DOUBLE JACKETED GASKET
Ningbo Dongheng Sealing Co., Ltd. proudly presents our exquisite Premium Double Jacket Gasket with Non-Asbestos Filler for Industrial Use. Masterfully engineered, these gaskets feature a robust metallic shell that elegantly encases a durable filler material, ensuring unparalleled protection and endurance. This sophisticated design delivers superior resistance against pressure, temperature, and corrosion challenges, catering perfectly to stringent industrial demands. Every gasket is meticulously handcrafted and available in an extensive array of shapes and sizes, with a premium selection of metals and fillers to suit diverse needs. Customizable internal ribs add an extra layer of versatility, making these gaskets indispensable in heat exchanger applications. While they demand precision flange surfaces and high bolt loads to achieve an optimal seal, the payoff is unmatched reliability and performance.
Single jacketed gaskets are designed with precision to feature one sealing surface, entirely enveloped by a protective metal jacket covering both the OD and ID. These gaskets excel in applications with narrow flange widths, perfectly suited for low-pressure valve and pump systems.
Ingeniously crafted, double jacketed gaskets are designed with a two-piece metal jacket that fully encapsulates the OD, ID, and both sealing surfaces. These gaskets are predominantly utilized in heat exchanger applications, showcasing exceptional adeptness in managing corrosive and high-temperature environments, thereby extending their utility and durability.
Internal ribs, or pass partition bars, can be seamlessly integrated or expertly welded into the gasket's design. This ensures that the primary seal remains uncompromised, providing extraordinary reliability and efficiency in both configurations.
APPLICATION
> Heat exchangers
> Gas mains
> Boiler and fues
> Pumps.
> Valve bonnets
Gaskets with straightforward designs are ideally suited for pipeline flanges and sealing surfaces of internal-combustion machines. Those with intricate shapes are perfect for flange covers of heat exchangers and similar sophisticated applications. Typically, these versatile gaskets span 10-25 MM in width and 2MM-8MM in thickness, standing resilient against maximum working pressures of 6-10Mpa. This makes them a reliable choice for various industrial uses.
Jackets are meticulously crafted from an exquisite selection of high-quality materials, including soft iron, low carbon steel, stainless steel, nickel, copper, aluminium, brass, titanium, monel, and many more.
The filler materials include top-tier options such as expanded graphite, ceramic, PTFE, and other resilient compounds, ensuring enhanced durability and performance.
The gasket thickness tolerance is precisely calibrated to meet exacting standards, set at (+0.03 inch., -0.000 inch) (+0.8mm, -0.0mm), guaranteeing superior precision.
(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), adhering to strict quality standards;
(2). For NPS sizes 1/2 through 3, Class 400 flanges are not available, requiring the use of Class 600 as a competent alternative;
(3). For NPS sizes 1/2 through 2-1/2, Class 600 flanges are unavailable, necessitating the use of Class 1500 for optimal performance;
(4). Class 2500 is unavailable for NPS sizes 14 and larger, thereby requiring suitable alternatives.
