Gas storage tanks are commonly used industrial equipment for storing and purifying compressed air, and are also one of the special safety equipments that are strictly regulated by the state. In order to ensure safe and secure use, how will we choose and purchase safe and secure gas storage tanks?
First, design pressure and material selection
The design pressure meets the requirements, followed by the selection of materials to meet the requirements, and the thickness of the material can be reached. It is recommended that you do not only plan to be cheap when you choose. Low prices generally have the potential to cut corners. It is advisable to choose products that are produced by good credit manufacturers. There are many brands of gas tanks on the market today. Pressure vessels are generally designed with safety factors, pressure vessels are equipped with safety valves, and China's pressure vessel design standards are inherently more conservative than those of foreign countries. Therefore, in general, pressure vessels are Use is safe.
We should choose large-scale enterprises, well-known brands of products. The products of these companies not only strictly implement the national standards, but also form their own enterprise standards. At the same time, these enterprises have strict product production process management and use of good quality raw materials. Although these products may be relatively expensive, they can be used Guarantee the quality, use it to rest assured. In addition, through a variety of quality system certification companies, the products produced are also preferred.
Second, product appearance
The appearance of the product reflects the grade and value, only the formal and powerful manufacturers have advanced equipment, only 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 the gas tank can be clearly known 50 meters away from the gas tank. Approaching the gas storage tank, the tank itself is bright and bright, the surface is treated on average, and the weld line is smooth and clear. Therefore, it is best to purchase new products.
Third, the product nameplate
On the nameplate, the name of the manufacturer and the tester and the date of manufacture should be indicated. In the upper right corner of the nameplate, note whether there is a seal of the tester, and the nameplate must indicate the product's serial number, weight, volume, and tolerance. The maximum pressure and working pressure, as well as the pressure of the water pressure test, also need to 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. If the two inventions are inconsistent, please do not purchase it.
Fourth, quality assurance
According to the relevant regulations of the country, each gas tank factory must be equipped with a quality guarantee certificate. The quality guarantee certificate is the main document that proves that the gas storage tank is qualified. If there is no quality guarantee certificate, the gas tank, even if the price is lower, should be used in order to ensure its use. Safe, please the user is best not to buy.
Fifth, enterprise qualification
A powerful brand-name company does not have the qualifications and reputation that ordinary companies can match. Although some small companies have manufacturing licenses for pressure vessels, the overall equipment is obsolete and the management is not standardized. The gas storage tanks produced are prone to potential safety hazards. Therefore, users should be able to better understand the various aspects of the company's qualifications. In order to avoid unnecessary trouble. Afterwards, the manufacturer is requested to issue the inspection certificate issued by the local special equipment inspection office. The factory must also be checked by the special equipment supervision office where the company is located. The general air compressor discharge pressure is 7, 8, 10, and 13 kilograms. 7, 8 kg is the most extensive. Therefore, generally, one-seventh of the compressor's air volume is used as the selection standard for the storage tank capacity.
