LNG nozzle spring energized seals manufacturer


LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns. Currently, it can be equipped with the most brand of filling guns and filling nozzles, both Chinese and overseas.


Main material:

Imported polymer material. It is reinforced for ultra-low temperature environment, and the lip is specially grinded, making it more wear-resistant and longer in service life.


Spring:

Adopt alloy+special treatment process (reduce metal transformation deformation of metal spring at low temperature, and improve yield strength) The special spring is made of HEATTREATED ELGILOY alloy spring. Compared with ordinary stainless steel spring, it is very stable in physical system at low temperature, with high spring load, it can maintain good sealing effect at low temperature, low pressure or when the surface finish is not ideal; Suitable for static and slow dynamic sealing.



Advantages:

1. Mature spring yield strength improvement process
2. Fatigue test ≥ 2000 times (low temperature of liquid nitrogen)
3. Good dynamic and static sealing
4. Chemical resistance
5. Low friction coefficient, effective wear reduction, self-lubricating, very good dry friction characteristics
6. Anti aging, without permanent elastic deformation
7. Anti aging, no permanent elastic deformation, greatly improving sealing capacity and service life

Cryogenic valve seals

In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
