings, is another technique that is becoming more and more popular. These connectors use a mechanical or hydraulic mechanism to create a tight seal between pipes and fittings rather than threading pipes. They completely do away with the need for threading, but they might not work with all materials or applications.

Anyone working on insulation and heating projects needs to know the different tools and techniques for threading pipes. You can maintain the integrity and effectiveness of your heating system and, in turn, create a more comfortable and energy-efficient home by selecting the best technique and equipment for your particular requirements.

Types of threaded connections

It should be mentioned right away that you don’t need any particular abilities to carry out these tasks. However, being able to identify the kind of thread on the pipe is essential. For instance, it’s critical to discern between left and right knurling as well as between metric and inch knurling. Although there are many different types, inch and metric are the most commonly used.

The following are traits that set the inch and metric types apart.

Thread type in inches on the pipes:

  1. All elements are measured in inches.
  2. The presence of a profile in the shape of an isosceles triangle with an angle of 55 degrees at the top corner.
  3. Large pitch present. Consequently, this profile is larger and this type of threading is characterized by a higher strength.
  1. All elements are measured in millimeters.
  2. The profile is characterized by the shape of an equilateral triangle.
  3. A finer pitch.

When cutting rolled pipe for water pipes, use inch measurements; when cutting fasteners, use millimeter measurements.

We’ll talk about the different types of threads below.

  • Right. This is if the nut is screwed onto the bolt in a clockwise direction.
  • Left. The nut in this case is screwed in the opposite direction.

Only when the drill or rod volume used to create the hole is accurately chosen can the pipe be threaded to a high standard.

Expert advice: Choose a rod that is 0.003 cm smaller in volume than the external thread dimensions.

Individual parameters that define each thread on pipes are governed by GOST 621181.

Thus, the protrusion of the threads, for instance, is what defines a tapered thread in accordance with GOST requirements. These normative documents also define and cut with a groove. Additionally, as per GOST 621181, ascertain the cutting profile.

Required equipment

For cutting, only specialized tools are utilized. This is referred to as a pipe cutting set.

Typically, this set for pipes includes:

  1. pairs of dies or clubs used for processing pipe materials of different diameters;
  2. A holder that has a ratchet (although it can be without one). A club or die is inserted into it.

Some extra tools can also be used to complete such a set. These include clamps, pliers, and similar tools.

We will go into further detail about each of these tools later on.

Tools for manual machining – taps

The process of creating threads inside products involves threading with a pipe tap. The tools in this equipment range are shaped like screws. Chip grooves on a pipe are made with a tap. This tool has a shank that is fastened to a collar or machine. There are many different kinds, sizes, and quantities of taps.

A set, which consists of two taps, is used for cutting. The depth of cut distinguishes them from one another. For instance, the first number is used for roughing, and the second number is used for finishing.

The use of a die

Another name for cutting dies is lerks. In essence, this cutting tool is just a nut with holes drilled into it. They fashion the cuts’ edges.

Depending on how the cutting lerka is shaped, it can be:

  1. round;
  2. sliding;
  3. sliding;
  4. solid.

Any type of pipe product can be quickly prepared for connection with a tool like a lerka.

The pipe product’s end part and the die must be precisely perpendicular to one another. The possibility of the thread breaking or the thread diameter changing exists if a misalignment is permitted. Either way, the outcome won’t be satisfactory.

It is advised that all work be done smoothly, without jerks, with a lerka. The cutters and the thread’s surface area require periodic lubrication when using this instrument.

The die must be brought back up and the thread must be passed through once more after the last turn is finished.

Knowing the ins and outs of threading pipes is essential when it comes to heating and insulating your home. This article explores the many techniques and equipment for threading pipes, providing homeowners with a thorough how-to for this crucial home maintenance task. The smooth and effective operation of your home’s heating system can be ensured by having the appropriate tools and techniques, regardless of whether you’re taking on a do-it-yourself project or hiring a professional. We examine the available options, from conventional hand-threading techniques to contemporary power tools, and offer insights to help you make wise decisions for your home renovation requirements.

Using a club

A die for cutting threads is no more inefficient than a threading club. This is a more advanced and functional threading device. It consists of a slotted holder. They have replaceable cutters in them that are simple to swap out if they get blunted while working.

This threading device is unique in that it requires very little effort from the craftsman. It should be mentioned that using this device compared to other tools of a similar nature is far safer. This is due to the clapper holder’s internal guides, which significantly improve the device’s repeatable action accuracy.
