Rubber tubing, a marvel of modern engineering, is primarily composed of resilient rubber materials, featuring an intricate inner and outer rubber layer accompanied by a robust skeleton layer. This sophisticated tubing is engineered to efficiently transport gases, liquids, slurries, or granular materials with unparalleled precision. Its core function extends beyond mere conveyance, as it harnesses the power of elastic sealing and pressure-bearing capabilities to ensure seamless media transmission. This makes rubber tubing indispensable across a diverse range of fields, including industrial applications, the automotive industry, and medical treatments.
1. Introduction of Rubber Pipe Materials
Crude Rubber: With its remarkable high elasticity, exceptional wear resistance, and superior bending and scratching characteristics, crude rubber is ideally suited for environments demanding low-pressure endurance.
Protobutadiene Rubber (SBR): Known for its exceptional wear resistance and cost-effectiveness, SBR is an economical choice, though it exhibits a lower resistance to oil.
Cis-Polybutadiene (BR): Renowned for its excellent moisture resistance and extraordinary resilience at low temperatures, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR): With outstanding resistance to oil, particularly mineral and lubricating oils, NBR is a top choice, despite its comparatively weaker ozone and high-temperature resistance.
Chloroprene Rubber (CR): Praised for its balanced performance, CR offers oil resistance, ozone resistance, and aging resistance, maintaining a harmonious blend of these key attributes.
EPDM Rubber (EPDM): This material boasts impressive high-temperature tolerance ranging from -50 to 150ºC, along with strong weather resistance, making it ideal for long-term outdoor applications.
Fluorine Rubber (FKM): FKM excels in high-temperature environments, withstanding temperatures from -20 to 250ºC, and offers robust chemical corrosion resistance, perfect for extreme conditions.
Silastic (VMQ): This material is celebrated for its exceptional high-temperature resilience, ranging from -70 to 300ºC, coupled with high transparency and outstanding electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): CSM is valued for its resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, alongside its strong impermeability.
Conductive Rubber: Featuring built-in conductive fibers or metal mesh, this rubber effectively prevents static accumulation, ensuring safe and reliable operation.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this rubber has passed UL 94 flame retardant certification, ensuring superior safety.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly interfaces with the conveyed medium, offering unmatched wear resistance and corrosion protection, including resistance to oil, acids, and alkalis.

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 a Range of Types: These include sandwich hoses, braided hoses, winding hoses, and fully enveloping hoses, each designed to meet specific needs.
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. |
