Hydraulic Cylinder Tube

Our hydraulic honed tube can be supplied with ID tolerance of H7, H8, H9, H10 or depends on customers’ request and it’s dimension.

Product Processing: Raw materials- Cold drawn/rolled- Heat treatment (BKS)- Honed – packing.

Below is the chemical composition & mechanical properties of the main steel grades for hydraulic cylinder tube.

Chemical composition(%) Mechanical Properties Of Cylinder Honed tube

1. High precision tolerances; Wuxi YUTONG’s honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

2. Seamless tube with high pressure resistance;We only 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.

3.  Advanced manufacturing equipment and facilities, including: cold drawing machine, cold rolling machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, cutting machine, etc.

4. High Smooth inside surface; The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).

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

6. Good weld ability: The weld ability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.

7. 100% Quality assurance,100% Customers repurchase,Imperial sizes & metric sizes & special size all available. 

8. Reliable Packing: All of YUTONG’s honed tube 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 hydraulic honed tubes will be packed with seaworthy package such as wooden cases.

1.Extensive production experience: more than 20 years manufacturing experience for honed tube and chrome plated rod, in Australia, Peru, Chile, Thailand, Singapore,Columbia,Canada, Mexico,US,Saudi Arabia,Brazil, India, Iran, Indonesia and other countries have long-term buyers.

2.Advanced production equipment: cold drawing machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc. We have professional technicians do regular scheduled maintenance on these machines to guarantee them work well.

3.High quality raw material: our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.

4.High precision: Honed Tube, inside surface roughness 02-0.4 um, straightness max 0.5/1000, strict tolerance DIN2391 H8. Skived & Roller Burnished Tube, inside surface roughness under 0.2 um, straightness max 0.2/1000, strict tolerance DIN2391 H8. Chrome Plated Rod, chrome layer 10 micron to 100 micron, strict tolerance ISO f7.

5.Strict quality control: we have professional in-house QC to inspect all products. We will do Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other tests in need before delivery.

6.Safe packing: an-rust oil on tubes and rods before delivery. Plastic caps on both ends to protect tube inside surface. Then be packed with seaworthy package or in wooden case.
