High Temperature Seal Gaskets

High Temperature Seal Gaskets

Static Flange Gaskets High-Temperature-Resistant, Static Metal Gaskets for Demanding Exhaust Applications Gaskets for Demanding Exhaust Applications High temperature seal gaskets from Metal Textiles create a secure seal under extremely low and high temperatures and in demanding corrosive environments. Metal Textiles static flange gaskets can provide:   Zero leakage at pressures of up to 2 Bar Recovery after compression of 90% Minimum sealing stress of 10N/mm2 Temperature resistance from -50° C to 800° C Cross section from 4 mm to 8 mm Inside diameters from 38 mm to 127 mm Custom cross-sections and ID also available Exhaust System Sealing Technology that Keeps Pace with Emission Regulations   As the automotive industry continues to keep pace with new emissions regulations, the requirements of exhaust system joints become increasingly demanding. These joints must not only prevent the release of untreated exhaust gas, they must also combat ingestion of oxygen into the exhaust system-which can have adverse effects on the closed-loop emission control system. To meet these stringent demands, Metal Textiles engineers have developed a system approach to joint design, and coupled that with advances in seal and gasket materials, geometry, and construction. An all-metal ring gasket that improves performance A thin metal jacket fully encapsulates a knitted wire mesh core. This all-metal construction eliminates filler material burn-out and provides far greater resiliency over traditional automotive flange gaskets-even at elevated temperatures. In addition, all component materials can be custom-tailored to achieve further gains in resiliency. The gasket is designed to fit into a groove in the flange, with the groove depth sized to limit ring compression, allowing the gasket to operate in a set portion of the compression/recovery curve. Designed for installation between two geometrically identical flanges welded to adjacent system components. The slight oval shape of the gasket locks firmly into the flange groove or around the pipe’s OD during assembly. The seal is constructed of a stainless steel foil ring with a round, rectangular, or oval cross-section formed around a resilient knitted wire mesh core. This durable seal has unique spring-back properties and, due to its all-metal design, is ideal for high-temperature and high-corrosion environments. Available with a sheet-metal carrier which fits over the studs that hold the gasket in place...

Spherical Joint System

Spherical Joint System

A New, Low-cost, Spherical Joint System Design for Automotive Applications   The Metal Textiles Spherical Joint System combines breakthrough innovation and global best-practices of the classic spring-loaded exhaust decoupler ball joint in a turnkey system to assure consistent superior performance for the life of the vehicle. Using a system approach, the proven durable exhaust ball joint technology has been optimized to provide near zero-leak performance at a fraction of the cost of bellows-based systems, while meeting the stringent durability and customer satisfaction needs of major automotive manufacturers worldwide. The self-supporting exhaust decoupler design can support the weight of the exhaust system in either the vertical or horizontal direction, eliminating the need for additional hangers. In addition, the system displays stable, consistent, dynamic behavior throughout the life of the vehicle. The Metal Textiles spherical-loaded joint system offers the following performance characteristics: Operating temperatures up to 700°C (flange surface) Less than 1.0 standard liters per minute leakage at pressures up to 34kPa when new Less than 2.0 standard liters per minute leakage at pressures up to 34kPa after vehicle durability tests Pipe outside diameters from 38 mm to 76 mm The Metal Textiles spherical joint system is a complete “turnkey” spring-loaded ball joint for use in the exhaust systems of internal combustion engines. The system was developed to provide a joint with “near-zero” leakage performance in automotive exhaust systems, while acting as a: Exhaust decoupler to isolate the vibrations of the engine from the remainder of the exhaust system and the passenger compartment. This is extremely important in automobiles where any reduction in noise, vibration, and harshness (NVH) will improve ride quality. Pivot point to stop the exhaust system from moving when the engine exhibits large amplitude rolling motion. This is most important in front wheel drive (FWD) vehicles with transverse mounted engines. In these cases, the roll axis of the engine is perpendicular to the axis of the exhaust system. With no pivot point, the exhaust will slam into the vehicle underbody, or the ground, when the engine rolls upon gear changes and acceleration/deceleration. Evolutionary Design for Spherical Joint System to Reduce Vibration and Enhance Product Quality   The Metal Textiles Spherical Joint System represents evolutionary refinements to the classic automotive...

Intro to Knitted Wire Mesh

Intro to Knitted Wire Mesh

Knitted wire mesh consists of a metal wire strand knitted into a mesh structure in very much the same way as stockings or sweaters. Knitting produces mesh of interlocking loops and these loops move relative to each other in the same plane without distorting the mesh, giving knitted mesh a two-way stretch not found in woven wire products.   Forms of Knitted Mesh Knitted mesh is produced on a cylindrical machine and produced as a continuous tube of mesh which is pulled through the knitter by take-up rollers which also flatten the tube into a two-ply mesh in widths between approximately1” and 42” wide. It can be used directly in this flattened form for many applications or it can be further processed into several other basic forms. Flattened mesh is oftentimes run through corrugating rollers to create crimped mesh. In this form, the corrugations act like springs for resiliency and give the mesh added thickness and increased height. Crimped mesh is also used to create compressed, die-formed units for use as filters, shock isolators, flame arrestors and other durable items. In this case, the mesh is formed in a custom made die-set. These parts are available in densities (% metal by volume) ranging from 10% to 60%. Compressed mesh can also be made in a continuous strip form by running the mesh through calendaring rollers. Mesh can also be knitted into a hollow tube which is then pulled through dies and over forming balls to make rope-seals, spring-tubes and core material for tadpole and other high-temperature gaskets.   Properties of Knitted Mesh Knitted mesh has distinct advantages over most competitive materials. Because each loop acts as a small spring when subjected to tensile or compressive stress, knitted metal has an inherent resiliency. If it’s not distorted beyond its yield point, the material will resume its original shape when the stress is removed. Even when it’s compressed into a special shape, a high degree of resiliency is retained. Varying the knitted structure, wire diameter, strand count, wire material and forming pressure used to create the part can help control this characteristic. Among the most important property of knitted mesh units is the material itself. By careful selection of the material...
