How to thread a pipe with a club
How to use the tool
After repeated use, simple rules should be followed:
- Replace worn parts in good time.
- It is mandatory to use lubricant when threading. It will facilitate the cutting process, provide cooling of the working surface, increasing the service life.
- Regularly free the surface from swarf. To do this, periodically make a rotation in the opposite direction to the slicing.
In case of breakdown of cutters it is always possible to purchase spare ones. True, when buying it is necessary to have their samples, so that they fit in the seats.
Buying a clipper is a good solution for repair work at home, as well as for professionals in the field of services to the public and organizations. Inexpensive, easy-to-use device allows high-quality restoration of old and installation of new pipelines.
How to thread a pipe: a detailed overview of the main methods
Do you like to perform home improvement works by your own hand, not involving various masters? Self-installation or repair not only saves money on calling in specialists, but also greatly increases self-esteem, because the right?
During the installation of utilities it is often necessary to prepare the threads on pipes. You have to find ways not to spoil the product.
We will tell you how to thread with different tools, which method is preferable to use in this or that situation. The article discusses ways that are available to unqualified performer. The features of threading different types of threads and equipment used in this.
The presented material is supplied with illustrative photo materials depicting the tools for carrying out the work. And the video with recommendations will help to understand in detail all the subtleties of this process.
How to thread a pipe.
With the help of these simple devices the thread is cut by hand, and only if it is impossible to use them, the help of a welder is used. Not because it is easier and simpler, no. It is more difficult to simply equip and deliver a welder to the site. Those are gas and acetylene cylinders, hoses, open flame again. I will not go into details here, today’s article is not about that.
We have the following situation: it is necessary to cut a steel pipe, and to assemble, say, the distribution of water throughout the apartment, from a modern material (no matter is it polypropylene, metal-plastic, or copper). For tightness we use a threaded connection, by means of an appropriate fitting. In principle, to thread the pipe problem, as already said read everyday, but I want to bring to your attention a dozen not insignificant moments. Not observing which, already without welding can not do.

Example of elements with threads
But the problem is that not always at the end of the pipe there is this thread. Here to create it is usually used a pipe threading cluppe hand threader.
In short, the principle of operation here is something like this:
- The end of the pipe is inserted into a special cylinder with cutters;
- then this cylinder starts to rotate;
- While rotating the tool blades act on the metal plane to make a thread in it.
Well, if in detail, there are a lot of nuances, about which it is very desirable to know before you buy a set of pipe tongs of different diameters. In this article, we’ll take a detailed look at such things, and also look at how to work with such a fixture. (See. also article Sewerage system: features.)
Carving to join parts has been known since ancient Egypt, and until the early 19th century, carving was done by forging and often the carving had to be refinished by hand. Matching a bolt-nut pair was not an easy task and the bolt and nut were held together until used in the mechanism. Modern technologies allow to produce hand carving tools of very high quality, and the result of cutting excludes accidents, leaks and prolongs the lifetime of the pipeline. Depending on the pressure in the pipeline you can use cylindrical pipe threads (BSPP) or conical pipe threads (BSPT). Handheld threading tools allow you to thread studs, bolts. punches, curves, bosses, etc.п. Manual threading tools, electric tongs or a threading machine may be used, depending on the diameter to be threaded and the amount of work to be done. Manual threading tool is justified in the absence of power in the area of works or limited working space. Ratchet or ratchet mechanism built into a hand clipper increases threading speed and makes this tool maximum comfortable to use. Ratchets are available as right-handed or left-handed. Manual tongs are most commonly used among hand held threading tools. In small diameters up to 2 inches, threading is done in one pass. 2 passes are sufficient for thread diameters from 2 to 4 inches. You can install both conical (BSPT) pipe combs (dies) and cylindrical (BSPP) and metric combs in the threaded head. Every type of thread can be produced with one size of pipe clamp. Reversible chasers are used for cutting pipe threads protruding from walls. To center the part in the threading tool, the heads can be fitted with a comb or guide shank for improved threading quality. REMS manufactures the REMS Eva manual ratchet threading tongs. Pipe thread diameters from 1/8″ to 2″ and bolt threads from 6 mm to 30 mm. Steel ratchet lever coated with plastic to prevent slipping in the hand. The direction of the clincher can easily be reversed. Quick-change heads can be inserted in and removed from the tool easily. Various sockets available for both manual and electric cluppers.
Tube and pipe threading: tools, techniques
Pipe threads are divided into five types, but the most popular options are conical and cylindrical. These variants of pipe threads are often encountered by householders. There are two methods for threading on the water pipe:
How to Thread Pipe EXTREMELY FAST
- automatic, involving the threading of water pipes with special machines and power tools.
- Manual. Special hand tools are used for this purpose.
