Deformation of profile pipes
Profile pipes are divided into these types according to the available section:
- Round.
- Square.
- Polygon.
- Rectangle.
A seamless products are created by hot and cold welding.
Plants for the manufacture of products make their production by deformation of products of round sections. So the strips are made with a cross-section on the steel billet, it delivers in the form of rolls, which are cut to the desired size. The circular cross section appears after the workpiece passes through the forming device.
The production of the profile pipe is made, both in the cold and hot state of the metal. Then the products are welded in a protective gas environment, but to make the joint strong, the rolls squeeze it. The metal layer that was formed during the welding process is removed with a tool.
The products are then cooled with an emulsion and placed in the forming rolls due to the pressure to impart the desired profile.
The weld quality is then checked during an eddy current defect inspection. The equipment operates in such a way that, with the help of the magnetic properties of the metal and its effect on the chemical composition of the weld, and compare them, while at the same time determining physical defects.
The final stage of work with products is cutting of measuring pieces and determining the full cycle line, that is, thermal preparation. Processing takes place gradually by heating the workpieces and removing deformations. After the product cools down, the quality of the product increases severalfold.
Your attention was given to a typical process of manufacturing a profile pipe in a large factory.
Profile pipes of electric welded type
To reduce the cost of production, most manufacturers use technology to deform the product.
Production of the profile pipe takes place in such stages:
- Place the cut slice into the forming mill. To give the pipe the required profile, use the form of rollers.
- The product is laid in the welding machine and the full cycle lines are processed.
- Heat treatment is required at each stage, in particular this can reduce the product's own price.
Deformation of pipes in cold state
It is noteworthy that cold production of pipes often occurs in a small enterprise where it is required to make a round section of the finished product. For the company they install small equipment with a small capacity, but it is enough to meet the needs of small and large customers.
The only disadvantage of these enterprises is that it will be impossible to prepare a profile pipe of super-strong level on this equipment. In this case, it is worthwhile to involve a large industrial enterprise, and for decorative details it is possible to use the services of a small factory.
How to choose the equipment and production depending on their features?
When the production of a profile pipe needs to be made in the near future, it is worthwhile to determine the desired degree of quality for the products.
And before choosing production and equipment, you need to buy medium power machines and determine the working area. It is important to choose equipment, and it is more often divided into such devices:
- welding line( automatic);
- machine for bending profiles;
- machine for forming round shapes for workpieces;
- pipe cutter.
It is worth remembering that at every stage control is needed. And it is important to make thermal treatment of products, which, although it increases the cost of goods, but improves the quality. Compensate for the money spent by selling and large volumes of production.
Scope of profile pipes
The main purposes for the application of the pipe:
- For the preparation of decorative devices for various applications( but for them it will be necessary to purchase grinding equipment to ensure reliability and quality).
- For the manufacture of furniture elements.
- For installation and creation of various light installations, for example, kiosks, tents, greenhouses, skeletons and other simple buildings.
- Installation of more complex buildings requiring high reliability and durability. Requires purchase of full cycle products.
On the basis of the above, it is important to note that profiled pipes are almost universal material, the only thing is that it should not be used for water supply, but for any other purposes as you like.
