A furnace door coolant is a type water-cooled hose designed for use in steel plants, foundries, and steel mills. It can withstand heat radiation, steel splashes and electrical shocks. It also features a special temperature-resistant two-ply Nomex/Fiberglass cover to provide excellent protection against sparks and molten splatter. It is lightweight, making it easy to handle.
The reason for the ruptured steel wire layer in the special hose for furnace doors cooling is
The rupture of the steel wire layer of the special furnace door cooling hose can occur for a variety of reasons, including the improper application of the hose. When the hose is applied improperly, the barb of the fitting cuts into the tube, allowing product to escape into the reinforcement and cause bubbling or blistering. Another common reason for failure is excessive temperature exposure. Exposure to extreme hot or cold temperatures causes the hose to harden, kink, or crack. It can also cause static electricity to build up.
Excessive twisting of the Hose is the most common cause of hose failure. This reduces its compressive strength, and can lead to hose burst. To prevent excessive torsional movement, hoses should be correctly installed. The hose should be routed straight for at least two times its ID before bending. When pressurized, a bent hose can cause a 4% reduction in the length. If this is the case, a clamping assembly is required to prevent the movement. If the problem persists, the hose should be replaced.
While a steel wire layer in a furnace door cooling special hose is a strong material, it may be weakened over time due to repeated cycling. This happens when the temperature in a pipe is too high to exceed its yield stress. This causes the pipe to deform when it cools, and repeated cycling could cause transverse cracks or even the failure of the panel.
the connection and sealing method of the special hose for furnace door cooling
The furnace door cooling special piping must meet the applicable standard in terms of connection and sealing. The connections to the hose should be made using a plug-and–receptacle combination. The sealing method should include firmly sealing the wire terminals to insulated binding posts.
The air handler cabinet should be sealed to prevent air leakage. Air leakage should not exceed 2% of the design flow rate. To seal seams, you can use putty and mastic. To seal conduit knockouts and junctures, you can also use UL 181A/B tape.
The precautions for the special furnace door cooling hose
Safety is the main focus of the special hose that meets furnace door cooling standards. The hose has an internal design that protects against electrical shock and is durable enough to handle steel splashes, external heat radiation, and sparks. The hose's two-ply Nomex/Fiberglass cover protects against sparks and molten water splatter. It is lightweight for easy handling.
