S235J2 carbon steel pipe is a European standard non-alloy structural steel with excellent mechanical properties and weldability. It has a yield strength of ≥235 MPa, low carbon content (≤0.17%), and minimal phosphorus and sulfur impurities, offering superior resistance to atmospheric corrosion compared to ordinary carbon steel. It is widely used in building structures, mechanical manufacturing, and low-pressure fluid conveyance in ambient temperature environments, with an operating temperature range of -20°C to +300°C. Compliant with EN 10210 standards, common cross-sections include round/square shapes, with galvanized corrosion protection available for the surface.

10# Carbon Steel Pipe is a low-carbon steel pipe (0.07-0.13% C) with excellent plasticity and weldability. Commonly used in low-pressure fluid delivery, structural applications, and machinery parts. Complies with GB/T 8163 standard, offering good cold-working performance. Typical applications include water/gas systems and mechanical components. Equivalent to ASTM A53 Grade A.

Q195 carbon steel pipe is a low-carbon steel pipe with a low carbon content (approximately 0.06%-0.12%), featuring a yield strength ≥195 MPa. It exhibits good plasticity, weldability, and workability, and is typically manufactured as straight seam welded pipe or hot-rolled seamless pipe. Commonly used for low-pressure fluid conveyance (water, air) and simple support structures, it offers low cost and suits civil and light industrial applications with minimal strength requirements.

Carbon Steel Pipe is a versatile tubular product made from carbon-rich steel alloys, offering high strength and durability for structural and fluid transport applications. Available in seamless and welded types, common grades include ASTM A53 (general purpose), A106 (high-temperature), and API 5L (pipeline). Widely used in construction, oil/gas, and mechanical systems due to its cost-effectiveness and pressure resistance. 

S275 carbon steel pipes are a type of European standard structural steel with a yield strength of ≥275 MPa, offering superior mechanical properties compared to S235. With a carbon content of ≤0.21%, they exhibit excellent weldability and machinability, making them suitable for applications in building structures, mechanical manufacturing, and general engineering fields. Compliant with EN 10210 standards, it exhibits good weather resistance, with an operating temperature range of -20°C to +300°C. Common cross-sections include round and square shapes, with surfaces available in galvanized or painted finishes for corrosion protection.

‌Carbon steel square and rectangular pipe‌ is a square or rectangular pipe rolled from strip steel through process treatment. The specific production process includes unpacking, flattening, curling, and welding to form round tubes, then rolling the round tubes into square or rectangular tubes, and finally cutting them to the required length.
