Spiral Wound Gasket

Spiral Wound Gasket

One of the widely used seals, the spiral wound gasket depends on the mechanical characteristics of a formed metal strip which works as a spring, offering a better resilience under fluctuated pressure & temperature.

R Type Spiral Wound Gasket : 
SWG with only filler and winding,   suitable  for  high  pressure  and  temperature  applications for TG/male/ female   flange . 
For example: SS304/FG.

CGI Type Spiral Wound Gasket:  
SWG with inner and outer ring,  for raised  & flat face flange.
For example: SS304/SS304+FG/CS

CG Type Spiral Wound Gasket:  
SWG with only outer ring, for raised / flat face flange.
For example: SS304/FG CS

RIR Type Spiral Wound Gasket:
SWG with only inner ring,  for  male  / female   flange. 
For  example:  SS304/SS304/FG

H Type Spiral Wound Gasket:
SWG for heat exchanger.
For example: SS304/FG with 1 bar of DJ 

S Type Spiral Wound Gasket:
Special shape for special flange/ for example: track, oval, diamond, square

How to choose Filler
The main sealing part is filler which is made up of SS strip and non- metallic filling tape,  the  material can be changed  according to different chemical compatibility requirements, 
Graphite filling strip is supposed to used in high temperature environment,  
PTFE filling  strip is for acids and other corrosive mediums 
Non – asbestos   its use increased when the health problems with asbestos became  known. Only  recommend  for low temperature less severe applications due to the rubber content . 
Ceramic is in extremely high temperature applications.The filler is not so common as it cannot achieve the same leak tightness as graphite  
Marking (standard): 
Marking on outer ring: 
– Manufacturer
– Nominal Size – Pressure Range 
– Winding material + Filler Material 
– Manufactured  to (standard)

We deliver according to the following standards: ASME B16.20, ASME  B16.47 Series A, ANSI B16.5, BS1560, BS EN1092, DIN, JIS , etc. 
How to order
1 — Nominal pipe size or specific gasket dimensions
2 — Pressure rating
3 — winding and filler materials
4 — centering / outer ring or inner ring material
