Answer: Every 4 years. Question: When should special equipment be registered with the local quality supervision department? Answer: Within 30 days before or after the special equipment is put into use. Question: Within how much time before the expiration of the valid period for the safety inspection of special equipment, should an application for a regular inspection be submitted to the special equipment inspection agency? Answer: 1 month. Question: What procedures must be followed when special equipment is not in use or is scrapped and removed? Answer: An application should be submitted to the local quality supervision department to suspend or cancel it. Question: How can special equipment that has been taken out of use be put back into operation? Answer: It must be reported to the local geological supervision department, and can only be put into use after passing the inspection. Question: What should be indicated by a red line on the dial of a pressure gauge? Answer: It indicates the maximum allowable operating pressure. Question: How to ensure that the water level gauge remains unobstructed and prevent false water levels from forming? Answer: The water level gauge should be flushed once per shift, and any leaks in the steam and water cocks of the water level gauge must be fixed. Question: It has been found that the boiler in operation is low on water – can water be added urgently? Answer: Water cannot be added; the furnace must be shut down immediately. Question: How to shut down the furnace urgently? Answer: Stop supplying fuel and stop air supply, remove or scoop out the fuel from inside the furnace, so that the boiler cools down gradually. Question: How to perform emergency venting after an emergency shutdown of the furnace? Answer: Close the main steam valve to isolate the boiler from the main steam pipe ； Gradually exhaust air outward through the safety valve or emergency vent to reduce the air pressure. Question: How to prevent the safety valve disc from rusting? Answer: Manual or automatic venting tests should be carried out regularly. Question: How many types are there for the regular inspection of pressure vessels? Answer: It includes a comprehensive visual inspection and a pressure resistance test. Question: What should be done in an emergency when it is necessary to stop operation? Answer: First, quickly cut off the power supply and stop the material transfer ； Then quickly open the outlet valve to release the gas or material, and open the vent valve if necessary. Question: What should be checked before starting the operation? Answer: Check whether the air pump, air tank, pipes, valves, and safety accessories are in good condition. Question: Can the maximum operating pressure of a pressure vessel during use be higher than the design pressure? Answer: No, it’s not allowed. Question: What should be noted when the container starts to be pressurized? Answer: The speed should not be too fast to prevent a sudden increase in pressure. Question: Can the compression bolts be removed under pressure? Answer: No, it is not possible; the pump must be stopped, and air must be removed to relieve pressure before proceeding. Question: What is the position of the pressure gauge pointer when there is no pressure? The response should be at the limit pin or back to the zero value. Question: Why is safety monitoring carried out on it? Answer: Boilers, pressure vessels, and pressure pipelines are special types of equipment with explosion hazards that are widely used in production and daily life. Question: What are the oversight systems? Answer: The design, manufacturing, installation, maintenance, and modification of special equipment must be carried out in accordance with the Regulations on the Safety Supervision of Special Equipment; relevant activities can only be undertaken after obtaining a license as required by law.
