Metal Jacketed Gaskets

Style : 510

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

Jacket material : Soft iron, Copper, Brass, Aluminium, SS304, 316, 316L, 321, 410, Monel, F5, Incoloy, Titanium, 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 into the atmosphere. Slight leakage across the pass-bars is tolerable since the exchanger manufacturer builds in a designed efficiency-loss catering for leakage at this point.
