There are many brands of gas tanks in the market today. Because the safety factor of such products is very high, it plays a vital role in the selection of gas tanks in order to ensure their safe and secure use. Now, how to choose and buy safe and secure gas tanks will be briefly explained as follows:
First, products from large enterprises and well-known brands should be selected. The products of these enterprises not only strictly implement the GB15-98 Standard for Steel Pressure Vessels, but also form their own enterprise standards. At the same time, the products of these enterprises have advanced production equipment, strict production process management and good quality raw materials. Although the products of these enterprises may be relatively expensive, they can guarantee the products when they are used, and they can be used with confidence. In addition, products produced by enterprises that have passed various quality system certifications are also the first choice.
the second is the appearance. The appearance of a product reflects its grade and value. Only formal and powerful manufacturers have advanced equipment guarantee and good quality guarantee system to ensure the grade of the product appearance. The trademark of a good quality gas storage tank is very obvious, and the brand of the gas storage tank can be clearly known 5 meters away from the gas storage tank. Approaching the gas storage tank, the tank itself has bright color, uniform surface treatment, flat weld and clear lines, so it is best to buy new products.
third, look at the product nameplate. The name and date of production of the manufacturer and the supervision and inspection unit shall be indicated on the nameplate, and whether there is the seal of the supervision and inspection unit in the upper right corner of the nameplate. In addition, the nameplate must indicate the product number, weight, volume, maximum pressure and working pressure, as well as the pressure of water pressure test, and also indicate the medium of the gas storage tank. There must be a steel seal number of the product directly below the nameplate of the whole tank, and the steel seal number must be consistent with the number on the nameplate. If the two numbers are found to be inconsistent,
the fourth is to look at the quality guarantee. According to the relevant regulations of the state, each gas storage tank must be provided with a quality guarantee, which is an important document to prove that the gas storage tank is qualified. If there is no quality guarantee, even if the gas storage tank is cheap, in order to ensure the safety of use, users are advised not to buy it.
the fifth is to look at the qualifications of manufacturing enterprises. A powerful brand-name enterprise has qualifications and honors that are not comparable to those of ordinary enterprises. Although some small enterprises have manufacturing licenses for pressure vessels, the overall equipment is outdated and the management is not very standardized, and the gas storage tanks produced are prone to potential safety hazards. Therefore, it is best for ordinary users to have a more comprehensive understanding of the qualifications of the enterprises in order to avoid unnecessary troubles.
Brief introduction of gasholder:
Gasholder is an industrial equipment commonly used in industry to purify and compress air, and it is also one of the special safety equipment strictly supervised by the state. Gas storage tanks are pressure vessels, which are produced by the designated factory of pressure vessels, and each one is provided with container inspection certificate and accessories such as safety valve, blowdown valve and pressure gauge.
gasholder function:
gasholders can be used in parallel or in combination with a single one; Can weaken the airflow pulsation discharged by the piston air compressor; Improve the continuity and pressure stability of the output airflow; Further precipitation and separation of water and oil in compressed air; Ensure continuous supply of sufficient gas. It can be used in parallel or in a single unit.
principle of gasholder:
water-the relative humidity in the atmosphere is generally as high as 65% or more. After compression and condensation, it becomes wet saturated air, with a large number of liquid water droplets, which are the fundamental reasons for the corrosion of equipment, pipelines and valves. In winter, freezing will also block the small hole channels in the pneumatic system. It is worth noting that even if it is separated from pure saturated air, with the decrease of temperature, there will still be condensed water, and its saturated water content will decrease by 5% for every 1℃ decrease, that is, half of the water vapor will be converted into liquid water droplets (see Table 1). Therefore, it is necessary to use multi-stage separation and filtration device in compressed air system or to pretreat compressed air into dry air with certain relative humidity.
