Rubber tubing, a marvel of engineering, is an essential tubular product crafted primarily from high-quality rubber. It typically comprises an inner and outer rubber layer fortified with a robust skeleton layer. This dynamic structure enables the transportation of gases, liquids, slurries, or granular materials with unparalleled efficiency. The core function of rubber tubing lies in its exceptional ability to facilitate media transmission through its remarkable elastic sealing and pressure-bearing capabilities. It finds widespread application across numerous fields, including the industrial, automotive, and medical sectors, ensuring seamless and reliable performance.
1. Introduction of Rubber Pipe Material
Crude Rubber: Renowned for its high elasticity, wear resistance, and excellent bending and scratching characteristics. It is ideally suited for low-pressure environments, ensuring optimal performance and longevity.
Protobutadiene Rubber (SBR): Celebrated for its excellent wear resistance and cost-effectiveness. However, it possesses limited oil resistance, making it ideal for specific applications where oil exposure is minimal.
Cis-Polybutadiene (BR): Offers exceptional moisture resistance and outstanding low-temperature resilience, maintaining elasticity even at a chilling -50ºC.
Nitrile Rubber (NBR): Known for its excellent oil resistance, particularly against mineral oils and lubricating oils. However, it exhibits limited ozone and high-temperature resistance.
Chloroprene Rubber (CR): Provides a harmonious balance of oil resistance, ozone resistance, and aging resistance, resulting in a well-rounded performance profile.
EPDM Rubber (EPDM): Excels in high-temperature conditions ranging from -50 to 150ºC, coupled with strong weather resistance, making it perfect for outdoor and prolonged exposure.
Fluorine Rubber (FKM): Distinguished by its superior high-temperature tolerance (-20 to 250ºC) and chemical corrosion resistance, ideal for extreme environmental conditions.
Silastic (VMQ): Boasts unmatched high-temperature tolerance (-70 to 300ºC), high transparency, and exceptional electrical performance, making it a versatile choice for numerous applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers stellar resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, with formidable permeability resistance.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh, it effectively prevents static accumulation, ensuring safety and reliability.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, and successfully passed the UL 94 flame retardant certification, ensuring superior fire safety.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Designed for direct contact with the conveying medium, it offers remarkable wear resistance and corrosion resistance, including oil, acid, and alkali resistance.

Enhance the strength of the tube body, including cotton thread, steel wire, synthetic fiber, etc., to determine the pressure bearing capacity (e. g., the steel wire woven layer can withstand 80~600MPa pressure). |
| External glue layer |
Protect the internal structure from the external environment (such as ultraviolet light, mechanical friction). |
3. Structurally, rubber pipes are categorized into various innovative types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each serving specific applications with outstanding efficiency.
4. Working Principle of Rubber Pipe
| Pressure transmission and energy buffer |
The hydraulic hose transfers the force through the fluid pressure, and uses the elastic shape of the rubber to absorb the pressure pulsation, and reduce the vibration of the system. For example, the hydraulic pipe of construction machinery bears high pressure (up to 60MPa or above) through a multi-layer steel wire reinforced layer. |
| Shock absorption and displacement compensation |
Rubber soft connection (e. g., flexible rubber joint) absorbs pipe displacement through the elastic deformation of the curtain layer and wire ring to reduce operating noise, which is suitable for pump valve connection and frequent vibration line. |
| Media isolation and leakage prevention |
The compactness of the inner adhesive layer combines with the protection of the outer adhesive layer to prevent the leakage of water, gas or chemicals. For example, the mobility of the coolant between the car radiator and the engine. |
5. Application Areas:
| industrial circle |
Welding gas delivery, hydraulic system, mine ventilation. |
| automotive filed |
Coolant circulation, fuel transmission, air-conditioning system. |
| Medical field |
Infusion tube, surgical instrument catheter. |
| The field of agriculture |
Irrigation system, aquaculture equipment. |
| New energy field |
Automobile battery and wind turbine cooling system, etc. |
6. Standardization and Security Guarantee:
| high-voltage insulation test |
Burst pressure is 3 times the working pressure (such as hydraulic hose). |
| degradation testing |
Simulated high temperature / UV environment assessment life (theoretical value of more than 15 years). |
| Environmental requirements |
Biological based rubber and low VOC (volatile organic compounds) formula meet the sustainable development needs. |
