Rubber tubing is an essential tubular product crafted primarily from robust rubber, typically featuring a dual-layered construction with an inner and outer layer, enhanced by a sturdy skeleton layer. This versatile product is adept at transporting gases, liquids, slurries, or granular materials efficiently. The core functionality of rubber tubing lies in its ability to seamlessly facilitate the transmission of various media, thanks to its remarkable elastic sealing and pressure-bearing capabilities. As a result, rubber tubing finds widespread applications across diverse fields such as industrial sectors, automotive engineering, and medical treatments, proving its indispensable nature.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its exceptional high elasticity, robust wear resistance, and superior bending and scratching characteristics, crude rubber is ideally suited for low pressure environments, offering flexibility and durability.
Protobutadiene Rubber (SBR): This material boasts excellent wear resistance and is economically favorable, making it a cost-effective choice. However, it has limited oil resistance, which should be considered in specific applications.
Cis-Polybutadiene (BR): Renowned for its impressive moisture resistance and outstanding performance in low temperatures, cis-polybutadiene remains elastic even at temperatures as low as -50ºC, making it ideal for challenging conditions.
Nitrile Rubber (NBR): Celebrated for its exceptional oil resistance, particularly against mineral and lubricating oils, nitrile rubber provides reliable performance. However, it may have lower ozone and high-temperature resistance.
Chloroprene Rubber (CR): This versatile rubber offers a well-balanced performance with oil, ozone, and aging resistance, making it suitable for a range of demanding applications.
EPDM Rubber (EPDM): With high temperature resistance ranging from -50 to 150ºC and strong weather resistance, EPDM is well-suited for long-term outdoor exposure, offering durability against the elements.
Fluorine Rubber (FKM): This robust material withstands high temperatures from -20 to 250ºC and offers excellent chemical corrosion resistance, making it ideal for extreme environments.
Silastic (VMQ): Known for its high temperature resistance between -70 and 300ºC, silastic provides high transparency and excellent electrical performance, catering to specialized requirements.
Chlorinated Sulfated Polyethylene Rubber (CSM): This material excels in resisting strong acids and alkalis, such as concentrated sulfuric and nitric acid, with superior permeability resistance.
Conductive Rubber: Engineered with built-in conductive fibers or metal mesh, this rubber effectively prevents static accumulation, ensuring safety in sensitive environments.
Fire Retardant Rubber: Infused with flame retardants like aluminum hydroxide, this rubber meets UL 94 flame retardant certification, offering enhanced safety against fire hazards.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This crucial layer directly contacts the conveying medium and is designed with wear and corrosion resistance, providing protection against 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 type delivers unique advantages tailored to specific applications.
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. |
