    Frequently asked questions

    Seamless pipes have no welds, high strength and pressure resistance, and are suitable for high demand working conditions; Welded pipes have welded seams, which have lower manufacturing costs and are suitable for applications with low pressure requirements.

    The compressive strength of seamless pipes depends on their material, wall thickness, and production process. High pressure seamless pipes require high strength and are commonly used in oil pipelines and boilers.

    Common anti-corrosion treatment methods for seamless pipes include galvanizing, painting, coating, plastic lining, etc. The specific anti-corrosion method should be selected according to the usage environment and medium.

    The pressure bearing capacity of seamless pipes depends on the material, wall thickness, and outer diameter. Generally speaking, the thicker the wall and the smaller the outer diameter, the higher the pressure bearing capacity.

    The quality inspection methods for seamless pipes include ultrasonic testing, magnetic particle testing, X-ray testing, hydraulic testing, and chemical composition analysis to ensure their strength and quality.

    When choosing seamless pipes, appropriate materials, specifications, and surface treatments should be selected based on the pressure, temperature, fluid medium, and usage environment of the project to ensure the safety and service life of the pipeline.
