Shield-Level Protection, Life Doubled ASTM A106 Coated Steel Pipe Φ323.9mm x 7.14mm (Sch 40) x 12m

1. Product Description

Coated Steel Pipes are composite pipes manufactured using high-quality carbon steel pipes as the base material, onto which one or multiple layers of high-performance anti-corrosion materials (such as epoxy resin, polyethylene, zinc, etc.) are applied to their inner and outer walls using advanced processes. They perfectly combine the high strength and rigidity of metal pipes with the exceptional corrosion resistance, wear resistance, and anti-fouling properties of the coating. This makes them an ideal solution for fluid transportation, structural support, and applications in harsh environments, significantly extending the service life of pipeline systems and reducing maintenance costs.

2. Key Product Parameters

• Base Pipe Standard: ASTM A53, API 5L, ASTM A106, EN 10210, GB/T 3091, GB/T 8163, etc.

4. Product Advantages

• Superior Corrosion Resistance: Effectively resists corrosion from atmosphere, soil, seawater, and various chemical media. Service life is 5-10 times that of ordinary steel pipes.

• Excellent Mechanical Strength: The steel base pipe provides extremely high resistance to pressure, impact, and deformation, ensuring safety and reliability.

• Low Fluid Resistance: The smooth inner wall coating has a low friction coefficient, enabling high transportation efficiency and reducing scale formation.

• Easy Installation: Compatible with various connection methods such as welding, flanging, and coupling, aligning with traditional steel pipe installation practices.

• Cost-Effective: Although the initial investment is slightly higher, the total life-cycle cost is low, eliminating the need for frequent replacement and maintenance.

• Environmentally Friendly & Sanitary: Complies with drinking water transportation standards (e.g., EP coating), non-toxic and odorless, ensuring the cleanliness of the conveyed medium.
