Low-pressure hoses are pipeline connection components designed for conveying low-pressure fluids. Below is a detailed introduction to low-pressure hoses:

I. Structural Features

Low-pressure hoses are typically composed of an inner tube layer, a reinforcement layer, and an outer cover layer. The inner tube layer is responsible for contacting and sealing the fluid, while the reinforcement layer provides the necessary support and pressure resistance (even though pressure requirements are not high in low-pressure environments, the reinforcement layer still maintains the shape and stability of the hose). The outer cover layer serves as a protective layer, safeguarding the hose from damage caused by external elements.

II. Material Selection

1. ‌Inner tube materialSelect appropriate materials, such as rubber, PVC, and PU, based on the properties of the fluid being conveyed. These materials should possess good sealing properties and resistance to fluid corrosion.

2. ‌Enhanced layer materialIn low-pressure hoses, the reinforcing layer may be made of textile fibers, helical steel wire, or woven mesh, etc. These materials provide sufficient support to maintain the hose's shape stability under low pressure.

3. ‌Coating materialSelect materials with wear and weather resistance to protect the hose from damage by external environments. Common sheathing materials include rubber, PVC, PU, etc.

III. Performance Advantages

1. ‌Low-pressure stabilityLow-pressure hoses maintain stable operation in low-pressure environments, ensuring smooth fluid transmission.

2. ‌Excellent sealing propertiesThe selection of inner tube material and structural design ensures the hose maintains excellent sealing performance under low pressure.

3. ‌Corrosion-resistant to fluidsInner tube material can withstand erosion from various chemical media, extending the service life of the hose.

4. ‌FlexibilityLow-pressure hoses typically offer good flexibility, allowing them to accommodate various complex piping layouts and operating conditions.
