Founded in 1953, Bluestone Group Co., Ltd., an industry standard drafting unit, is a large-scale enterprise specializing in the research and development, design, production and service of plate heat exchangers and other products
Lanzhou Lanshi Heat Exchanger Equipment Co., Ltd. is a subsidiary of Bluestone Group Co., Ltd., specializing in the research and development, design, production and service of plate heat exchangers. It is also one of the drafting units of GB 16409-1996 "Plate Heat Exchanger" standard and CJ/T 191-2004 "Plate Heat Exchanger Unit" industry standard of the Ministry of Construction.
In 1965, we designed and manufactured China's first BP05 plate heat exchanger, and for more than 40 years, relying on the support of Bluestone Group Company, we have successfully developed more than 50 series of detachable plate heat exchangers, heat exchanger sets, all-welded plate heat exchangers, wide-channel welded plate heat exchangers, pressure welded plate heat exchangers, plate and shell heat exchangers, plate and frame heat exchangers, pressure vessels, volumetric heat exchangers, plate evaporators, two-stage coolers, marine skid-mounted and other products.
Among them, the plate heat exchanger produced by the company ranked first in the industry spot check of the "National Petroleum Drilling and Refining Equipment Quality Supervision and Inspection Center" for 16 consecutive years, and the BR1.6 detachable plate heat exchanger was one of the national key scientific and technological research projects during the "Eighth Five-Year Plan" period, and won the second prize of scientific and technological progress in Gansu Machinery Industry in 1999; In 1997, the company successfully developed the all-welded plate heat exchanger, expanded the application range of the traditional rubber sealed plate heat exchanger, filled a gap in China's plate heat exchanger industry, and won the 2002 Gansu Province Excellent New Product and New Technology Award and the second prize of Gansu Machinery Industry Science and Technology Progress Award; In 2002, the research and development of wide-channel welded plate heat exchanger was successful, breaking the monopoly of foreign companies on the Chinese market, and the wide-channel welded heat exchanger has been widely used in the domestic sand alumina production and large-scale production of fuel ethanol. In 2003, the company was the first in the same industry in China to obtain CCS and BV classification licenses, and provided a large number of products for the shipbuilding industry; In 2005, it obtained the only civil nuclear safety equipment product design and manufacturing license in China; At present, it is the only licensed enterprise in the same industry in China.
In response to the call of the state to improve the localization of the core equipment of million-kilowatt nuclear power units, the company has independently developed H450H500 series of large-scale plate heat exchangers, which have been evaluated as excellent technological innovation products in Gansu Province by the Gansu Provincial Economic Commission, Gansu Provincial Science and Technology Department, and Gansu Provincial Bureau of Quality and Technical Supervision, and have been successfully applied to many nuclear power plants; Some of these models have been successfully applied to the world's first set of third-generation pressurized water reactor nuclear power technology AP1000 nuclear island units developed by Westinghouse in the United States, writing a new page for the company's development; In order to meet the needs of the project of improving the industrial capacity of plate heat exchangers for million-kilowatt nuclear power plants, the production and office operation area has been expanded, and 30,000 tons of hydraulic presses have been installed, which has improved the company's production capacity and met the needs of high-end markets such as nuclear power; In 2009, in the 60th anniversary of the National Day military parade, the products of Lanshi Heat Exchange Company were displayed, and because of their outstanding contributions, they were commended by the Armored Bureau of the Land Installation Science and Binding Department of the General Armament Department of the Chinese People's Liberation Army and the Armored Army Representative Bureau, and in 2010, it obtained the three-level confidentiality qualification unit certificate issued by the National Defense Weapons and Equipment Research and Production Unit Confidentiality Qualification Review and Certification Committee, and was recognized by Lanzhou City as the first batch of municipal enterprise technology centers in 2011 The Gansu Provincial Development and Reform Commission approved the company to establish a provincial plate heat exchanger engineering research center (engineering laboratory), and successfully passed the review of the General Armament Department of the Chinese People's Liberation Army in 2011 and obtained the registration certificate of the equipment contractor.
