It has more than 30 metrological verification qualifications, such as long, heat, power and electricity, etc., authorized by the higher competent department.
Jinzhong group insists on technological progress and new product development, and always leads the domestic industry in the research and development, trial production and application of new technologies, new materials and new processes. In high temperature and high pressure, corrosion resistance, low temperature, large, alien, thick wall, composite, multi-layer, non-ferrous metals, nickel base materials, zirconium, hartz alloy and other high-end equipment research and development, design and manufacturing has a lot of successful experience, advanced technology, reliable quality, performance significantly, there are many products to replace imports, to fill the domestic blank, won the national gold, silver, high quality products, scientific and technological progress, major technical equipment localization and other awards, the use of new materials and new technology has won the award of the State Council, the formation of the core technology of the gold weight group, greatly enhance the market competitiveness.
Gold group is the earliest application of American ASME, eu EN China, Germany, Japan JIS, AD KC in the Netherlands and other advanced foreign standards for equipment design and manufacturing enterprises, with dozens of famous foreign companies design and manufacture of the more than 1500 sets of equipment, including the American ASME specification design, fabrication, inspection and ASME "U" steel products more than 300 sets, and foreign customers throughout Europe, America, Asia, Africa and other countries and regions.
Jinzhong group has the ability to provide complete sets of pressure vessel equipment for large-scale chemical industry, coal chemical industry, oil refining, chemical fertilizer and other process equipment, and has the performance of providing process package for modern coal chemical gasification island and general contracting for gasification island. Main equipment: ammonia synthesis, urea synthesis tower, CO2 stripping tower, high-pressure condenser, high-pressure scrubber, urea/zirconium bimetal tube ammonia stripper, ammonia synthesis tower, ammonia separator, gas/gas heat exchanger, etc. Hydrogenation reactor, reforming reactor, tower, heat exchanger, separator, spherical tank, paraffin molding machine, rubber extruder, casing crystallizer and other equipment in the refinery plant; Chemical furnace, gasifier, heavy ash forging furnace, sand coal filter, hydrating reactor, coke cooler, converter and other equipment in chemical, coal and salt chemical plants. It can design and manufacture complete sets of plant equipment for 250-700,000 tons/year synthetic ammonia, 4-1.2 million tons/year urea, 1-20 million tons/year oil refining, 8-1 million tons/year ethylene and so on.
Gold weight group manufacturing layer board type high pressure vessel has a history of more than 30 years, in the domestic first 240000 tons/year, 300000 tons/year, 480000 tons/year, 520000 tons/year, 700000 tons/year, 1 million tons/year, 1.2 million tons/year urea plant. The four high voltage equipment, that is, the urea synthetic tower, CO2 stripping tower and high pressure condenser, high pressure washer, is the largest number of enterprises in urea key equipment made in China. In 1986, the high-pressure scrubber was awarded the gold award of national quality management. In 1991, the state council awarded the achievement of the domestication of 520,000 tons of urea plant and the substitution of import. The laminated high pressure vessel can be wrapped in sections or in whole to meet the different needs of customers.
Jinzhong group is located on the coast of the yellow sea, which is closely connected with expressways and railway lines, so its operation is very convenient and smooth.
