SONKIT metal seal rings have a wide range of application cases in melt filters, conveying pipelines and spinning blowing equipment.



SONKIT metal sealing ring, compared with the solid sealing ring used in traditional  equipment, the outstanding feature is that due to the special hollow structure, the SONKIT sealing ring is easier to compress and deform, and because of the proper installation groove design, the metal O-Ring, with rare rebound, in fluctuating temperature or pressure conditions, compared to solid metal sealing ring, the sealing effect of SONKIT metal sealing ringis safer and more reliable.

 

Chemical fiber application case:

 
SONKIT has extensive and long-term cooperation experience with melt filter equipment manufacturers and chemical fiber manufacturers.
 
For chemical fiber equipment, balanced metal hollow O-rings are generally used. The base material of metal O-rings is 316L/321 stainless steel, the most common, and the coating material is generally silver-plated.
 

Working condition characteristics:

 
High temperature: about 400℃, high pressure: 40Mpa, medium: chemical fiber melt.
