Product Description

Tianjin Juming Steel produces Dual Layer External Coating Pipes for municipal and overseas gas infrastructure. Made from high-quality carbon steel, the pipes feature inner and outer flame-retardant, anti-static FBE epoxy coating. Pipes provide corrosion resistance, static dissipation, high-pressure tolerance, and low friction for gas flow, suitable for natural gas, LPG, and biogas. Widely used in urban gas networks, industrial parks, and overseas energy projects as FBE-coated underground and overhead gas pipelines.

Core Advantages

1. Dual-Resistance Safety

Anti-Static: Epoxy coating dissipates frictional static quickly, eliminating spark risk during gas transportation.

Flame-Retardant: High oxygen index material, self-extinguishing when away from fire, resists ignition and flame propagation, improving safety in gas networks.

2. Performance Features

Corrosion Resistance: Double-layer FBE epoxy protects against acid, alkali, salt, and groundwater corrosion. Suitable for buried installation in saline, humid, or underground conditions.

Efficient Gas Transport: Smooth internal surface reduces friction and energy loss, suitable for long-distance gas delivery.

Coating Adhesion: Base metal prepared to Sa2.5, strong coating adhesion ensures minimal peeling or damage during backfilling, welding, or handling.

Temperature Range: Operates from -30°C to 100°C, adaptable to diverse climates including tropical, cold, and high-altitude projects.

Pressure Stability: Suitable for medium and high-pressure networks, tight sealing, zero leakage risk.
