ISO H8 Cylinder Tube,Honing Tubing For Hydraulic Cylinders

 ISO H8 Cylinder tube is a cold-drawn steel tube, steel grade ST52 , in accordance with DIN 2391 HONED with ISO-tolerance range H8 on the internal diameter. Basic material for manufacturing welded hydraulic cylinders particularly suitable for the industrial, mobile and special applications sector.

Honing process Of H8 Cylinder Tube
* machining the internal surface of the tube to a precise diameter and surface finish
*  using a honing stone to remove material and achieve the desired surface finish 
* Resulting in a smooth , cylindrical internal surface with a surface finish of Ra 0.2 – 0.4um ( micro – inches)

SKIVING AND ROLLER BURNISHING FOR CYLINDER BORES

  Hydraulic cylinder want to operate effectively, the cylinder’s ID must be precisely round and have a mirror-like surface finish to ensure a tight seal between it and the mating internal piston. This is commonly achieved through skiving and subsequent roller burnishing inside a tubular workpiece. Skiving uses a set of carbide blades positioned around the diameter of a tool to slice away chips and create a geometrically round bore. Roller burnishing , a cold-working process, uses multiple rollers to compress the peaks of material left behind after skiving to generate an extremely smooth surface finish. Burnishing also introduces a residual stress layer into the cylinder wall, which improves cylinder fatigue life. The skiving roller burnishing tool is a multifunctional tool used widely in the manufacturing of hydraulic cylinders and compared to honing the advantages are: • 80-90% saving of machine time which reduces tool costs per meter of tube length. • Produces super finish sur...

THE APPLICATION OF DIN2391 ST52.4 PRECISION HYDRAULIC STEEL TUBE

图片
  ST52.4 Hydraulic steel tubes   are tubes made in accordance to DIN 2391 / DIN 2445. ST52.4 is a high grade steel material, it can withstand higher working pressure with same tube OD size compare to ST37.4 material.  The delivery condition for grade ST52.4 tubes are in NBK finishing, which is normalized, phospated, and oiled inside and outside. Hydraulic tubes ST52.4 are measured by Outer Diameter (OD) and in varies tube thickness (THK). Difference of OD and tube thickness lead to different working pressure. ST52.4 Precision Hydraulic tube  is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure stainless steel tubing. In the field, high-pressure tubing is used for down-hole control systems, hydraulic and pneumatic piping, chemical injection modules, vacuum systems, and much more. Chemica...

WHAT IS A MULTI-STAGE HYDRAULIC CYLINDER?

  Multi-stage hydraulic cylinders  are a recent innovation that have enabled us to customize and enhance the application of various types of machinery. They are used for a wide range of applications including cultivation, construction, and civil engineering. Let’s take a look at the benefits and applications of multi-stage hydraulic cylinders. The primary advantage of the multi-stage hydraulic cylinder lies in the extension capabilities of its cylinder shaft , allowing it a far longer stroke when compared with other cylinders. It consists of various tubular rods known as sleeves. These sleeves (usually five or six) are of decreasing diameters and are placed within each other. Once pressure is pumped into the cylinder , the largest sleeve (also known as barrel or main) is the first to extend. It is followed by subsequent sleeves up to the last one (known as a plunger) until it reaches its maximum extension. The compact design of the custom multi-stage hydraulic cylinder or tel...
