Wire is sold in coils, and sometimes there are a lot of bent and twisted pieces lying around at home. But what to do if you need a piece - large or small - of perfectly straight wire? In industrial production, wire is straightened using special machines or using high temperatures. But what to do at home? FirstStroy.ru portal will tell you about simple and effective ways to straighten wire at home.
Home craftsmen have long come up with many ways to simply and cost-effectively straighten both wire from a coil and different pieces of wire - bent and twisted.
Method No. 1
We tie one end of the wire tightly to something strong - for example, to a concrete power pole. We unwind the coil to the required length, and wind the second end to a mobile object, for example, to a car tow bar, to a tractor, or to a winch.
Having started off the car, carefully tighten the wire. It is important to stretch it well, but not to tear it. Be careful, a wire that breaks like a string can seriously injure you or people nearby.
Typically this method is used when stretching wire with a diameter of 5 mm or more.
Leave the wire taut for 30-40 minutes, or an hour. Then the wire will “remember” the new shape and become straight, straighter than ever.
How to Straighten Copper Tube - Metalworker's Guide
HDPE pipe or low-density polyethylene pipe, or polyethylene system (PE) - basically they are all the same thing. The appearance of such products can be gray, black, black with blue stripes or blue.
The color does not affect the characteristics of the design, but traditionally elements of blue color and with blue stripes are intended for water (drinking).
When using such systems, frequently asked questions are: how to straighten a HDPE pipe, how to connect it, how to bend it, what to use it for, and so on.
HDPE pipes are used in pipeline systems with drinking and industrial water, and are also suitable for arranging a sewer system.
Pipes made of low-density polyethylene compare favorably with their characteristics compared to metal pipes.
Some of their advantages include the following indicators:
- light weight, and accordingly, transportation and installation will not require much effort;
- Just like a metal-plastic pipe, HDPE pipe is distinguished by its high resistance to corrosion, which makes it possible not to insulate the structure when laying in the ground;
- installation and connection are quite simple, especially with the use of compression fittings;
- no reaction with water, no metallic taste in drinking water, and no rust;
- due to its high elasticity properties, it is not damaged when water freezes inside the pipe;
- long service life;
- low cost.
Use of low pressure polyethylene pipes
This category of products is used in pipeline systems with drinking and process water, and is also suitable for arranging a sewer system. All pipes have appropriate markings that characterize the main parameters:
- purpose of the pipe (for drinking or industrial water);
- minimum strength;
- outer diameter size;
- wall thickness size;
- the value of the nominal operating pressure and other indicators.
HDPE pipes with a diametrical size not exceeding 180 mm are produced in coils tens of meters long. This quality is used to create long branches of pipeline systems without the use of connecting fittings. The ideal option for using HDPE pipes is considered to be external water supply, wiring in a summer cottage, connecting a pump to a well.
An example of using HDPE pipes in a water well.
By appearance it is very easy to identify a low-density polyethylene pipe intended for drinking water. The main thing is to pay attention to the thickness of the walls; it should be the same throughout the entire diameter. No foreign inclusions should be visible on the pipe section. Another important factor is the absence of any unpleasant odor.
Is it possible to connect a HDPE pipe in the same way as a metal-plastic one? The polyethylene pipe is connected using special fittings made of a material similar to the pipe material.
If you choose fittings by price, soldering fittings are considered the cheapest. Soldering methods can be different: either end-to-end or in a socket. This connection method is durable and strong.
More expensive fittings are collet or compression. They are also more convenient for installation.
The tightness of such a connection remains of high quality due to the presence of an o-ring, which is clamped with a special nut (clamping nut).
HDPE pipes: how to straighten them?
The question of the straightening method arises before everyone who has used HDPE pipes, since they are mainly sold in coils, respectively, in a curved form. Great physical effort is required to straighten the HDPE pipe.
Experts do not advise bending and straightening the part using your own knee and other parts of the body, as this can have a detrimental effect on health. You can use various available means, such as metal railings, brickwork, and so on. The smaller the segment of the straightened structure, the easier it is to straighten the part to the desired state.
There are also various devices for straightening HDPE pipes. As an example, we can give this option:
- a special trolley designed to perform the function of transporting and straightening pipes made of metal-plastic, polypropylene, polyethylene and other multi-layer pipeline fittings, the diameter of which varies from 14 to 20 mm.
Method No. 5
We make a hole in a wooden block with a diameter equal to the diameter of the wire (using a drill and an electric drill), strengthen the block in a vice, pass the wire into the hole, fasten the end of the electric drill chuck, and at low speeds, forcefully pull the wire through the hole.
In fact, there are a lot of ways to straighten wire at home, we just talked about the most effective and simple ones.

