A honed pipe is a precision steel tube that has undergone an internal honing process to achieve a smooth surface finish and accurate dimensional tolerance.
It is primarily used as a hydraulic cylinder barrel or pneumatic cylinder tube due to its excellent roundness and straightness.
Also known as honed tube, hydraulic cylinder honed pipe, or precision honing pipe, it ensures reliable sealing performance and long service life of hydraulic systems.
Honed pipes provide superior surface roughness, typically Ra ≤ 0.4μm, which reduces friction and minimizes seal wear.
They feature accurate inner diameter tolerances, ensuring perfect fit for piston rods in hydraulic cylinders.
The smooth bore surface enhances fluid flow and efficiency in hydraulic and pneumatic applications.
Additionally, honed pipes exhibit excellent mechanical strength, durability, and corrosion resistance when paired with protective coatings or treatments.
Honed pipes are usually manufactured from high-quality seamless steel tubes such as ST52, CK45, SAE 1020, and 42CrMo4.
These materials are chosen for their superior machinability, strength, and fatigue resistance.
In special applications, stainless steel honed pipes may be used to resist corrosion in marine, chemical, or food-processing environments.
Honed pipes are widely used in hydraulic cylinder barrels, pneumatic cylinders, and precision machinery.
They are an essential component in construction equipment, agricultural machinery, mining machines, and lifting platforms.
Other uses include industrial presses, injection molding machines, and offshore engineering equipment.
Due to their smooth bore and consistent hardness, honed pipes are also suitable for high-pressure hydraulic tubing systems.
Honed pipes are available with inner diameters ranging from 30mm to over 500mm.
Custom dimensions are available based on specific hydraulic cylinder requirements.
Standard lengths can reach up to 12 meters, with options for cutting and machining to custom sizes.
Longer lengths ensure versatility for different machinery applications.
The honing process ensures surface roughness Ra ≤ 0.4μm, guaranteeing smooth piston movement.
This specification is essential for reducing energy loss and improving sealing efficiency.
Straightness tolerance is usually ≤ 0.5/1000mm.
Accurate straightness ensures stable hydraulic cylinder performance under high pressure.
A honed pipe is finished using an abrasive honing process that removes material and improves surface quality.
A skived and roller burnished tube, on the other hand, is produced through a cutting and cold working process that compresses the surface layer for extra hardness.
Both provide excellent dimensional accuracy and smooth bore, but skived and burnished tubes often have higher efficiency and reduced processing time.
Selection depends on cost, performance requirements, and application type.
To extend the lifespan of honed pipes in hydraulic cylinders, regular inspection and cleaning are necessary.
Operators should check for scratches, pitting, or corrosion inside the bore.
Using high-quality hydraulic oil reduces wear and prevents contamination damage.
Proper storage with anti-rust coating also protects the honed pipe before installation.
Yes, honed pipes can be customized to meet specific customer requirements.
Custom options include inner diameter, wall thickness, length, and tolerance levels.
Special steel grades and coatings are also available for harsh environments such as marine, mining, or chemical industries.
Customized honed tubes help OEM manufacturers achieve better compatibility and performance in hydraulic and pneumatic systems.
