Metal Jacketed Gaskets

Style : 510

 

 

metag1

Flexiteck metal jacketed gaskets are specially designed and widely used on smooth flange applications and are ideal for Heat Exchangers, Auto Claves, Columns, Engines, Boilers, Gas Mains, Valve Bonnets and similar services. Jacketed gaskets consist of a sheet metal jacket, and a filler of asbestos, CAF, Graphite, Mica, Ceramic or some layers of sheet metal. The jacket metal should be as soft as plastic as possible taking into account the corrosiveness of the fluid to be sealed.

 


 

 

The filler material is chosen according to the imperfection of the flange.
The better the surface finish and the flatness of the flange face, harder the filler can be.

 

Jacket material : Soft iron, Copper, Brass, Aluminium, SS304, 316, 316L, 321, 410, Monel, F5, Incoloy, Titanium, and etc.

 

Filler : CAF, Non-Asbestos, Teflon, Graphite, Ceramic and etc.

 

WELDED CONSTRUCTION
The bars are securely spot welded by sophisticated welding techniques (mig, tig, and plasma arc) to the all important outer ring.
Welded-In-Bar Exchanger Gaskets offer the following benefits over One-Piece Gaskets with integral bars :

 

Lower Price - Typical cost savings 10% to 40% (dependent on material).
Quicker Delivery - Less time to manufacture.
Technically Superior and Safer - Extra sealing safeguards - A better gasket.
Longer Sealing Life - Bars seal independently of the outer ring.
New and higher Standards of Technical Quality.

 

The overlapped seams produce a locally high seating stress which contributes to the effectiveness of the seal in critical areas. The crucial sealing area is the peripheral ring which prevents media leakage to atmosphere. Slight leakage across the pass-bars is tolerable since the exhanger manufacturer builds-in a designed efficiency-loss catering for leakage at this point.
