introduction

JIS G3473 Hydraulic Cylinder Pipe‌ is a carbon steel pipe specially designed for hydraulic cylinder applications, with standards and specifications designed to ensure the performance and safety of hydraulic systems. This pipe generally has high pressure bearing capacity and good corrosion resistance to meet the needs of hydraulic cylinders in various working environments.
GNEE also provides hydraulic cylinder pipes produced according to JIS G3473 standards that can be processed in various ways, such as cutting, welding, bending, etc. to meet specific installation and use requirements. In addition, these pipes can also be surface treated, such as galvanizing or coating, to improve corrosion resistance and aesthetics.
