What is H8 honed tube?

 ISO h8 honed tube also can be called h8 cylinder tube/cylinder barrel. It is manufactured by precision seamless tube with very tight tolerances, fully prepared for use in hydraulic and pneumatic cylinders.The ST52 steel used in this tube is E 355 according to EN 10305-1.This type of tube is used in hydraulic and pneumatic circuits, the H8 tolerance both in diameter and roughness allow them to be ready-to-use tubes.

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...
