Product Description

Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. We manufacture steel pipe from a steel alloy containing nickel as well as chromium, which give stainless steel its corrosion-resistant properties. Stainless steel pipe resists oxidation, making it a low-maintenance solution that is suitable for high temperature and chemical applications. Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages, and pharmaceutical applications.

APPLICATION

Stainless steel has unique characteristics such as unique strength, high abrasion resistance, superior anti-corrosion performance and resistance to rust. Therefore, it is widely used in industry, food machinery, mechanical and electrical industry, household appliance industry, home decoration and finishing industry. The development prospect of stainless steel application will be more and more broad, but the development of stainless steel application largely depends on the development of its surface treatment technology.
