Rubber tubing is a highly versatile tubular product crafted primarily from rubber. It typically consists of an inner and outer rubber layer, complemented by a sturdy skeleton layer. Designed to transport gases, liquids, slurries, or granular materials, its core function is to efficiently facilitate the transmission of media through its exceptional elastic sealing and pressure-bearing capabilities. This makes it an indispensable tool across a plethora of fields, including industry, automotive, and medical sectors.
1. Introduction of Rubber Pipe Material
Crude rubber: Known for its remarkable high elasticity, exceptional wear resistance, and ability to withstand bending and scratching, this material is ideally suited for low-pressure environments.
Protobutadiene rubber (SBR): Offers outstanding wear resistance and is economically viable, though it has less effective oil resistance.
Cis-polybutadiene (BR): Renowned for its excellent moisture resistance and remarkable low-temperature flexibility, remaining elastic even at -50ºC.
Nitrile rubber (NBR): Excels in oil resistance, particularly against mineral oils and lubricating oils, but demonstrates weaker ozone and high temperature resistance.
Chloroprene rubber (CR): Balances oil, ozone, and aging resistance with a comprehensive performance profile.
EPDM Rubber (EPDM): Offers impressive high-temperature resistance (-50 to 150ºC) and strong weather resistance, making it ideal for prolonged outdoor use.
Fluorine rubber (FKM): Features exceptional high-temperature resistance (-20 to 250ºC) and chemical corrosion resistance, making it suitable for extreme environments.
Silastic (VMQ): Stands out with high-temperature tolerance (-70 to 300ºC), high transparency, and excellent electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Provides strong resistance to concentrated acids and alkalis, coupled with superior permeability resistance.
Conductive rubber: Incorporates built-in conductive fibers or metal mesh to effectively prevent static accumulation.
Fire Retardant Rubber: Enriched with flame retardants like aluminum hydroxide and certified by UL 94 flame retardant standards.
2. Structural Composition of the Rubber Pipe
The Glue Layer: Directly interfaces with the conveyed medium, offering robust 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 diverse types such as 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. |
