The real-world performance of our Hydraulic Cylinder Seamless Steel Tube speaks volumes about its quality and reliability. Here are a few examples showcasing its impact across diverse industries and direct feedback from our valued clients.
A leading global manufacturer of heavy excavators approached us seeking a solution for frequent hydraulic cylinder failures in their boom and arm mechanisms. Their existing tubes, sourced from a different supplier, exhibited premature wear on the internal surface, leading to seal degradation and oil leaks, resulting in significant downtime and warranty claims. We provided customized Hydraulic Cylinder Seamless Steel Tube with an SRB finish (Ra
Outcome: After implementing our tubes, the manufacturer reported a 40% reduction in hydraulic cylinder related failures over a 24-month period. Seal life was extended by over 50%, and operational efficiency improved due to reduced friction. The client noted, "The consistency and superior surface quality of CBI's tubes have dramatically improved the reliability of our equipment. This has been a game-changer for our field performance."
An engineering firm specializing in subsea equipment for offshore oil platforms required hydraulic tubes capable of withstanding extreme pressures (up to 400 bar) and highly corrosive saltwater environments. Standard tubes showed signs of pitting corrosion and fatigue cracking within months. We supplied tubes crafted from a specialized 27SiMn alloy, featuring enhanced corrosion resistance and induction hardened inner surfaces for additional durability, all rigorously hydrostatic tested at 1.5 times the operating pressure.
Outcome: The new cylinders equipped with our tubes demonstrated exceptional performance, with no signs of corrosion or pressure degradation after 3 years of continuous subsea operation. The client praised our technical team, stating, "CBI's ability to provide a truly custom solution for our demanding subsea application was unparalleled. Their tubes have significantly extended the operational lifespan of our critical equipment."
A1: Seamless tubes offer superior structural integrity, as they have no welded seams, eliminating potential weak points for failure under high pressure or cyclic loading. They provide more uniform material properties, better dimensional stability, and are less prone to leakage, leading to a longer service life and higher safety factor in critical hydraulic applications.
A2: We primarily offer Honed and Skived & Roller Burnished (SRB) finishes. Honed tubes typically achieve an Ra (average roughness) of ≤ 0.4 µm. SRB tubes, through a cold-working process, can achieve an even finer finish, often Ra ≤ 0.2 µm, significantly enhancing seal life and reducing friction. The choice depends on the specific application's pressure, speed, and seal requirements.
A3: Our products adhere to a range of stringent international standards, including but not limited to EN 10305-1 (Seamless cold-drawn tubes), ASTM A519 (Seamless carbon and alloy steel mechanical tubing), JIS G3445 (Carbon steel tubes for machine structural purposes), and ISO 3304 (Plain end seamless precision steel tubes for hydraulic and pneumatic power systems).
