Rubber tubing is an essential and versatile tubular product primarily crafted from durable rubber. It typically features a robust inner and outer rubber layer, along with a resilient skeleton layer. This sophisticated construction is designed for the efficient transport of gases, liquids, slurries, or granular materials. The fundamental purpose of rubber tubing lies in its ability to facilitate the seamless transmission of media through its impressive elastic sealing and pressure-bearing capabilities. It finds extensive applications across diverse fields such as industry, automotive sectors, and medical treatment facilities.
1. Introduction of Rubber Pipe Material
Crude Rubber: Renowned for its high elasticity, this material offers superior wear resistance, excellent bending and scratching characteristics, making it ideal for low-pressure environments.
Protobutadiene Rubber (SBR): Known for its exceptional wear resistance and cost-effectiveness, though it exhibits poor oil resistance.
Cis-Polybutadiene (BR): Offers remarkable moisture resistance along with outstanding low temperature performance, remaining elastic even at -50ºC.
Nitrile Rubber (NBR): Excels in oil resistance, particularly against mineral oils and lubricating oils, but has weaker ozone and high temperature resistance.
Chloroprene Rubber (CR): Provides a balanced performance with oil resistance, ozone resistance, and aging resistance.
EPDM Rubber (EPDM): Demonstrates remarkable high temperature resistance (-50~150ºC) and strong weather resistance, making it suitable for prolonged outdoor exposure.
Fluorine Rubber (FKM): Offers outstanding high temperature resistance (-20~250ºC) and chemical corrosion resistance, ideal for extreme environments.
Silastic (VMQ): Known for its exceptional high temperature resistance (-70~300ºC), high transparency, and superior electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Resistant to strong acids and alkalis, such as concentrated sulfuric and nitric acids, and provides excellent permeability resistance.
Conductive Rubber: Features built-in conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Contains flame retardants like aluminum hydroxide and has achieved UL 94 flame retardant certification.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly contacts the conveying medium and boasts wear resistance, along with corrosion resistance against 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 categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses.
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. |
