Construction and production of special forms of pipes and rebars with various alloys
Producing metal sections with standard non-geometric shapes and using engineering alloys requires deep metallurgical knowledge and advanced forming equipment. Many industrial parts cannot be made from ordinary market pipes and bars due to exposure to extreme stresses, high temperatures or corrosive environments. This is where the necessity of custom design and production of these products is revealed. In this specialized article, we examine the different aspects of the manufacturing process, alloy variety and standards in this field.
The importance of making and producing special forms of pipes and rebars with various alloys in the industry
Using this method brings several advantages, the most important of which are:
- Decreasing the final weight of the parts: By designing special sections, the material is distributed only in the sections that are under load.
- Reducing machining costs: By bringing the initial shape of the section closer to the final part (Near Net Shape), machining waste is minimized.
- Improving mechanical properties: Cold drawing and forming processes improve the granular structure and increase strength. They submit to metal.
The research and development department of Azer Gezhan, understanding this industrial need, has been able to equip its production lines to accept complex orders and produce parts with very precise tolerances.
The variety of alloys used in the production of pipes and special bars
Choosing the right material is the first and most important step in the process of making and producing special forms of pipes and rebars with various alloys. Depending on the working conditions of the part, different alloy groups are used, each of which has its own mechanical and chemical characteristics.
1. Carbon and low alloy steels
This category of steel is the most widely used material in general and construction purposes. By adding controlled amounts of elements such as chromium, manganese and molybdenum, the strength and toughness of these steels are improved. The cold drawing process on these alloys is easy to apply and provides a very good surface finish.
2. stainless steels
In environments where resistance to corrosion and oxidation is a priority, different grades of stainless steel (such as 304, 316 and 430) are used. The production of special forms with these alloys requires precise control of forming forces and specialized lubricants due to the high hardness rate.
3. Nickel base alloys and superalloys
In the oil, gas and power plant industries where the equipment works at very high temperatures and under a corrosive atmosphere, superalloys such as Inconel and Monel are used. The shaping of superalloy pipes and bars requires high technical knowledge and very resistant tools.
The industrial group Azer Tezhan, by mastering the metallurgical behavior of these various alloys, has made it possible to form parts with the highest metallurgical quality, so that the produced parts do not suffer premature failure or fatigue under hard working conditions.
New methods of forming and producing special metal sections
Production of non-standard sections requires advanced equipment and special methods. Cold drawing is one of the most efficient methods to achieve high dimensional accuracy and unique surface quality in the production of pipes and special bars.
Die and plug cold drawing process
In this method, the primary pipe or rebar is passed through the mold (Die) and on an internal hub (Plug). In addition to reducing the diameter and thickness of the wall, this process changes the shape of the outer and inner sections to the desired shape. Among the advantages of this method, the following can be mentioned:
- Achieving very precise dimensional tolerances (in microns)
- Improving the hardness and tensile strength of the material due to cold working
- Creating the quality of a mirror surface without pleats
Industries that require precise miniature parts or complex structural structures always choose the cold drawing process as an economical and high-quality option. Azer Traction company is the leader in providing these specialized services in the country by using modern Traction equipment.
Technical challenges in producing alloy parts with special forms
Although the construction and production of special forms of pipes and rebars with various alloys has countless advantages, but it is a very sensitive and challenging process. The smallest error in mold design calculations or alloy selection can lead to part destruction or severe tool wear.
Some of the most important technical challenges in this field are:
- Springback: After applying the forming force, the metal tends to return to its original state. Accurate calculation of spring return is critical in mold design. Inadequate lubrication: During cold drawing of hard alloys such as steel, a lot of heat is generated. Failure to use the proper lubricant will cause scratches on the surface of the piece.
- Microstructural cracks: Insisting on excessive reduction of the cross-sectional area in a stretching step creates severe residual stresses and leads to the creation of microscopic cracks in the texture of the alloy.
By performing detailed computer simulations before making the mold, the engineering team of Azer Gezhan predicts all the physical behaviors of the material and reduces the risk of production defects to zero.
Quality measurement criteria in the production of custom parts
Production line output of specific forms must be subjected to strict quality control protocols. Ensuring the structural health of parts guarantees their safe operation in large industrial equipment. Standard quality control methods include the following:
- Non-destructive testing (NDT): Using ultrasonic methods and magnetic particles to identify internal and surface cracks.
- Dimensional measurement with high accuracy: Using digital calipers, measuring projectors (shadow imager) and CMM devices to confirm tolerances.
- Mechanical tests: Tensile, hardness and impact tests to ensure the achievement of the target mechanical properties.
Customers of the industrial complex Azer Gezhan can be sure that all delivered products have successfully passed the multiple stages of quality testing and have a valid technical approval.
