The flanged coupling is a firefighting-specific device that uses flange plates (metal rings with bolt holes) to achieve a rigid pipe connection. The connection is secured through bolt fastening, ensuring high-pressure sealing.
Flanged couplings are typically found in various high-pressure, high-flow firefighting systems and are suitable for:
● Fixed fire piping networks (permanent connections in systems like sprinkler systems or fire hydrant pipelines within buildings).
● Fire pump connectors (allowing fire trucks to inject water into a building's pipeline network through the flanged coupling, supplementing the water supply for firefighting).
● Industrial firefighting systems (such as in oil, chemical, and other high-pressure environments, where corrosion-resistant connections are required).
27 Years Of Industry Manufacturing Experience
The Flanged Couplings is a pipe connection device with a stable structure and reliable sealing. It is widely used in various high-pressure and high-flow fire protection systems. The Flanged Couplings consists of two metal flanges with bolt holes. The flanges are compressed by multiple bolts to achieve a firm rigid connection. This connection method can effectively resist the impact and vibration of high-pressure water flow and ensure the reliable operation of the system in emergency water supply. Our company has strong independent research and development capabilities in mold manufacturing and processing accuracy, ensuring that each flange joint has excellent structural stability and tightness, suitable for various extreme working conditions.
The flanges are equipped with high-quality sealing gaskets, and the contact surfaces are tightly fitted through the extrusion force of the bolts, thereby achieving stable sealing under high pressure. Especially in complex environments such as high-rise buildings and underground pipe networks, flange joints can effectively prevent water leakage and ensure that the fire water supply system always maintains normal operation. The company is equipped with advanced product testing equipment to test the sealing performance piece by piece, control the quality from the source, and win the long-term trust of many customers.
The Flanged Couplings can be flexibly customized according to the system design requirements, covering a wide range of specifications from DN50 to DN600 and above, and is particularly suitable for the main water supply pipes or high-flow pump station networks of fire protection systems. We pay close attention to customer needs and industry development trends, continuously develop new products, and provide customers with personalized solutions to meet the growing demand for efficient water delivery.
In special application scenarios such as industrial fire protection, our company uses high-strength materials such as stainless steel, carbon steel galvanized, and ductile iron, combined with anti-corrosion coating technology to ensure that the product can work stably and long-term in high temperature, high humidity, and corrosive media environments. Our manufacturing process strictly controls the selection of raw materials, and through a complete set of production, processing and testing systems, we ensure that each product has excellent pressure resistance and corrosion resistance.
The Flanged Couplings has a standard structure, which is easy to install and disassemble quickly, greatly improving the maintenance efficiency and emergency response capabilities of the fire protection system. It is especially suitable for buildings or industrial systems with extremely high requirements for water supply reliability. At the service level, we always adhere to the core concepts of "quality commitment" and "partnership", provide customers with professional support and rapid response, and help achieve long-term sustainable partnerships.
Flanged Couplingss play an important role in many scenarios such as building automatic sprinkler systems, fire hydrant pipes, fire pump connections, industrial plants and temporary fire water supply interfaces. They are an important component of efficient and safe water supply systems.
