I have been working in the field of cryogenic gas equipment for a long time, and I have seen many customers take detours when purchasing carbon dioxide storage tanks. They were so focused on bargaining that they ended up choosing those small workshops.Within less than half a year, the tank body began to frost and leak cold, the welds cracked, almost causing an accident. Later, they tried to contact the manufacturer but couldn’t reach anyone. Recently, many foreign manufacturing and food processing customers have come to me to ask how to find a reliable supplier of carbon dioxide storage tanks. Today, I will clearly explain my accumulated practical experience over the years, which is all the knowledge gained from experiencing the pitfalls.
First and foremost, we must ensure the qualifications. Don’t be swayed by the exaggerated claims made by the salespeople. A genuine pressure vessel manufacturing enterprise must obtain the A1/A2 level pressure vessel manufacturing license, the special equipment manufacturing supervision inspection certificate, and the ISO9001 quality system certification simultaneously. All these qualifications can be found on the official website of the China Market Supervision Administration. Even if any one of them is missing, we cannot proceed. Previously, a client saved two thousand yuan by choosing an unqualified small factory. However, the equipment was immediately inspected by the safety supervision department and was directly ordered to be scrapped. The loss ended up doubling.
The second point is that you should not just rely on the quotations. You must also visit the production site to inspect the production process. Reliable manufacturers will use genuine national standard steel materials. Each batch of raw materials can provide an origin traceability report. The welding process is safe and reliable. All Class A and B weld seams are 100% subjected to radiographic testing. The entire vehicle body has undergone heat treatment, which can eliminate the stress caused by welding. Before leaving the factory, a water pressure test is also conducted. The pressure must reach 1.5 times the design pressure and last for 30 minutes. The pressure drop during the test must comply with national standards and cannot be ambiguous. Some small factories, in an attempt to save money, use substandard thin steel plates and even let the workers weld them directly. X-ray testing? It is simply not done.Within two years, they are prone to leakage points, and even have the risk of cracking at low temperatures.
The third point is to pay close attention to the detailed configuration and after-sales guarantee. A qualified carbon dioxide storage tank must be equipped with a vacuum gauge and a vacuum valve. Later, it can be used to detect the vacuum level of the inner layer at any time. The safety valve should be configured in two paths, and during the calibration process, the entire tank does not need to be shut down for pressure relief. A reliable supplier will not simply disappear once their products are sold out. They offer on-site installation guidance, remind about maintenance every three years, respond to faults within 24 hours, and will never shirk responsibility when problems occur.
When purchasing carbon dioxide storage tanks, customers should not solely rely on price when choosing a supplier. Instead, it is necessary to look for manufacturers that have physical production facilities. This way, you can visit the production line in person and receive prompt maintenance responses. In case of any problems, they can be resolved promptly. As it is a special type of equipment, safety always comes first. Spending more time on research is much more important than saving a few thousand dollars.
