â… ï¼ŽProduct Introduction
The Oxygen Pipeline Flame Arrestor (Model: ZHQ-FQ/FM) is a specialized safety protection device designed for oxygen transmission pipelines. It is mainly divided into two types according to the installation position: FQ type (installed in front of the valve) and FM type (installed behind the valve), which can meet the safety protection needs of different positions in the oxygen pipeline system. The product adopts a scientific structural design, with the main structure consisting of a middle flame-retardant section and pipe sections at both ends. In terms of connection methods, it provides two options: flange connection and welding connection, which can be flexibly selected according to the actual installation environment and pipeline specifications of users.
Widely used in metallurgical, chemical and other industries that involve oxygen transmission, this flame arrestor plays a crucial role in ensuring the safe operation of oxygen pipelines. In the process of high-speed oxygen transmission, debris in the pipeline may cause sharp friction with the pipe wall, which is likely to generate fire sources and trigger serious accidents such as pipeline explosions. The ZHQ-FQ/FM oxygen pipeline flame arrestor can effectively cut off such fire sources, fundamentally preventing the occurrence of explosion accidents. The product has the characteristics of simple installation and easy operation; users can directly connect it to the appropriate position of the oxygen pipeline to realize immediate safety protection without complex supporting equipment or cumbersome debugging procedures.
Ⅱ．Product Features
-
Clear Classification and Wide Adaptability: It is clearly divided into FQ type (front of the valve) and FM type (rear of the valve) according to the installation position, which can accurately match the safety protection requirements of different sections of the oxygen pipeline. At the same time, it provides flange and welding connection methods, adapting to various pipeline connection standards and installation scenarios in metallurgical, chemical and other industries.
-
Efficient Flame Retardancy and Explosion Prevention: The middle flame-retardant section adopts high-performance flame-retardant materials and advanced structural design, which can quickly and effectively cut off the fire source generated by the sharp friction between debris and the pipe wall in the high-speed oxygen flow. It has excellent flame-retardant efficiency and can prevent the spread of fire and the occurrence of pipeline explosions to the greatest extent.
-
Stable Structure and Reliable Performance: The overall structure is designed reasonably, with high structural strength and good pressure resistance. It can operate stably for a long time under the working conditions of oxygen pipeline (such as high pressure, high flow rate), and is not easy to be deformed or damaged. It has strong resistance to corrosion and wear, and can adapt to the harsh working environment in metallurgical and chemical industries.
-
Simple Installation and Convenient Use: The product structure is compact, and the installation process is simple and fast. Users can complete the connection with the oxygen pipeline through flange or welding according to the actual situation. After installation, it can work stably without frequent maintenance, which effectively reduces the user’s operation and maintenance costs.
-
Strong Compatibility: It is compatible with most oxygen pipeline specifications in the market, and can be customized according to the special needs of users (such as special pipeline diameter, pressure level, etc.), ensuring a perfect match with the user’s existing pipeline system.
