Rubber tubing is an exceptional tubular product, primarily crafted from high-quality rubber. It typically features a robust inner and outer rubber layer, alongside a sturdy skeleton layer. This engineering marvel is expertly designed to transport an array of substances including gases, liquids, slurries, or granular materials with ease. The core function of rubber tubing lies in its ability to facilitate seamless media transmission, thanks to its superior elastic sealing and impressive pressure-bearing capabilities. It finds broad application across diverse fields such as industry, automotive, and medical treatment, ensuring reliability and efficiency wherever employed.
1. Introduction to Rubber Pipe Material
Crude Rubber: This material boasts remarkable high elasticity, coupled with superior wear resistance, bending, and scratching characteristics, making it ideally suited for low-pressure environments.
Protobutadiene Rubber (SBR): Known for its outstanding wear resistance and cost-effectiveness, though it has limited oil resistance capabilities.
Cis-Polybutadiene (BR): Offers exceptional moisture resistance and superb low-temperature resilience, retaining elasticity even at a chilling -50ºC.
Nitrile Rubber (NBR): Renowned for its excellent oil resistance, particularly against mineral and lubricating oils, though it exhibits weaker ozone and high-temperature resistance.
Chloroprene Rubber (CR): Delivers a balanced performance with oil, ozone, and aging resistance, catering to a wide range of applications.
EPDM Rubber (EPDM): Exhibits high temperature stability (-50~150ºC) and superior weather resistance, making it perfect for prolonged outdoor use.
Fluorine Rubber (FKM): Engineered for high-temperature endurance (-20~250ºC) and excellent chemical corrosion resistance, ideal for extreme environments.
Silastic (VMQ): Known for its exceptional high temperature resistance (-70~300ºC), remarkable transparency, and outstanding electrical performance.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers robust resistance to strong acids and alkalis, including concentrated sulfuric and nitric acids, with exceptional permeability resistance.
Conductive Rubber: Features built-in conductive fibers or metal mesh to effectively prevent static accumulation, enhancing safety and reliability.
Fire Retardant Rubber: Infused with flame retardants, such as aluminum hydroxide, it meets UL 94 flame retardant certification, ensuring safety in hazardous environments.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This crucial component is 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 ingeniously categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses, each serving unique purposes.
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. |
