Liquid Thread Seal Tape Series

Typical Applications:  

The anaerobic pipeline thread sealants made of PTFE is widely used on the installation of galvanized malleable iron pipe fittings, such as central air-conditioning system, gas pipelines, extinguishing pipelines, air compressor, water and heat supply pipelines. A technical resolution is required to solve the pipe thread sealing challenge. The third generation LT150 is not only used for sealing pipe threads but also flange faces. The performance is superior to the traditional solid gasket seal, such as asbestos pads, rubber pads and etc. The thickness has been increased from 0.25mm to 0.5mm. Easy to maintain and disassemble.

Remarks:

For stainless steel alloy materials, please contact at our sales department for more information about Litai 577, which is specialized for stainless steel pipe threads.

Features:

(1) It has passed the pressure and temperature tests by National Chemical Building Materials Testing Center, and water quality and safety tests by Guangdong Disease Control and Prevention Center, and acquired ROHS certificated issued by SGS and CE certificate. It causes no pollution to the environment and water supply.

(2) It is very stable. At the room temperature, it is not volatile or solidified. It can be used for sealing threads of low precision and incomplete threads. The superfluous sealant is easy to clean up, and thespilled sealant will not be solidified, easy to clean up, which does not bring harmful impact to the appearance of the facilities and equipments.

(3) During assembly, the angle of the pipe fitting can be adjusted at will without affecting the sealing performance. The sealant does not contain any solvent or shrink. Once fully cured, it will swell a littlebit, and fill the clearance completely so as to achieve better sealing and locking performance. The sealing pressure can reach up to 30Mpa and above.

(4) Aging resistance, corrosion resistance, acid and alkali resistance, resistant to the majority of medium, preventing the thread surfaces from rusting, strong weather resistance and vibration resistance

(5) It is easy to disassemble. For a normal sized pipe fitting, it can be disassembled with a wrench or hands. For a large pipe fitting, it is recommended to heat it up with an oxy-fuel thermal spray gun before disassembly. The pipe joints can be reused after cleaned up.  

(6) Low overall costs, easy to operate and install, coating the threads directly, dramatically improving working efficiency
