How to correctly use fire fighting hoses
Industrial rubber hoses are essential materials in various industries. In food processing, you need special food-grade hoses to transport food or beverages. In the chemical industry, chemical hoses are required to convey acids, alkalis, and solvents. Generally, rubber hoses have a long service life, but proper use and installation are crucial. There are many factors to consider when installing rubber hoses, with the following six points being the most critical:
Prevent Deformation During Installation
To ensure the rubber hose operates properly, avoid deforming it during installation, including axial, transverse, or torsional strain. This helps correct installation errors in the pipeline system’s positioning.
Ensure Unobstructed Movement
All movable components of the rubber hose must not be blocked by external parts, as this could restrict their normal movement. Regularly check for obstructions to maintain flexibility.
Gradual Valve Operation
When operating pipelines with rubber hoses, open and close valves gradually. Sudden pressure changes in the pipeline can damage brackets or the hose itself, so steady adjustments are key.
Meet Bracket Design Requirements
Brackets must adhere to design specifications. Never test pipeline pressure before installing brackets, as this can severely damage the rubber hose.
Proper Insulation Practices
If pipes require insulation, apply it to the rubber hose’s outer protective sheath. Avoid using chlorine-containing insulation materials, as they may degrade the hose over time.
Protect During Handling
Rubber hoses are made from thin-walled materials, making them vulnerable to damage. During transportation and storage, safeguard them from impacts, scratches, arc ignition, welding spatter, and other hazards.
