Profile pipes often become the material for the manufacture of various crafts for the garden, in particular - they are used to make arches. The attractive sides of this material are the low weight of the product, the ability to apply paint to the surface of the pipes, if necessary, to restore color or the desire to give the product a bright shade.

How can I use an arch from a profile pipe

Note that the field of application of metal core products does not quite coincide with their immediate purpose; pipelines for transferring gas or liquid are rarely collected from them. Most often, they serve as material for the assembly of lightweight building structures, in particular - quickly erected structures. A positive characteristic of pipe products of this type is the increased strength obtained due to the presence of additional stiffening ribs.

Among the undoubted advantages can be called light weight, which allows to minimize the load on the foundation or supports, to reduce risks in the construction of load-bearing structural elements. If the structures have rectangular shapes, then the installation work does not cause any difficulties. The question is completely different if arches from a profile pipe are required. Here it is very difficult to do without special knowledge, skills and tools.

Of course, if you wish, you can use the services provided by specialized companies and order the execution of bends on shaped pipes or tubular products of a round shape. But if you wish, you can try to do this complex work yourself.

Features of arched structures

Often, the improvement of the site involves the construction of several useful objects for the economy:

• garages and greenhouses,
• arbors and canopies,
• tables, benches,
• temporary houses and fences.

It will look picturesque against the background of lush green pergola or just an arch from a plastic pipe, making it not so difficult with your own hands.

Profile plastic pipes are commercially available in a wide range, with different cross-sections, their assembly is easy.

If you use profile pipes when creating the frames of the above-mentioned structures, the installation process can be significantly simplified and accelerated. But again, the question arises of using bent elements. In addition to providing attractiveness and visual lightness to structures, they are also able to reduce wind loads on the structure. If we are talking about the winter period, then it should be remembered that snow masses do not accumulate on the arc-shaped roof.

Calculation of the arch from the profile pipe can be performed using a special program or using the on-line calculator, in order to get an accurate result, you need to set the length and height of the chord. As a result of the calculations, the profile deflection depth will be determined, which will need to be obtained as a result of processing the pipe with a manual hydraulic pipe bender or bending machine.

What are the requirements for pipe structures

In order for the construction process to end with the creation of a solid and reliable structure, the following rules should be remembered, which have a close relationship:

1. To create an arched structure, pipes of suitable diameter should be used.
2. Bent products should not have fractures, waves, or other defects on the surface. The beautiful appearance of the product largely depends on the correct geometry of the arches included in its design.
3. If the used bent profiles in the structure of the structure are not exactly the same, then ultimately this fact can lead to a skew of the structure, i.e. the possibility of using multi-dimensional products in one design should be excluded.

Arc manufacturing options

Experts call into question the possibility of a high-quality task with a manual pipe bender. Difficulties with obtaining a satisfactory result usually arise due to the fact that the pipe bender, although it is a special device, is designed to give a certain shape to pipes with short and small diameters.

Making an arc using a manual pipe bender, watch a video:

The chance to give the same shape to several high arches on such a device is negligible. Of course, craftsmen can achieve good results, but it will be too difficult for an inexperienced worker to cope with such a task, but gaining experience in such a process does not make much sense - an arch from a pipe with your own hands can be made in another, simpler way.

For example, you can bend the pipe with trimming. The main drawback of this embodiment of the manufacture of the arch is the inaccurate appearance, the method with subsequent welding can be used if the aesthetics of the product will not be of particular importance.

Profile Bending Machine

Pipe bending machines are specialized industrial equipment, their use cannot be called justified if the work is performed one-time and its volumes are far from large-scale. Naturally, in the conditions of a summer cottage, the use of such equipment will look at least ridiculous.

The second important point is that it is simply irrational to fulfill single orders on such equipment, because for the manufacture of each single product it will be necessary to make a fairly complicated machine setup. Typically, the result of such processing are arches with an insufficiently accurate profile and side planes deployed by the propeller.

If the scope of work is large enough, it is easier to order the manufacture of arches on a bending machine for a profile pipe in a specialized company.

How to make an arch from a profile pipe with your own hands

Of course, the methods that will be discussed further will not cause either interest or appreciation from specialists working on the manufacture of numerous structures.

Nevertheless, it is these good old ways that will help home craftsmen make several correct arches and build from them a support for growing curly ornamental plants, a greenhouse, and a house canopy.

We make arches according to the pattern

The first advantage of the method is the absence of a threat of damage to the bent pipe. They begin work by drawing the calculated contour on a thick sheet of metal, in full size. Then, along the drawn line, sections of the profile are welded vertically, the height of these fragments must exceed the size of the pipe section by at least 4 or 5 cm.The step of arranging the sections of the profile should be about five centimeters.

Instead of a metal sheet, a concrete slab can be used to make a template, it will require making the necessary number of holes and fixing strong metal rods with a diameter of about 12-14 mm in them. This design can also be used as a template the required number of times.

To securely fix the end of the arch, you will need at least 3 or 4 securely fixed pins. Experienced craftsmen advise welding the end of the profile pipe to the rod.

You can bend the pipe manually, work should be done slowly, carefully, with sudden movements, the product may break. To reduce the applied physical effort, you can use a winch or lever. It is possible to bend a high-quality arc in this way if it has a small cross section.

We make an arch, use a grinder and a welding machine

This method of manufacturing the arch is suitable if the structure of the pipe is hidden behind the finishing material - any welding seam, even if it is performed by the master, will be noticeable on the finished product. Careful grinding will not hide it either.

The work is performed in the following order:

• on the pipe mark the segment on which the bend will be performed,
• cuts are performed at regular intervals in the marked section, leaving only the outer section of the wall intact,
• the sawn profile pipe is bent at the desired radius, it is very simple to do,
• weld places and carefully grind.

A hot method of manufacturing an arch from a profile pipe

To use this method, you need to stock up on clean sand. One end of the pipe is hammered with a peg, the other is filled with sand, as long as it fits. Then close the second end. For this method of manufacturing the arch, you will also need a template or blank of calculated radius. Having outlined the area on which the bend will be performed, they begin to heat it with a blowtorch.

Then, using the template, bend the pipe. A pipe filled with sand is guaranteed not to burst, deformations during its bending will be minimal. Then plugs are burned out, and sand is poured out of the pipe.

Watch a video on how to bend a pipe:

Using the above-described simple devices will help to independently bend arches from profile and round pipes, build small original buildings on the site with your own hands, without involving specialists in the work.
