How fire hose is manufactured?
In the manufacturing process, a NBR/PVC rubber compound is extruded through a textile jacket, and the covered (in and out) hose is vulcanized in a discontinuous process with water steam injected into the rubber hose.
The manufacturing process of fire hoses involves several steps to ensure the production of high-quality, reliable firefighting equipment. While variations exist between manufacturers, the general process remains similar.
First, the materials for the inner lining, reinforcement layer, and outer cover are selected based on their desired properties, such as strength, flexibility, and resistance to heat and chemicals.
The manufacturing process typically begins with the preparation of the inner lining material, which is extruded or formed into a tube shape. This tube is then subjected to vulcanization, a process that involves heat and pressure to enhance the material’s durability and resistance.
Next, the reinforcement layer is added. High-strength synthetic fibers, such as polyester or nylon, are woven or braided onto the inner lining, providing structural strength and preventing the hose from bursting under high pressure.
Once the reinforcement layer is in place, the outer cover material is applied. It is wrapped or extruded over the reinforcement layer, providing protection against abrasion, chemicals, and other external factors.
After the hose construction is complete, it undergoes rigorous quality control inspections to ensure that it meets industry standards and regulations. These inspections may involve testing for pressure resistance, flexibility, and other performance characteristics.
