Main Types of Steel Pipes:
Black Steel Pipe: No protective coating, rust-resistant, strong enough for high-pressure fluids like natural gas or oil.
Galvanized Steel Pipe: Coated with zinc to resist rust, commonly used for clean water pipes and water distribution.
Stainless Steel Pipe: An alloy of iron, chromium, and nickel, highly corrosion-resistant, ideal for chemical plants or seawater.
Seamless Pipe: Without welds or joints, very strong, suitable for high-pressure applications (oil and gas).
Welded Pipe: Made from bent and welded steel plate, the opposite of seamless.
Hollow Pipe: Square or rectangular in shape, often used for building frames, fences, and canopies.
Oval Pipe: Oval in shape, used for interior design, automotive applications (exhaust pipes), or furniture (table/chair legs).
Ductile Pipe: Modified cast pipe, stronger and more flexible, used for water and drainage.
