Lack of regular maintenance of metal ring gaskets can lead to serious safety hazards and property damage.
The consequences are as follows:
1. Sealing failure leads to leakage
Deformation not detected: Metal ring gaskets are prone to permanent deformation under long-term pressure, and if not regularly inspected, they will lose their sealing function, increasing the risk of high-pressure pipeline leakage by 200%; The medium leakage rate at the flange connection can reach 15L/min (under oil and gas conditions).
Corrosion exacerbates failure: residual chemical media (such as acid) corrode the sealing surface of the gasket, causing pitting or cracks, and the sealing pressure drops by 40%; The stress corrosion cracking rate in chloride ion environment is increased by three times.
2. Equipment chain damage
Damage to the flange sealing surface: Local stress concentration on the deformed gasket causes the flange sealing surface to crush or scratch (depth>0.2mm); The repair cost is 20 times higher than replacing the gasket (requiring re turning of the flange).
Production system paralysis:
Emergency shutdown: loss of ¥ 50000+per hour;
Media pollution: The entire batch of products is scrapped.
3. Security and maintenance costs skyrocket
Explosion and poisoning accidents: Explosion caused by flammable medium leakage encountering open flames (case: flange leakage in a chemical plant causing serious injuries to 3 people); Toxic gas (hydrogen sulfide, chlorine) leakage exceeds the standard by 10 times
Maintenance cost doubled: forced replacement cycle shortened by 50% (normal maintenance life of 10 years → no maintenance only 5 years); The cost of major repairs is 15 times higher than the cost of regular maintenance.
Therefore, regular maintenance is very important.
There are many types of RTJ gaskets, including R Gasket,RX Gasket,BX Gasket, SBX Gasket,IX Gasket,flange connections,and various customized products.We will do more sharing about ring joint gasket.
