honed tubing

Honed tube is well known as hydraulic cylinder tube in many industries. This is because honed tubes are the most important materials of manufacturing hydraulic cylinders. And as this kind of tubing is usually honed in tube inside diameter, it is known as honed ID tubing also.

Product Details

honed tubing Advantage

  1. arrow icona. High strength: Thick-walled spiral steel pipes have high tensile strength and yield strength, are suitable for withstanding large internal and external pressures, and provide solid support for various projects.
    b. Good welding performance: High-quality steel and double-sided submerged arc welding process ensure high strength and high quality of welded joints.
    c. Superior stress resistance: The spirally distributed welds help disperse and release stress, improving the stress resistance of the steel pipe.
    d. High flexibility: The diameter and wall thickness of thick-walled spiral steel pipes can be easily adjusted during the production process to meet the needs of different application scenarios.
    e. Strong corrosion resistance: High-quality steel and surface treatment technology can provide good corrosion resistance and ensure the service life of steel pipes in harsh environments.
    f. Saving resources: Due to the high strength of thick-walled spiral steel pipes, thinner wall thicknesses can be used to achieve material savings on the premise of meeting engineering requirements.
    Application fields: Thick-walled spiral steel pipes are widely used in various engineering fields, such as oil, natural gas, water conservancy, electric power, construction, bridges, etc. Its excellent performance characteristics make it an indispensable basic building material in various projects.
