Rubber tubing is a vital component in various industries, crafted primarily from rubber. This tubular marvel consists of an inner and outer rubber layer, complemented by a supportive skeleton layer, designed to transport a diverse range of media such as gases, liquids, slurries, or granular materials. The core functionality of rubber tubing lies in its exceptional ability to transmit media, thanks to its elastic sealing and pressure-bearing capabilities. Its versatility and reliability make it indispensable in fields such as industry, automotive, and medical treatment.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its remarkable elasticity, wear resistance, and ability to withstand bending and scratching, crude rubber is ideal for low-pressure environments.
Protobutadiene Rubber (SBR): This material boasts excellent wear resistance and is cost-effective, though it has limitations in oil resistance.
Cis-Polybutadiene (BR): Renowned for its superior moisture resistance and exceptional performance at low temperatures, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR): Offers outstanding oil resistance, especially against mineral and lubricating oils, but exhibits limited ozone and high temperature resistance.
Chloroprene Rubber (CR): Provides a balanced performance with its oil, ozone, and aging resistance, making it a comprehensive choice.
EPDM Rubber (EPDM): Withstands high temperatures ranging from -50 to 150ºC and boasts strong weather resistance, perfect for long-term outdoor exposure.
Fluorine Rubber (FKM): Known for its high temperature tolerance (-20 to 250ºC) and chemical corrosion resistance, suitable for extreme environments.
Silastic (VMQ): Offers remarkable high temperature resistance (-70 to 300ºC), high transparency, and excellent electrical properties.
Chlorinated Sulfated Polyethylene Rubber (CSM): Excels in resisting strong acids and alkalis, such as concentrated sulfuric and nitric acids, and offers robust permeability resistance.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, it meets the stringent UL 94 flame retardant certification standards.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This layer is in direct contact with the conveyed medium, providing essential wear and corrosion resistance, including resistance to oils and acids.
| 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 various types, including sandwich hoses, braided hoses, winding hoses, and full hoses.
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. |
