Rubber tubing is a versatile tubular product crafted from high-quality rubber, typically consisting of an inner and outer rubber layer accompanied by a reinforcing skeleton layer. It serves as an efficient medium for transporting gases, liquids, slurries, or granular materials. The primary function of rubber tubing is to ensure seamless transmission of these media, leveraging its remarkable elastic sealing and pressure-bearing capabilities. It finds extensive applications across diverse fields such as industry, automotive, and medical treatment, underscoring its indispensable utility.
1. Introduction to Rubber Pipe Materials
Crude Rubber: Known for its superior elasticity, wear resistance, and flexibility, this material is perfect for environments with low pressure demands. Its ability to withstand bending and scratching makes it a reliable choice.
Protobutadiene Rubber (SBR): Offers excellent wear resistance at a cost-effective price point, although it has limited oil resistance. Ideal for applications prioritizing durability over oil exposure.
Cis-Polybutadiene (BR): Excels with its moisture resistance and outstanding low temperature resilience, remaining elastic even at -50ºC, making it ideal for cold climate applications.
Nitrile Rubber (NBR): Praised for its excellent oil resistance, particularly against mineral and lubricating oils, though it has limited ozone and high temperature resistance.
Chloroprene Rubber (CR): Strikes a balance with its oil, ozone, and aging resistance, delivering a comprehensive performance for a variety of conditions.
EPDM Rubber (EPDM): Renowned for high temperature resistance (-50~150ºC) and robust weather resistance, this material is ideal for long-term outdoor exposure.
Fluorine Rubber (FKM): Withstands high temperatures (-20~250ºC) and offers chemical corrosion resistance, making it suitable for challenging environments.
Silastic (VMQ): Exceptional for high temperature conditions (-70~300ºC), notable for its high transparency and excellent electrical properties.
Chlorinated Sulfated Polyethylene Rubber (CSM): Exceptional resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, with strong permeability resistance.
Conductive Rubber: Embedded conductive fibers or metal mesh to effectively prevent static accumulation, ensuring safety in sensitive environments.
Fire Retardant Rubber: Infused with flame retardants like aluminum hydroxide, this material meets UL 94 flame retardant certifications for enhanced safety.
2. Structural Composition of Rubber Pipe
The Glue Layer: This layer is in direct contact with the media being transported, offering exceptional wear and corrosion resistance, including 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 categorized into diverse types, such as sandwich hoses, braided hoses, winding hoses, and full hoses, each designed 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. |
Harnessing advanced production technology and extensive technical expertise, we can customize a wide range of rubber products in various specifications and materials, ensuring quality and precision.
