-:: SPIRAL WOUND GASKETS ::-


SPIRAL SEAL Gaskets are made of Alternate piles of preformed Metal and soft Non-Metallic Filler. The Metal winding of the Spiral Seal is formed in to CHEVRON configuration [> shape] allowing Superior Resiliency and Self Adjustment compare to convential Gaskets, which enables Spiral Seal gasket to adjust automatically to change in operating condition such as,


> FLUCTUATING PRESSURE & TEMPERATURE.
> THERMAL EXPANSION OR CONTRACTION
> FREQUENT OR SUDDEN VIBRATION
> MINOR FLANGE SEPARATION
> JOINT RELAXATION


It works in almost all known Corrosive and Toxic condition and environment with suitable combination of winding and filler material.

 

Installation of Spiral Gaskets is very quick and simple. Spiral Seal Gaskets does not require special flange finish and it can be used where flange are mis-aligne or pitted.


Spiral Seal Gaskets compression depends upon density of Winding which can varied to meet customers specific requirement, by changing the percentage ratio of Metal to Filler winding in the Gaskets width. This insures constant Gaskets Compression Stress and provides zero leak joints.


We manufacturer complete rang of Spiral Wound Gaskets as per ANSI, DIN, BS-5500 for Standard Flanges. We also design and manufacturer gaskets for special non-standard flanges. We also Manufacturer Spiral Wound Gasket with Pass Partition Rib's for Heat Exchangers.


HEM's Spiral Seal Gaskets are available in various styles, each designed to suits particular applications.

Basic construction type. Inner and Outer Diameter are reinforced with several piles of Metal winding only to give greater Stability Compression and Sealing Characteristics. Suitable for Tongue and Groove of male and female or groove to flat face flange assemblies.


Spiral Seal Gasket with a solid metal outer ring, which accurately centers gaskets on flange face, provide additional radial strength to prevent gasket blow out and act as compression stop. General Purpose Gasket suitable for use with flat face and raised face flanges.
