Galvanized Seamless Steel Pipe For Fluid, Gas And Petroleum Transmission

Galvanized seamless steel pipe for fluid, gas and petroleum transmission is manufactured by precision seamless pipe production combined with hot-dip galvanizing anti-corrosion technology. Made of high-quality carbon steel, the pipe is integrally formed without welds, fundamentally avoiding leakage and cracking risks at weld seams. The pipe body is covered with a uniform and dense hot-dip galvanized protective layer, featuring high strength, high pressure resistance, superior corrosion resistance and long service life. Designed for harsh working conditions of petroleum, fluid and gas transportation, it is widely used in petrochemical, gas supply, municipal fluid engineering and industrial oil & gas pipelines, serving as the preferred pipe for industrial fluid transmission systems.

Seamless integral forming, pressure & leakage resistant

Produced by hot piercing and rolling of round steel. No welded joints, stable structure. Capable of long-term operation under medium and high pressure, preventing oil/gas/fluid leakage and pipe burst to meet pressure requirements for petroleum and high-pressure gas transport.

Hot-dip galvanized coating, weather & corrosion resistant

Standard hot-dip galvanizing delivers zinc coating thickness of 40–100μm with strong adhesion and full coverage. Resists moisture, acid, alkali and oil-gas corrosion, isolates oxidation. Service life in underground, outdoor and mildly corrosive environments is much longer than ordinary welded pipes.

Complete specifications & customization available

OD, wall thickness and length can be customized, including SCH40, SCH80 and other ASME wall thicknesses. Pipe ends can be plain, beveled or threaded for welding, threading and flanged connections.

Smooth inner surface, no medium contamination

Dense galvanized layer resists scaling and will not contaminate conveyed media to ensure safe oil, gas and fluid transportation.
