1, engaged in gas storage tanks and other pressure vessel equipment and other pipeline installation, transformation, maintenance must obtain the corresponding qualification license. Units engaged in installation must have installation qualifications, install in accordance with relevant safety specifications and requirements, and be responsible for the safety and quality of pressure vessels, and strictly implement national safety standards and technical standards.
2. The installation unit must provide installation qualification, installation drawings and installation plan. Repair unit must provide repair construction scheme
3, participate in major transformation and repair should be submitted to the special equipment safety management department, inform the relevant departments.
Major modification refers to changing the structure of the pressure vessel (pressure vessel) or operating technology and other parameters (including vessel, pressure, medium, etc.). And should go through the design drawings of departments and units with design qualifications. It also meets the safety standards of pressure vessels, and is familiar with some of the preparatory work and welding requirements of Gao in Qian. And after a series of manufacturing and testing process.
5. Fixed pressure vessels shall not be changed to mobile pressure vessels
6. The transformation of pressure vessels should also have the pressure test, water pressure test, flaw detection and other processes of pressure vessels.
7, the transformation of pressure vessels need to carry out pressure vessel thickness testing to meet the new requirements.
8. Major maintenance and transformation of pressure vessels must go through a series of inspection reports before the pressure vessel leaves the factory and some series of inspection reports and certificates issued by special equipment inspection.
The oil-free air compressor of the domestic brand has been officially produced in China for many years, and the products are also improving year by year. Companies that can do it in the industrial application scenario are also enriching cases. "Shanghai granklin group" water lubricated air compressor factory is one of the oil-free air compressor production factories. the production base is in Baoshan district of Shanghai. if you have any questions about the domestic oil-free air compressor, you can visit our factory at any time.
View detailsThe water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Therefore, the water-lubricated air compressor provides 100 percent oil-free clean compressed air. Product features: 1, high efficiency, reliability
Compressed air is ubiquitous in modern industry. Electronics, medicine, food, chemical and many other fields have high requirements for the quality of compressed air, requiring pure oil-free and dust-free compressed air. Water-jet screw oil-free air compressor is an emerging technology
Many people are familiar with air compressors, but it is not clear why a jar is used for what it is. The gas tank, as the name suggests, is a tank used to store gas. But its role is not only to store gas, the following is to give
The full name of the air compressor is the air compressor, which is the main body of the air source device. It is a device that converts the mechanical energy of the motor into gas pressure energy, and is a pressure generating device for compressed air. So how can the air compressor adjust the pressure? If the air compressor is adjusted
Compressed air can be pressurized, cooling, adsorption and other methods to remove the water vapor, and can be through heating, filtration, mechanical separation and other methods to remove liquid moisture. Refrigerated dryer is a kind of equipment that cools the compressed air to remove the water vapor contained in it and obtain relatively dry compressed air. The rear cooler of the air compressor also uses cooling to exclude the water vapor contained therein. Adsorption dryer is the use of adsorption principle to remove the water vapor contained in compressed air.
The water-lubricated oil-free air compressor produced by Shanghai Granklin Group adopts single-screw technology to replace oil with water to achieve lubrication, cooling, sealing, noise reduction and other effects, providing high-quality oil-free air, no pollution, and the discharged water No special treatment is required to meet environmental protection requirements.
With the blockade of China's high-tech technology and equipment by the United States in recent years, such as the recent mention of advanced technology and equipment used in the semiconductor and chip industries: Japan's Shin-Yue, the United States Dow, Asmai, etc. However, the realization of the semiconductor and chip industry's gradual national
We may not know, in fact, the maintenance of air compressor can be divided into four stages, according to the time node, is divided by day, month, quarter, year. Basically, the daily maintenance is to pay attention to check whether the exhaust port temperature of the host is abnormal.
For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free.
