Sintered Metal Flame Arresters

Sintered metal flame arresters are designed to prevent the propagation of flames in gas or vapor handling systems. They are typically composed of a cylindrical housing with a sintered metal element inside. The element is made up of multiple layers of metal powder that are compressed and sintered (heated without melting) to form a porous material with precise pore sizes and distribution. Product parameters Material: stainless steel 304/316L Pore size: 0.2um, 0.5um, 2um, 5um, 10um, 15um, 20um, 40um, 60um, 90um, 100um Technology: Powder Sintering Temperature range: below 600 C Style: customized according to customer needs Features Effective flame arrestation: The porous material of the sintered metal element acts as a filter, allowing gas or vapor to pass through while trapping any flames or sparks. This helps to prevent the risk of fire or explosion in industrial settings where flammable gases or vapors are present. Precise flow control: The pore size and distribution of the sintered metal element can be tailored to control the velocity and direction of gas or vapor flow. This allows for precise flow control, which is important in many industrial applications. Durable and long-lasting: Sintered metal flame arresters are made from high-quality materials that are designed to withstand harsh industrial environments. They are typically very durable and long-lasting, providing reliable flame arrestation for many years. Low maintenance: Sintered metal flame arresters require minimal maintenance, making them a cost-effective solution for many industrial applications. Regular inspections and cleaning can help ensure that the porous element remains free of debris and in good working condition. Application Oil storage tanks are commonly used to store crude oil, refined petroleum products, and other flammable liquids. In order to prevent the risk of fire or explosion, flame arresters are often installed on the vents of these tanks. When the tank is filled or emptied, a mixture of air and flammable vapors is released through the vent. If a flame were to ignite this mixture, it could cause a catastrophic explosion. However, by installing a flame arrester on the vent, the flammable vapors are filtered through the sintered metal element, preventing any flames or sparks from passing through. In addition to storage tanks, sintered metal flame arresters are also commonly used in pipelines that transport crude oil, refined petroleum products, and other flammable gases or vapors. They can be installed at various points along the pipeline to prevent the propagation of flames in the event of a fire or explosion.

A flame arrester (also spelled arrestor), deflagration arrester, or flame trap is a device that stops fuel combustion by extinguishing the flame. A flame arrester (also called a deflagration arrester) functions by absorbing the heat from a flame front traveling at sub-sonic velocities, thus dropping the burning gas/air mixture below its auto-ignition temperature: consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element. These channels are chosen and measured as the MESG (Maximum Experimental Safe Gap) of the gas for a particular installation. These passages can be regular, like crimped metal ribbon or wire mesh or a sheet metal plate with punched holes, or irregular, such as those in random packing. Principle Flame arresters are passive devices with no moving parts. They prevent the propagation of flame from the exposed side of the unit to the protected side by the use of metal matrix creating a torturous path called a flame cell or element. All detonation flame arresters operate on the same principle: removing heat from the flame as it attempts to travel through narrow passages with walls of metal or other heat-conductive material, but unlike flame arresters, detonation flame arresters must be built to withstand extreme pressures that travel at supersonic velocities, 1,500 psi (10 MPa) at 2500 m/s is not uncommon with a group D Gas.

Product Introduction Stainless steel porous flame arrestors are commonly used in a wide range of industries to prevent the propagation of flames and explosions in systems that handle flammable gases or fluids. They are highly effective at trapping or extinguishing flames while allowing for the efficient flow of gases or fluids. Stainless steel is a popular material due to its high strength, corrosion resistance, and ability to withstand high temperatures. The stainless steel porous filter element is the key component of the flame arrestor and is designed to trap or extinguish any flames that may be present in a gas or vapor stream while allowing gases or fluids to flow through. When a gas or vapor mixture passes through the porous filter, any flames present will be cooled and extinguished due to the heat dissipation and surface area of the filter. This prevents the flame from propagating further down the pipeline or vessel and causing a fire or explosion. The porous filter also provides a large surface area for vapor or gas to pass through, allowing for efficient flow and minimal pressure drop. Stainless steel is a popular material for flame arrestor filters due to its high strength, corrosion resistance, and ability to withstand high temperatures. Parameters Place of originï¼?
