Q255/SM400 Welded steel pipe the billet used for welding steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding process. Because of its different welding forms are divided into straight seam welded pipe and spiral welded pipe two kinds. Because of the shape of its end, it is divided into circular welded pipes and special-shaped (square, flat, etc.) welded pipes.

API 5CT is the premier American Petroleum Institute (API) standard specification for steel casing and tubing used in oil and gas wells. It covers seamless and welded pipes for transporting oil/gas, protecting wellbores, and supporting structures. Key grades include J55, K55, N80, L80, C90, T95, P110, and Q125, chosen based on depth, pressure, and corrosive conditions.

FBE Coated Pipe, or Fusion Bonded Epoxy Coated Pipe, is a high-performance steel pipeline protected by a thermosetting epoxy coating applied through electrostatic spraying and high-temperature fusion. This coating forms a dense, firmly bonded layer that delivers outstanding corrosion resistance, electrical insulation, and adhesion, effectively preventing soil, moisture, and chemical erosion in buried or harsh service environments. Widely used in oil and gas transmission, water supply networks, and municipal pipelines, it ensures extended service life, high structural stability, and reliable long-term operation. Compliant with industrial standards, it is ideal for critical fluid transportation projects requiring durable anti-corrosion protection.

K9 Black Ductile Iron Pipe is a high-strength, corrosion-resistant pipeline product widely used in water supply and municipal engineering. Manufactured to strict international standards, the K9 grade ensures excellent mechanical properties, high pressure bearing capacity, and reliable toughness, effectively preventing cracks and breakages during installation and operation. With a black anti-corrosion surface treatment, it offers long service life and strong adaptability to various underground environments. Featuring good sealing performance and easy connection, it is widely applied in drinking water transmission, drainage networks, and urban infrastructure construction, providing safe and stable fluid transportation for long-term engineering use.

EN545/EN598 C25/C30/C40 Ductile Iron Pipe is a high-performance piping solution compliant with European standards, designed for water, sewage, and industrial applications. Featuring superior strength, corrosion resistance, and durability, it withstands high pressure (up to C40) and harsh environments. The pipe’s nodular graphite structure ensures impact resistance and long service life, minimizing maintenance costs. Ideal for municipal infrastructure, industrial plants, and irrigation systems, it guarantees reliability, safety, and cost-efficiency for global projects.

Spiral Welded Steel Pipe, also known as SSAW pipe, is fabricated by rolling steel strip coils into a cylindrical form at a fixed helical angle and welding the seam via submerged arc welding. This process enables cost-effective production of large-diameter, long-length pipes with excellent structural rigidity and pressure resistance. Widely applied in oil and gas transmission, water supply, sewage disposal, piling, and municipal engineering, it delivers stable performance and meets stringent industrial standards for fluid transport and structural support.