If by duty a person needs to thread a large number of pipes, it is appropriate to buy a special power tool, which will facilitate manual labor.
When the need to obtain a threaded connection is an isolated case, then manual technology is suitable for such purposes. On water pipes, as well as pipes of heating systems, threading is carried out with a die.
The die is a steel disc, and its inner diameter has axial holes in varying numbers, which depends on the size of the product. The edges of these holes form the cutters with which the threading is carried out. to ensure reliability of such tools they are made of alloy steels or hard alloys.
Tap bits can be of various shapes (round, square, hexagonal or prismatic), but more often they are disk-shaped. Disc dies are used to make threaded joints on water pipes. To make it easy to work with the strip, they are additionally fitted with collars and screw fixation. Slotted dies also are available as solid, split, and adjustable.
One big disadvantage of single thread dies for threading pipes is quick chisel deterioration. This is due to the rigidity of the product’s own construction. Slotted or spring-loaded dies are of a less rigid design, which significantly increases tool life. Due to the spring mechanism, such a tool for threading pipes allows you to vary the diameter of the resulting threaded connections in the range from 0.1 to 0.3 mm. This type of device has a high resistance to tool wear, but is not able to ensure high accuracy.
Sliding dies are 2 working pieces intended for the setting into the clamping module. The ram with the special toolholding module forms a tool called a pipe clamp. Sliding dies are fixed in the tool using a sliding block and an adjusting screw. It is by means of the adjusting screw that the diameter of the thread is adjusted.
How to use the tool
Both the manual and electric models of the clipper are quite easy to use. There is a small, but obligatory set of rules for the performer of the work to ensure the quality of the thread, the comfort of the worker and the safety of the tool.
When threading with a crescent drill, considerable torsional and bending moments act on the pipe, therefore, the tool should be firmly attached to the pipe through the guide, additional fixation may be required for the pipe itself.
Quality of threading largely depends on the correct entry of cutters and, depending on the diameter and wall thickness of the pipe, a chamfer must be made on the end of the pipe using a file, angle grinder, bevel cutter or a hammer for this purpose. Just like other metal cutting tools, the klupp should be used with coolant. Threading with a cotter is much easier with used oil, grease or cleaning fluid.
Pipe tongs: purpose, types, features of threading
Although steel pipes have lost their leading position in the supply of cold and hot water, heating, are still widely used for the transportation of the same water and gas inside and outside homes, apartments. The basic method of mounting pipes by welding is not always available and can not be realized, often you have to use the threaded method of connection, using for threading a die or a modern pipe tongs.
What I do threading.
For threading a pipe with diameter 15 (aka 1/2, aka half an inch), I usually use a pipe lerk in the larko holder, which I put on the prepared cut of the pipe, the side that has facets, due to its length it serves as a guide, which is important for even engagement of the pipe lerk. I gently press the pipe with my hand and turn it clockwise with an adjustable wrench.
It is not always possible to use the guiding side, it happens due to the fact that the cut of the pipe for some reason made very close to the tapping into the riser, then you do entry with a hole. In this case you need to be more attentive, keep the hand perpendicular to the axis of the pipe, otherwise the thread can go crooked and the fourth turn will sell through the pipe. Actually if the chamfer removed throughout the diameter evenly, then the entry will go evenly, respectively, and all the thread.
You can also thread the pipe with a crescent, but usually a pipe of this diameter is used in patching, and it is not possible to use a screwdriver because of its bulk.
For the pipe with the diameter of 20 (aka 3/4, aka three-quarter inch), I thread with a tongs, though I have a three-quarter lumberjack in the lumberjack just in case. For the same reasons as in the paragraph above.
On a 25 pipe (aka 1, aka inch) and a 32 pipe (aka 1 1/4. I use a ratchet clamp (a.k.a. inch and a quarter), and only use ratchets. It is connected only with labor input of this work. Using cloppers the process is much simpler, easier and faster.
In the photo, in addition to the lathe and tongs with a screwdriver, presented that I use to tighten the thread connection, namely universal, sanitary sealant and sanitary flax. After the thread, apply sealant on it, trying to distribute evenly over all the coils, and then wind the flax, details about this tell (and show) in another article, the link will leave below.
Connections are not only threaded.
In my profession I have to connect polypropylene with cast iron, when installing sewers. Basically, this connection is made by means of the transition rubber sleeve that blotted with sealant is inserted into the bell of a cast-iron pipe or fitting, and already in it you insert the fitting blotted with sealant or a polypropylene pipe. It makes the connection airtight.
On the photo you can see kabolka of different thickness, it is also used for installation of drainage system by ramming it into the gap between the above described materials. Using bobbin is convenient because it can be dissolved and choose the strand of desired thickness. Relevant its use in cases where the transition sleeve does not fit the size, such cases are not frequent, but still occur.
