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 layer, a reinforcing layer, and an outer covering. The inner layer is responsible for contacting and sealing the fluid, the reinforcing layer provides the necessary support and crush resistance (although pressure requirements are not high in low-pressure environments, the reinforcing layer still plays a role in maintaining the hose's shape and stability), and the outer covering serves to protect the hose from damage by external elements.

Section II: Material Selection

1. ‌Inner tube materialSelect appropriate materials such as rubber, PVC, PU, etc., 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-resistant properties 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 choice of inner tube material and structural design ensures the hose maintains excellent sealing performance under low pressure.

3. ‌Chemical fluid resistanceThe inner tube material resists corrosion from various chemicals, extending the hose's lifespan.

4. ‌FlexibilityLow-pressure hoses generally offer good flexibility, enabling them to accommodate a variety of complex piping layouts and operational conditions.
