Product Description

1. Corten steel (Corten-A): GB4171-84 2. ND steel pipe (09CrCuSb: 09 chromium copper antimony): GB150-98 GB/T6728 
3. Spiral grooved pipe: GB3087-82 or refer to industry standard: DG1017-94 
Corten steel, also known as Corten steel, is divided into two categories: Corten A and Corten B, which are representative steels of the Cu-P series steel in the United States. They are low-alloy, high-strength, atmospheric corrosion-resistant structural steels and are called weathering steels in China.
 

Spiral groove tube

Spiral fluted tube, also known as spiral fluted tube, is an excellent double-sided enhanced heat exchange tube, which has a significant strengthening effect on the heat exchange process of single-phase fluid in the tube. Especially nowadays the problems of energy saving and environmental protection are becoming more and more prominent. How to improve the heat exchange efficiency of coaxial heat exchangers, reduce irreversible losses in the energy transfer process, and use energy more rationally and effectively has become a very important topic.
