Flexibility and ease of installation are the core advantages of our annealed TP2 copper fine bore straight pipe. This product undergoes a meticulous pit-type or tunnel annealing process to achieve the soft O60 state, allowing you to bend and shape the tube by hand without the risk of cracking or kinking. In complex refrigeration layouts, such as the internal piping of household refrigerators or wine coolers, our annealed TP2 copper fine bore straight pipe provides the versatility needed to navigate tight spaces. Despite its soft state, the material maintains its high-purity C12200 copper integrity (≥99.9%), ensuring excellent thermal conductivity and consistent throttling performance. We have optimized this tubing to reduce assembly time on production lines, as it is exceptionally easy to flare, weld, and connect to other refrigeration components.
As an established Tier-1 supplier to Guangdong Midea HVAC, we understand that "cleanliness is efficiency" in the refrigeration world. Each annealed TP2 copper fine bore straight pipe is produced on our specialized production lines where inner wall cleanliness is monitored at every milestone. We use high-precision cold drawing followed by controlled atmosphere annealing to ensure that no carbon residue or internal oxidation interferes with your refrigerant flow. Our factory's 15+ years of experience in the capillary tube market allow us to maintain a stable monthly capacity of 120 tons, ensuring that large-scale orders are delivered punctually. Choosing our annealed TP2 copper fine bore straight pipe means trusting a partner recognized as a Shaoxing City Enterprise R&D Center, dedicated to providing stable, eco-friendly components that meet both RoHS and REACH safety standards.
