In the production process of offshore and onshore natural gas treatment facilities, all pipelines are mainly high temperature and high pressure valves. During the operation of high temperature and high pressure valve, the leakage of main seal is the main factor affecting the failure of the whole high temperature and high pressure valve. In today's production, technicians must pay attention to the main seal leakage of high temperature and high pressure valves. This paper studies the main seal leakage of high temperature and high pressure valve, effectively analyzes the root causes of the leakage, deeply summarizes the practical measures to solve the main seal leakage of high temperature and high pressure valve, and continuously improves the production quality of high temperature and high pressure valve.展开更多

Ensuring the quality of public service is an important task for the functional departments and practitioners of state-owned enterprises in a period of time. As a key role in the "three standards" (standardized team, standardized post, standardized site) system construction in state-owned enterprises, especially the grass-roots management, is undoubtedly an important means to realize the value of state-owned enterprises public service under the new situation. Based on this, this paper combines with the work practice, and detailed expounds the creation and practice of the "three standards" management and promotion system in the public service of state-owned enterprises under the new normal.展开更多