Method two: using a one-way tensioner
This method is relevant if you need to straighten twisted pieces that have already been used on the farm. Any strong and sufficiently stable object can be used as a tensioner. For example, I used a metal pipe that served as the base of the gate. You can find something more convenient. Then all the actions were performed according to this algorithm:
- I threaded the end of the wire through the pipe and moved it a distance so that alignment occurred along the entire length.
- I attached wooden blocks to both ends of the string to make the movements more convenient and painless. I strongly recommend not to ignore the creation of such handles, otherwise there is a very high risk of tearing or cutting the skin of your hands with sharp ends.
- I began to alternately tighten one side and then the other to the maximum range (as far as my hands can reach).
- Then he unscrewed the bars and cut off the uneven edges using metal scissors. The wire straightened out quite well.
If you need to align a wire of a certain length, then it is better to take it with a reserve, since the curved edges to which the handles are attached for convenience will have to be removed.
Advice! If the wire is old or rusty, then it is dangerous to align it in this way, since there is a risk that it will burst during tension and you will get injured.

Our production
Device for leveling steel wire with a diameter of 6-10 mm and strips 20x3 30-4 mm with a manual drive. Serves for straightening galvanized steel wire with a diameter of 6-10 mm, as well as galvanized steel strip measuring 20x3 mm, 30x4 mm. Round and flat conductors are supplied in coils of 40-50 kg.
In order to efficiently install an air-termination “mesh” made of steel wire on a flat roof, it is necessary to place the wire in holders and connect the nodes using terminals. The wire is laid in cells measuring 6x6 m, 10x10, 12x12 m. In order to lay the “mesh” conductor evenly, it must be straightened from its twisted state. Galvanized steel wire 8 and 10 mm is difficult to straighten manually, especially steel with a diameter of 10 mm, and in the straightened state there will be unevenness from uneven straightening.
To lay down conductors from lightning rods on the roof, chimneys and other structures of buildings and structures, and install conductors in holders, it is necessary to lay it as smoothly as possible without bending. The reason for this is the aesthetic appearance, as well as unevenness, as a result of which the wire may come loose from the holders or the holder mount itself may be damaged.
For ease of installation, our company offers this device for straightening conductors from nine rollers, which will allow you to save time on installing lightning rods, as well as install down conductors in the shortest possible time without fear of dismantling uneven sections of wire and strip.
The design of the wire straightening machine allows you to install it at a height of 0.5 m from the roof or floor on any structure made of wood or metal, adjust the pressure of the rollers on the conductor and achieve evenness of the wire or steel strip.
— installation on wooden pallets — 5 minutes;
- screwing screws into wood - 2 minutes;
— setting the pressure rollers for the conductor from 5 to 15 minutes;
— unwinding of a standard coil 115 m 5-7 minutes
— cutting to required lengths from 5 to 20 minutes
In total, on average, it takes up to 1 hour to unwind and prepare galvanized steel wire with a diameter of 8 mm for installation. For a building with a flat roof measuring 50x20 and 10 m high, approximately 3 coils of wire may be required, this means that in 3 hours you can prepare the conductor for laying on the roof and down conductors, without spending a working day on it.
How to Manually Align and Straighten Wire
In order to align a metal wire, it is necessary to expend not only some effort, but also use a number of simple devices.
Sometimes, for household needs or in the workshop, you need to use pieces of straight wire for work. But the question immediately arises: how to straighten the wire? After all, it is produced in factories and immediately packaged in round coils. This form is very convenient for storage and transportation. Therefore, in order to make a metal wire straight, it is necessary to expend not only some effort, but also use a number of simple devices.
Method three: creating and using a mobile machine
You need to build this one yourself. But I assure you that this will not take long at all and is as budget-friendly as possible. What I've done:
- I took a thick board (disassembled the old ladder);
- drove the nails strictly in a row so that the head protruded 2 cm from the board;
- then I just put a piece of wire between the nails and pulled it through.
The effect turned out to be quite good, and the string itself was now suitable for reuse.

How to straighten a wire: a homemade device
Sometimes neat wire rods of not very long length are required. How to align them quickly and perfectly without using a hammer? For such a case, there is a ready-made solution, which will be discussed in this video tutorial.
To make this homemade device, which will free you from the need to crumple the wire in your hands, trying to do the almost impossible, you will need a blank from a 70-gauge angle, three bearings and bolts with nuts for fastening the bearings. Two bearing units are installed stationary, and one can change position. This bearing is used to press the wire against two others during the pulling process. By changing the gap between the bearings, you can gradually narrow the space in which the wire will be located in this process.
How is alignment carried out?
A wire is inserted into the device, clamped in a vice, one end of which is clamped with a screwdriver. By pushing the rotating wire between the rollers and gradually clamping it between them, it is drawn and aligned.
