After extrusion, the freshly formed copper pipes undergo an annealing process to relieve internal stresses and enhance ductility. Annealing ovens use controlled heating and cooling cycles, ensuring that the pipes are soft enough for bending and installation. Once annealed, the pipes proceed to the tubing stage, where they are cut to length and undergo quality inspections. Sophisticated laser cutting machines are often utilized for their accuracy and speed, minimizing waste and maximizing efficiency.
There are various types of rebar straighteners available, each designed to handle different sizes and conditions of rebar. Manual straighteners are often used for smaller jobs or specific, localized applications. They operate by manually pulling the rebar through a set of rollers that align it. While effective for certain tasks, manual straighteners can be labor-intensive and less efficient for larger operations.
