Rubber tubing is a versatile tubular product predominantly crafted from rubber, usually featuring an inner and outer rubber layer along with a skeletal reinforcement layer. This innovative product is designed to transport gases, liquids, slurries, or granular materials efficiently. The primary role of rubber tubing is to enable the seamless transmission of media, leveraging its superb elastic sealing and pressure-bearing capabilities. Its profound utility spans across diverse sectors including industrial, automotive, and medical fields, making it an integral component of modern engineering.
1. Introduction to Rubber Pipe Materials
Crude Rubber: Known for its remarkable high elasticity, this material exhibits wear resistance, bending, and scratching properties, making it ideal for low-pressure environments.
Protobutadiene Rubber (SBR): Offers outstanding wear resistance and is cost-effective, although it has limited oil resistance.
Cis-Polybutadiene (BR): Features excellent moisture and low-temperature resistance, retaining elasticity even at a frigid -50ºC.
Nitrile Rubber (NBR): Provides superior oil resistance, particularly against mineral and lubricating oils, but is less effective against ozone and high temperatures.
Chloroprene Rubber (CR): Balanced in performance, it is resistant to oil, ozone, and aging, making it a well-rounded choice for various applications.
EPDM Rubber (EPDM): Excels in high-temperature environments (-50~150ºC) and offers robust weather resistance, perfect for long-term outdoor exposure.
Fluorine Rubber (FKM): Withstands high temperatures (-20~250ºC) and resists chemical corrosion, ideal for extreme conditions.
Silastic (VMQ): Exceptional high-temperature resistance (-70~300ºC) coupled with high transparency and excellent electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Resilient to strong acids and alkalis like concentrated sulfuric and nitric acid, and boasts excellent permeability resistance.
Conductive Rubber: Incorporates conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, this material has passed UL 94 flame retardant certification, ensuring greater safety.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly interfaces with the transport medium, offering wear and corrosion resistance, including resistance to oil, acid, and alkali.

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 classified into various types such as sandwich hoses, braided hoses, winding hoses, and full hoses, each designed for specific applications.
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 Assurance:
| 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. |
