Precision Hydraulic Cylinder TubesDesigned for critical hydraulic and pneumatic applications, these honed and burnished tubes feature an impressive inner roughness (0.2 m Ra) to minimize friction and wear. Offering reliable straightness and customizable sizes, they enhance operational longevity and performance in heavy-duty actuators, presses, and industrial machines.
Uncompromised Quality and StrengthEach tube is manufactured using seamless cold-drawn techniques from high-grade carbon steel (ST52, E355, SAE1020, CK45, etc.), delivering substantial yield and tensile strengths. Comprehensive testing protocols ensure every tube meets stringent industry standards, while chamfered and deburred edges promote safe handling and assembly.
Versatile Applications and Timely SupplyWith a monthly production capacity of up to 10,000 meters and a supply network spanning India, we accommodate orders of various lengths and outer diameters. The tubes round profile and corrosion-resistant surface treatment make them ideal for hydraulic cylinder repair, new builds, or heavy machinery upgrades.
FAQs of 300 mm Hydraulic Cylinders Honed Burnished Tubes:
Q: How are the 300 mm hydraulic cylinder tubes manufactured and finished?
A: These tubes are created using seamless carbon steel and processed via cold drawing, followed by precision honing and burnishing techniques. This ensures a mirror-like inner surface finish (0.2 m Ra) and high straightness, meeting DIN2391, EN10305, and ASTM A519 standards. Each tube is then chamfered or deburred at the ends for safety.
Q: What testing processes are performed on these tubes before delivery?
A: Every tube undergoes ultrasonic, eddy current, and hydraulic pressure testing. These measures verify structural integrity, detect material flaws, and ensure that the tube can withstand operating pressures typical in hydraulic and pneumatic cylinders.
Q: When should honed and burnished tubes with high straightness and fine inner finish be used?
A: These tubes are recommended whenever hydraulic or pneumatic cylinders require low friction, precise movement, and long service life. Applications include industrial hydraulics, construction equipment, and heavy machinery where durability and precise actuator motion are critical.
Q: Where are these hydraulic cylinder tubes primarily used?
A: They are mainly used in manufacturing, maintenance, and repair of hydraulic and pneumatic cylinders. Sectors such as construction, mining, material handling, and general industrial machinery frequently require these tubes for their hydraulic actuators.
Q: What are the main benefits of using tubes with HB 180-230 hardness and strong corrosion resistance?
A: The specified hardness range offers optimal resistance to abrasion and wear, extending the cylinders operational lifespan. Surface treatments enhance corrosion resistance, making the tubes suitable for demanding environments and reducing maintenance requirements.
Q: Can the tubes dimensions and surface treatments be customized?
A: Yes, the tubes are available in a wide range of wall thicknesses (5 mm 25 mm), lengths (up to 12 meters), and outer diameters (typically 310 mm, customizable). Surface treatment options are available to further enhance corrosion resistance based on application needs.
