Swelling and aging hydraulic seal

Imports of hydraulic acid Xinhua Xu rubber products seals Xinhua Xu rubber products importing acid and alkali resistance EPDM rubber seals, acid-resistant seals, alkali resistance seal in the trench initial deformation (interference) its sealing capability is very important:

1. The ability to obtain an initial sealing contact

2. Compensation product tolerance (both in connection with the clearance)

3. To ensure a certain degree of friction

4. Compensation compression set

5. Hydraulic seals compensate for wear

Hydraulic seal is a rubber element of the current oil and gas exploration is widely used, mainly in the device as a sealing member. Hydraulic Seals performance will primarily depend on the rubber material corrosion resistance in harsh corrosive environments.

At high temperature and pressure conditions of high levels of H2S and CO2, seal hydraulic seal failure mainly for swelling and aging rubber material, causing hydraulic seal shape changes, restitution, seals inelastic, seals and equipment resilient contact between stress is released, resulting in acid gas leak.
