Reasons for the ruptured wire layer of the cleaning tube
Reasons for the rupture of the wire layer in a cleaning hose include improper hose assembly, corrosion, and poor lubrication. To resolve the problem, you should reroute the hose or replace the hose clamp. The hose should not be flexed beyond its limits.
The hose was overheated and exposed to high temperatures. This causes the wire layer of the hose to curl, decreasing its compressive strength. Aerated oils can also cause the inner tube to harden and oxidize. This can lead to excessive stretching during the operation.
Improper use is the most common cause. The barb of the fitting can cut into the hose tube if the hose is not used correctly. This can cause the product to escape into the reinforcement, which results in bubbling or blistering. Temperature exposure also affects the hose’s pressure rating. Excessively hot or cold temperatures can cause discoloration, cracking, hardness, and static electricity buildup.
Chemical action, in addition to freezing temperatures, can cause the wire layer to burst. High-velocity fluid streams contain particles that can cause internal tube erosion, which eventually results in a leak. This risk can be minimized by using the right hose size. The right size should match the fluid and its maximum velocities.
Other causes for the rupture of the wire layer of the hose include external abrasion or corrosion. These may be caused by the hose rubbing against nearby hydraulic system parts, brackets, or other hoses. If the hose is damaged, it is essential to replace it with a new one. Protective sleeves can help prevent this problem from recurring.
connection and sealing method of cleaning hose
The connection and sealing method of cleaning hose should meet the applicable standard. Most threaded connections can easily be sealed with thread seal tap. However, some connections may require gaskets or rubber seals. These are not difficult to use, but they must be applied correctly. Leakage can result from incorrect application. It can also be painful to remove.
Precautions when cleaning hoses
Hoses can be cleaned by using warm soapy water. Be sure to thoroughly scrub the inside of the hose. While most hoses can be cleaned in this manner, hoses with electrical components must be cleaned with more care. Heat-treated hoses, for example, should be cleaned according to the manufacturer’s instructions.
To avoid a rupture, it is important to keep water pressure within the rated pressure of a firehose. Never apply too much pressure to a firehose. It is also important to ensure that the hose is dried after use. Avoid using plastic containers to store the hose, as they will trap moisture and can promote mold growth.
Hoses are susceptible to UV rays and abrasion. A weak hose can cause injury to firefighters, and slow down firefighting efforts. Proper storage and cleaning will reduce the chance of a hose breaking. Hoses should be maintained and cleaned regularly.
Before storing hoses, inspect them visually. This inspection can reveal tears, rips, and soft spots. It is also important to check the couplings for debris. It is best to avoid storing the hoses on hot pavements because they can become damaged during storage.
