High Quality Seamless Steel Pipe for Oil & Gas Carbon Alloy Steel ASTM A106 A53

We supply high-precision seamless steel pipes manufactured under strict quality control (ISO 9001:2015). Unlike ordinary welded pipes, our seamless pipes have no welded joints, offering higher pressure resistance and superior structural integrity.

Our pipes are ideal for high-pressure fluid transportation, mechanical structures, and oil & gas exploration. With full sizes ranging from 6mm to 720mm OD, we support customized lengths and third-party inspections (BV, SGS).

    Product details

    High-pressure fertilizer seamless pipe is a high-pressure pipe specially used for fertilizer production equipment, mainly used to withstand high pressure, high temperature and corrosive media conditions

    Characteristics of high pressure fertilizer pipe

    1.High pressure resistance:

    Working pressure: Able to withstand pressures from 10MPa to 100MPa or even higher.
    Application scenarios: Suitable for high-pressure synthesis towers, pipelines and reactors in fertilizer production.

    2. Corrosion resistance: 
    Corrosive environment: Corrosive media such as ammonia, urea, and nitric acid are often involved in the fertilizer production process.

    Material selection: Usually made of corrosion-resistant alloy steel or stainless steel (such as 316L, 304L).

    3.High temperature resistance: 
    Working temperature: Able to work stably in the temperature range of -50°C to 600°C.

    Application scenarios: Suitable for high-temperature and high-pressure synthetic ammonia, urea and other processes.

    4.High strength and toughness:
    Material properties: With high strength and good toughness, it can withstand high pressure and impact loads.

    Safety performance: Ensure safe operation under extreme working conditions.
    5.Precision size:
    Dimensional accuracy: High dimensional accuracy of inner and outer diameters, wall thickness, etc., to ensure the reliability of installation and use.
    Surface quality: Smooth inner and outer surfaces to reduce medium flow resistance.
