Honed hydraulic cylinder tubes

Our factory supply honed tubes / hydraulic cylinder tubes, here below is the product details

  1. What is honed tube?

A Honed Tube is usually a CDS (Cold drawn seamless) steel tube or DOM (Drawn Over Mandrel) welded steel tube with inner diameter honed or skived &roller burnished, so honed tubing is with extremely precise Inner Diameter(ID) dimensions and smoothly ID surface. Honed tubes are broadly utilized to manufacturer and repair hydraulic cylinders and pneumatic cylinders. So in many fields, the honed tube is called cylinder tube also.

Besides the materials listed as above, our factory also produces and supplies honed pipes with other materials upon customers’ request.

    • 4.4 Honed cylinder tube Tolerance standard

      • 4.4.1 Honed tubing ID tolerance standard

Our honed ID tubing can be supplied with ID tolerance of H7, H8, H9, H10 and H11 depends on customers’ request and its dimension. Here below is the detailed Inside Diameter (ID) tolerance standard.

For imperial honed cylinder tube sizes, the inner diameter tolerance usually is +0.003”/-0.000”.

      • 4.4.2 Honed tubing Outside Diameter Tolerance standard:

For the O.D tolerance of the honed steel tubing, we can follow the corresponding standards as DIN2391, EN10305-1, DIN1629, DIN 1630, ASTM A513, A519, etc. or upon customers’ request.

      • 4.4.3 Honed tubing Straightness Tolerance

The straightness for honed tubing is also very important, normally our straightness of hone ID tubing is 1mm/meter. However, we can make higher straightness requirement as customers’ request.

    • 4.5 Inner Diameter Manufacturing Method of cylinder tube

Honed cylinder tubes which including hydraulic cylinder tubes and pneumatic cylinder tubes usually are produced by honing processing or SRB (Skived & Roller Burnished) processing after cold drawing and heat treatment. The mother tube we usually use “Suitable To Hone” Cold Drawn Seamless Tubes. The process of the honed ID tubing is determined upon the dimension, mold available and the request of the customer.

      • 4.5.1 Honing

Under the honing process, abrasive polishing stones and paper are used to grind to remove small amounts of material in the tube ID, in order to achieve the required extremely precise ID dimensions tolerances, and to remove surface imperfections from the tube drawing process and get the desired surface finish.
Utilizing the honing process, Younglee can supply honed tubing with ID dimensional tolerances as precise as 0.021mm (H7), and surface roughness better (smoother) than Ra 0.8um.

      • 4.5.2 SRB (Skiving & Roller Burnishing)

The process of Skiving & Roller Burnishing (SRB for short) is a single pass operation that uses a Skiving tool on the forward stroke to skive the tube ID to the required size, and uses roller bearings on the reverse stroke, to burnish the surface to the required roughness. SRB process is faster than honing and normally can produce more precision tolerances and smoother surface finish than honing.
Utilizing the SRB process, Younglee can supply hydraulic cylinder tubing (which are seamless skived tubes) with ID dimension tolerance as precise as 0.021mm (H7), and inside surface roughness smoother than Ra 0.4um.

Normally, hydraulic cylinder tubes and pneumatic cylinder tubing produced by the above two processing are both called Steel Honed Cylinder Tube. Skived &Roller burnished tube is a kind of honed tube. To choose which manufacturing method, it depends on customers’ preference and the ID of the cylinder tube. Sincerely, nowadays more and more honed tubes are manufactured through the method of skiving & roller burnishing.

    • 4.6 Packing of hydraulic cylinder tube

We pack our honed cylinder tube as per Specification A700, latest revision, “Standard Practices for Packaging, Marking, and Loading Methods for Steel Products for Shipment.”

All the honed pipes will be oiled by the anti-rust oil before delivery. And to protect the inner diameter surface of the honed ID tubing, we will cap the tube ends with plastic end caps, or if customer request we can weld a steel cap to protect the inner diameter of the honed id tubing during loading and unloading. And then the honed pipes will be packed with seaworthy package such as wooden cases or plastic bags.

    • 4.7 Advantages / Features of our honed tubing

As one of the main China hone tube manufacturers and suppliers, honed steel tubes produced in Younglee’s factory have features as below.

      • Super Smooth inside surface

The inside surface roughness is Max Ra 0.4 microns ID finish (Max 16Ra ID finish).

      • High precision tolerance

The inner diameter tolerance of ID honed tubing could be H7, H8, H9 according to customers request.

      • Durable in use

As the first class quality honed tube supplier, our factory only uses prime quality raw materials, which insures the honed cylinder tubes durable in use.

      • Seamless tube with high pressure resistance;

We mostly use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

      • Flexible order quantity

We accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.

      • Good weld-ability:

The weld-ability of our honed steel tube is very good, this is quite helpful for manufacturing the cylinders.

    • 4.8 Honed tube Applications

Honed tubing and Skived & Roller Burnished tubes (SRB tube) are mostly used as cylinder tube, such as hydraulic cylinder tube and pneumatic cylinder tubing, which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube usually has very accuracy dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need. For examples, honed tube is suitable for various kinds of Precision Mechanical Tube, Honed Cylinder Tubing and Hydraulic Cylinder, Construct use Multi Joint Tube, Steel Axis Pipe, Injection Machine and Robotic Arm, shock bodies, accumulators, motor housing, pump barrel and so on.

  1. Honed tubing Production Process

Our factory’s honed pipes are manufactured from cold drawn seamless steel tubes. Generally the production process is as below:

Cutting the raw material tube -> Acid pickling the raw tube -> water rinsing the raw pipe -> phosphating and surface lubricating -> cold drawing to make the CDS tube -> heat treating (stress relieved annealing) the CDS tube -> Straightening the cold drawn seamless tubes – > Cut the lengths to the required final lengths -> then honing (or skiving & roller burnishing) the tube inside diameter -> lastly inspecting the tubes and get the finished honed tubes packed.

Here below picture is the production flow chart.
