Use of Sealing Rings
1. Before installing the sealing ring, check whether the specifications of the sealing ring and guide block are correct, whether the guide block is complete, and whether there is any looseness.
2. Check whether the sealing head groove is clean, free of iron filings, gravel, oil stains, scratches, rust, protrusions, and pits.
3. Before installation, use a clean cloth to clean the sealing groove, and evenly apply an appropriate amount of grease on the groove surface for lubrication, to facilitate the return after pressure testing.
4. The surface of the sealing ring should be cleaned before installation, apply an appropriate amount of grease to the lip and both sides, and then install.
5. During installation, ensure that the guide block faces the direction of the steel pipe inlet, and avoid incorrect installation.
6. After installing the sealing head, pressure test it several times to ensure the sealing ring performs optimally; avoid pressure testing with an empty pipe or with the steel pipe not fully inserted.
Storage of Sealing Rings
Sealing rings should be placed on shelves that are shielded from light, dry, and well-ventilated. Prolonged exposure to strong light will gradually cause the surface color of the sealing ring to turn yellow or dark red; in a humid environment, the sealing ring may mold, produce mildew, and its mechanical strength will quickly decrease.
Little Knowledge
1. Placing the sealing ring for a period of time improves its performance and usage effect.
2. The hardness of the sealing ring softens in summer, and its size expands; in winter, it hardens and its size shrinks.
3. Before using the sealing ring in winter, it can be placed in a warm indoor area or on a heater for a while to soften it.
4. When the surface of the sealing ring appears light yellow or dark red, its usage effect is better.
5. The correct storage lifespan of a sealing ring is generally 2-5 years.
