The importance of industrial pipes with custom dimensions
Why do we need to convert all types of pipes with custom internal and external diameters in Tabriz?
cold drawing process; The golden key to custom conversion of pipes
In this method, the tube is passed through special molds called Die to reduce its outer diameter. At the same time, a mandrel is used inside the tube to accurately adjust the inner diameter and wall thickness. Passing the pipe through these two tools by applying strong tensile force causes plastic deformation of the steel at ambient temperature. The result of this process is a pipe with completely customized dimensions, a highly polished surface and improved mechanical properties that exactly match the customer's needs.
Technical advantages of custom cooled draw tubes
Using the conversion services of various types of pipes with custom internal and external diameters in Tabriz provided by Azar Traction Company brings many technical and economic benefits for industries:
- Extremely high dimensional accuracy: The dimensional tolerance in the cold drawing method is so low that the resulting pipes can be used in hydraulic and pneumatic systems without the need for secondary machining.
- Improved surface smoothness: The roughness of the internal and external surfaces is greatly reduced, which minimizes friction in moving parts.
- Increasing yield strength and tensile: The hardening process during cold drawing causes the crystal structure of the metal to become more compact and the mechanical resistance of the tube increases.
- The possibility of producing thin-walled tubes: Tubes with very small thicknesses, which are impossible to produce by hot rolling, are easily produced in this process.
Wide applications of customized pipes in various industries
A major part of the demand for converting all types of pipes with custom internal and external diameters in Tabriz belongs to the country's strategic industries. Some of the most important of these applications are:
- Automotive industry: Manufacturing of axles, shock absorbers, steering rods and axles that require light pipes with high strength and precise dimensions.
- Hydraulic and pneumatic industry: Production of hydraulic cylinders and jacks in which the inner diameter of the pipe must be completely smooth and without tolerance in order to seal properly.
- Machinery and equipment Industrial: Manufacture of hollow shafts, industrial rollers and rotating parts of heavy machinery.
- Oil, gas and petrochemical industries: Use in special heat exchangers and material transfer systems that require unusual wall thickness to withstand high pressures.
The role of Azar Trakshan Company in the localization of industries
With years of brilliant experience in the field of steel cold drawing, Azar Stretching Company has been able to fill the void in the supply of precise industrial parts. Relying on engineering knowledge and advanced equipment, this complex has made it possible to convert all types of pipes with custom internal and external diameters in Tabriz with world-class standards.
Collaboration with Azar Trakshan Company gives manufacturing industries the possibility to break their dependence on the import of precise European and Asian pipes and to supply the parts they need in the country with a competitive price and a quality equal to foreign samples. The precise design of the custom die and mandrels in this collection has made there is practically no limit in the production of custom diameters.
The stages of designing and producing customized pipes in Azar Trakshan Company
To convert various types of pipes with custom internal and external diameters in Tabriz, strict engineering and monitoring procedures are carried out so that the final product reaches the customer without the slightest deviation. These steps are as follows in the Azar Traction company:
1. Examining the engineering plan and measuring the dimensional requirements
In the first step, the technical experts of Azar Traction company check the exact dimensions required by the customer, including the outer diameter, inner diameter, wall thickness and base alloy material. At this stage, the allowed tolerance and the final use of the pipe are determined.
2. Selection of raw pipe suitable for the final product
A suitable raw pipe should have dimensions close to the final parts so that it does not suffer from tearing or structural instability during the conversion process. The correct choice of the raw material has a direct role in the quality of the final product.
3. Design and manufacture of special tools (die and mandrel)
Due to the customization of the dimensions, the tension molds and internal mandrels are specially designed and produced using hardened tool steels to resist wear.
4. Surface preparation and lubrication of pipes
The pipes must be acid washed and phosphatized before stretching so that any oxide scale is removed from them and the lubricant layer sits on the surface of the pipe. This prevents the metal from sticking to the mold.
5. Carrying out cold stretching and stress relief operations
The pipe is passed through the mold with controlled speed and force. After the stretching process is completed, stress relief heat treatment is applied to the pipes to improve flexibility and remove residual stresses caused by cold deformation.
