Product Introduction

gnee pipe team

GB 18248 37Mn seamless hydraulic pipe is a seamless steel pipe specially used in hydraulic systems. Its manufacturing and quality control comply with China's national standard GB 18248. This kind of steel pipe is made of 37Mn (No. 37 manganese steel), which has high strength and good plasticity, toughness and welding performance.
Seamless hydraulic pipes are mainly used to manufacture various hydraulic equipment, hydraulic systems and hydraulic transmission devices, such as hydraulic pumps, hydraulic cylinders, hydraulic motors, control valves, hydraulic pipelines, etc. In these applications, seamless hydraulic pipes need to withstand certain pressures and temperatures, so the steel pipes are required to have sufficient strength and corrosion resistance.
