Rubber tubing is a versatile tubular product crafted primarily from rubber. It typically features an inner and outer rubber layer, accompanied by a strengthening skeleton layer. Its primary role is to seamlessly transport gases, liquids, slurries, or granular materials with efficiency. The core function of rubber tubing lies in its ability to facilitate the transmission of various media through its impressive elastic sealing and pressure-bearing capabilities. It's widely cherished across numerous fields, including the industrial sector, automotive industry, and medical treatment, due to its adaptability and reliability.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its high elasticity, remarkable wear resistance, and excellent bending and scratching characteristics, making it suitable for low-pressure environments.
Protobutadiene Rubber (SBR): Offers outstanding wear resistance and is cost-effective; however, it lacks oil resistance.
Cis-Polybutadiene (BR): Provides great moisture resistance and excels in low-temperature conditions, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR): Renowned for its exceptional oil resistance, particularly against mineral and lubricating oils, though it has weaker ozone and high-temperature resistance.
Chloroprene Rubber (CR): A well-rounded material with oil, ozone, and aging resistance, offering a balanced performance across the board.
EPDM Rubber (EPDM): Exhibits excellent high-temperature resistance (-50~150ºC) and robust weather resistance, ideal for consistent outdoor exposure.
Fluorine Rubber (FKM): Known for its high-temperature resilience (-20~250ºC) and remarkable resistance to chemical corrosion, suitable for extreme environments.
Silastic (VMQ): Offers superior high-temperature resistance (-70~300ºC), high transparency, and outstanding electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Excels in resisting strong acids and alkalis, such as concentrated sulfuric and nitric acid, with strong permeability resistance.
Conductive Rubber: Contains built-in conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Enhanced with flame retardants, such as aluminum hydroxide, and certified by UL 94 flame retardant standards.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly contacts the medium being conveyed, providing wear and corrosion resistance, including oil, acid, and alkali resistance.
| 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. |
