Double Jacket Gasket with Graphite Filler for Maximum Reliability

DOUBLE JACKETED GASKET

Our exquisitely crafted metal jacketed gaskets are engineered with a robust thin metallic outer shell that encases a resilient filler material. This innovative design ensures the utmost protection for the filler, offering exceptional resistance to pressure, temperature, and corrosion. Each gasket is meticulously handmade, available in a diverse array of shapes and sizes, with a premium selection of metals and fillers. Configurable internal ribs provide additional versatility. These gaskets are indispensable for heat exchanger applications, though they do require precision flange surfaces and high bolt loads to achieve an optimal seal.

Single jacketed gaskets feature one surface and are completely enveloped by a metal jacket covering both the OD and ID. They are ideal for narrow flange widths in low pressure valve and pump applications.

Double jacketed gaskets are ingeniously designed with a two-piece metal jacket that fully encapsulates the OD, ID, and both sealing surfaces. They are predominantly utilized in heat exchanger applications and are adept at handling corrosive and high temperature environments.

Internal ribs, or pass partition bars, can be seamlessly integrated or expertly welded, ensuring the primary seal remains uncompromised in both configurations.

APPLICATION

> Heat exchangers

> Gas mains

> Boiler and fues

> Pumps.

> Valve bonnets

Gaskets with straightforward designs are perfect for pipeline flanges and sealing surfaces of internal-combustion machines. Those with intricate shapes excel in the flange covers of heat exchangers and similar applications. Typically, general gaskets span 10-25 MM in width and 2MM-8MM in thickness, and can withstand maximum working pressures of 6-10Mpa, making them versatile and reliable.

Jackets are crafted from a selection of high-quality materials including soft iron, low carbon steel, stainless steel, nickel, copper, aluminium, brass, titanium, monel, and more.

The filler options include expanded graphite, ceramic, PTFE, and other resilient materials.

The gasket thickness tolerance is precisely set at (+0.03 inch., -0.000 inch) (+0.8mm, -0.0mm), ensuring exacting standards.

(1). For gaskets ranging from NPS 1/2 to NPS 24, the outside and inside diameter tolerances are meticulously controlled at +0.06 inch, -0.0 inch (+1.5mm, -0.0mm);

(2). For NPS sizes 1/2 through 3, Class 400 flanges are unavailable, requiring the use of Class 600 instead;

(3). For NPS sizes 1/2 through 2-1/2, Class 600 flanges do not exist, necessitating the use of Class 1500;

(4). Class 2500 is unavailable for NPS sizes 14 and larger.
