1. composition: stainless steel welded pipe is made of nickel chromium steel, carbon steel and iron, and has nickel, chromium, manganese, copper and other elements. The
ASTM A53 pipe, also known as the ASTM A53 pipeline, is used for mechanical and pressure applications, and also for general purposes of steam, water, gas and air pipelines.
2. corrosion resistance: the stainless steel tube has a good corrosion resistance because it contains two elements of chromium and nickel, and the two elements react with oxygen in the air to form an oxide film, thus protecting the pipe from corrosion. The ASTM A53 tube is very rusty.
3. use: the
stainless steel pipe can be processed on the surface, such as the mirror, the light surface, the drawing surface, etc., so the stainless steel tube is generally used for the decoration pipe, the supporting tube, the product tube, and the industry can be used in industry, but ASTM A53 is mainly used in the oil and gas industry.
4. price: the price of stainless steel welded pipe is higher than that of ASTM A53 pipe.
