As we all know, the hot galvanizing of strip steel is because zinc can form a corrosion-resistant film on the metal surface in a corrosive environment (corrosive media such as H2O, O2, and CO2), thereby extending the service life of the material. Galvanizing has become an effective method for anticorrosion of steel materials. Hot-dip galvanized …

Applications in ferrous metallurgy □ Electric furnace steelmaking Blowing oxygen enriched air can shorten melting time, strengthen reaction of removing impurities, and save energy. □ Blast furnace Ironmaking “Oxygen-enriched coal injection” technology reduces coke consumption and production costs and increases blast furnace productivity. Oxygen-enriched blast furnace can increase the temperature of molten iron and fluidity …
Metal production and processing: It can protect metals such as steel, copper and aluminum pin annealing, carburizing and sintering process in high temperature furnaces; cooling extruded film; cold shrinkage of metal parts; and purging of stainless steel pipe welding. In addition, it is also used for plasma cutting; gas protection for aluminum products, aluminum profile …
As the mainstream, traditional laser cutting uses CO2 laser, which can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. Fiber lasers have obvious advantages when cutting thin plates within 4 mm. Due to the wavelength of solid lasers, they are of poor quality when cutting thick plates. Of …
Oil and gas industry: nitrogen filling anti-oxidation or nitrogen purging of pipeline containers in petroleum refining systems, storage tank nitrogen filling, replacement, leak detection, flammable gas protection, etc. Gas purity: 99.9%, gas pressure 0.75MPa. Oil recovery and refining: increasing recovery efficiency and maintaining pressure on oil depots and gas storages; Inert gas protection storage tanks …

With the development of the petroleum industry, oil reserves are declining year by year, and oil exploitation is becoming more and more difficult. However, nearly two-thirds of the crude oil is still blocked underground because it has not been harvested by the first exploitation. Nowadays, new methods and technologies have been explored, which is injecting …

On November 20, 2021, the first domestic LNG/FLNG bypass pipe jointly developed by CNOOC Gas and Power Corporation (“CNOOC”) and Kaifeng Air Separation Group Co., Ltd. (“Kaifeng Air Separation”) The type heat exchanger was successfully started up at the LNG plant of CNOOC Shandong New Energy Co., Ltd., and completed 72 hours of continuous and …
1 General introduction Carbon molecular sieve (CMS) as a new type of adsorbent has developed rapidly since it was industrialized in the late 1960s. CMS is a special activated carbon, mainly composed of micropores below 1nm and a few large pores. Due to its special microporous structure, it can be adsorbed according to the size …
The application of nitrogen in stainless steel laser cutting machines is mainly used as an auxiliary gas in two ways: 1) As an inert gas to prevent oxidation in laser cutting. Maintaining the metallic luster (shiny) of the cut surface of stainless steel products. 2) Blow down the melted part with the pressure of nitrogen …

Why need compression ? For PSA nitrogen oxygen generators, effectively protect the key part, molecular sieve, is of critical importance. When molecular sieve is filled inside the adsorption towers,as molecular sieve gravity is downwards, while gas flow is upwards, which makes the gas flow blow molecular sieve from opposite direction, this may make molecular sieve …
