Oil Well Device S-Seals material characteristics (NBR Materials)
1. High-temperature resistance: The skeleton oil seal has good high-temperature resistance.
2. Oil resistance: It can resist hydraulic oil, diesel oil, engine oil, gasoline, lubricating oil, etc.
3. Strong tear resistance and good bending strength.
4. High tensile strength and elongation at break.
5. Low compression set rate.
Oil Well Device S-Seals are mostly used in high-pressure environments, such as static seals with pressures greater than 10,000 psi, and are widely used in wellheads and downhole tools in the oil and gas industry. The standard size is based on the O-ring AS568 standard groove size, and can also be designed according to customer requirements.
Of particular note, Oil Well Device S-Seals are designed for harsh oil and gas applications, particularly the high-pressure and high-temperature environments involved in downhole, subsea, and wellhead equipment.
Sealing principle
S-Seals in oil well devices are sealing elements whose sealing principle uses elastic deformation and sealing shear force to achieve effective sealing.
S-type seals are usually made of elastic materials such as rubber or polymer. They have a special S-shaped cross-section design with an S-shaped cross-section. This design allows the seal to generate sealing shear when compressed and form an effective seal on the sealing surface.
1. Compression deformation: When the S-shaped sealing ring is assembled into the sealing groove or sealing seat, it will be subject to compression force due to its small inner diameter. This compressive force causes the cross-section of the sealing ring to deform, causing it to come into close contact with the sealing surface.
2. Sealing shear force: Due to the S-shaped cross-section of the S-shaped sealing ring, the upper and lower parts of the sealing ring generate relative shearing forces. This shear force creates a tight sealing interface between the sealing ring and the sealing surface, preventing liquid or gas leakage.
3. Elastic recovery: S-shaped seals have good elasticity. When the pressure is reduced or removed, the sealing ring returns to its original shape. This elastic restoring force helps maintain close contact between the sealing ring and the sealing surface and ensures sealing reliability.
