RTJ gaskets in the sealing ring industry, elliptical gaskets are relatively common.
The elliptical ring needs to be cleaned before use, after maintenance, and during storage, and its necessity is mainly based on the maintenance of sealing performance and corrosion protection considerations.
One possibility is that before the first installation, there may be rust proof oil, cutting fluid residue, or transportation dust on the surface of the new elliptical ring. Direct installation may cause contamination of the sealing surface, and it needs to be thoroughly wiped with acetone or ethanol.
One is the elliptical gasket that has been in contact with corrosive media (such as acid, alkali) or high-temperature oil stains after maintenance and disassembly. Coking and metal debris need to be removed, otherwise repeated use may cause seal failure.
One is that after long-term storage, moisture or organic matter may be adsorbed in the warehouse environment (such as infiltration of packaging oil paper), and cleaning is required before installation to avoid corrosion of the sealing surface.
The steps for cleaning are as follows:
1.Preliminary treatment: Use a soft cloth to physically remove large particle impurities.
2.Solvent immersion: Soak the gasket in cleaning agent for ≤ 10 minutes (too long can cause swelling).
3.Ultrasonic enhancement: Clean complex structural gaskets with 40kHz ultrasonic waves for 5 minutes.
4.Neutralization rinsing: After acid/alkali cleaning, rinse with pure water until pH is neutral.
5.Dry storage: After drying with compressed air, apply light rust proof oil and store in a dry container.
Regular and standardized cleaning can extend the sealing life of elliptical gaskets, but it is necessary to strictly follow the principle of material compatibility to avoid functional damage caused by excessive cleaning!
There are many series of ring joint gasket, including R gasket, RX gasket, BX gasket, IX gasket, SBX gasket, etc. More information is waiting to be shared.
