Recently，2023 Annual Meeting of Steel Pipe Sub-Technical Committee of National Steel Standardization Technical Committee and Two National Standards Examination and Approval MeetingSuccessfully held in Xiamen, Fujian，A total of 112 delegates from 87 units attended the meeting.。At the meeting，ByXCMG HydraulicPresided over the formulation《Precision seamless steel tube for hydraulic cylinder of engineering machinery》And other national standards have been approved.。

《Precision seamless steel tube for hydraulic cylinder of engineering machinery》The standard is an important product standard in the steel pipe industry.，Hydraulic cylinder suitable for large and kiloton super-large engineering machinery。

Since 2012，XCMG Hydraulic R & D Team Leads a Number of Large Steel Pipe Enterprises in China，CoordinatedCold drawnAnd follow upMachiningManufacturing process research，It takes ten years to sharpen a sword.，Finally, the key materials and technologies were broken through.。

For will“XCMG experience”Generalization from point to area，September 2022，Xugong Hydraulic has convened more than 20 leading enterprises in the industry to preside over the formulation.《Precision seamless steel tube for hydraulic cylinder of engineering machinery》National Standards，Help China's construction machinery catch up with the international advanced level from the perspective of the whole industry。

Precision seamless steel pipe products for hydraulic cylinders of construction machinery areHigh strength and toughness、Long stroke hydraulic cylinderKey basic materials，Internal diameter with high precision、Wall thickness dimension，WithTo meet the processing quality of hydraulic cylinder，Its effect on the mechanical properties of steel、The parameter inspection of process performance puts forward higher requirements.，To ensure the safe use of steel pipes under severe working conditions。

“This standard is the first international standard of the same kind in China.， Belong to International leading level，It will be submitted to the National Standardization Committee for approval and release.。”Excellent Observer of Steel Pipe Sub-Technical Committee of National Steel Standardization Technical Committee、Wang Jiacong, technical specialist of Xugong Hydraulic, introduced it to you.。

August 2016，XCMG Hydraulic presided over the formulation for the first time《Seamless steel tubes, precision bore, cold-drawn or cold-rolled for hydraulic and pneumatic systems and equipment》National standards issued；May 2018，Asia has the highest level of automation、The cold-drawing machine with the longest travel has been built and put into operation in the new hydraulic plant of XCMG；May 2021，XCMG Hydraulic Products Selected for CCTV Large-scale Industrial Documentary《A great power weighs heavily》，Demonstrate the manufacture of hydraulic cylinders“Unique skills”。

Xugong is continuously cultivating core technology fields.，Help to realize the hydraulic cylinder made in China“Long and thin wall”，Keep improving. YeahBasic raw materials for construction machineryR & D breakthrough and deep processing capability，Provide strong support for core components to grasp market initiative。
