With the development of the LNG liquefied natural gas industry in recent years, the domestic market for LNG liquefied natural gas has become increasingly common. Our company has been in the sealing industry for 8 years and has our own professional research and technical team. After years of experience accumulation and exploration, we have collected valuable feedback from major gas stations and distributors. Through visits to major gas stations and face-to-face conversations with customers, we have found that there are still significant deficiencies and shortcomings in domestic LNG sealing rings. Our company has solved structural problems such as the design of the sealing lip being too thick and lacking in elasticity in old-fashioned gas filling seals. Introducing foreign technology and adopting imported springs, we will conduct research and development on new products such as spring welding technology. Currently, the new products have been launched, which will enable them to quickly enter the market at a reasonable price. The product quality has passed layers of testing and has been verified by multiple customers in different regions. The feedback is quite good, and both domestic and imported liquid additives can be used interchangeably.

Product Features:

Mature spring yield strength enhancement process

- Fatigue test ≥ 6000 times (liquid nitrogen low temperature)

- Good dynamic and static sealing

- Chemical corrosion resistance

- Low friction coefficient, effectively reducing wear, self-lubricating, very good dry friction characteristics

- Anti aging, no longer elastic deformation

- Pressure: ≤ 3.45MPa

- Temperature: -200 ℃~100 ℃

- Anti aging, no longer elastic deformation, greatly improving sealing capacity and service life

Our company focuses on the research of materials, and the developed materials have good chemical corrosion resistance and a wide temperature range. There are currently 13 types of materials developed and applied in the low-temperature materials industry. It can have wear resistance, pressure resistance, and chemical corrosion resistance in low temperature environments, thereby improving the overall sealing performance of the seal
