7. Packing | *All of our nickel alloy seamless pipes and tubes are packaged according to international standards to prevent any possible damage or loss. By default, we will use thick woven plastic bags to bundle the finished pipes together in batches. For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements." | |
