Steel pipes are pipes made of steel. Common materials include carbon steel, alloy steel and stainless steel. Processes for manufacturing steel pipes include seamless, welded and spiral seam. Seamless steel pipes are manufactured by heating and stretching steel billets and have high strength and sealing properties. Welded steel pipes are made by connecting steel plates through a welding process. The common ones are long welding and spiral welding. Spiral welded steel pipes are usually used to transport liquids and gases, while long welded steel pipes are suitable for high pressure, high temperature and special environments.
1. High strength: Steel pipes have high strength and rigidity and can withstand greater pressure and load.2. Good corrosion resistance: Stainless steel pipes have excellent corrosion resistance and are suitable for situations involving chemical substances or humid environments.3. Strong adaptability: Steel pipes can be cut, welded and connected as needed, making them easy to install and use.4. Wide application: Steel pipes are widely used in building structures, petrochemical industry, water supply and gas supply, HVAC, shipbuilding and other fields.| Grade | Ni | Mn | P | C | S | Si | Cr | Mo | N | |
