Rubber tubing, an essential tubular marvel crafted predominantly from superior rubber materials, is ingeniously designed with an interior and exterior rubber layer, complemented by a durable skeleton layer. This versatile creation serves as a conduit for the seamless transport of gases, liquids, slurries, or granular materials. The primary function of rubber tubing is to facilitate the efficient transmission of media, thanks to its remarkable elastic sealing and exceptional pressure-bearing capabilities. This makes it an indispensable choice across a myriad of fields, including industrial applications, automotive engineering, and medical treatment, where reliability and performance are paramount.
1. Introduction of Rubber Pipe Materials
Crude Rubber: Boasting high elasticity, wear resistance, and exceptional bending and scratching characteristics, this material is perfectly suited for low-pressure environments, ensuring reliable and durable performance.
Protobutadiene Rubber (SBR): Known for its outstanding wear resistance and cost-effectiveness, this material is a popular choice despite its limited oil resistance, making it ideal for specific applications.
Cis-Polybutadiene (BR): This rubber exhibits excellent moisture resistance and remarkable low-temperature performance, maintaining its elasticity even at a chilling -50ºC, making it suitable for cold environments.
Nitrile Rubber (NBR): Renowned for its superb oil resistance, especially against mineral oils and lubricating oils, NBR is a top choice for applications requiring reliable oil resistance, though it has less ozone and high-temperature resistance.
Chloroprene Rubber (CR): This versatile material offers balanced performance with its oil resistance, ozone resistance, and aging resistance, making it a comprehensive solution for various industrial needs.
EPDM Rubber (EPDM): With its high temperature resilience ranging from -50 to 150ºC and superior weather resistance, EPDM is ideally suited for prolonged outdoor exposure, ensuring longevity and reliability.
Fluorine Rubber (FKM): Exceptionally resistant to high temperatures (-20 to 250ºC) and chemical corrosion, FKM is perfectly suited for extreme environments where durability is a must.
Silastic (VMQ): Offering high temperature resistance from -70 to 300ºC, this rubber is known for its high transparency and excellent electrical performance, making it a versatile choice for various applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): This robust material offers unparalleled resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, with strong permeability resistance.
Conductive Rubber: Equipped with embedded conductive fibers or metal mesh, this innovation prevents static accumulation, ensuring safety and performance in sensitive environments.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this material meets the rigorous UL 94 flame retardant certification, ensuring safety and compliance in demanding applications.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This crucial layer comes into direct contact with the conveying medium, offering remarkable wear and corrosion resistance, including resistance to oils, acids, and alkalis, for long-lasting performance.
| 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. Rubber pipes are structurally categorized into a range of innovative types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each designed for specific applications and performance needs.
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. |
