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

The ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.
The spring energized seal is a high-performance Teflon seal with a special spring inside.
The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.
JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
S-Seal is designed for extreme oil and gas applications. It is a technologically advanced replacement for traditional three-piece T-Seals or O-Rings with back-ups.
V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
