Rubber tubing is a highly versatile tubular product crafted primarily from superior rubber materials, generally encompassing an inner and outer rubber layer, augmented by a robust skeleton layer. Its exemplary function is to transport gases, liquids, slurries, or granular materials with unmatched efficiency. The core virtue of rubber tubing lies in its unparalleled ability to facilitate the smooth transmission of media through its elastic sealing and pressure-bearing capabilities. This makes it an indispensable component across a myriad of sectors, including industry, automotive, and medical treatments.
1. Introduction to Rubber Pipe Materials
Crude Rubber: Renowned for its high elasticity, remarkable wear resistance, and outstanding bending and scratching capabilities, crude rubber is the ideal choice for environments requiring low-pressure conditions.
Protobutadiene Rubber (SBR): This material boasts excellent wear resistance and is cost-effective, though it has limited oil resistance, making it suitable for applications where oil exposure is minimal.
Cis-Polybutadiene (BR): Known for its superior moisture resistance and exceptional performance in low temperatures, maintaining elasticity even at a chilling -50ºC.
Nitrile Rubber (NBR): Offers outstanding resistance to various oils, including mineral and lubricating oils, though it is less resistant to ozone and high temperatures.
Chloroprene Rubber (CR): This well-rounded material balances oil resistance, ozone resilience, and aging resistance, providing comprehensive performance for diverse applications.
EPDM Rubber (EPDM): With its remarkable high-temperature resistance ranging from -50 to 150ºC and formidable weather resilience, EPDM is perfect for prolonged outdoor exposure.
Fluorine Rubber (FKM): Excelling with high-temperature endurance from -20 to 250ºC and robust chemical corrosion resistance, FKM is crafted for extreme environmental conditions.
Silastic (VMQ): This premier material distinguishes itself with high-temperature resilience (-70 to 300ºC), superb transparency, and excellent electrical properties, making it ideal for demanding applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Known for its resistance to strong acids and alkalis, such as concentrated sulfuric and nitric acids, and its impermeability, CSM is indispensable in harsh chemical environments.
Conductive Rubber: Ingeniously designed with built-in conductive fibers or metal mesh, this rubber prevents static accumulation, ensuring safety and functionality.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this rubber meets UL 94 standards, ensuring optimal flame resistance and safety.
2. Structural Composition of Rubber Pipes
The Glue Layer: This layer is in direct contact with the conveyed medium, offering exceptional wear and corrosion resistance, 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 diversified into types such as sandwich hoses, braided hoses, winding hoses, and full hoses, each designed for specific applications and performance characteristics.
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. Key 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. |
