Publish Time: 2024-09-12
The Second Hand ERW High Frequency Pipe Making Machine is a key equipment for manufacturing high-quality welded pipes. By heating the edges of metal pipes with high-frequency current and then welding these edges together with pressure, the Second Hand ERW High Frequency Pipe Making Machine can produce high-quality pipes of various specifications and uses.
1. Precise control of high-frequency current
High-frequency heating: The ERW pipe making machine uses high-frequency current to heat the edges of metal pipes to the temperature required for welding. The frequency and intensity of the current must be precisely controlled to ensure uniform heating and avoid overheating or insufficient heating to ensure welding quality.
Heating uniformity: Uniform heating ensures that the edges of the pipes are well fused during the welding process, thereby producing welded pipes with consistent strength. High-frequency pipe making machines are usually equipped with advanced heating control systems to ensure the uniformity of the heating process.
2. Control of welding pressure
Welding pressure: The pressure applied during welding is critical to the quality of the pipe. Too high or too low pressure can cause welding defects. Second Hand ERW High Frequency Pipe Making Machine ensures the stability of welding pressure through a precise pressure control system to achieve high-quality welds.
Pressure balance: The balance of welding pressure affects the integrity and strength of the weld. Accurate pressure control can reduce weld defects, such as incomplete fusion of the weld or the presence of pores.
3. Material selection and processing
High-quality raw materials: The premise of producing high-quality pipes is to use high-quality raw materials. ERW pipe making machines are suitable for a variety of metal materials, including carbon steel, stainless steel, etc. The chemical composition and physical properties of the material directly affect the final quality of the pipe.
Material pretreatment: The pretreatment of materials (such as descaling and surface cleaning) is very important to ensure welding quality. ERW pipe making machines are usually equipped with a material pretreatment system to remove the oxide layer and contaminants on the surface of the material.
4. Design of welding head
Welding head configuration: The design and configuration of the welding head have an important impact on the welding quality. The welding head of Second Hand ERW High Frequency Pipe Making Machine usually adopts advanced design to ensure stability and efficiency during the welding process.
Maintenance of welding heads: Regular maintenance and replacement of welding heads are key to ensuring the quality of pipes. Worn or damaged welding heads may cause uneven welds or other defects.
5. Cooling system
Post-welding cooling: The pipes after welding need to be cooled by the cooling system to stabilize the structure of the weld and the metal. Temperature control during the cooling process is essential to prevent weld deformation and maintain the mechanical properties of the pipe.
Cooling uniformity: Uniform cooling can reduce the stress generated during welding and prevent cracks or deformation of the pipe. Second Hand ERW High Frequency Pipe Making Machine is equipped with an efficient cooling system to ensure the stability and uniformity of the pipe.
6. Automation and control system
Automation control: Modern Second Hand ERW High Frequency Pipe Making Machine is equipped with advanced automation control systems that can monitor and adjust production parameters such as current, pressure, temperature, etc. in real time. These automation systems improve production efficiency and consistency of pipes.
Quality inspection: The automation system usually integrates online quality inspection functions, which can monitor key indicators such as pipe size and weld quality in real time to ensure that each pipe meets the standards.
7. Post-processing process
Surface treatment: After welding, the pipe usually needs to be surface treated to remove oxides and impurities generated during the welding process. Surface treatment processes include pickling, galvanizing, etc., which are designed to improve the corrosion resistance and appearance of the pipe.
Sizing: The post-processing process can adjust the size of the pipe to ensure that it meets the requirements of use. Including process steps such as cutting and straightening of the pipe.
Second Hand ERW High Frequency Pipe Making Machine is able to produce high-quality welded pipes by precisely controlling high-frequency current, welding pressure, material handling, welding head design, cooling system, automatic control and post-processing processes. The meticulous management and efficient execution of each link are the key factors in casting high-quality pipes. These factors work together to ensure that the pipe has excellent mechanical properties, surface quality and dimensional stability to meet the needs of various industrial applications.
