1. Composition: Stainless steel welded pipe is composed of nickel-chromium steel, carbon and iron elements, including nickel, chromium, manganese, copper and other elements. The ASTM A53 pipeline, also known as the ASTM A53 pipeline, is used for mechanical and pressure applications, as well as for general purposes of steam, water, gas and air pipelines.


2. Corrosion resistance: Stainless steel pipes have good corrosion resistance because they contain two elements, chromium and nickel, which react with oxygen in the air to form oxide film to protect the pipes from corrosion. ASTM A53 pipeline is very rusty.


3. Usage: Stainless steel pipe surface can be processed in various ways, such as mirror, smooth surface, wire drawing surface, etc. So stainless steel pipe is generally used for decoration pipe, support pipe, product pipe, industry can be used for industry, but ASTM A53 is mainly used for oil and gas industry.


Price: Stainless steel welded pipe is more expensive than ASTM A53 pipe.
