Ordinary carbon steel pipes are characterized by low carbon content, low strength, and good weldability. The main materials used in China factories are: Q195, Q215, Q235B, Q235D, 10#, 20#, and ASTM A53 Gr.B.

High-Carbon Steel Pipes manufacturers commonly offer 60#, 65#, 70#, and 65Mn spring steel, as well as tool steels T8, T10, and T12. Chinese factories exporting from these plants often use the American standard AISI 1065, 1070, and 1080 series. These pipes are characterized by high hardness, excellent wear resistance, and elasticity, and are widely used in elastic components, wear-resistant mechanical fittings, and tool-type pipe applications.

Lingchuang is a China manufacturer and supplier of seamless steel pipes and Carbon Steel Pipe Fittings, offering factory wholesale and OEM services for global buyers. The seamless carbon steel pipe features no welds, high strength, strong pressure resistance, and excellent sealing performance, making it suitable for high-pressure and high-temperature applications. With precise dimensions, stable quality, and long service life, Lingchuang products are widely used in fluid transportation, construction, and industrial pipeline systems.

China manufacturers of low-pressure carbon steel pipes offer a complete range of materials, covering commonly used national standards such as Q195, Q215, and Q235B/C/D; high-quality carbon structural steel 10# and 20#; and American standard ASTM A53 Gr.B and API 5L Gr.B suitable for overseas projects. Some manufacturers also offer Q355B low-alloy steel. These materials cover general structural applications, fluid transportation, and low-temperature environments, conforming to both domestic and international standards. They meet the needs of domestic municipal, water supply and drainage, and fire protection projects, as well as overseas low-pressure pipeline projects.

Carbon Steel Pipes factory employs a comprehensive quality control system: carefully selecting steel billets from leading steel mills such as Baowu and Hebei Iron & Steel, utilizing imported German forming equipment and a Lincoln automated welding system, achieving a welding qualification rate of over 99.9%. 100% ultrasonic testing, X-ray inspection, and hydrostatic testing (1.5 times the working pressure) ensure the absence of internal and external defects.

Pickled carbon steel coils use hot-rolled coils as the base material. After pickling to remove oxide scale and leveling, they offer excellent cost advantages and processing performance. The product surface is clean and smooth with low roughness, significantly improving coating and welding adhesion, making it suitable for direct use in high-end manufacturing.
