Carbon steel pipes are hollow tubular products made from carbon steel materials. They are like "robust metal conduits", primarily used for transporting water, gas, oil, steam, etc., or as structural support components. They are one of the most commonly used pipes in industrial and daily life scenarios. Core advantage
Strength sufficient, durable construction: The carbon steel itself has high hardness and compressive strength, and the pipeline can withstand certain pressure and external force impacts. It is unlikely to deform or break when buried underground or erected in the air, and has a long service life (typically 10 to 20 years in normal scenarios). 
High cost-effectiveness, cost-friendly: Compared to stainless steel pipes, carbon steel pipes have lower raw material costs and are more affordable. They are suitable for large-scale and long-distance use (such as urban water supply networks), significantly reducing the overall project cost. 
Flexible processing, strong adaptability: They can be processed into different diameters and wall thicknesses as per requirements, and can also be connected by welding, flange connection, etc., to adapt to various complex installation scenarios without being limited to fixed sizes. 
Compatible with common media, wide application: They are compatible with water, air, natural gas, and ordinary industrial steam, etc., without the need for additional complex anti-corrosion treatment. Daily use is convenient. 
Key parameters
Diameter (outer diameter / nominal diameter): Common range is DN15 (φ21.3mm) to DN2000 (φ2032mm), custom larger diameters are available for special scenarios; 
Wall thickness: For normal transportation, 3mm to 20mm; for high-pressure scenarios (such as steam pipes), it can reach 30mm or more; 
Material type: Commonly used Q235B (ordinary carbon steel, suitable for low-pressure, normal temperature scenarios), Q345B (high-strength carbon steel, suitable for medium-pressure, slightly higher temperature scenarios), API 5L X42~X80 (special carbon steel for oil and gas transportation, with stronger pressure resistance); 
Connection method: Welding (suitable for long-distance transportation, good sealing), flange connection (suitable for scenarios requiring disassembly and maintenance), threaded connection (small-diameter pipes, convenient installation); 
Surface treatment: Default black paint (no coating, suitable for dry environments), hot-dip galvanizing (anti-rust, suitable for humid, outdoor environments).
