TIME: 2016-12-10

On December 10, Luo Jun, a distinguished expert of the company and a senior engineer of the national model worker, made a special study on the thread processing of the expanding rod of the expanding machine of FONTIJINE GROTNES, the Netherlands of PetroChina Julong Steel Pipe Company in our conference room. FONTIJINE GROTNES, a Dutch company, uses a new type of double headed nut connection for the expanding rod of the expanding machine. A threaded coil is used between the nut and the rod thread to reduce wear and vibration, effectively avoiding fatigue failure caused by direct thread connection. The processing difficulty of this thread is so high that it has been developed and produced for the first time in China.

In 2016, Luo Jun was elected as the Party Representative of the 11th Party Congress of Hunan Province with honor. As an employee of China Ordnance Group Jianglu Electromechanical Group Co., Ltd., he has been engaged in mechanical processing work for 28 years and is a senior engineer and senior technician in automotive engineering. He has won "National model worker", "National May Day Labor Medal", "Special Allowance of the State Council", "National Technical Expert", "Master of Skills in Hunan Province", "Famous Teacher Award for High skilled Personnel Training in Hunan Province" and other honors, and is the "Key Skill Leader" of China National Weapons Corporation.
