Rubber tubing is a marvel of modern material science, crafted primarily from rubber and usually featuring a sophisticated structure of both inner and outer layers, complemented by a robust skeleton layer. This ingenious product facilitates the seamless transportation of gases, liquids, slurries, or granular materials. With its primary function to effectively transmit media, the elastic sealing and pressure-bearing capabilities of rubber tubing make it indispensable across a multitude of industries, including automotive and medical sectors.
1. Introduction to the Material Wonders of Rubber Pipe
Crude rubber: Renowned for its remarkable elasticity, this material excels in wear resistance, and boasts exceptional bending and scratching characteristics, making it an ideal choice for low-pressure environments.
Protobutadiene rubber (SBR): Offering superior wear resistance and cost-effectiveness, SBR is a practical solution, though it presents certain limitations in oil resistance.
Cis-polybutadiene (BR): This material shines with its excellent moisture resistance and outstanding performance in low-temperature conditions, maintaining elasticity even at chilling temperatures of -50ºC.
Nitrile rubber (NBR): Lauded for its exceptional oil resistance, particularly against mineral and lubricating oils, NBR does have some weaknesses, namely in ozone resistance and high-temperature performance.
Chloroprene rubber (CR): Known for its balanced attributes, CR offers notable resistance to oil, ozone, and aging, presenting a comprehensive performance package.
EPDM Rubber (EPDM): This material stands out with its impressive resistance to high temperatures ranging from -50 to 150ºC and boasts strong weather resistance, suitable for prolonged outdoor applications.
Fluorine rubber (FKM): With its high temperature resilience, enduring up to 250ºC, and formidable chemical corrosion resistance, FKM is perfect for extreme environments.
Silastic (VMQ): Offering remarkable high temperature resistance between -70 and 300ºC, VMQ also features high transparency and unparalleled electrical performance.
Chlorinated sulfated polyethylene rubber (CSM): This material excels in resisting strong acids and alkalis, such as concentrated sulfuric and nitric acids, while also providing strong impermeability.
Conductive rubber: Ingenious integration of conductive fibers or metal mesh within the material prevents static accumulation, ensuring safety and reliability.
Fire retardant rubber: Enhanced with flame retardants such as aluminum hydroxide, this type of rubber has successfully passed UL 94 flame retardant certification, ensuring safety in challenging conditions.
2. Structural Composition of the Rubber Pipe
The glue layer: This critical component is in direct contact with the medium being conveyed and is designed with superior wear and corrosion resistance, capable of enduring substances like oils, acids, and alkalis.
| 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 ingeniously categorized into a variety of types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each offering unique benefits.
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. Diverse 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 Assurances:
| 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. |
With cutting-edge production equipment and a wealth of technical expertise, we are poised to soak up rubber and plastic products, offering customized solutions across a broad spectrum of specifications and materials in rubber products.
