Learn More about Spring Seals: Materials, Structure and Performance

PTFE SEALING GASKET SELF LUBRIATE

Spring sealing ring is a kind of seal widely used in various industrial fields. It has corrosion resistance, high elasticity and good sealing performance. This blog will delve into the material, structure and performance of spring seals to help you better understand this important sealing component.

1. Material of spring seal ring
Spring sealing rings are mainly made of metal and non-metal materials. Metal materials include stainless steel, copper, nickel, etc., which have good corrosion resistance and thermal conductivity, and are suitable for high temperature and high pressure environments. Non-metallic materials mainly include polymers, rubber, etc., which have good elasticity and wear resistance and are suitable for corrosive environments and low friction requirements.

Stainless steel spring seal
Stainless steel is a metal material with excellent corrosion resistance, so it is often used to make spring seals. Stainless steel spring seals have high strength and hardness, can withstand high pressure and high temperature environments, and have good elasticity and durability.

Polymer spring seal
Polymer is a non-metallic material with good elasticity and wear resistance, suitable for corrosive environments and low friction requirements. The main advantages of polymer spring seals are low price, easy processing and installation, and good corrosion resistance and wear resistance.

2. Structure of spring seal ring
The structure of the spring seal ring usually consists of a polymer material sealing shell and a stainless steel metal spring. This structure makes the spring seal ring have good elasticity and corrosion resistance, and can adapt to various complex environmental conditions.

Polymer sealing shell
The polymer sealing shell is the outer structure of the spring sealing ring, which mainly protects the spring and prevents contaminants from entering. Polymer material sealing shells are usually made of polymer materials, such as polytetrafluoroethylene (PTFE), polyurethane (PU), etc. These materials have good wear resistance and corrosion resistance and can adapt to various complex environmental conditions.

stainless steel metal spring
The stainless steel metal spring is the core structure of the spring seal ring, which provides elasticity and adapts to various deformations. Stainless steel metal springs are usually precision machined, have high strength and hardness, and can withstand high pressure and high temperature environments. At the same time, stainless steel metal springs also have good corrosion resistance and durability, which can ensure the long-term stable operation of the spring seal.

3. Performance of spring seal ring
The properties of spring seals mainly include corrosion resistance, high elasticity, wear resistance and high temperature resistance. These properties enable the spring seal ring to maintain a stable sealing effect under various complex environmental conditions.

Corrosion resistance
The corrosion resistance of spring seals is one of their most important properties. In environments such as acid and alkali solutions, corrosive gases and liquids, spring seals can maintain stable performance and prevent leakage and damage.

High elasticity
The high elasticity of the spring seal is one of its unique properties. Under the condition of withstanding high pressure and impact, the spring seal ring can adapt to various deformations and pressure fluctuations and maintain a stable sealing effect.

Wear resistance
The wear resistance of spring sealing rings is one of its important properties. Spring seals maintain long-term stability and performance despite friction and wear.
