The core application areas for water–glycol fire‑resistant hydraulic fluids are industrial sectors where fire hazards—such as high temperatures, open flames, or molten metals—are present and where the safety of hydraulic systems is of paramount importance. In the following industries, these fluids are widely used as critical fire‑safe hydraulic media:
1. Metallurgical Industry
This is one of the primary application areas for water–glycol hydraulic fluids, covering the entire production process from ironmaking and steelmaking to rolling. It effectively prevents fires caused by hydraulic fluid leaks. Specific applications include:
High-temperature furnace area: hydraulic systems of equipment such as converters, electric furnaces, coke ovens, and submerged arc furnaces.
Casting, forging, and hot-rolling equipment: such as continuous casting machines, continuous rolling mills, coilers for hot continuous rolling mills, high-speed wire rod mills, and metal die‑casting machines, among others.
Other high-temperature equipment: such as glass forming machines, cement kilns, and gasifiers, among others.
2. Coal Mining Industry
In underground coal mines, particularly in environments containing flammable and explosive gases such as methane, the use of water–glycol fire‑resistant hydraulic fluid can significantly reduce the risk of fire and explosion. The main equipment includes:
Mining equipment: coal shearers, roadheaders, and continuous miners.
Support equipment: hydraulic supports.
Auxiliary devices: hydraulic tensioning devices, etc.
5. Shipbuilding and Ocean Engineering
The ship’s engine room is a confined space with high personnel density and the presence of high-temperature equipment; using water–glycol hydraulic fluid can reduce the risk of fire. Specific applications include:
Marine equipment: hydraulic systems for steering gear, cargo winches, and other machinery.
Special applications: offshore oil drilling platforms, shipboard hydraulic systems, and more.
6. Chemical Industry
In chemical production, equipment such as high-temperature reaction vessels and high-pressure reactors can prevent accidents caused by leaks by using water–ethylene glycol fire‑retardant hydraulic fluid.
7. Power Industry
It is primarily used in thermal power plants, where it is applied to the hydraulic systems of equipment such as steam turbines and coal mills, helping to prevent fires caused by oil leaks coming into contact with high‑temperature components.
8. Other Important Application Areas
Aerospace: Used in highly safety-critical components such as landing gear and flight control systems.
National Defense and Military Industry: Used in military equipment, sighting devices, and other applications.
Light industry and plastics processing: It is also used in fire‑resistant hydraulic systems for applications such as plastics processing and the light industry.
