Our high-quality heat exchanger tubes are produced by cold drawing or cold rolling processes, ensuring excellent size tolerance and superior outside/inside surface roughness. Each tube is meticulously protected by end caps and PVC bags. For international shipping, we utilize reinforced steel angle bars for export packing to ensure the products remain well-protected during sea transportation.
