The gas tank is an industrial equipment commonly used in industry to purify and shrink air, and is also one of the special safety equipments that the country strictly supervises.
First, the design pressure meets the requirements, followed by the selection of materials to meet the requirements, the thickness of the material can be achieved on the request. The proposed choice not to only map the price, the lower the price of the general will have the opportunity to cut corners, of course, recommend the selection of some credit manufacturers to produce products, I recently met with a certain brand of gas tanks in local factories. When they were reviewed by the relevant departments, they found that their thickness was about 0.5 mm. Nowadays, the brand of gas tanks on the market is very complicated. In general, pressure vessels are designed with safety factors. Pressure vessels are also equipped with safety valves that reflect each year. Moreover, China's pressure vessel design standards are inherently more conservative than those of foreign countries. Therefore, pressure vessels are generally safe to use. Under the same pressure level, the same medium, and the same working conditions, the thickness of foreign pressure vessels is smaller than that of the domestic ones. Screw air compressors. This is also because of the superiority of its steel plate function and the soundness of the safety supervision system. Because of the high requirements on the safety factor of such products, in order to ensure safe and reliable use, the selection of gas cylinders is of primary importance. How to choose and purchase safe and reliable gas cylinders will now be adopted. The following is a brief explanation:
First of all, we should choose products from large companies and famous brands. The products of these companies not only strictly enforce the standards of GB150-98 “Steel Pressure Vesselsâ€, but also form their own enterprise standards. At the same time, the production equipment of these enterprises advances their predecessors, the management of production processes is strict, and the quality of the original materials used is of good quality. Although the prices of these products may be relatively expensive, they can be used to ensure the products and use them with confidence. In addition, the products produced by companies that have passed a variety of quality system certifications are also preferred.
The second is the appearance. The appearance of the product reflects one of its grades and values. Only formal and powerful manufacturers have advanced equipment guarantees and a good quality assurance system to ensure the appearance of the product. A trademark of a well-known gas tank is very obvious, and the brand of gas tank can be clearly known 50 meters away from the gas tank. Approaching the gas storage tank, the tank itself has bright color, average surface treatment, smooth weld line, clear lines, so it is best to buy new products.
The third is to look at the product nameplate. The name and production date of the production company and the supervisory inspection unit shall be stated on the nameplate. Whether there is a seal of the supervisory inspection unit in the upper right corner of the nameplate, and the number, weight, size, and weight of the product must be stated on the nameplate. The pressure of the highest pressure and working pressure and the pressure of the water pressure test must also indicate the medium of the gas tank. There must be a product's stencil number just below the nameplate of the tank, and the stencil number and the number on the nameplate must be the same. The two numbers of the invention are inconsistent. Please do not purchase it.
The fourth is to look at the quality guarantee. According to the national demarcation, each gas tank factory must be equipped with a quality guarantee certificate, and the quality guarantee certificate is the main certificate for the gas tank approval. If there is no quality guarantee certificate, even if the price of the gas tank is low, but in order to To ensure safe use, please do not buy it.
Fifth, we hope to produce the qualification of the company. A powerful brand-name company has the qualifications and reputation not comparable to ordinary and ordinary companies. Although some small businesses have permission to manufacture pressure vessels, the overall equipment is obsolete, management is not very standardized, and the produced gas tanks are prone to safety hazards. Therefore, it is better for the general users to purchase and better understand the overall situation. All aspects of the company's qualifications to avoid unnecessary trouble. After you request the manufacturer to issue the inspection certificate of the local special equipment inspection office, you must also ask the company's special equipment supervision office to re-inspect the factory. The general air compressor discharge pressure is 7, 8, 10, and 13 kilograms. Among them, 7-8 kg is the most extensive. Therefore, it is generally taken as 1/7 of the compressor gas volume as the selection criteria for the tank capacity.
