A smooth inner surface (Ra 0.2 m) minimizes friction and wear, improving sealing and extending equipment life. Tailored for rigorous mechanical engineering tasks, this product guarantees excellent strength and durability through its robust materials and thorough testing protocols.
Customizable to Your DemandsAvailable in a range of diameters (20500 mm inside, 25600 mm outside), wall thicknesses (250 mm), and lengths up to 12 meters, these tubes can be custom-manufactured according to drawings or specifications. Options include various steel grades (ST52, E355, CK45, SAE 1020, ST37, ST44) and multiple surface treatments such as honing, phosphating, polishing, and chrome plating, ensuring compatibility with diverse industrial applications.
Reliable, Ready-to-Use, and Delivered SecurelySupplied in a honed and burnished condition, each tube is immediately usable upon delivery. Strict adherence to seaworthy packing standards, with protective end caps, safeguards the product during transport. Rigorous 100% eddy current and ultrasonic testing, along with checks on chemical and mechanical properties, ensures consistent quality, corrosion resistance, and adherence to global industry standards.
FAQs of Hydraulic Cylinders Honed Burnished Tubes:
Q: How are honed burnished tubes produced for hydraulic cylinders?
A: These tubes are manufactured using cold drawn or hot rolled techniques from seamless or carbon steel, then honed and burnished for a precise, smooth bore. This process ensures excellent straightness, roundness, and superior surface finish, meeting stringent mechanical and corrosion resistance requirements for hydraulic applications.
Q: What are the key benefits of using these tubes in hydraulic and pneumatic cylinders?
A: Honed burnished tubes offer minimal friction, enhanced sealing capability, and reduced wear due to their superior surface finish and tight tolerances. These properties result in longer service life, higher efficiency, and reliable operation in hydraulic and pneumatic systems.
Q: When should I choose a customized tube specification?
A: Customization is ideal when your application demands specific dimensions, grades, or surface treatments beyond standard offerings. You can request tubes tailored to your unique requirements, including varying inner/outer diameters, wall thicknesses, lengths, or material grades, ensuring perfect integration into your equipment.
Q: Where are these hydraulic cylinder tubes typically used?
A: Primarily, these tubes are integral components in hydraulic and pneumatic cylinders across industries such as construction, agriculture, mining, and mechanical engineering, as well as in manufacturing plants for automation and heavy machinery.
Q: What testing process guarantees the quality of these tubes?
A: Every tube undergoes comprehensive non-destructive testing, including 100% eddy current and ultrasonic inspections, as well as chemical and mechanical property analysis. This rigorous approach ensures that each tube meets strict international standards and delivers consistent performance and durability.
Q: How is corrosion resistance achieved in these honed burnished tubes?
A: Corrosion resistance is provided through careful selection of materials, optional surface treatments such as phosphating and chrome plating, and strict quality control throughout the manufacturing and finishing processes. This ensures longevity even in challenging environments.
Q: What makes these tubes immediately ready for use upon delivery?
A: Tubes are supplied in a honed and burnished, finished state, packaged with protective end caps and seaworthy packing. This ensures they remain clean, undamaged, and require no further processing before installation, saving time and labor on site.
