After the recommended service life of the gas storage tank expires, if the data and certificates are still complete, go directly to the local special equipment inspection department to submit the data certificate for inspection. If the inspection result is qualified, it can continue to be used. Scrap and buy a new one. What I want to say here is that the verification must be carried out every year after the expiration, and whether it can continue to be used is determined according to the result of the verification. It has expired and I plan to continue to use it. The data is no longer available. In this case, it is recommended to scrap it and buy a new one, because it is impossible to confirm whether the gas storage tank is qualified or not, and there is a potential safety hazard to continue using it. In response to this answer, many users will say: the jar is good, how can it be scrapped, send a copy of the provided information, and check if it is not good; some users even thought of sending the information of the new jar directly Can't you just test one? It is a pity that the answer is that this information certificate is an after-sale document, which is not archived by the manufacturer, and the re-approval has to be re-applied at the third-party quality supervision bureau. , after the expiration date, the information will be completely destroyed, so this information cannot be provided. When it comes to replacing the old jars with the new jars for inspection, this is impossible, because a jar corresponds to a data certificate and nameplate, and cannot be used instead of other jars, such as one person and one ID card. The same is true, so it is absolutely impossible to replace this method.
