Production Process of 6061 Aluminum Large Forged Pipe with Grooved Ends
According to the customer's requirements, our company successfully manufactured a high-strength 6061 aluminum large forged pipe and carried out precise grooving at both ends of the product. This ensured the product met the application requirements and exhibited excellent performance.

Production Process
1. Material Selection and Preparation
6061 aluminum alloy was selected as the raw material due to the following characteristics:
●High Strength: Suitable for structural components that bear significant loads.
●Excellent Corrosion Resistance: Ideal for use in diverse environments.
●Outstanding Machinability: Ensures precision during subsequent processing and grooving.
During material preparation, strict inspections were conducted on the chemical composition and metallurgical quality of the billet to ensure it fully met production requirements.

2. Fabrication of the Large Forged Pipe
We used advanced forging technology to manufacture the 6061 aluminum large forged pipe. The key steps are as follows:
●Heating: The billet was heated to the optimal forging temperature range for 6061 alloy, ensuring the metal was in the best plastic state.
●Forging and Forming:
●Using a high-tonnage hydraulic press, the billet was gradually expanded and forged into a large pipe shape.
●Pressure, deformation rate, and temperature were strictly controlled during the process to ensure uniform grain distribution.
●Heat Treatment: The pipe underwent solution treatment and artificial aging to enhance its strength and toughness, achieving the T6 temper.
●Dimensional Accuracy Control: The diameter, thickness, and length of the pipe were measured and adjusted multiple times to ensure full compliance with customer specifications.

3. Grooving at Both Ends
After the forged pipe was fabricated, precise grooving was performed on both ends of the product.
●Precision Grooving: Multi-tool cutting was employed to gradually create smooth and dimensionally accurate grooves.
●Dimensional and Quality Inspection:
●High-precision measuring tools were used to check the depth, width, and position of the grooves to ensure all parameters met customer requirements.
●The grooved surfaces were inspected to ensure smooth edges without burrs or cracks.

Advantages of the Process
●Combination of High Strength and Precision: The T6 temper heat treatment enhances material performance, while the grooving process ensures exceptional accuracy.
●Seamless Integration: The forged pipe and grooving processes are perfectly integrated, reducing errors from separate part processing.
●Reliability and Consistency: Every step followed strict process control, ensuring that each product meets customer expectations.

Conclusion
Through meticulous process control and precise grooving technology, we successfully completed the fabrication and processing of the 6061 aluminum large forged pipe. The product met customer expectations in terms of strength, dimensional accuracy, and groove quality. This achievement highlights our technical expertise and service capability in the field of high-performance aluminum products manufacturing.
