Rubber tubing is a sophisticated tubular creation primarily crafted from resilient rubber. It typically features an inner and outer rubber layer, bolstered by a robust skeleton layer. Designed to smoothly transport gases, liquids, slurries, or granular materials, its core functionality lies in its exceptional ability to facilitate media transmission through elastic sealing and pressure-bearing capabilities. This versatile tubing finds widespread application across diverse fields, including industry, automotive sectors, and medical treatment, reflecting its indispensable role in modern technology.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its remarkable elasticity, wear resistance, and resilience against bending and scratches, this material is ideal for low-pressure environments.
Protobutadiene Rubber (SBR): Offers excellent wear resistance and cost-effectiveness, though its oil resistance is limited.
Cis-Polybutadiene (BR): Boasting impressive moisture resistance and outstanding performance in low-temperature conditions, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR): Renowned for its superior oil resistance, particularly against mineral and lubricating oils, albeit with lower ozone and high-temperature resistance.
Chloroprene Rubber (CR): Presents a balanced profile of oil resistance, ozone resistance, and aging resistance, making it a well-rounded choice.
EPDM Rubber (EPDM): Endures high temperatures ranging from -50 to 150ºC and offers strong weather resistance, perfect for prolonged outdoor exposure.
Fluorine Rubber (FKM): Withstands high temperatures between -20 to 250ºC and resists chemical corrosion, suited for extreme environments.
Silastic (VMQ): Excels in high-temperature resilience, enduring -70 to 300ºC, while providing high transparency and excellent electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Exhibits robust resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, with excellent permeability resistance.
Conductive Rubber: Integrated with conductive fibers or metal mesh to effectively prevent static accumulation, ensuring safe operations.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, meeting the stringent UL 94 flame retardant certification standards for safety.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly interfaces with the conveying medium, offering outstanding wear, corrosion, oil, acid, and alkali resistance for optimal performance.
| 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 categorized into a variety of types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each designed for specific applications.
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. |
