The production of copper tee and copper elbow involves several steps: 1. Raw material sourcing: High-quality copper is sourced from suppliers and checked for purity and quality. 2. Cutting: The copper is cut into the required lengths for the tee and elbow using cutting machines. 3. Shaping: The copper is then shaped into the desired tee and elbow shapes using bending machines and molds. 4. Welding: The pieces are welded together using high-temperature welding techniques to ensure a strong and durable connection. 5. Polishing: The finished tee and elbow are polished to remove any imperfections and ensure a smooth surface finish. 6. Inspection: The finished products are inspected for quality control to ensure they meet industry standards and specifications. 7. Packaging: The tee and elbow are packaged and prepared for shipping to customers. Overall, the production process of copper tee and elbow involves precision cutting, shaping, welding, and polishing to create high-quality products for plumbing and HVAC applications.
