what is hydraulic steel tube ?

 The hydraulic steel tube is cylinder-like shaped tubing device that when attach to hydraulic systems, allow for the passage of fluids within and among components. The tube standard specifies dimensions for cold drawn finishing and ​seamless precision steel tubes. Cold drawn process provides the tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic tubes are suitable in high performance piping system application.

Hydraulic steel tube is basically divided into the hydraulic system with fluid pipe and oil cylinder, also known as honing tube, and cold drawn or cold rolled precision seamless steel pipe also contains hydraulic tube.
Hydraulic pipe after finishing, no oxidation bright heat treatment of raw materials (NBK), nondestructive testing, steel pipe inner hole through high pressure washing, pickling, block on both ends of the steel tube inside and outside wall with anti-rust oil antirust processing, used as a dustproof. To produce steel pipes with high precision, finish good, tube inside and outside wall without oxidation layer, steel pipe can bear the high pressure of fluid flow through, and the steel tube cold bending deformation, flaring, flattening without cracks.Mechanical properties can be bending deformation under any Angle.

40CR ALLOY STEEL SPECIFICATION

  40Cr steel  is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering. DATASHEET & SPECIFICATION The tables below list 40Cr alloy steel datasheet and specification including chemical composition, properties and heat treatment, etc. 40CR STEEL CHEMICAL COMPOSITION   Chemical Composition (%) Grade C % Si Mn Cr 40Cr 0.37 – 0.4

Skiving &Roller Burnishing Tube And Honing Tube

Image
Skiving and roller burnishing tube  process provide high quality hydraulic cylinders with final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores. They are used in the manufacturing of  hydraulic cylinders . Compared to honing process, they are 80-90% saving of machine time which reduces tool costs per meter of tube length and produces super finish surface, with a bore tolerance of IT8, thereby reduces the sealing wear making it ideal for pistons. The skiving tool is a multifunctional tool used in the manufacturing of hydraulic cylinders. Skiving is operated like this: Two thin chips are cut at a high feed rate (1-4 mm/rev) while the tool passes through the work piece. This cutting operation determines the finished diameter and tolerance of the hydraulic tube. Surface finish Ra= 4-10 μm (skiving) Skiving has obvious advantages compared with honing: • 80-90% saving of machine time which reduces tool costs per meter of tube length. • Produ

What is Hydraulic Ram Cylinder?

Image
  Hydraulic ram cylinders   are typically used to give vertical motion, including lifting loads in a vertical direction. Such a cylinder is also used to provide the motion in a horizontal direction but needs attention and suitable guides to guide the motion. Single-acting hydraulic cylinders that have no pistons but have large  cylinder rod s are called rams. These rams operate exactly like the conventional single acting hydraulic  cylinders. However, they use large diameter rods in place of pistons and piston seals in their designs. Thus, in place of pistons, rams have high-pressure cap-end ports. They also do not have any low-pressure rod-end ports. Rams are generally cheaper than their conventional single-acting cylinders counterparts.
