Rubber seals Affected by various external environmental factors, we need to pay attention to the surrounding environmental conditions during storage.

1. Temperature: 5-25 ℃ is the ideal storage temperature. Avoid contact with heat source and sunlight. Seals taken out from low temperature storage should be placed at 20 ℃ before use.

2. Humidity: The relative humidity of the warehouse should be less than 70% to avoid excessive humidity or dryness, and condensation is not allowed.

3. Lighting: avoid sunlight and strong artificial light source containing ultraviolet ray. UV resistant packaging can provide good protection. It is recommended that the windows of the warehouse be painted with red or orange paint or pasted with film.

4. Oxygen and ozone: The rubber material shall not be exposed to the circulating air. This can be achieved by packaging, winding, storing in airtight containers or other suitable methods. Ozone is harmful to most elastomers. The following equipment shall be avoided in the warehouse: mercury vapor lamp, high-voltage electrical equipment, motor and other equipment.

The creep resistance of rubber seals shall be good under the influence of pressure load and operating temperature, otherwise it will result in the loss of bolt torque, which will reduce the external stress of rubber seals, and then the hard gas system will leak. Rubber seals selected for chemical corrosion resistance of rubber seals shall not be corroded by chemical media and shall not pollute the media. Resilience of rubber seals Even if the system is stable, the two connected flanges will surely have slight displacement due to the influence of temperature and pressure. The elastic function of rubber seals should be able to compensate for this displacement to ensure the tightness of the system.
