Rubber tubing is a tubular marvel specifically engineered from rubber, typically showcasing an intricate construction of both an inner and outer rubber layer, complemented by a robust skeleton layer. Its primary purpose is the seamless transportation of gases, liquids, slurries, or granular materials. With unparalleled elastic sealing and pressure-bearing capabilities, rubber tubing stands as a pillar in facilitating media transmission across diverse arenas, including industry, automotive innovation, and the realm of medical treatment.
1. Introduction to the Material Composition of Rubber Pipes
Crude Rubber: Celebrated for its remarkable high elasticity, exceptional wear resistance, and notable resistance to bending and scratching, this material thrives in low-pressure environments.
Protobutadiene Rubber (SBR): Renowned for its extraordinary wear resistance and cost-effectiveness, although it exhibits limited oil resistance.
Cis-Polybutadiene (BR): Offers excellent moisture resistance and exceptional low-temperature resilience, maintaining elasticity even at a chilling -50ºC.
Nitrile Rubber (NBR): Prized for its outstanding oil resistance, particularly against mineral and lubricating oils, yet shows some vulnerabilities in ozone and high-temperature conditions.
Chloroprene Rubber (CR): Known for its balanced performance, offering oil resistance, ozone resistance, and aging durability in harmony.
EPDM Rubber (EPDM): Distinguished by its impressive high temperature tolerance (-50~150ºC) and robust weather resistance, making it ideal for long-term outdoor exposure.
Fluorine Rubber (FKM): Boasts exceptional high-temperature resilience (-20~250ºC) and chemical corrosion resistance, perfect for extreme environments.
Silastic (VMQ): Excels with high temperature durability (-70~300ºC), high transparency, and superb electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers superior resistance to strong acids and alkalis (including concentrated sulfuric and nitric acids) and excellent permeability resistance.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh to effectively prevent static accumulation, ensuring safety and functionality.
Fire Retardant Rubber: Infused with flame retardants (such as aluminum hydroxide), this material meets UL 94 flame retardant certification standards.
2. Structural Composition of Rubber Pipes
The Glue Layer: Engages directly with the conveying medium, showcasing features like 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 meticulously categorized into diverse types, including sandwich hoses, braided hoses, winding hoses, and full hoses.
4. Working Principle of Rubber Pipes
| 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 |

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. |
