Brief introduction of Lanzhou Shi Lan Group Co., Ltd.

Lanzhou Shi Lan Group Co., Ltd. (Shi Lan Group for short) was established on 1953. Its predecessor was the merger of Lanzhou Petrochemical Machinery Factory and Lanzhou Petrochemical Equipment Factory, which were the key construction projects of 156 during China's first five-year plan period. Over the past 60 years, it has gone through a glorious course. From the first deep-well oil drilling rig in China to the first ideal drilling rig in the world, from the first high-pressure vessel in China to the 2.2 million tons high-pressure hydrogenation reactor with the highest annual processing capacity in the world, it is the earliest, largest and strongest large-scale high-end energy equipment leading enterprise group integrating oil drilling, oil refining, R&D and general machinery design and manufacturing in China. From the 4500-ton fast forging hydraulic unit supported by the national "Eleventh Five-Year Plan" scientific and technological research project to the manufacture of heat exchanger equipment for million kilowatts nuclear power heat island, there are sapphire drilling and mining machinery all over the world, and domestic oil refining enterprises have sapphire refining equipment. Shilan people have filled many domestic and international gaps in the new China petrochemical equipment industry 100, won scientific and technological awards at or above the provincial level 156, 95 patents, presided over the formulation of 44 national standards and 5 industrial standards1. As the pioneer of petrochemical machinery in China, Shilan people are known as "the cradle and backbone of petrochemical machinery in China" and as "the meritorious enterprise equipped with China" by China Machinery Industry Federation. Shi Lan Group is one of the first batch in China to obtain the national Class III pressure vessel design and manufacturing license, ISO900 1 quality certification, IS0 1400 1 environmental management system, GB/T2800 1 occupational health system certification, CNAS national laboratory certificate, nuclear product design and manufacturing enterprise certificate, first-class measurement standard unit, and so on. Take the lead in obtaining American API mark license, ASME certificate, steel seal and NBBI-R certificate in China. Shi Lan Group has world-class and domestic leading strength in energy equipment product production, technology R&D and design. The Group can independently develop, design and produce 1.500m- 1.3000m oil and gas drilling rigs and acquisition equipment, independently undertake large-scale offshore petroleum projects, and develop, design and manufacture various high-end, serialized and intelligent refining and chemical plants, large-scale rapid forging equipment, nuclear power plants, various heat exchange equipment and new energy equipment according to user requirements. Shi Lan products have been widely used in petroleum, chemical industry, metallurgy, automobile, railway, aerospace, military industry, nuclear power, new energy and other fields. Products are exported to dozens of countries and regions on seven continents and enjoy a first-class reputation in the same industry at home and abroad. The domestic market share of drilling rig products produced in Shi Lan once reached over 90%, pumping units accounted for 65% of the total output of pumping units in the national mechanical system, and refining equipment accounted for over 30% of the total products in the national refining equipment manufacturing industry. The Group covers an area of 6,000 mu, with nearly 10,000 sets of various large-scale equipment, and has three R&D, design and production bases in Lanzhou, Lanzhou New District and Qingdao. National Technology Center 1 each, National Laboratory 1 each, and 3 provincial technology centers. There are more than 8,000 employees and more than 3,000 professional technicians. In the future, the Group will adopt a diversified development strategy based on high-end equipment R&D and manufacturing industry, supported by real estate and modern service industry. Aim at the cutting-edge technology in the global market and build an international group integrating R&D, design, engineering production and intelligent whole-process service. In particular, new breakthroughs have been made in new energy equipment such as deep oil drilling and production, large-scale intelligent offshore oil drilling platforms, shale gas, combustible ice, super-large engineering intelligent refining devices and nuclear power. At the end of the 12th Five-Year Plan, the Group's sales revenue exceeded10 billion yuan, and in 2020, the sales revenue exceeded 30 billion yuan. Strive to build a century-old leading enterprise of Shi Lan Petrochemical Equipment.
