Heptafluoropropane is the best-selling and mainstream gas fire extinguishing equipment in the domestic gas fire extinguishing market. Because of its powerful fire extinguishing performance and excellent product characteristics, it is widely praised by customers in the market. Today, let's explain in detail the ways of heptafluoropropane.
You should know that the general storage time of heptafluoropropane fire extinguishing system is 5 years, during which we need to carry out detailed maintenance of the equipment, but in case of any accident halfway, I will contact a professional recycling manufacturer to recycle the equipment and scrap the damaged devices. In this process, we can't repair the equipment without permission, which is also to ensure people's safety. What kind of treatment will our professional recycling manufacturer do to him when recycling heptafluoropropane fire extinguishing system? Now let's take a look at the disposal of heptafluoropropane fire extinguishing system!
We need to know the detection and filling of heptafluoropropane.
Heptafluoropropane fire extinguishing system looks very complex, but in fact, the later detection and filling are not complicated. Whether there is pipe network or cabinet type, the equipment can be disassembled under the guidance of professional manufacturers or technicians, and the steel cylinder and cylinder valve components (including siphon, container valve, etc.) can be handed over to the manufacturer for detection and filling.

In general, if the pressure of the pressure gauge is normal, the steel cylinder has no obvious damage, which affects the quality of reagent filling, and other parts can be used normally after disassembly and cleaning, it is recommended that the customer test and fill the heptafluoropropane fire extinguishing system.
Secondly, let's see what factors will cause the system to need to be replaced.
1. If the pressure gauge is abnormal and the steel cylinder and other parts are highly depreciated, the normal use of the system cannot be restored through detection, filling, disassembly and cleaning. In this case, the manufacturer will recommend the customer to replace the system for the sake of safety.
2. The pressure gauge is normal (or abnormal) and the steel cylinder has no obvious problems, but the depreciation of other parts of the system is large, and some important parts will not be able to restore the normal fire-fighting function of the original system after exiting the market, so we can only choose to replace the new system.
3. For safety reasons, some local fire inspection departments will also require users to test, fill and replace new parts of heptafluoropropane systems that have been used for a long time. In this case, the cost of testing, filling and replacing parts is not very different from that of replacing a whole set of new ones. Some customers prefer to simply replace the new system.
When the purchased heptafluoropropane system has been used for a long time, and it is found that there is insufficient pressure and other conditions that obviously affect the fire-extinguishing function during daily inspection, it is necessary to contact professional manufacturers immediately for treatment. If the system is normal and replaced or refilled for safety reasons, you can first contact the fire detection organization for detection to determine whether to contact a professional manufacturer for treatment.
Steel cylinders shall be scrapped under the following conditions:
1. Cylinders with ambiguous steel seals or incomplete key items and no evidence to check shall not be filled and shall be scrapped.
2. Gas cylinders with loose neck rings that cannot be reinforced or replaced, and gas cylinders with original neck rings reinforced by welding methods shall be discarded.
3. Cylinders with cracks on the screw thread at the mouth shall be scrapped.
4. Cylinders with visible cracks on the cylinder body shall be scrapped.

5. Cylinders with arc scars, welds or deformation caused by fire shall be scrapped.
6. Cylinders with concave convex defects and a depth of more than 2mm shall be scrapped.
7. Cylinders with heavy and short sound and shell breaking sound shall be scrapped.
8. If the internal and external surfaces of the gas cylinder are seriously corroded, if the area exceeds 20% and the depth exceeds 20% of the original wall thickness, it shall be scrapped.
9. Cylinders whose current weight is less than the marked weight and the difference is greater than 5% shall be scrapped.
10. Gas cylinders whose current volume is greater than 10% of the marked volume shall be scrapped.
11. Cylinders with a service life of more than 30 years shall be scrapped.
