Rubber tubing is an essential tubular product, expertly crafted from high-quality rubber. It typically comprises a robust inner and outer rubber layer enhanced by a skeletal layer, designed for the efficient transport of gases, liquids, slurries, or granular materials. The core function of this versatile rubber tubing is to facilitate the seamless transmission of media, thanks to its elastic sealing and pressure-resistance capabilities. It has widespread applications across diverse sectors, including industry, automotive, and medical treatment, where reliability and performance are paramount.
1. Introduction of Rubber Pipe Materials
Crude Rubber: Exhibiting remarkable high elasticity, wear resistance, and superb bending and scratching characteristics, this type of rubber is ideally suited for low-pressure environments where flexibility and durability are key.
Protobutadiene Rubber (SBR): Renowned for its exceptional wear resistance and cost-effectiveness, SBR is a popular choice, although it offers less resistance to oils, making it suitable for specific applications.
Cis-Polybutadiene (BR): Known for its excellent moisture resistance and outstanding performance in low-temperature conditions, maintaining elasticity even at -50ºC.
Nitrile Rubber (NBR): Offers superior oil resistance, specifically against mineral and lubricating oils. However, it has limitations in ozone and high-temperature resistance.
Chloroprene Rubber (CR): Balances a variety of performance characteristics, including oil resistance, ozone resistance, and durability against aging, making it a well-rounded material choice.
EPDM Rubber (EPDM): Withstands high temperatures ranging from -50 to 150ºC and exhibits robust weather resistance, making it perfect for prolonged outdoor exposure.
Fluorine Rubber (FKM): Exceptionally resistant to high temperatures from -20 to 250ºC and chemical corrosion, making it ideal for use in extreme environments.
Silastic (VMQ): Known for its impressive high-temperature resilience from -70 to 300ºC and excellent electrical properties, in addition to its high transparency.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers strong resistance to harsh acids and alkalis such as concentrated sulfuric and nitric acids, along with excellent permeability resistance.
Conductive Rubber: Features built-in conductive fibers or metal mesh, effectively preventing static accumulation and ensuring safety in sensitive applications.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this rubber meets rigorous UL 94 flame retardancy standards for safety.
2. Structural Composition of Rubber Pipe
The Glue Layer: Directly interacting with the transport medium, this layer offers robust wear and corrosion resistance, effectively handling 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 various types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each tailored for specific uses and performance requirements.
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. |
