Difference between Stainless Steel Welded Pipe and ASTM A53 Pipe

1. Composition: Stainless steel welded pipe is a nickel-chromium steel, carbon and iron elements out, there are nickel, chromium, manganese, copper and other elements. ASTM A53 pipe, also known as ASTM A53 pipe, is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. 

2. Corrosion resistance: Stainless steel tube because it contains two elements of chromium and nickel, these two elements and oxygen in the air chemical reaction occurs to form an oxide film, which protect the pipe is not corroded, so the stainless steel tube has a good corrosion resistance. ASTM A53 pipe is very rusty.

3. Uses: Stainless steel tube surface can be a variety of processing, like can be made of mirror, glossy, drawing surface, etc., so stainless steel pipe is generally used for decorative pipe, prop tube, product pipe, industry can be used for industrial, but astm a53 is mainly used in oil and gas industry.

4. Price: The price of stainless steel welded pipe is more expensive than ASTM A53 pipe.
