On December 10, Gansu Provincial Commission of industry and information technology announced the list of outstanding new products and technologies in 2014, and the new high-pressure large-diameter all welded ball valve developed by Lanzhou high pressure valve Co., Ltd. was listed on the list

it is expected that the pig iron market will be dominated by weak operation in the near future. On December 10, Gansu Provincial Commission of industry and information technology announced the list of outstanding new products and technologies in 2014, and the new high-pressure large-diameter all welded ball valve developed by Lanzhou high pressure valve Co., Ltd. was on the list

high pressure large diameter all welded ball valve is one of the key equipment of natural gas long-distance pipeline. The natural gas long-distance pipeline crosses deserts, swamps, mountains, rivers, etc., with complex geological conditions and harsh environmental conditions. In order to ensure the safe and reliable operation of the energy artery, the valve is required to have higher reliability, sealing and strength, with a service life of more than 30 years. In terms of design, materials Manufacturing and other aspects put forward high requirements for research and development

on December 15, 2013, Gansu Provincial Commission of industry and information technology organized and held a appraisal meeting for high-pressure large-diameter all welded ball valves, The Appraisal Expert Committee believes that "the high-pressure large-diameter all welded ball valve developed by Lanzhou high pressure valve Co., Ltd. has advanced design, reasonable process and reliable performance, and meets the requirements of the technical conditions for localization and trial production of high-pressure large-diameter all welded ball valve and the test outline for new products of large-diameter and high-pressure all welded ball valve, reaching the" domestic leading level ". The function of the evaporative condenser is to use the low-pressure circulating evaporator as the high-pressure circulating condenser. On october29,2015, the high-pressure large-diameter all welded ball valve successfully passed the approval of the national energy administration and the company's assistant general manager shanghuiming. It will be popularized and used in national major projects such as the transmission of West East gas with high research and production capacity
