Answer: Carbon steel pipes are widely used in industries such as petrochemical, shipbuilding, aerospace, defense, construction, and mechanical manufacturing. They are mainly used for fluid and gas transportation, structural support, heat exchange, and heating systems.
Answer: The main advantages of carbon steel pipes include high strength, good pressure resistance, strong processability, and low cost. They also have good toughness and impact resistance, making them suitable for a variety of applications.
Answer: Carbon steel pipes have relatively poor corrosion resistance, especially in humid or marine environments. To improve their corrosion resistance, carbon steel pipes are often galvanized or coated, or suitable corrosion protection measures (such as painting or adding a protective layer) are used.
Answer: Common specifications for carbon steel pipes include outer diameters (OD) ranging from a few millimeters to several hundred millimeters, with various wall thicknesses (WT) available. Common standards include ASTM A106, ASTM A53, and DIN 17175. Different industries and applications may have different requirements.
Answer: The pressure capacity of carbon steel pipes depends on their specifications (outer diameter and wall thickness), material, and usage conditions. Generally, carbon steel pipes are suitable for medium-pressure applications (such as petrochemical pipelines, steam systems, etc.), but for extremely high-pressure situations, high-alloy steel pipes may be required.
Answer: Carbon steel pipes are suitable for medium to low-temperature environments. For high-temperature applications (such as boilers or heat exchangers), high-temperature carbon steel materials (e.g., low-alloy steel pipes) can be used. However, if the operating temperature exceeds the limits of carbon steel (typically between 300°C and 500°C), other materials such as stainless steel may be necessary.
Answer: Carbon steel pipes are generally not suitable for food and drinking water pipelines, especially if they are untreated. Due to the corrosive nature of carbon steel, improper use may lead to water contamination. If used for such pipelines, proper surface anti-corrosion treatment must be applied, or safer materials like stainless steel pipes should be chosen.
Answer: Carbon steel pipes are primarily composed of iron and a small amount of carbon, offering high strength and durability but poor corrosion resistance. In contrast, stainless steel pipes contain a higher proportion of chromium, providing stronger corrosion resistance, heat resistance, and overall durability, but they are more expensive. The choice of material depends on the operating environment and budget requirements.
