1. I found that the outer diameter of the pipe we needed was 0.2mm different from yours, is it possible to adjust the outer diameter?
Reply: Our compressed air pipe sizes comply with international standards. Because they are industrial products, there will be manual errors, but matching aluminum alloy pipe with our pipe fittings and sealing rings will not affect your use.
2. Which aluminum alloy you use?
Reply: Aluminum Profile NUS Alloy A96063 T5.
3. Which treatment has been applied to interior and exterior surface of your pipes?
Reply: The interior surface has been degreased, cleaned, and passivated, the exterior surface has been treated with resin powder spraying.
4. Which chemical product have been applied on the surface treatment?
Reply: Please contact us and we will send the relevant documents.
5. How many years is the warranty period for your products?
Reply: The compressed air pipeline engineering warranty period specified in Chinese National Standards is 2 years, the warranty period of our products is 10 years.
6. What's the replenishment policy we have to follow? Do we need to always buy by container or there is a MOQ?
Reply: If you need to customize colors or logos, a MOQ will be required. Otherwise, there is no other replenishment policy.
7. Could you please share us your HS code so that we can make sure of the Customs taxes?
Reply: Aluminum air pipe's HS code is 760820, the pipe fittings's HS code is 760900.
