Rubber tubing is a versatile and essential tubular product crafted primarily from top-quality rubber. This sophisticated product typically comprises an inner and outer rubber layer, elegantly reinforced by a skeleton layer. It serves as a vital conduit for transporting gases, liquids, slurries, or granular materials with remarkable efficiency. At its core, rubber tubing excels in transmitting media seamlessly through its exceptional elastic sealing and pressure-bearing capabilities. This makes it indispensable across diverse fields such as industry, automotive, and healthcare, where reliability and performance are paramount.
1. Introduction of rubber pipe material
Crude Rubber: Revered for its remarkable high elasticity, this material boasts exceptional wear resistance, superb bending, and scratch-resistant characteristics. It's perfectly suited for applications in low-pressure environments where durability is key.
Protobutadiene Rubber (SBR): Renowned for its outstanding wear resistance and cost-effectiveness, SBR is a popular choice. However, it is important to note its limited oil resistance, which may influence its application in certain scenarios.
Cis-Polybutadiene (BR): This material offers impressive moisture resistance and excels in low-temperature environments, maintaining elasticity even at -50ºC, making it ideal for cold climate applications.
Nitrile Rubber (NBR): Known for its superior oil resistance, NBR performs exceptionally well with mineral and lubricating oils. However, it is less effective against ozone and high-temperature conditions.
Chloroprene Rubber (CR): This material showcases a harmonious balance of oil resistance, ozone resistance, and aging resistance, delivering a comprehensive performance suitable for various applications.
EPDM Rubber (EPDM): With its impressive high-temperature resistance ranging from -50ºC to 150ºC and robust weather resistance, EPDM is tailored for enduring long-term outdoor exposure.
Fluorine Rubber (FKM): Offering exceptional high-temperature resistance from -20ºC to 250ºC and unparalleled chemical corrosion resistance, FKM is designed for the harshest and most challenging environments.
Silastic (VMQ): This high-performance material thrives in extreme temperatures from -70ºC to 300ºC. Its high transparency and excellent electrical performance make it a top choice for specialized applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Known for its robust resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, CSM also boasts superior permeability resistance.
Conductive Rubber: Engineered with embedded conductive fibers or metal mesh, this material effectively prevents static accumulation, making it a safe choice for sensitive applications.
Fire Retardant Rubber: Enhanced with flame retardants such as aluminum hydroxide, this material meets the stringent UL 94 flame retardant certification, ensuring safety in fire-prone environments.
2. Structural composition of the rubber pipe
The Glue Layer: In direct contact with the conveying medium, this layer boasts exceptional wear resistance and corrosion resistance, providing protection against oil, 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 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. |
