Rubber tubing is an essential tubular product crafted primarily from rubber, comprised typically of an inner and outer rubber layer, complemented by a reinforcing skeleton layer. This versatile tubing is adept at transporting a variety of media, such as gases, liquids, slurries, or granular materials. At its core, the function of rubber tubing is to facilitate seamless transmission of media through its remarkable elastic sealing and pressure-bearing capabilities. It finds extensive use across diverse fields, including industry, automotive, and medical treatment, underscoring its indispensable role in modern technological landscapes.
1. Introduction of Rubber Pipe Material
Crude Rubber: Renowned for its high elasticity, this material boasts exceptional wear resistance, coupled with admirable bending and scratching characteristics. It is ideally suited for applications in low pressure environments.
Protobutadiene Rubber (SBR): This material offers excellent wear resistance and is cost-effective. However, it exhibits poor resistance to oils, indicating a trade-off in specific applications.
Cis-Polybutadiene (BR): Known for its admirable moisture resistance, this material shines with outstanding low temperature resilience, maintaining elasticity even at a chilling -50ºC.
Nitrile Rubber (NBR): Praised for its excellent oil resistance, particularly effective against mineral oils and lubricating oils. However, it demonstrates weak resistance to ozone and high temperatures.
Chloroprene Rubber (CR): Offers a balanced performance with resilience to oil, ozone, and aging, making it versatile for various applications.
EPDM Rubber (EPDM): Distinguished by its high temperature resistance ranging from -50~150ºC and robust weather resistance, this material is perfect for long-term outdoor exposure.
Fluorine Rubber (FKM): With its high temperature threshold of -20~250ºC and resistance to chemical corrosion, this material is ideal for extreme environmental conditions.
Silastic (VMQ): Characterized by its exceptional high temperature resistance (-70~300ºC), this material also features high transparency and superior electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Known for its formidable resistance to strong acids and alkalis, such as concentrated sulfuric and nitric acids, alongside robust permeability resistance.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh, this material effectively prevents static accumulation.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this material has passed the UL 94 flame retardant certification, ensuring safety and security.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This layer is in direct contact with the conveyed medium and is engineered to offer wear resistance and corrosion resistance, such as resistance to 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 classified into a myriad of types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each tailored 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. |
