High Pressure Hydraulic Tube

DIN2391 seamless precision hydraulic steel tube

As the professional  precision seamless hydraulic steel tubing manufacturer, Wuxi YUTONG produces and supplies DIN2391 seamless precision tubes in a wide range of materials.

The popular steel grades of our precision hydraulic tubes including:

• DIN 2391: ST37, ST37.4, ST35, ST52;
• EN 10305-1 / EN 10305-4: E235, E355, E255
• Other steel grades are available upon customer’ request with a certain min. order quantity.

CHEMICAL COMPOSITIONS OF HYDRAULIC STEEL TUBE MATERIALS

• High dimension accuracy to ensures our high pressure hydraulic tubes can tightly connect to the pipe fittings, thus our precision seamless pipes have excellent performance on preventing leakages.
• Superior surface finish
• High yield strength
• Dimensional accuracy and excellent micro-structure uniformity
• Enhanced machinability
• High strength to weight ratio
• Tight tolerances, resulting in reduced machine time
• Possible spiraling eccentricity inherent in product
• 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 hydraulic steel tubing is very good

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.
