Rubber tubing is an essential tubular product, predominantly composed of rubber, featuring a dual-layer structure with an inner and outer rubber layer complemented by a skeleton layer. Its primary purpose is to proficiently transport gases, liquids, slurries, or granular materials. This versatile tubing excels in transmitting media, thanks to its remarkable elastic sealing and pressure-bearing capabilities. It finds widespread applications across diverse domains, including industry, automotive, and medical treatment, making it indispensable in facilitating seamless operations.
1. Introduction to Rubber Pipe Material
Crude Rubber: Renowned for its exceptional elasticity, remarkable wear resistance, and superb bending and scratching characteristics, this material is ideal for low-pressure environments, ensuring durability and flexibility.
Protobutadiene Rubber (SBR): This material offers outstanding wear resistance at a cost-effective price, though it has limitations in oil resistance, making it suitable for specific applications.
Cis-Polybutadiene (BR): Featuring impressive moisture resistance and exceptional low-temperature resilience, this material remains elastic even at temperatures as low as -50ºC, ensuring reliability in cold conditions.
Nitrile Rubber (NBR): Known for its excellent oil resistance, particularly against mineral and lubricating oils, this material exhibits some limitations in ozone and high-temperature resistance.
Chloroprene Rubber (CR): This versatile material boasts a balanced performance profile with oil resistance, ozone resistance, and resistance to aging, making it suitable for various applications.
EPDM Rubber (EPDM): With a high-temperature resistance range of -50~150ºC and robust weather resistance, this material is perfect for long-term outdoor exposure.
Fluorine Rubber (FKM): Featuring high-temperature resistance from -20~250ºC and excellent chemical corrosion resistance, this material can withstand extreme environments.
Silastic (VMQ): Known for its high-temperature resistance from -70~300ºC, high transparency, and superb electrical performance, this material is ideal for demanding applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offering strong resistance to concentrated acids and alkalis, along with excellent permeability resistance, this material is designed for harsh chemical environments.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh, this material effectively prevents static accumulation, ensuring safety and reliability.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, this material meets UL 94 flame retardant certification, providing essential safety features.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This critical layer directly contacts the conveying medium, offering impressive wear and corrosion resistance, including resistance to oil, acid, and alkali substances.
| 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.
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. |
