Rubber tubing is an elastomeric marvel primarily crafted from rubber. It typically comprises an inner and outer rubber layer, along with a robust skeleton layer. This versatile tubular product is designed to transport gases, liquids, slurries, or granular materials effortlessly. The primary function of rubber tubing lies in its ability to facilitate the smooth transmission of media, thanks to its elastic sealing and pressure-bearing capabilities. It finds extensive applications across various fields, including industry, automotive, and medical treatment, showcasing its diverse utility and reliability.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its remarkable high elasticity, this material excels in wear resistance, bending, and scratching characteristics. It is ideally suited for low-pressure environments, offering superb durability and flexibility.
Protobutadiene Rubber (SBR): This rubber boasts excellent wear resistance at a low cost, making it an economical choice. However, it has limited oil resistance, which should be considered for specific applications.
Cis-Polybutadiene (BR): Renowned for its exceptional moisture resistance, this rubber maintains outstanding elasticity even at low temperatures, down to -50ºC.
Nitrile Rubber (NBR): With superior oil resistance, NBR excels against mineral oils and lubricating oils. However, it offers limited resistance to ozone and high temperatures.
Chloroprene Rubber (CR): This rubber delivers a balanced performance with oil resistance, ozone resistance, and aging resistance, making it a reliable choice for various applications.
EPDM Rubber (EPDM): High-temperature resistance ranging from -50~150ºC and strong weather resistance make this rubber ideal for prolonged outdoor exposure.
Fluorine Rubber (FKM): With an impressive temperature resistance from -20~250ºC and chemical corrosion resistance, FKM is suitable for the most extreme environments.
Silastic (VMQ): Offering high-temperature resistance from -70~300ºC, high transparency, and excellent electrical performance, silastic is versatile and reliable.
Chlorinated Sulfated Polyethylene Rubber (CSM): Known for its resistance to strong acids and alkalis, CSM provides robust permeability resistance, making it ideal for harsh chemical environments.
Conductive Rubber: Integrated with conductive fibers or metal mesh, this rubber prevents static accumulation, ensuring safety and reliability.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this rubber meets stringent UL 94 flame retardant certification standards.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This layer comes into direct contact with the conveying medium, offering superior 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, each designed for specific needs and 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. |
