Rubber tubing is a versatile and essential product primarily crafted from high-quality rubber. It typically comprises an inner and outer rubber layer, along with a robust skeleton layer, offering unparalleled functionality for transporting gases, liquids, slurries, or granular materials. Its core competency lies in its remarkable ability to transmit media seamlessly, thanks to its elastic sealing and pressure-bearing attributes. This makes it an indispensable element across diverse sectors, including industry, automotive, and medical treatment, where efficiency and reliability are paramount.
1. Introduction of rubber pipe material
Crude rubber: Known for its exceptional elasticity, wear resistance, and ability to withstand bending and scratching, it is ideally suited for low-pressure environments where durability is key.
Protobutadiene rubber (SBR): A cost-effective solution offering excellent wear resistance, though it may fall short in oil resistance, making it a popular choice for budget-conscious applications.
Cis-polybutadiene (BR): Renowned for its superior moisture resistance and remarkable performance in low temperatures, maintaining elasticity even at -50ºC, it's perfect for cold environments.
Nitrile rubber (NBR): Offers outstanding oil resistance, particularly against mineral and lubricating oils, although it may be less effective against ozone and high temperatures.
Chloroprene rubber (CR): Balances oil resistance, ozone resistance, and aging resistance, delivering a well-rounded performance ideal for comprehensive use.
EPDM Rubber (EPDM): Withstands high temperatures ranging from -50ºC to 150ºC and boasts strong weather resistance, making it perfect for prolonged outdoor exposure.
Fluorine rubber (FKM): With high resistance to temperatures ranging from -20ºC to 250ºC and chemical corrosion, it is engineered for extreme environments.
Silastic (VMQ): Excels in high temperature environments from -70ºC to 300ºC, known for its high transparency and superb electrical performance.
Chlorinated sulfated polyethylene rubber (CSM): Demonstrates robust resistance to strong acids and alkalis, such as concentrated sulfuric and nitric acid, along with strong permeability resistance.
Conductive rubber: Integrates conductive fibers or metal mesh to effectively prevent static accumulation, ensuring safety and functionality.
Fire retardant rubber: Enhanced with flame retardants like aluminum hydroxide, this material has earned the UL 94 flame retardant certification, ensuring top-notch safety standards.
2. Structural composition of the rubber pipe
The glue layer: Comes in direct contact with the conveying medium, offering superior wear resistance and corrosion resistance, including oil, acid, and alkali resistance.
| 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. |
Harness advanced production technology and extensive technical expertise to craft a wide array of customizable rubber and plastic products tailored to diverse specifications and materials.
