Appearance difference: stainless steel pipe is usually finer than ordinary steel pipe and has a smooth surface, while ordinary steel pipe is thicker and has a relatively rough surface.

2️⃣ Difference in corrosion resistance: Stainless steel pipe has excellent corrosion resistance and is able to resist the erosion of a variety of chemicals, while ordinary steel pipe is prone to rust and corrosion.

3️⃣ Different materials: stainless steel pipe is usually made of stainless steel, while ordinary steel pipe is mainly composed of iron and a small amount of chromium, nickel and other metals.

4️⃣ Different strength: stainless steel pipe is usually stronger than ordinary steel pipe and has better mechanical properties.

5️⃣ Different Uses: Stainless steel pipe is mainly used in occasions that require high corrosion resistance, such as chemical industry, food and other fields, while ordinary steel pipe is mainly used in construction, bridges and other fields.

6️⃣ Different prices: stainless steel pipe is usually more expensive than ordinary steel pipe because of its manufacturing process and higher material costs.

In short, there are obvious differences between stainless steel pipe and ordinary steel pipe in terms of appearance, corrosion resistance, material, strength, use and price, etc. You need to choose the right pipe according to the actual use needs and occasions.
