Lingchuang is a China manufacturer and supplier of galvanized carbon steel pipes, offering DN15–DN600 sizes with outer diameters 21.3–630mm and wall thickness 2.0–12mm. Standard lengths include 6m and 12m, with OEM/customized sizes, non-standard diameters, and cut-to-length service available. As a factory-direct wholesale supplier, Lingchuang provides competitive price, stable quality, and global export support for industrial and construction procurement needs.

High-pressure carbon steel pipes are commonly made of high-quality carbon steel, low-alloy steel, and heat-resistant alloy steel. Chinese suppliers offer 20#, 45#, 16Mn (Q345B), 12CrMoG, and 15CrMoG. Exported to the US standard, they commonly use ASTM A106 Gr.B, Gr.C, and API 5L series, meeting the high-pressure fluid transportation needs under various pressure and high-temperature conditions.

Plastic-coated carbon steel pipes combine the structural strength of carbon steel with the corrosion resistance, cleanliness, and wear resistance of plastic coatings. They are acid and alkali resistant, do not scale, do not rust, and have a service life of up to 50 years, far exceeding galvanized pipes and ordinary carbon steel pipes. Applications cover multiple fields including public infrastructure, industrial production, and special projects. The processing of plastic-coated carbon steel pipes in Chinese factories requires multiple precision processes, with the core revolving around substrate treatment, coating adhesion, and curing.

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.
