Ultra high pressure seal with what material is better?

Ultra-high pressure sealing ring is a revolutionary product with metal structure, but it has all the properties of rubber sealing ring, but it can withstand multiple times of pressure, is wear-resistant and durable. Once installed, it will not be replaced if it is used permanently. It is extremely resistant to corrosion and extremely high temperature, and is easy to install and permanently guaranteed. The principle of ultra-high pressure sealing is not essentially different from that of medium and high pressure hydraulic components or hydraulic systems. It also uses seals to block fluid flow channels to prevent leakage and seal. For non-contact gap sealing, the gap channel with too long liquid flow is also used to receive resistance and generate pressure loss. The pressure difference to the gap outlet end is close to zero, and there is no leakage to form a seal.

Ultra-high pressure sealing ring, is a revolutionary product, metal structure, but has all the properties of rubber sealing ring, but can withstand multiple times the pressure, wear-resistant and durable, once installed, such as permanent use, no longer replaced, extremely corrosion-resistant and extremely high temperature-resistant, easy to install and permanent warranty. The principle of ultra-high pressure sealing is not essentially different from that of medium and high pressure hydraulic components or hydraulic systems. It also uses seals to block fluid flow channels to prevent leakage and seal. For non-contact gap sealing, the gap channel with too long liquid flow is also used to receive resistance and generate pressure loss. The pressure difference to the gap outlet end is close to zero, and there is no leakage to form a seal.

The difference between ultra-high pressure sealing ring and general pressure is that the material of the blocked seal must be able to withstand ultra-high pressure extrusion or impact; it is a gap seal, and its gap value is much smaller than the general pressure gap seal value.

Ultra-high pressure sealing ringFeatures: ultra-high, non-wear, high temperature resistance, low temperature resistance, corrosion resistance Working temperature:-200 0C ~ 900 0C Application: Replace rubber O-ring, more environmentally friendly, economical and lower cost.

The material of the ultra-high pressure seal requires its organization to be denser, to prevent leakage, and to prevent damage by extrusion, so it requires stronger. Generally, when the pressure of the liquid fluid medium exceeds 100MPa, it is difficult to use synthetic rubber, leather and fluoroplastics, while aluminum, copper, beryllium bronze and these non-ferrous metal alloys are used. These metals and alloys produce elastic-plastic deformation, which is beneficial to fill the concave and micro valleys on the uneven surface of the sealing surface.

In addition to the general requirements for sealing ring materials, the following conditions shall be noted for sealing rings:

(1) Flexible and resilient;

(2) Appropriate mechanical strength, including expansion strength, elongation and tear strength.

(3) Stable performance, not easy to swell in the medium, and small thermal shrinkage effect (Joule effect).

(4) easy processing molding, and can maintain precision size.

(5) does not corrode the contact surface, does not pollute the medium, etc.
