Boiler specific high-temperature steam hose
The core structure of flame-retardant and anti-static steel wire wrapped steam pipe lies in its multi-layer composite design. This pipe is based on high-density EPDM and other polymer materials, and is embedded with two or more layers of steel wire mesh reinforcement layers wound between the inner and outer layers through a special process. These steel wires not only have high strength characteristics, but their outer layer is also covered with a coating layer that has hot melt adhesive properties and water resistance. During the manufacturing process, the steel wire is tightly wrapped around the core tube, and then subjected to heating treatment to synchronize the extrusion coating of the intermediate bonding layer and the outer polymer material, ultimately forming an integrated composite structure.
To enhance the flame retardant and anti-static properties of pipes, specific flame retardants and anti-static agents are added during the manufacturing process. For example, by using inorganic conductive powders mainly composed of conductive carbon black and organic antistatic agents, the surface resistivity of EPDM materials is significantly reduced through multiple composite, heating, and vacuum processes, thereby achieving rapid conduction and dissipation of electrostatic charges. This design not only enhances the mechanical strength of the pipe, but also greatly improves its safety and durability.
Performance advantages and application scenarios
Flame retardant and anti-static steel wire wrapped steam pipes have multiple performance advantages. Its flame retardant properties can effectively delay the spread of fire and reduce the risk of fire; Anti static design can avoid safety hazards caused by static electricity accumulation, especially suitable for flammable and explosive environments. The lightweight and high flexibility of pipes make them easy to install and adjust in complex layouts, while their drug resistance ensures stable performance when transporting corrosive media. In addition, the smooth inner wall of the pipe can reduce fluid resistance and improve transportation efficiency.
In industrial applications, this pipe is widely used in high-temperature steam transportation systems, such as thermal power plants, chemical production equipment, and textile machinery. Its high temperature resistance (able to withstand high temperatures of 140 ℃ -180 ℃) and high pressure bearing capacity make it an alternative to traditional metal pipes. Meanwhile, the anti-static properties of the pipes also make them suitable for precision manufacturing environments that require anti-static treatment, such as electronic component production workshops.
Key points for installation and maintenance
When installing flame-retardant and anti-static steel wire wrapped around steam pipes, it is necessary to strictly follow the standard procedures. Firstly, it is necessary to ensure the stability of the pipeline supports, and the spacing between supports should be designed reasonably based on parameters such as pipe diameter, wall thickness, and temperature. During the connection process, reliable methods such as welding or threaded connections should be used to ensure sealing. For key parts such as elbows and valves, specialized molded products or precise processing are required to avoid stress concentration.
In daily maintenance, it is necessary to regularly check the surface of the pipe for damage, aging, or corrosion, especially paying attention to the bonding state between the steel wire reinforcement layer and the inner and outer layer materials. For discovered problems, damaged pipe sections should be repaired or replaced in a timely manner to prevent the accident from escalating. In addition, it is necessary to keep the surrounding environment of the pipe clean, avoid scratching the pipe wall with sharp objects, and regularly clean the internal dirt to ensure transportation efficiency.
