Rubber tubing is an ingeniously crafted tubular product primarily made from the highest quality rubber, typically featuring both an inner and outer rubber layer, along with a robust skeleton layer for enhanced durability. This marvel of engineering efficiently transports gases, liquids, slurries, or granular materials. The essential purpose of rubber tubing lies in its ability to seamlessly facilitate the transmission of media, thanks to its exceptional elastic sealing and pressure-bearing capabilities. Widely embraced across numerous sectors such as industry, automotive, and medical treatment, rubber tubing stands as a testament to versatile and reliable functionality.
1. Introduction of Rubber Pipe Material
Crude Rubber: Renowned for its remarkable high elasticity, wear resistance, and exceptional bending and scratching characteristics, crude rubber is the go-to choice for environments necessitating low pressure resilience.
Protobutadiene Rubber (SBR): Offering outstanding wear resistance and cost-effectiveness, SBR is a pragmatic choice, although it does show limitations in oil resistance.
Cis-Polybutadiene (BR): Known for its excellent moisture resistance and unparalleled low temperature resilience, retaining elasticity even at an impressive -50ºC.
Nitrile Rubber (NBR): Boasts superior oil resistance, adept at withstanding mineral and lubricating oils, though it has limited ozone and high temperature resistance.
Chloroprene Rubber (CR): Exhibits a harmonious balance of oil, ozone, and aging resistance, making it an all-round performer in diverse applications.
EPDM Rubber (EPDM): Withstands high temperatures ranging from -50 to 150ºC and exhibits robust weather resistance, ideal for prolonged outdoor exposure.
Fluorine Rubber (FKM): Resilient in high temperatures from -20 to 250ºC and possesses formidable chemical corrosion resistance, perfect for extreme environments.
Silastic (VMQ): With high temperature resilience from -70 to 300ºC, high transparency, and excellent electrical performance, it stands out in demanding applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers resistance to strong acids and alkalis, like concentrated sulfuric and nitric acids, and demonstrates strong permeability resistance.
Conductive Rubber: Incorporates built-in conductive fibers or metal mesh to effectively prevent static accumulation, ensuring safety and efficiency.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, this rubber has achieved the prestigious UL 94 flame retardant certification.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly contacting the conveying medium, it is engineered with impeccable wear resistance and corrosion resistance, excelling in oil, acid, and alkali conditions.
| casing pyl |
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 masterfully categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each serving 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. |
